- A portable jump starter that fits in your pocket and actually works? Yes, it exists. I was skeptical at first but had trouble finding fault in this product. If you are looking for an emergency jump starter and portable USB charger this would be a good choice.
This product can be purchased at the link below.

I can't believe nobody's mentioned that it was obviously designed to look like a PMAG!
I'm glad I wasn't the only one who noticed this. that's the first think I thought of when I saw it in my subscriptions feed.
TheDiceAreLoaded Right. First thing I thought of was "30 round magazine" (PMAG brand).
+TheDiceAreLoaded Noticed that in the first few seconds. It has the ranger plate as well.
+TheDiceAreLoaded I at first glance thought they used one as the body but then he opened the box.
TheDiceAreLoaded i noticed that too. however there is an advantage to it. with a carabiner you van hang it if you had longer cables, so is doesn't fall in during starting.
I have one and have jump start my vehicle on many occasions with it is the best $50 I've ever spent. Couldn't imagine not having one in my vehicle
Nice video but it's a real shame you weren't able to test it out in a real world use scenario, like starting a car. I was expecting you to open up the battery pack and show us inside.
He did.......... Just an hour or so ago
Only seen a few of your videos but just want to say I love your style of providing extra info & commentary as you go. It's really valuable. I am a 'battery dork' as you termed it, I have an interest and curiosity about how things work, I know enough to be dangerous, but there's so much conflicting information around that it takes me forever to become confident in my understanding. It's wonderful to have someone more learned say out loud exactly what I had been concluding - i.e. don't charge these to full, store in the coolest part of the vehicle, recharge 2-3 times per year. Thanks so much it gives me great confidence I'm learning correctly. Best wishes whatever you're doing these days.
Please come back to CZcams. Your videos are sooooo good. I need more lol
Well done. I would be curious to see inside the green box, and listen to you review it's internals and tech.
"SOS" means "Help me --- I don't understand electrical stuff" or something like that. Liked your review!
Making those thin cables longer will soon result in excessive losses, rendering the product useless. As it is, they are long enough. I have a lead-acid jump-starter with cables only slightly longer.
While my lead-acid unit has other functions like an air compressor and 400W inverter, it is _larger_ than a car battery and just as heavy, though containing a much smaller battery of course. I would much prefer a small one like the review unit, and keep a dedicated 12V-powered compressor stored in addition. This would eliminate the requirement for monthly charging.
Fortunately, your previous video just gave me an idea. I'll plug the charger into the outlet on the front and turn on the inverter. Unlike yours it contains a lead-acid battery, so I'll leave it that way to keep it topped up (it is sealed so no worries about water depletion). Thanks, knurlgnar! Your videos are the best.
Last November I bought the Spirit brand of one of these for 70 the only thing different was it came with an octopus output cable to charge devices with. I never used it but it did save me four or five times starting thw xae on extremely cold days in the north east whether. I'm another one sold on the usefulness of these.
The blue connector is also widely used on RC applications I believe ;)
Good review, lots of information. I liked your test of it very much what I have come to expect from your videos. Also let me say thanks for being honest at the beginning and saying you got it for free, I've seen a few other youtubers do reviews on similar products and never mention where they come from.
***** I'm glad you mentioned the battery storage charge state. A lot of people assume that Li-Ion batteries have the same properties as Lead Acid batteries and they don't. Unless you are planning on using a Li-Ion battery right away you probably shouldn't charge it to 100% capacity since it degrades the battery a higher rate. My rule is to keep them between 40 and 80 percent since it maximizes their life cycle.
Laptop users seem to be the main ones that get caught out - Many can't figure out why their battery fails within 2 years, saying they only used the battery a few times and always kept their laptop plugged in, not realising what the constant 100% charge was doing to the battery. This also explains why UPS batteries are still lead acid.
+Seán Byrne True, but trying to keep your laptop battery at 70% constantly is not practical at all. You would be better off by unplugging the battery, but that would leave you unprotected on power outages, which most people wouldn't want.
