Just got one and put 4 button top protected 18650s in without selecting anything. All seems to be ok, green LEDs flashing to indicate charging. Going to be using this video as an instruction manual rather than the useless instructions. Many thanks for this video, much appreciated.
One of the worst Manuel's I've ever seen. I had no idea what the lights indicate. Or what the C and V buttons do. Personally I would rate this charger very low because of the lack of instructions or labeling on the charger itself.
I've had mine for just over a year now. Excellent piece of kit, never had a single issue (not even with the spring loaded contacts). Bought it with brand new HG2s and 25Rs, this device has been the sole charging method for these cells, they are still after a year of constant use (cells would cycled through and used within a max of 3 days of being fully charged to empty), functioning brilliantly (minus the normal degradation of capacity)
LUC V4 Efest charger is the best charger out there by far. Hands down, no contest worth every single penny and I'd still buy them if they doubled the price. Funny considering that i hate Efest batteries but i am in love with a charger from the same company, lol.
Great video. I've had the 'New i4" from Nitecore for a whole now. But recently had some NiCd AA batteries get (fairly) hot while charging. The charger didn't indicate they were bad. After trying to use the batteries however they went dead quick. Using the unit today, it's charging my assorted AA's fine, it seems, and they're not getting hot. Any way, generally my experience with the charger has been Very good. But at least once it was acting peculiar. I also charge 18650's, and it wonderful that it's completely plug and play. Although I did read the manual, and it does read like half dedicated stereo instructions at times.
I've been charging 3x 18650 Sony VTC5 2600mAh batteries and since I've gotten the charger it has gotten very hot while charging the batteries there has never been a point where I was able to run the charger with mind at peace without a fan blowing directly onto it for many hours, is this an issue with these chargers or is mine just broken?
The Dragon is good though costs quite a bit more. i4 is an affordable charger so the two are quite different. I think the D4 is now too old to really consider (also doesn't have the faster charging this one does on a single slot)
I just bought this today as my very old 4bay nitecore charger's figure 8 connector deteriorated (did a great job). Currently charging 4 older 18650 batteries and set them to sequentially fast charge. Let's see if they haven't reinvented the wheel 🤔
There seems to be a variation in the product because mine had smooth lugs on the negative sliding bracket which often would not make contact with the negative end of the batteries. One had to jiggle the battery a bit to get then to touch the bracket, but they often work loose during charging and you return to find that you battery is as dead as when you started.
@@methodman5201 This video has recommended chargers I'm quite busy editing so can't answer more questions if it's on the list it's safe and will work great: czcams.com/video/Kmoo-_izexE/video.html
Coming from the I2.. I think the holding on this one is worse! it gets hotter and did the same test and am not too impressed. Might invest in a better charger as these rare sony batteries were hard to find genuine ones (not re-wrapped) so I would like to have them last as long as possible and the heating up is quite alarming. I do like that It does regular size rechargables
The raised contact points can mean cells can sometimes slip off (button top ones). I'm not sure if the design has changed since I looked at it, there is a bit of heat to get rid off perhaps a bit more case ventilation would have helped
i have the two slot one and the left side only gets to half while the right side goes to fully charged. im now looking for a better charger. bad part this is only a week old but bought it when i was out of town. thank you for your video.
Is it a real nitecore? You should have a warranty with it. Whilst the Ni-MH charging isn't great on this for Li-ion it's acceptable shouldn't half charge a bay
I was looking for a charger for my 18650/RCR123 batteries, and somewhere deep in my mind I heard a voice saying "find Mr Baz channel!" 😂 I guess that means I trust your reviews! 😉 (It's either that or I'm having a psychosis....? 🤔 🤷🏻♂️ Oh well! At least my flashlight is working! 🔦😊)
Did u buy it ? I m looking for the same brand too but i heard it gets too hot when it s charging and also i found another brand golisi i4 ? Which is better
Excellent information on the New i4 charger. My understanding is lithium batteries will last longer (more charge cycles) if charge is just shy of 4.2V as your video shows. The slight loss of power should not be noticeable. The NiMh batteries get quite hot in this charger. The heat can not be good for them so I will not allow overnight charging.
Yes that is true with regard charging cycles, not a bad thing to be a little under the 4.2v... the problem isn't the Li-ion charging it's the Ni-MH heat and termination. It's better than the new i2 which was under the 4.15V at times. I'm not overly impressed with the Ni-MH side of things, few chargers heat batteries that much which isn't good for them (leaving aside the lower voltage readings which can vary a bit). It's not a fast charging rate, the Opus C3100 can charge Ni-MH at 1 amp across 4 cells and they remain pretty cool. Perhaps the design isn't allowing enough airflow to the transformer
i found out the 18650 batteries on mine dont get hot only the case gets hot on mine but maybe my AA batteries get a little warm .but i have got a fast charger for my AA and AAA batteries that get realy hot nowt like the nitecore
Hi the 18650's are a fair bit larger so don't have the same heat build up. AA's do even with all 4 bays in use, charge rate isn't high either. A lot of fast chargers do, but the Opus BTC3100 doesn't because it's got a fan. D4 doesn't have any obvious heat build up even at the same charging rate for AA's (ie all 4 in use 375mA). Case probably needs more ventilation slots
Hi Baz, Subsequent charges of NiMh cells don't show heat build up the first charge did on new cells that had been in storage over a year . Charge voltage is 1.405 so I'm happy with the charger. Voltage on the Li cells end up at 4.02 volts so again all is good as far as my low current use. Only thing is the "V" button seems to have zero effect. anyway thanks for your observations and good video. Bye. Jim
I have older version of i4 for some time and I figure out when I use 12V adapter it heat much less(about half less) than with standard plug when it need to use internal transformer, so it could be heat by transformer.