+Hr Gwea I'm not familiar with Li-I or LiPo batteries. How would you know that you were at 70%? Could you charge it until you saw a certain voltage on the multimeter: if that works, what would the voltage be? If that's not the way to do it, can you tell me? Many thanks, B Bear
In general, my experience has been that that's right -- but cheaper units seem to be more likely to have a charge limiter on the lower end but not on the upper. Not all, but it's hard to tell what does and what doesn't.
I have one and let me tell you ,it does jump your car and it will jump it several times before u have to charge it!im ASE certified and I used it several times and it always jumps cars as advertised, it jumps cars better than my big jumper box. Just my 2 cents so no bad comments back I'm just stating how I used it!
They ripped off Magpul's PMAG design...
The alligator clamps have a rc type connector, and theres probably RC lipo inside, with high c-rate.Certanly 4S (4 series cells).
That's thing is producing about 1.6 horse power for a few seconds. Pretty impressive. Power dense.
It's crazy how such lightweight lithium ion batteries have such high power densities and curent capacities. Now we have the battery power to make phasers.
Didn't even watch the video, but awesome comment! 600 Amp jump starter sure is a lot.
$63 on Amazon on sale. I think not...... But like you said, if around $40, I would consider it!
could I use this to power any 12v circuit? like a small water pump or cctv?
Can you take it apart? I would like to see what cells they used to make the pack.
Thanks for the video.
I wish you made more videos... Or I knew more channels as good as yours. Do you have any recommenations on that matter?
Lagm an I actually don't subscribe to any channels similar to mine. Not sure why. Perhaps I get enough of that sort of thing at work and would rather rot my brain on the more typical CZcams content. :)
Interesting, I figured this would be a total piece of junk considering the size. I usually carry one of those lead acid jump starter/air compressor that's about the size of a car battery with me everywhere. When I had to use it once in 2009 on a 102 degree Texas day, it started a 5.4L F150 where the battery was at 11.2V(alternator died and had to change it roadside). That killed the lead acid battery and I changed it out and still use it to air up my tires, and would use it to jump again if I had to.
I was considering changing the lead acid over to LiFePO4 once it failed, but at that price point I might go with the one you reviewed. The only problem is where I am it can get pretty hot inside the cab and wonder how it would handle 130 degrees or higher.
sandman x It would perform excellent when 130F, but won't last long. Store it 70% charged or so and you might get a few more years out of it than storing it fully charged. Where lead acid is strong is in the storage energy per dollar. This lithium battery may be great for jumping a car or two, but it won't work well for powering an air compressor since it will quickly drain this tiny battery. This is part of the reason why car makers still use lead acid.
Clever test (using a dud battery in parallel). It looks like you had a good 23 seconds of current draw from your Bestek device--with a max of 91A!@~12.07V That's pretty impressive for such a small battery pack.
Do you know how many Li-poly cells are inside the Bestek device & what their performance specs are?
good review I wonder if Walmart would use them in the tle to jump start people in parking lot
The firm connector straight to the battery is called a EC5 connector. It is very commonly used amonst R/C and hobbie lipo batteries. You say in anothe rcomment your not sure its a true lithuim polymer battery, when its using such a connector that the 4 series Hobby/RC lipos use. So I'm pretty cerrtain there is a true lipo in there. Probably a R/C at that based off the connection to the "Magic black box."
umbrefawx Thanks for the info! The voltage suggests that it is Li-ion but I may be incorrect. It is a pouch style battery.
***** lithuim ion and lithuim polymer batteries use the same voltage for the most part. Pouch cells are lithuim polymer cells but even so, are still a type of lithuim ion. Lipos usually range from 3.7 to 3.8 volts on newer ones. Typically lithium ion batteries (like the 18650 cells in laptop batteries can be ethier/or 3.6 on older ones and 3.7 on newer higher discharge ones. So even so the batteries are different as far as chemistry, there is such a thing as a 3.7 typically lithium ion and a 3.7 volt lipo. So its not hard to get them confused. They even have newer lithium polymer (lipos) which are higher voltage. (think they are rated to 4.35 volts nominal and charge up to 5 volts.) which could be both a good and bad things as the newer 3.8 volt lipos charge to that 4.35 volt nominal range of these new lihv batteries as they called them, but as far as I know they are still in testing perpouses and require a totally different lithium ion battery charger.
umbrefawx But maybe it should be added that even so the difference between batteries as far as that marginal extra voltage. Both regular lithium ion batteries and lithium polymers (lipos) can be chagred the same way at the same voltages. (4.2 volts though for lifespan reasons as you mentioned in the video, its better to keep them around 4.1) only exception to this really is the newer 3.8volt ones that charge to 4.35 but even so with a slight loss and capacity can still be charged to 4.1-4.2 like the others with a small amount of capacity loss. (but still longer lifetime beneifits.)
+umbrefawx Great video! Thanks for sharing. Maxmade jump starter is indeed an ideal driving companion, very useful, portable and convenient. Visit bizarkdeal.blogspot.com/2015/12/maxmade-400a-peak-current-jump-starter.html , you'll find all the details. Happy New Year 2016. :-)
+knurlgnar24 I've seen these disassembled, they use a Hobby R/C style Lipo battery. The EC5 connector is a dead giveaway. Lipos are ideal for delivering massive amperages over a short period of time.
do you think Oklahoma walmarts sell those in okc
About time you made a new video..hope everything is ok..
Wow 6 years later and your back, where you ben, I miss the inverter hacks 😂😂
Hey, y u no posting more videos? I miss you awesome inverter videos.
Would it be possible to redo the test with the pack cold (put it in the freezer a couple of hrs ) to simulate a winter condition? I know from experience that the internal resistance of li-ion battery goes way up in cold temperature which would make this device useless if it sat in your trunk in winter.
Benzin O1 That's a good idea. Lithium batteries don't like temperatures below 0c which unfortunately is when you are most likely to need it.
+knurlgnar24 Agree. I live in the NE and my experience with car battery problems have almost always occurred when it's bitter cold. I would be interested to hear about a freezer test before purchasing one of these and falsely thinking I was prepared. If you do a freezer test would appreciate a heads up...and I'll keep an eye open for it.
73mΩ is wayyy too much for such application.
Cool the pack down to -10C to simulate it being stored in a trunk. Ri will go 10 times that and then I doubt it will give even 30 amps.
But thanks for review, it was interesting to see actual figures of these things. I played around with 10Ah headway cells some years ago when no such products existed yet.
elektrinis ....74 mOhm is indeed far to high. When set is cooled down to minus 10 degrees C. The resistance, however will drop by about 12%.
That's to say, the copper resistance will do so. With 10 gauge copper wire, all wire resistance is about 2 mOhm at room temp.most of the rest is resistance of pcb traces, solder (!!!) and internal resistance of the semiconductors. At an 80 Amp load, the heat loss of the wires is about 13 Watt, while the heat loss inside the switching box is about 500 Watts.....standard starter motors are made for 10 volt (in 12 volt cars) and are 1kWatt for passenger cars with 4 cyl. Motors. That require 1000/10= 100 Amps starting current. So these losses at start are; starter...1000 Watt, wires...20 Watts, switch box....700 Watts.....quite hot I may say....IMO the switch box is by far too light designed.....and unreliable.....greatings
Hey man, hows this unit holding up for ya after a few years ? Just picked up an almost identical version (bestek made a few cosmetic changes) for $30.
I un hook the battery in something and see if it will start and run on jump boxes to test them
new camera! looks great!
hey I have the whistler "jump&go" and it works well . I made a video starting my 6 cylinder suv on christmas . the regular battery was totally ruined but the tiny battery started my truck easily .
Maybe sometime you could do a video on super caps for starting cars..
I am looking for a jump start power bank for my RV, It has a 8.1 liter (496 cu inch) engine. Do you think this device will work for me?