@@MrBazReviews Since I figure it out I'm using it only with 12V adapter. In my country I can get used 12V 1-2A adapter for 2€, it's easy to replace it when it broken, and I think charger would last longer because less heating. I used very old Nitecore i4(maybe first version), and when it broken I get 2014 version and now I'm using it. When it get broken I will get 2016 version which you reviewed. Charging Ni-Mh AA/AAA and 18650 batteries with it, good charger for it's price, I'm really sattisfied. BTW. I'm also using Eneloop Ni-Mh AA and AAA batteries, they're fantastic.
@@MrBazReviews It could be. 2014, than 2016, and now after 3+ years no new version, so it's time to release new version. However I won't buy new as long this works. When this 2014 version get broken I will get newest available.
Love the charger. Charging LG 4X 18650 3000mAh 3.7V. The first time i charged the batteries took some 18hrs. Now im just going to keep changing the charge settings to have a lower charge so that the units last me a little longer. Thanx for the review. B.T.W. where can i get a car adapter for this device, OEM of course?
It happens with all cells, including the Eneloop so I think that's not likely the issue. I believe the problem is the design isn't great for getting rid of head (prob the built in transformer) It's not a high charging rate either
When charging one single cell, is there a way to set the charging current lower than 1.5A manually? I wasn't able to figure it out by reading the manual.
The default charging speed is 750mA for larger cells up to two (18650/26650) you have to set it manually for lower tthan 1.5amps if using a single cell. See 3:25 for the charging speeds
my cell is a 18650, once I insert it into a slot when no other cell is charging, the 1.5A led turns on automatically, so that means it's charging at 1.5A right? How can I turn that off in order to charge it slower?
Press the C button when you insert the cell to change the current from 1.5 to normal which is 0.75. It's quite safe to charge a single 18650 at 1.5amps that's about as high as you can charge without having any detrimental effect on recharge cycles.
@@ndrinks5550 the ones given with the istick pico 100w(AVB 21700 4000mah)don't fit in it...so yea. when i wrote that comment i didnt try other 21700's yet... so i admit it is wrong to say 21700 don't fit in it...but is wrong even to say"every 21700 fit in it"...im not the only one got problems with this common combo
@@alb12e345 I wonder what manufacturer the battery that comes with the iStick Pico is once unwrapped. It sounds like for whatever reason it is isn't sticking to the 21700 size spec, either that or just a really thick or perhaps even double wrap is the only reason I can think of. I'm really paranoid about battery safety though, extra width would make me suspicious even though the battery probably works fine.
They don't for Ni-MH there is nothing to change default is 0.5A charging. The only thing you can do with Ni-MH is battery activation with the charger holding both down at the same time enters that
Maybe it's just me, but @2:07 it seems like the slider has too much play. The top portion seems to move to the left quite a bit as you're pulling it down.
There is a bit of play, not that I've seen any problem when using it. I've seen better slider designs on some chargers don't think it's a major problem the new i2 wasn't nearly as smooth for the sliders.
i had the I2 and seemed LOT sturdier holding the batteries. I though this was my imagination. My I2 was great but fried it using it in the car on the 12v socket as I guess running the 14V was too much. If you want to use it in car make sure its 12V REGULATED as normally the few additional volts doesn't hurt most devices but these cannot tolerate it. 2 days using the new I4 and this was my biggest issue as it doesn't lock down as tight
Out of the blue mine has just stopped working completely not lights or anything, I've also tried different electric point's around the house and still nothing 😭😭😭😭😭
There seems to be something wrong with my Nitecore New i4. Yesterday when I inserted 2 batteries in slots 1 and 2 (L-to-R), the charging indicator LEDs started jumping up and down, but also the LEDs for slot 4 started flashing up/down, although there was no battery in slot 4. I don't understand these chargers and I was a bit spooked. Can you tell me what's wrong and if I should be worried?
@@saloscontent Activation press and hold both buttons to start that. Li-ion shouldn't often discharge to that point, so check the cells are in good condition
I just picked one of these up and plugged it into my power strip and it flashes once but then doesn't respond to the batteries insertion.. it works in the wall outlet.. must have a problem with my power strip? Or there's a loose connection and I got lucky
I can't remote troubleshoot problems, but if it works on one outlet and not another, that would kinda say to me there is nothing wrong with the charger, and something wrong with one power source ;-D
Hello, I have a question : when I charge my 18650 with the I4 and then put them in the D4, the are never fully charge. Around 4.10 instead of 4.20. Is the something I should do ? Thanks.
D4 should charge up to 4.18 or 4.19 least the ones I've used and tested do. If it's not there are only 2 things the charger (ie try it with other cells) or the battery is worn out. Sometimes worn cells won't hit get up to a full charge I'm not sure how old it is or it's but I've seen it on other Li-ion cells that won't get up to full voltage
@@MrBazReviews Thanks for your answer. Actuality, my D4 works perfectly, I use it to test the charge of the batteries I have charged with the I4. The I4 only charges the batteries up to 4.10.
@@Alexis_Wajdenbaum Must be faulty then it should at least hit 4.15 or above. Most Nitecore chargers go to about 4.17V it's common to be a little under the 4.20V
Shortens the life span over charging nothing bad likely to happen, unprotected cells can vent (but need to be higher than that), protected ones have a circuit that prevents charging above 4.25V
I guess I'm going with the xtar vc4 because the I-4 seems to have too many problems and overheats and I don't want no issues even though I rather had that because the LCD screen in real-time charging is what I want unfortunately You Can't Always Get What You Want so unless I want to pay top dollar I'll just settle for that
Is it correct that it can only fast charge one high capacity battery at a time? Because I just tried adding 1 additional battery and setting both to fast charge by pressing C and holding C as you explained, then 2 more, so a total of 4 at a time, and then all 4 red LED's were on.