Motel Prius no, I doubt it. I need to start a 3 l diesel, will see.
how do we know it could do 250v at 6v if we don't see it happen? it couldn't even reach 100 in either test.
because the battery was a good battefy
Can you please tell me what the operating temperature is? Im looking for a portable jump starter that can work in very cold weather. Thank you in advance for your time and help.
Only li polymer can truly crank out that kind of amperage typically. It would be nice to know if it is lipo or li-ion.
excellent review, I live in Québec, Canada. I'm looking for where to buy it. Thanks
There has been quite a few of these devices show up, it is good to know this one has decent protection. I seem to recall a device that used D cell batteries to perform the same task, although that was many years ago (decades)?
Craig Nehring The D cell ones would only be good for charging a dead battery and may be useful, but I wouldn't consider them a true jump starter.
***** D cell alkaline can kick out nearly 17 amps at 1.2volts that is 20 watts, 8 cells would produce over 130 amps at 9.6 volts under a short term load, of course they are not rechargeable but do have a very long shelf life.
The first "flashlights" were just that due to battery chemistry and configuration and could only deliver reasonable amounts of current for a very short time, they would recover in a short while to again deliver another burst of light. (9 lives indeed) We have come a long way!!
I'd like to see a hybrid super/ultra capacitor battery box. BTW, great video as always
Craig Nehring Thanks for the comment! I looked up D battery specs and the 17A would be about right for short circuit amperage. This means the maximum power output would be at about .75V and 8.5A. (At temps lower than 20c alkaline batteries perform very poorly.) You would need about two sets of 10 in parallel - 20 total - to be similar in performance to this jump starter at room temperature. But you're right, D batteries could work for this!
***** Wow, not sure what I was thinking when I wrote this comment... 8.5A per string of 10 batteries, so you'd need 10 strings of 10 in parallel for a total of 100 batteries. Still, D batteries could charge your dead battery over the course of a couple of minutes enough to start the car if that was the problem.
Are you still alive I love your videos why did you quit doing CZcams
Cool a new video! New camera too apparently!
I don't know much about these but I found myself here becaue I jump my truck with race drone batteries. My truck battery went the other nite so have had to jump the truck 3 times. I've noticed I pull 200 to 250mah every jump off of a 6s lipo pack. What's actually in this thing as far as cells?
Please show the internal of the battery pack. Would like to know the battery capacity and charging circuit.
The safety switch is a good idea. Diodes to prevent reverse current flow if the car starts is also a good idea. Storage life is good. So the last question is will it work? My answer would be probably for most 4 cylinder engines. Quite a few 6 cylinder engines will start with 100 amp kick. If you have to crank for an extended period it will probably fail. If the regular car battery is partially shorted out this gadget might not do it. So then you use your phone for a row call or jumper cables. I use an inverter and a small 120 v compressor to air up my tires. This thing will easily do the twenty amps I would need. So I could ditch the extension cord I carry but I like 100 feet of remote power and the big inverter I use is way more easy to carry than a generator. Those packs won't deliver the 4000 peak watts so I still have to get the car started for the big one.
So why are they not OEM fitted lighter/less bulk/smaller cables/save fuel not lugging a lump of lead around ???
The drawback for them is battery life for something like a car dealer or wrecker, but if you think about it, they don't cost that much more than a good set of jumper cables, requires less space, and you don't need to find someone willing to give you a jump.
I went through two of these from amazon before giving up. The first one would work fine until it sat for a few days and the power button would become unresponsive, and devices would not charge from the USB ports. Plugging it into the charger for a half second would be enough to wake it up and it would work fine for a while. The second unit the power button would not work at all but you could charge devices from it.
How many hours to charge the battery like 2 Hrs.....?
it seems to be a nicely made unit. but i would only use it for smaller cars with engines under 2000cc and are petrol and/or naturally aspirated. not keen on the battery getting hot especially the lithium type! but i would love to have it for camping for charging my phone! it would be better than the powerbanks
How come Bestek doesn't send one to me to review?
Short Circuit protection ? LOL It's operation is based solely on SHORT CIRCUITING that Battery.