It can only fast charge 1 bay at a time, what happens is it will switch over to the next cells and faster charge that when it has finished the first one, and the next one and so on
I have noticed that I can't change the the 1.5 amp down on single 18650 charge. After charging 1 battery I get 500 hits. If I charge the same battery with another which drops the amps, I get 800 hits. This automatic 1.5 amp is unacceptable to me as I feel that it is killing my cells and I use single cell MODs. I can't find a way to tell it to charge at lower amp for single.
Hold the C button down to get out of the 1.5A charge rate - the red light shows up by default for one cell for 1.5A charging. 1.5A is unlikely to hurt any 18650 for cycles, most of those high drain cells can charge at up to 4A (that def will impact cycles). Only the high capacity ones say 3500mAh have a recommended charging speed of 1.0A (they can take more that's their best speed to preserve cycles), other ones can charge way faster
@@MrBazReviews Thank you for responding but with 1 cell the hold C button does nothing and I definitely notice a huge use difference. It may not be hurting the total life of the cell but it is hurting the single charge usability. I actually thought my cells were dying after using this for the first time, but they are fine if I charge 2 or more cells in it. It seems that C button only works for making 1 of multiple cells to charge at 1.5 amps. I guess I will need to buy a single 18650 charger or one that gives better user control over possible trickle charge.
Hello mate, I wanna buy this charger for 21700 batteries for my vaping devices, but I also have a second options with XTAR VC4SL USB charger, which one of this chargers is better for highly-rated 21700 batteries (more than 4000mAh on 3.6V at 40A)? Tnx a lot and greetings from the Serbia...
@@MrBazReviews Tnx a lot, that newer XTAR VC4SL is exactly XTAR VC4 PLUS without wall adapter, everything else is the same. My third option is: CVEYG Q2 SMART LED charger...
Wondering if I can get your opinion. I bought this unit couple of years ago. I hadn't used it a great deal but now it has a smell like burnt wiring and a little warm. The 1 light is blinking in all 4 batteries but it doesn't seem to be charging. Could it be the charger or maybe the batteries. The batteries are cool as well. Or do you think I should get another charger and batteries
is it possible to manually select the amps? asides from the 1.5 fast charge for single battery charging. I was told charging batteries at a slower rate would increase the life
Hi Garth you can manually set the charging for a cell such as a 18650 to 0.75A from 1.5A (which is the default). It doesn't have a "low" charging mode like the D4 though where you could set individually lower charging current per channel regardless of battery type. If you are using smaller cells such as AA/AAA's, 18350's etc then the default charging speed is 0.5A or 0.375 if using all 4 bays. Hope that helps a bit
How long should i expect it to take to charge four 18650 drained battery's? Should i adjust anything or just set it and forget it cause so far all i see is 4 flashing lights on the bottom...
Hi charging rate is 0.375a for four cells so it's going to take a while to charge all 4 bays with 18650's (depends on capacity around 7-9 hours). You can charge one cell at 1.5a that's about as fast as it goes or charge in sequence at 1.5 amps moving to the next slot. 2 slots can charge at the same time at a rate of 0.75a. It's not a fast charger for multiple cells ie 3/4 at the same time.
Interesting I think really the case could do with a re-design as it's meant to lay flat. D4 doesn't pump heat anywhere near this level maybe a MKII will address the weaker points. That said it's working fine so far
Getting a hot plastic smell from mine. I don't use it often, because I'm paranoid it's going to burst into flames. It should be fine, as my Samsung 25R 18650's are compatible.
I'd be surprised if there's a major issue like bursting into flames, there is heat build up - but the transformer is built into the unit hence it's likely to be warmer. Evidently they are covered via a worldwide insurance no idea if anyone has ever claimed off of it or how useful it is. My main grumble is heat on smaller cells Ni-MH, the Li-ion charging is reasonable hence I'd suggest the D4 for users with mixed cell types despite the slower speed for single battery charging
Im charging 3 18650 hohm life batteries as i type. There is solid green lights on bottom and blinking lights on second row. Does that mean its charging? Or is there something wrong?
Wow, mine is exactly the same, SUPER HOT! To the point that I stopped using it. Is it ok to use it like this, is it dangerous? I definitely CAN'T keep my finger on it HOT!
I think it's more a problem with Ni-MH cells ie AA/AAA so no I'm not keen on using it for those, Li-ion doesn't seem to be a problem. I wish they would update this one though and fix a few things
@@MrBazReviews Just tried some AAs on mine for the first time and they got far too hot for me to be comfortable with using it. Gonna be looking for another charger. Is this not a problem with the D4?
@@industrialovenfan8098 This charger is OK for Li-ion but Ni-MH as you say and I noted the heat problem. D4 I have never seen cells get hot on that charger
would you recommend not to charge 21700s all the time at 1.5 amps? will it take life away from them? i have this charger and it always fast charges my 21700s.
For 21700 it's fine as it is for most 18650. Some 18650's ie lower drain I'd charge at 1amp, the high drain cells are fine at that speed. It won't effect their lifespan it's only when doing really fast charging (some can take 3-4amps) that will shorten their life. If you are vaping that discharges cells faster so that is why vapers tend to get through cells quicker.
I bought a new i4 today. Can i charge an AWT 18650 battery at 0.5A. How should I do it on this charger? Because as far as i know - lower the charging speed = excellent charging. Also is this a good charger?
It's an alright charger for Li-ion cells (not so much AA's or AAA's). One 18650 is default 1.5A charging, just insert another one to drop it to 0.75A. You can't manually pick the charging current. 0.75A is fine for any 18650

You only have fast charging for one slot as shown in the video, to reset just power it off. The i4 isn't a fast charger it just has the capability to charge one cell faster if you wish
What are you charging and how warm is it? It gets pretty warm in my experience using it. Not to the point it's dangerous though. The built in transformer generates most of the heat.

Hi the red indicates charging speed if there is an error all the LED's flash at the same time (3:57). If the red is on and one solid green and one flashing it should be charging the green LED's stay on to indicate charge status so 1 green a third charged the LED above it should flash until it reaches 70% ish then go solid etc etc. How long has the battery been in the charger?

Have you tried other batteries? Wondering if there is a problem with the charger doesn't sound right. Not sure if you have another charger to try on the Aspire battery I've not encountered this problem

Hey how do u know when the charges is done? I put 4 battery in to charge all the green light was blinking and all 4 green light stop blinking! Once the green light stop blinking does that mean the charges is done? Thanks
I put 4 batteries one is blinking 3 yellow leds plus 1 red light what does it mean its not reversed tho I tried putting it on another slot same thing the red light transfered specifically for one battery?
If they all flash at the same time it's an error (battery problem) if the red is on it indicates fast charging, normal operation should see the green LED's lighting up from bottom to top in sequence depending on charge state, red shows on the fast charge channel
Mr Baz Reviews ok so the 3 batteries are in normal charging state the fourth one all the lights are on including the red one but its all blinking,all 4 batteries are AA type..whats happening?
Cell must be defective if it's inserted correctly try another cell, clean contacts etc. Usually shows up with an over discharged battery that won't charge properly
@@checkeredflagfilms I think it's the transformer that generates the head it could do with more vents, a fan would help but shouldn't be needed (not as these charging speeds) It's not usually a problem for Li-ion, it is for smaller cells AA/AAA. I was hoping Nitecore would update this with a better ventilated unit, longer slots, bit faster charging speed nothing so far maybe they will eventually
@@MrBazReviews also, would have been cool to install a beeper to signal when the battery is topped off. I'd have been willing to pay extra for these 2 features.
@@checkeredflagfilms Some have them the Dragon and Sky chargers, but you can turn them off too it annoys some people. It's worth having for those that want it
Not really transformer is built into the charger, more ventilation will help, otherwise a newer design can sort it out if they will do that I've no idea
If there is an error they should all flash. If the cell is low then the first light will flash. For dead cells try the activation mode (hold C and V with the battery inserted)

Yes you don't have to adjust the settings it's only if you want to change voltage or use the sequential charging (ie higher charge rate then move to the next slot). If you just put one larger cell in (ie 18650) then it will default to 1.5amp charging, 2 it drops to 0.75 amp etc.
Depends I prefer the D4 the i4 isn't a bad choice if you need faster charging on Li-ion cells (ie one cell at 1.5 amps 2 cells it's the same as the D4 aka 0.75a). If you also charge Ni-MH I would go for the D4 as it's better at charging those cells.

Thank you very much. Still helpful in November 2018 :)
Serious review. Thank you Mister Baz.
Yeah maybe I'll lighten up a bit perhaps I got tired of the goofy videos/pranks etc on CZcams so went the other way a bit ;-) Thanks for the comment
good charger i've been using for 6months now no problem
Thank you for your time spent on this well done video. You have helped me make my choice on which charger to buy
I've been charging 3x 18650 Sony VTC5 2600mAh batteries and since I've gotten the charger it has gotten very hot while charging the batteries there has never been a point where I was able to run the charger with mind at peace without a fan blowing directly onto it for many hours, is this an issue with these chargers or is mine just broken?
I have this one, I wish I had known about that xtar vp4 dragon you reviewed, looks so much better.
The Dragon is good though costs quite a bit more. i4 is an affordable charger so the two are quite different. I think the D4 is now too old to really consider (also doesn't have the faster charging this one does on a single slot)
Mr Baz Reviews I was looking at their vc4 as well and it's around $20USD and looks to have a much better display than the i4 intellicharger.
I'll be doing an in depth video on the VC4 I have another one coming in so look out for that!
Mr Baz Reviews that I will do!
I just bought this today as my very old 4bay nitecore charger's figure 8 connector deteriorated (did a great job). Currently charging 4 older 18650 batteries and set them to sequentially fast charge. Let's see if they haven't reinvented the wheel 🤔
It's been out a while but it's an alright charger for Li-ion cells, I expect an update at some point
There seems to be a variation in the product because mine had smooth lugs on the negative sliding bracket which often would not make contact with the negative end of the batteries. One had to jiggle the battery a bit to get then to touch the bracket, but they often work loose during charging and you return to find that you battery is as dead as when you started.
They may have updated it since I looked at it certainly possible I'd expect a new model out next year possibly a few different ones.
Wharendid u buy it from

This video has recommended chargers I'm quite busy editing so can't answer more questions if it's on the list it's safe and will work great:

i use 1 years now still work
Good to hear
Coming from the I2.. I think the holding on this one is worse! it gets hotter and did the same test and am not too impressed. Might invest in a better charger as these rare sony batteries were hard to find genuine ones (not re-wrapped) so I would like to have them last as long as possible and the heating up is quite alarming. I do like that It does regular size rechargables
The raised contact points can mean cells can sometimes slip off (button top ones). I'm not sure if the design has changed since I looked at it, there is a bit of heat to get rid off perhaps a bit more case ventilation would have helped
i have the two slot one and the left side only gets to half while the right side goes to fully charged. im now looking for a better charger. bad part this is only a week old but bought it when i was out of town. thank you for your video.
Is it a real nitecore? You should have a warranty with it. Whilst the Ni-MH charging isn't great on this for Li-ion it's acceptable shouldn't half charge a bay
I was looking for a charger for my 18650/RCR123 batteries, and somewhere deep in my mind I heard a voice saying "find Mr Baz channel!" 😂
I guess that means I trust your reviews! 😉
(It's either that or I'm having a psychosis....? 🤔
🤷🏻♂️ Oh well! At least my flashlight is working! 🔦😊)
No problem if new ones come along I will have a look just not been any new Nitecore's for some time
Did u buy it ? I m looking for the same brand too but i heard it gets too hot when it s charging and also i found another brand golisi i4 ? Which is better
@@imuluer I bought it see other response depends what you charge
Excellent review video! Thank you!