The clamp popping off scared the poop out of me... 13:19 :-)
What is the capacity of the battery?
You think it would jump start a 6.2l v8 engine or at best a 5.4l v8?, thanks for the video, i was considering one of these last december 2014, they where all over lowes and home depot, i think it was whistler brand but they got recalled in Jan or feb of this year, are these the same polymer batteries they use on rc electric motors? thanks again
Fern W I don't believe this one has 'true' polymer batteries, just lithium ion with polymer separators like a standard laptop battery is my assumption. Either way I have little doubt that it will start a large displacement V8 without issue when it's fully charged and in good condition. I cannot speak for other similar brands.
+knurlgnar24 if it's anything like what I've seen before its probably a bunch of 18650 cells.
Peter Carlson 18650 cells can't produce near that sort of current (100A+). It will be a pouch style lithium like you find in RC models. 18650's usually output about 5-10A maximum.
abyssunderground Yup, it is the pouch style. In my previous comment I mentioned that it is 'laptop style' which is misleading since most laptops still use cylindrical batteries. But both are lithium-ion in most cases and not true polymer batteries. The pouch style has polymer separators and are often referred to as polymer batteries in advertizing.
Fern W I can't speak for this particular model, but I used a similar jump pack earlier today to jump a 5.7l V8 that wouldn't turn over. Got mine from the local NAPA dealer for $89 on sale. It's called the Blue Fuel, but you can also get it from Amazon as the Shumacher Red Fuel. Exact same box just different colors. The battery technology is Lithium Iron Phosphate, which is supposedly safer than regular Li-Ion or Li-Polymer.
A Pmag that jump starts my truck = awesome!
I bet it is LiPoly just from the application alone. I think these types of products always use LiPoly due to the inherently lower internal resistance. They just love dumping a ton of current. Which, of course, needs to be carefully managed and monitored.
Could u power a small 400watt inverter sololy of of that pack
HockeyStickLegs Yes, no problem but it won't last very long.
hi do you know how much they charge for an oil change at Wal-Mart
I got the Genius version of the many jumper packs, in my opinion it's actually extremely good very durable and powerful.
The thing I don't get is they can make jumper pack so small and so powerful why can't they do the same with car batteries??
they actually do make lithium ion car batteries, they are way more expensive than a lead acid battery though and they last about the same amount of time. when you need to shave the last 20 pounds of weight off of a prize winning racecar it is worth it, but who wants a 5,000$ car battery that needs replacement every 2-3 years?
redneckbryon Peter's right. I actually recorded a segment where I explained why car makers use lead acid when lithium is, on the surface, superior but removed it from the video for length.
I have to say, excellent review! Much more informative than most and thorough.
How many times can this power pack charge to capacity a typical laptop? Just curious, because I have had cheaper packs that can just charge a phone to full capacity and that was it. A laptop battery requires much more power, hence the question.Thanks in advance and keep up the great work!
+Tommaso Petrella i would get the easyjumper, it has a laptop output
great thanks guy
Maxamps makes 6500mAh with 150A C Rate, they'r quite expensive but they can handle lots of amps (6.5*150 = 975 Amps) ...
Excellent
On acid type jumper batteries longevity. Charge them once a month either 1st or last day of the month and be consistent. I get five years out of them.
THKS
So where do they get the 600A number from?
+paherbst524 dead short
+knurlgnar24 Would you trust it in a hot car trunk in the summer ?
I always wondered why there were arcs on batteries. 12v definately does not arc, ever.* I did not know about the inductance.
12v most definately does arc. As we speak I am drawing 2-3cm arcs from a 3v psu. my stick welder runs only about 30v when its closed circuit. as long as you ionize the air the heat will continue to ionize more air and allow you to maintain the arc, think a jacob's ladder.
I believe it's 600amps because of the highly explosive li-polymer battery. Li-polymer batteries have great amp ridge for there size but are highly dangerous when u charge them
not if you do it right. apple phones contain a lithium ion polymer battery too
HOW are they getting ~90 amps from that tiny little lithium polymer battery..??