Excellent information on the New i4 charger. My understanding is lithium batteries will last longer (more charge cycles) if charge is just shy of 4.2V as your video shows. The slight loss of power should not be noticeable. The NiMh batteries get quite hot in this charger. The heat can not be good for them so I will not allow overnight charging.
Yes that is true with regard charging cycles, not a bad thing to be a little under the 4.2v... the problem isn't the Li-ion charging it's the Ni-MH heat and termination. It's better than the new i2 which was under the 4.15V at times.
I'm not overly impressed with the Ni-MH side of things, few chargers heat batteries that much which isn't good for them (leaving aside the lower voltage readings which can vary a bit). It's not a fast charging rate, the Opus C3100 can charge Ni-MH at 1 amp across 4 cells and they remain pretty cool. Perhaps the design isn't allowing enough airflow to the transformer
I might place low value resistors or lamps to limit current to 50/100mA on each NiMh cell, thus lower cell temperatures. Thanks again.
i found out the 18650 batteries on mine dont get hot only the case gets hot on mine but maybe my AA batteries get a little warm .but i have got a fast charger for my AA and AAA batteries that get realy hot nowt like the nitecore
Hi the 18650's are a fair bit larger so don't have the same heat build up. AA's do even with all 4 bays in use, charge rate isn't high either. A lot of fast chargers do, but the Opus BTC3100 doesn't because it's got a fan. D4 doesn't have any obvious heat build up even at the same charging rate for AA's (ie all 4 in use 375mA). Case probably needs more ventilation slots
Hi Baz, Subsequent charges of NiMh cells don't show heat build up the first charge did on new cells that had been in storage over a year . Charge voltage is 1.405 so I'm happy with the charger. Voltage on the Li cells end up at 4.02 volts so again all is good as far as my low current use. Only thing is the "V" button seems to have zero effect. anyway thanks for your observations and good video. Bye. Jim
I have older version of i4 for some time and I figure out when I use 12V adapter it heat much less(about half less) than with standard plug when it need to use internal transformer, so it could be heat by transformer.
Yes that's what is causing the heat build up the internal transformer. I am hoping they update this and provide better ventilation for it
@@MrBazReviews Since I figure it out I'm using it only with 12V adapter. In my country I can get used 12V 1-2A adapter for 2€, it's easy to replace it when it broken, and I think charger would last longer because less heating.
I used very old Nitecore i4(maybe first version), and when it broken I get 2014 version and now I'm using it. When it get broken I will get 2016 version which you reviewed.
Charging Ni-Mh AA/AAA and 18650 batteries with it, good charger for it's price, I'm really sattisfied.
BTW. I'm also using Eneloop Ni-Mh AA and AAA batteries, they're fantastic.
@@MehemLED Maybe wait a bit I would expect a new version of this one to come out
@@MrBazReviews It could be. 2014, than 2016, and now after 3+ years no new version, so it's time to release new version. However I won't buy new as long this works. When this 2014 version get broken I will get newest available.
Excellent review.
Love the charger. Charging LG 4X 18650 3000mAh 3.7V. The first time i charged the batteries took some 18hrs. Now im just going to keep changing the charge settings to have a lower charge so that the units last me a little longer. Thanx for the review. B.T.W. where can i get a car adapter for this device, OEM of course?
If your Nimh are getting warm at low rate charge, those cells might high internal resistance
It happens with all cells, including the Eneloop so I think that's not likely the issue. I believe the problem is the design isn't great for getting rid of head (prob the built in transformer)
It's not a high charging rate either
When charging one single cell, is there a way to set the charging current lower than 1.5A manually? I wasn't able to figure it out by reading the manual.
The default charging speed is 750mA for larger cells up to two (18650/26650) you have to set it manually for lower tthan 1.5amps if using a single cell. See 3:25 for the charging speeds
my cell is a 18650, once I insert it into a slot when no other cell is charging, the 1.5A led turns on automatically, so that means it's charging at 1.5A right? How can I turn that off in order to charge it slower?
Press the C button when you insert the cell to change the current from 1.5 to normal which is 0.75. It's quite safe to charge a single 18650 at 1.5amps that's about as high as you can charge without having any detrimental effect on recharge cycles.
I see. Thank you very much for your help!
do not buy it if u want to recharge 21700 batteries .... they say them compatible, but the spot is too tight for 21700s
@M D. Huz with 18650s it is OK
I have several 21700s and not had any problem fitting them in and charging.
@@ndrinks5550 the ones given with the istick pico 100w(AVB 21700 4000mah)don't fit in it...so yea. when i wrote that comment i didnt try other 21700's yet... so i admit it is wrong to say 21700 don't fit in it...but is wrong even to say"every 21700 fit in it"...im not the only one got problems with this common combo
@@alb12e345 I wonder what manufacturer the battery that comes with the iStick Pico is once unwrapped. It sounds like for whatever reason it is isn't sticking to the 21700 size spec, either that or just a really thick or perhaps even double wrap is the only reason I can think of. I'm really paranoid about battery safety though, extra width would make me suspicious even though the battery probably works fine.
im charging 2 samsung tnr21700s right now with my i4 lol
I wish there was a button to turn off the leds at night. I miss my d4 with this feature. It’s a shame it died
I had hoped a new D4 would turn up but it hasn't so far
Thank you for this one.
No worries!
Hello, I just purchased one of these and the buttons don't do anything. I am now charging 4x AA NiMh batts.
They don't for Ni-MH there is nothing to change default is 0.5A charging. The only thing you can do with Ni-MH is battery activation with the charger holding both down at the same time enters that
Maybe it's just me, but @2:07 it seems like the slider has too much play. The top portion seems to move to the left quite a bit as you're pulling it down.
There is a bit of play, not that I've seen any problem when using it. I've seen better slider designs on some chargers don't think it's a major problem the new i2 wasn't nearly as smooth for the sliders.
i had the I2 and seemed LOT sturdier holding the batteries. I though this was my imagination. My I2 was great but fried it using it in the car on the 12v socket as I guess running the 14V was too much. If you want to use it in car make sure its 12V REGULATED as normally the few additional volts doesn't hurt most devices but these cannot tolerate it. 2 days using the new I4 and this was my biggest issue as it doesn't lock down as tight
Out of the blue mine has just stopped working completely not lights or anything, I've also tried different electric point's around the house and still nothing 😭😭😭😭😭
If it's in warranty it's worth sending back/claiming it now sure how old it is?
When i charge , i hear a voice "..click..click..." when light is dimming. Ia that okay?
I've noticed a slight clicking sound on all the Nitecore chargers, it's probably the transformer wouldn't worry about it
There seems to be something wrong with my Nitecore New i4. Yesterday when I inserted 2 batteries in slots 1 and 2 (L-to-R), the charging indicator LEDs started jumping up and down, but also the LEDs for slot 4 started flashing up/down, although there was no battery in slot 4. I don't understand these chargers and I was a bit spooked. Can you tell me what's wrong and if I should be worried?
Doesn't sound right to me, never seen that. Unplug it for a while and try again, if no luck I'd send it back
@@MrBazReviews that happend to me.. sometyimes if you drain the batts 100% the charger cant charge them you need to give the battery more power first
@@saloscontent Activation press and hold both buttons to start that. Li-ion shouldn't often discharge to that point, so check the cells are in good condition
@@MrBazReviews it was a couple of years ago. I have drained the battery lower then the charger could take up
I just picked one of these up and plugged it into my power strip and it flashes once but then doesn't respond to the batteries insertion.. it works in the wall outlet.. must have a problem with my power strip? Or there's a loose connection and I got lucky
I can't remote troubleshoot problems, but if it works on one outlet and not another, that would kinda say to me there is nothing wrong with the charger, and something wrong with one power source ;-D
solid review.
Thanks tried to make it as useful as possible!
Lovely review!
thanks glad you found it useful
Hello, I have a question : when I charge my 18650 with the I4 and then put them in the D4, the are never fully charge. Around 4.10 instead of 4.20. Is the something I should do ? Thanks.
D4 should charge up to 4.18 or 4.19 least the ones I've used and tested do. If it's not there are only 2 things the charger (ie try it with other cells) or the battery is worn out. Sometimes worn cells won't hit get up to a full charge I'm not sure how old it is or it's but I've seen it on other Li-ion cells that won't get up to full voltage
@@MrBazReviews Thanks for your answer. Actuality, my D4 works perfectly, I use it to test the charge of the batteries I have charged with the I4. The I4 only charges the batteries up to 4.10.
@@Alexis_Wajdenbaum Must be faulty then it should at least hit 4.15 or above. Most Nitecore chargers go to about 4.17V it's common to be a little under the 4.20V
Does anyone know the reason why a red light might stay on during the charging? Does it mean bad battery?
Try a different slot
Im having issues where it only charges on bay 2 and 4. When I power on the charger I can see all 4 bays light up. What could I do to make it work?
Don't know if it's under warranty try that, if not then it's obviously got a problem
i got this "New i4" charger and the buttons don't appear to do anything but interrupt the blinking on the LEDs.
Good idea to read the user guide, they do have a function it's shown in the video quite clearly
what happens if i charge a normal 18650 (max voltage 4.2) and it charges it up to 4.35?
Shortens the life span over charging nothing bad likely to happen, unprotected cells can vent (but need to be higher than that), protected ones have a circuit that prevents charging above 4.25V
@@MrBazReviews i charge mainly unprotected cells, thanks for the fast reply!
Hi quick question, does it have a auto cut off feature, already spoil 2 charger for my ecig, thanks alot for your reply... And nice review
Yes it auto stops charging when cells finished any decent LI-ion charger will stop
I guess I'm going with the xtar vc4 because the I-4 seems to have too many problems and overheats and I don't want no issues even though I rather had that because the LCD screen in real-time charging is what I want unfortunately You Can't Always Get What You Want so unless I want to pay top dollar I'll just settle for that
You are right!
Is it correct that it can only fast charge one high capacity battery at a time? Because I just tried adding 1 additional battery and setting both to fast charge by pressing C and holding C as you explained, then 2 more, so a total of 4 at a time, and then all 4 red LED's were on.
It can only fast charge 1 bay at a time, what happens is it will switch over to the next cells and faster charge that when it has finished the first one, and the next one and so on
I have noticed that I can't change the the 1.5 amp down on single 18650 charge. After charging 1 battery I get 500 hits. If I charge the same battery with another which drops the amps, I get 800 hits. This automatic 1.5 amp is unacceptable to me as I feel that it is killing my cells and I use single cell MODs. I can't find a way to tell it to charge at lower amp for single.
Hold the C button down to get out of the 1.5A charge rate - the red light shows up by default for one cell for 1.5A charging. 1.5A is unlikely to hurt any 18650 for cycles, most of those high drain cells can charge at up to 4A (that def will impact cycles). Only the high capacity ones say 3500mAh have a recommended charging speed of 1.0A (they can take more that's their best speed to preserve cycles), other ones can charge way faster
@@MrBazReviews Thank you for responding but with 1 cell the hold C button does nothing and I definitely notice a huge use difference. It may not be hurting the total life of the cell but it is hurting the single charge usability. I actually thought my cells were dying after using this for the first time, but they are fine if I charge 2 or more cells in it. It seems that C button only works for making 1 of multiple cells to charge at 1.5 amps. I guess I will need to buy a single 18650 charger or one that gives better user control over possible trickle charge.