I'm guessing there are 8x18650 cells inside based on voltage and size of the unit. These cells can usually support up to 10amps max draw. Given that this device only needs to be used at high amperage for a few moments they're safe pulling a few more amps out for just a few seconds. TL;DR - Magic.
Cold Cranking Amps (CCA) is not what was tested here, all he did was try and run a 2KW heater off an inverter for 30 seconds. A heater element is effectively a dead short, he was lucky not to make the thing explode! I doubt it will work again after that.
I believe I am first but i didn't comment right away :(, also i have a 3S boost pack like yours, so mines 12.6 volts and it starts my 5.7L hemi with no problems over and over again, I am not sure having a higher voltage helped in this booster pack (4 smaller cells with less Mah at 16 volts) over one like mine witch can use the same space to put 12.6v 3 cells with higher Mah capacity, great review and glad you put out another video for us! also any more inverter videos coming ? :)
fliping720 The higher voltage helps them get more amps out of a smaller battery when connected to a high drain load. Professional jump starter services often use 18V batteries for the same reason. That isn't to say a 12.6V battery is in any way inferior - it's just an engineering choice.
***** yea it seems that way, just looks kinda hard on the battery.
Please open up the starter pack and see what is inside
It looks like an AR mag.
hey how are you doing remember working with me
that looks like a banana plug for rc batteries, and most rc lipos can do 1-2 hundred amps continuous but only like 5 discharge cycles
11:04 what you said is false - continuity
i am looking for a way to drop 36 volt solar panels to 12 volts I have the ability to get 100 70 watt 36 solar panels for cheep but I have two 12 volt aims 5000 watt inverter would love not to have to buy a new inverter any suggestion's boss?
david wise Just buy a solar charge controller with MPPT function.
+Lau Chung Kyu wow thank you ill look into that I have ask a lot of people and got a lot of disinformation
+Lau Chung Kyu color me slow could you point me to one that would accept 36 and let the need voltage for a twelve volt system there are so many im lost

+david wise Don't buy this unit. This is a fake MPPT, you will spoil it with that high input voltage. Buy a higher price one.
if it has screws you open it ;)
+knurlgnar24 This is probably the first pack like this I have seen that looks like it was built to be halfway safe (I am sure others exist). The little black box looks to be the main thing that many of the other inexpensive Chinese booster packs lack. I am waiting for a unit like this that is 4-6 times larger and is truly capable of supplying 400-600 CCA at above 9 VDC (many modern cars won't start below 8.5VDC due to computer). It would be nice to see 4-6 gauge cables on this unit as well. Heck at 4-6 times the size and capacity it might even be able to replace many small car batteries completely.
kuhrd I thought modern cars required no more than 5V? It's not that I'm arguing with you but if you could link sources for the 8.5V number I would be interested in reading about it. Thanks.
Nice review. So if you read the print it says 600A not 600 Amps. Good marketing ploy making you think 600 Amps.....Hmmm!!
+Brian Schwarting dead short
why won't anyone make them with at least nr 6 wire?
Boy, I miss Knurlgnar's gems. Anyone know what happened to him. He hasn't posted for over 4 years. Hope he's ok
Well, I can say that I am still alive at least... BTW your comment reminded me that I had a video I forgot to release years ago on this jump start pack so it is posted now. Thanks for your comment and support Denis!
@@knurlgnar24 It's so great to hear from you and that you are doing well. I know I sound as if I am exaggerating, but I have received countless hours of pleasure watching and learning from you. Just ask my wife - I probably drove her crazy analyzing and discussing your videos
You created a whole new hobby for me -- off grid boondocking. Before running across your site, I was so far from knowing anything about electrical devices it was scary. You brought me up to speed quickly.
Denis
I dont mind you reviewing products that gets sent too you.
Just aslong as you stay the ***** we all know that delivers the conclution as it is.
"SOS function, not sure what that is" interesting
+Raul Galvez It's an old Morse code for Save Our Ship. It means "Help me". Of course no one today would have any idea what it meant.