Mine also undercharges, so it sits unused while I use,my Opus C3100! 👍
The Opus is a good charger I use mine all the time
Hello mate, I wanna buy this charger for 21700 batteries for my vaping devices, but I also have a second options with XTAR VC4SL USB charger, which one of this chargers is better for highly-rated 21700 batteries (more than 4000mAh on 3.6V at 40A)? Tnx a lot and greetings from the Serbia...

Wondering if I can get your opinion. I bought this unit couple of years ago. I hadn't used it a great deal but now it has a smell like burnt wiring and a little warm. The 1 light is blinking in all 4 batteries but it doesn't seem to be charging. Could it be the charger or maybe the batteries. The batteries are cool as well. Or do you think I should get another charger and batteries
Try batteries in different charger if possible, or try one activating the cell (hold both buttons to activate it)
is it possible to manually select the amps? asides from the 1.5 fast charge for single battery charging. I was told charging batteries at a slower rate would increase the life
Hi Garth you can manually set the charging for a cell such as a 18650 to 0.75A from 1.5A (which is the default). It doesn't have a "low" charging mode like the D4 though where you could set individually lower charging current per channel regardless of battery type. If you are using smaller cells such as AA/AAA's, 18350's etc then the default charging speed is 0.5A or 0.375 if using all 4 bays. Hope that helps a bit
How long should i expect it to take to charge four 18650 drained battery's? Should i adjust anything or just set it and forget it cause so far all i see is 4 flashing lights on the bottom...
Hi charging rate is 0.375a for four cells so it's going to take a while to charge all 4 bays with 18650's (depends on capacity around 7-9 hours). You can charge one cell at 1.5a that's about as fast as it goes or charge in sequence at 1.5 amps moving to the next slot. 2 slots can charge at the same time at a rate of 0.75a. It's not a fast charger for multiple cells ie 3/4 at the same time.

same problem
found out if you turn it on its right hand side it removes the heat better.. the
heat holes are not in the right place
Interesting I think really the case could do with a re-design as it's meant to lay flat. D4 doesn't pump heat anywhere near this level maybe a MKII will address the weaker points. That said it's working fine so far
@UPSIPO a small fan blowing on it will work wonders.
Getting a hot plastic smell from mine. I don't use it often, because I'm paranoid it's going to burst into flames. It should be fine, as my Samsung 25R 18650's are compatible.
I'd be surprised if there's a major issue like bursting into flames, there is heat build up - but the transformer is built into the unit hence it's likely to be warmer. Evidently they are covered via a worldwide insurance no idea if anyone has ever claimed off of it or how useful it is. My main grumble is heat on smaller cells Ni-MH, the Li-ion charging is reasonable hence I'd suggest the D4 for users with mixed cell types despite the slower speed for single battery charging
mine too im going to open it up and see if i can vent it better by cutting out some plastic
Im charging 3 18650 hohm life batteries as i type. There is solid green lights on bottom and blinking lights on second row. Does that mean its charging? Or is there something wrong?
Yes
Wow, mine is exactly the same, SUPER HOT! To the point that I stopped using it. Is it ok to use it like this, is it dangerous? I definitely CAN'T keep my finger on it HOT!
I think it's more a problem with Ni-MH cells ie AA/AAA so no I'm not keen on using it for those, Li-ion doesn't seem to be a problem. I wish they would update this one though and fix a few things
@@MrBazReviews Just tried some AAs on mine for the first time and they got far too hot for me to be comfortable with using it. Gonna be looking for another charger. Is this not a problem with the D4?

would you recommend not to charge 21700s all the time at 1.5 amps? will it take life away from them? i have this charger and it always fast charges my 21700s.
For 21700 it's fine as it is for most 18650. Some 18650's ie lower drain I'd charge at 1amp, the high drain cells are fine at that speed. It won't effect their lifespan it's only when doing really fast charging (some can take 3-4amps) that will shorten their life. If you are vaping that discharges cells faster so that is why vapers tend to get through cells quicker.
I bought a new i4 today. Can i charge an AWT 18650 battery at 0.5A. How should I do it on this charger? Because as far as i know - lower the charging speed = excellent charging.
Also is this a good charger?
It's an alright charger for Li-ion cells (not so much AA's or AAA's). One 18650 is default 1.5A charging, just insert another one to drop it to 0.75A. You can't manually pick the charging current. 0.75A is fine for any 18650

Hi the red indicates charging speed if there is an error all the LED's flash at the same time (3:57).

I have the nitecore i4, whenever I charge my battery the unit gets warm. Is this a usual occurrence?
As I say in the video it gets pretty warm
Hey how do u know when the charges is done? I put 4 battery in to charge all the green light was blinking and all 4 green light stop blinking! Once the green light stop blinking does that mean the charges is done? Thanks
Yes when the green LED's stop flashing charging is done
Mr Baz Reviews -thanks! Great videos give u a thumb up!
I put 4 batteries one is blinking 3 yellow leds plus 1 red light what does it mean its not reversed tho I tried putting it on another slot same thing the red light transfered specifically for one battery?
If they all flash at the same time it's an error (battery problem) if the red is on it indicates fast charging, normal operation should see the green LED's lighting up from bottom to top in sequence depending on charge state, red shows on the fast charge channel
Mr Baz Reviews ok so the 3 batteries are in normal charging state the fourth one all the lights are on including the red one but its all blinking,all 4 batteries are AA type..whats happening?
Cell must be defective if it's inserted correctly try another cell, clean contacts etc. Usually shows up with an over discharged battery that won't charge properly
Mr Baz Reviews oh no! This battery is expensive ,its immedion battery I have 8 of them,let me see what I can do...
Once the battery is fully charged does the charger shut off or somehow indicate that the battery is fully charged?
All the green LED's are lit, not flashing hence it's charged at that point
@@MrBazReviews thanks. I've got a 3000mah 18650 that's taking forever! plus, as you mention, this unit heats up. they should have put a fan on-board!