My main issue with these 600 ..700 amp starters is the cable.. come on..my 15 dollar jump leads rated at 700 amps are 3 times thicker.
There's a bit of advertising 'lies' in there, but for jump starting you only need a few seconds of high amperage so thin leads like this can still do hundreds of amps without overheating. The issue with jumper cable thickness is more about voltage drop than cable heating. These jump packs have short cables so they can get by with thin wires.
@@knurlgnar24 I work for an independent test lab.. on testing these we found out that ..yes most will put out 700 amps....for between 10 and 20 milliseconds.. then the drop to 300 to 400 for 10 to 15 seconds then all the protection and alarms go off.
While this will start a petrol engine the diesel glow plugs eat up that valuable output.. so now you only have 3 to 6 seconds.. and it the main battery is dead.. its sucking some of that power.. so you often only have 3 seconds..
sorry but 6v to the starter motor is not an acceptable starting voltage, a lot of youtube test for these jump starters get 200A at these low voltage - Your car won't start on 6v! all that happens is things get hot. Minimum acceptable start voltage with battery under load is 8.5v (scraping the barrel minimum). Ideal minimum 9-9.5v (obviously higher the better). Remember you starter motor with the same output load is turning 50% faster at 9v then at 6v.
nice video but the audio is not much audible..
Ha ha ha. Clearly got leaned on, hence the update!
Looks just like a damn PMag.
Looks like a generic version of the NOCO Genius Boost GB30
Great review! I order one right now at amazon.ca 65$ Canadian all included.
just paid 42pounds for mine
looks like a P-mag
600amps! I'm sorry but I got my electrical engineering degree in 1987 so I may be old and the laws of physics have changed. 600amps at what voltage? The box references 12 volts and lower? Lets be honest this a glorified rechargeable lithium battery that Best Buy would sell, made in China and probably with inferior charging circuitry (designed to charge cell phones etc.) I would not connect that to a car battery unless you want to launch yourself into orbit.
Voltage does not equate into amperage or wattage. Your test using the battery charger is a cute deceptive way around not having to use the device on a real dead battery in a car or motorcycle. A disgraceful deception and potentially dangerous at the very least!
Peter M I assume it is 600A at 0V. This matches up well with my test showing about 100A at 12V on a 16V battery. True jump start capability, based on direct evidence of my test, will be in the 200A to 300A range which is sufficient to start most any vehicle. Car makers protect their vehicles against voltages as high as 24V since some people jump start vehicles with welders and other such sources so 16V is perfectly safe.
***** You are hawking a product, marketing it. The 600 amps at 0 volts = nothing, no such thing, no volts no amps. THIS IS SNAKE OIL plain and simple, you are not an electrical engineer because you would know it is unethical to pedal nonsense to the uninformed and basically make-up physics. I have PE and can assure any readers that this is pure mythical thinking. This type of device is readily available for little cost at any retail outlet without the car battery leads as they are ridiculous and will not work. Again this device is for charging cell phones and i pods, it doesn't appear to have a UL listing and lacks any form of acceptance by an agency for consumer safety. Your 100 amp test was not a test it was a collection DVMs, amp meters car battery charges wired like a birds nest that showed no real load test on a connected car battery. Peddling junk and old wine in new bottles is one thing, this is trying to deceive people and possibly cause severe harm to a user.
+Peter M bruh do you even know what you are talking about
Who is "bruh" or did you mean brother? I am not your brother. I do "even" know what I am talking about. Do you know what your are reading about in this 600amp portable car starter or battery starter? When you get PE (degree in electrical engineering) lets talk. I noticed you joined 9 hours ago, my post was 2 weeks ago, are you
KNURLGAR24s bruh?
+Peter M yo bruh ofc there is a few mV depending on where you measure, but we simple call it 0V or dead short. Ofc he is not going to try that as it would blow the device but this thing is working and capable of starting a car with a dead battery. Only fallback is that your starting cycle cannot last longer than 3-5s approx.
it has only about 100 AMP'S.
thats at a good battery voltage tho