@@checkeredflagfilms I think it's the transformer that generates the head it could do with more vents, a fan would help but shouldn't be needed (not as these charging speeds)
It's not usually a problem for Li-ion, it is for smaller cells AA/AAA. I was hoping Nitecore would update this with a better ventilated unit, longer slots, bit faster charging speed nothing so far maybe they will eventually
@@MrBazReviews also, would have been cool to install a beeper to signal when the battery is topped off. I'd have been willing to pay extra for these 2 features.
@@checkeredflagfilms Some have them the Dragon and Sky chargers, but you can turn them off too it annoys some people. It's worth having for those that want it
Is the battery slots big enough to charge 4x 26650 at the same time?
Not enough space for 4 on this charger
Hi, anyone can shed some light on the V button? What purpose does changing volt serve?
Ah Voltage is for lithium cell
Exactly if you use the normal 3.7V Li-ion you don't have to touch the V button (ie voltage adjustment)
Mr Baz Reviews appreciate it. Thnx a lot
Can you help me? I put in flat batteries and the charger says they're full instantly, what should i do?
Are you sure they are flat? If so then the cells are defective
Definitely all flat they can't be faulty, I've got two 26650s and 10 18650s that all say they are full but they are not. Must be charger.
Same problem here and i have new batterys.. any help ?
Can u charge a regular reachable battery like Panasonic 1.2 volts
Ni-MH and Ni-CD cells just don't charge alkaline batteries as they can leak!
How can I rest my bitecore i4 because mine won’t turn on
Check the fuse/cable if no luck it's broken warranty time if you still have one
Need help I got LG hg2 3.7v 3000mah batteries it says they are imr but I don’t know how to charge them in this nitecore i4
Just drop them in positive terminal facing up, doesn't matter if cells are INR or IMR, ICR etc charges the same.
Mr Baz Reviews it just flashes the bottom light on 3 of them when they are in does that mean it’s charging lol
In short yes
mine got very hot to! can we do anything about this?
Not really transformer is built into the charger, more ventilation will help, otherwise a newer design can sort it out if they will do that I've no idea
I have this exact one. I am worried its making noises
It seems normal for NItecore chargers it's coil whine, shouldn't be a safety issue
dose the light just stay green if the batterie is dead
If there is an error they should all flash. If the cell is low then the first light will flash. For dead cells try the activation mode (hold C and V with the battery inserted)
So should we buy or not ?
For Li-ion it's fine for AA/AAA I think better options out there
can you do a review on the I8 no one as done anything about it
Hi I only have limited resources at the moment if I can get hold of one later on I might try to. Or if a supplier or Nitecore send one for review (unlikely)
I have the i8 in for testing but will need some time to do the review (working on SC4 right now)
good info video.
Thanks for the comment glad you found it useful
whata time charger 4 batteries?
Sounds like the D4 is the better product?
That's how I feel better charging termination, better for Ni-MH too cool temps. The UM4 is also quite good for a USB charger, the D4 is solid though not that fast for charging to some it matter, some it does not
I have this type, after 5 minute is take smell plastic and very heat
Not great see how it is after a few days
can you put 4 21700 batteries at the same time
No
Hey can u use a rechargeable (cr123a battery) for this nitecore i4? Thanks
Yes they will work just fine
Mr Baz Reviews -thanks
at what volt should i charge my samsung 30q at? i newly bought them
Leave at default it's 4.20V
@@MrBazReviews is charging the battery at 4.20v will have it charged to full capacity?
because I charged it initially at 3.75v and left it for 6hrs and still not fully charged even though both indicators have it at 100%
@@silentloud Maybe it's faulty, it should be near to 4.15V when charged, on this charger it's a bit under the 4.20V
@@MrBazReviews i set it up to 4.20v and its getting fully charged now. Tested 2 pairs and all is well. Thank you very much for replying and more power to your channel! Subbed!
@@silentloud No problem glad it worked out
would you choose this over NiteCore D4 or Xtar X4?
Not really it's OK for Li-ion, the other two are better all round at Ni-MH
@@MrBazReviews thanks but do you have other suggestion on overall best of what you have tested? Looking for a 4 bay charger. Confusing lots of brands out there. Liitokala, efest, nitecore, xstar, golisi.
Ive put it in the right way and the error thing still comes up what does that mean??
Means it's not charging do the activation if you want 3:06
If it doesn't work cells are faulty
Mr Baz Reviews ok, ive put the lithium battery in all of the slots and it keeps doing the error thing
Put the battery in and push/hold both C and V buttons that is the activation function. If it still isn't working it's a dud battery
Mr Baz Reviews press and hold both at the same time?
Yes as per the manual it explains it
Can i put 3 18650's in at the same time without adjusting any settings?
I Am afraid i will overcharge LG hg2s and Samsung 25r
+DarkDFlame so 3 hg2s at once and 3 25rs
Yes you don't have to adjust the settings it's only if you want to change voltage or use the sequential charging (ie higher charge rate then move to the next slot). If you just put one larger cell in (ie 18650) then it will default to 1.5amp charging, 2 it drops to 0.75 amp etc.
It won't overcharge the cells least in my testing it never did if anything it's slightly under charging them
Thank you! 😁
so shell i buy the New i4 or go for the D4?
Depends I prefer the D4 the i4 isn't a bad choice if you need faster charging on Li-ion cells (ie one cell at 1.5 amps 2 cells it's the same as the D4 aka 0.75a). If you also charge Ni-MH I would go for the D4 as it's better at charging those cells.
thank you for your help , i will go for the D4.
Does this charge 21700 batteries?
Unprotected ones yes (ie flat top)
What about the Recovery Mode? Thoughts?
It works shouldn't have to use it very often not with Li-ion cells I've seen more dead 0 volt Ni-MH ones, again not that common but can happen
Mr Baz Reviews Thanks for the quick response!
Can you charge 3 batteries at once?
You can charge 3 or 4 they just charge at a slower rate
Ok, i was thinking about getting one. =))
