Sinkeu portable power station not turning on - Jak na to + styl
I loved the ending with the perpetual infinite charging conspiracy. Good stuff. I had a strong feeling about that button. I’ve seen quite a few of these types of repairs and even come across a couple myself where it’s either a simple manufacturing error or maybe from a drop in shipment. A loose connection, broken wire etc. The easy repairs are rewarding as well.
Thanks 👍🙂
Once again careful visual inspection proves to be so valuable. Well done.
Thanks again 👍
I've been watching lots of your videos recently, and really enjoying your content ...your humor very much reminds me of my dad ...he is also very much like you regarding tinkering with old electronics, and finding ways to repair them. Thanks for your uploads! I will keep watching :)
Thanks Daniel 👍
Was expecting the 'sine' output to be filthy, was not disappointed. Nice fix 👍
Thanks 😂😂👍
Nice one! No Parts Required. Ivan from Pine Hollow Auto Diagnostics would heartily approve!
Yes nice easy one (makes a change) 😂😂😂😂👍
Sometimes we deserve an easy fix. Glad this one was your easy fix! Until next time take care.
Thanks 👍🙂
Soon as he said "one moment please" just made me think of BigClive ! 🤣
Yes 😂😂I watch Big Clive too 🙂👍
@@BuyitFixitI thought you might ! 😊
And for those following at home, I bet he watches Dave at eevblog as well.
I won't take your money, the Venn diagram intersection is pretty much "yes, that's us".
Excellent job. It's a pitty it wasn't something more deserving of your talents.
Spot on. With that AC power button being squeezed from behind by the battery pack, it was blocking out any other button being pressed commands to the main controller meaning the unit wouldn't come on and/or the LED on the back wouldn't light.
It always amazes me the shite that comes off production lines. I have a lead acid battery car jumper pack, from a fairly reputable manufacturer, but no matter how long I'd let it charge for the fully charged indicator light would never go green. It also seemed a bit underpowered when jump starting a car.
I took it apart and found the nut that held the battery positive connection, and charge feed from the PCB, to the main on/off rotary switch, was loose, and the other side of the switch, where the jumper lead connected, was also loose. A quick tighten of the nuts, along with a few M10 nyloc nuts to double them up, and it was a totally different pack.
I'd say it left the factory with those nuts loose, so god knows how many of them were thrown out for being "crap", same here with the design or this power bank, unfortunately.
Thanks mate, yes quality control isn't great these days. Most things seem cheaply made and more "disposable". I mean look at the KitchenAid mixer I looked at, now that was QUALITY!
@@BuyitFixit yeah, my sister, who does a lot of baking, has one of those KitchenAid mixers and it's a tank.
No crappy surface mount electronics to go pop, and the way they designed the drive to have a sacrificial plastic/nylon gear is outstanding.
A true design classic, whoever designed it should have gotten a Nobel for design excellence. The fact that the design has been around for over 100 years and is still the same internals, speaks volumes.
The one I have doesn't have the nylon gear.. it's all metal! 😂😂😂
@ixit I just looked back on that video and, apologies, you're correct.
However they later replaced the small gear in the worm drive on the K5SS, at 13:26 in that video, with a sacrificial nylon/plastic gear, part number WPW10112253, so if the mixing head ever got jammed the plastic gear would get destroyed, as you mention in t text on your video, rather than the more expensive, non replaceable, gears.
If you still have that mixer it might be worth your while replacing that gear, especially if you use it to make any kind of heavy mixture, like dough for bread, or if you use the mincer attachments, etc.
Yes, still have the mixer, I think that's why the pins were slightly bent it must have been jammed at one point. I've not really used it for heavy dough or anything, I've used it a few times for making things like quiches or tiramisu 😂
No extra money spent for parts, nice. Just that magic touch of taking apart and putting back together did the trick. Case didn't look damaged from a fall, maybe the battery pack was installed crooked at the factory. Good fix!
Thanks Terry 👍Yes it could just have been thrown together at the factory. It wouldn't at all surprise me 😂😂😂
Case is tough, but that pack of batteries have more mass than you think just by looking at them so the 'dropped' scenario is the most likely to my mind.
Good deal, it was dropped only once and left out in the rain twice!
😂😂😂😂
Excellent find! These problems are some of the hardest to track down sometimes. Its also good that that button held down did not loop into some set-up or do a factory reset. 😂
Thanks mate 👍🙂
Nice fix Mick I can relate to the microprocessor symptoms, I had a call out to fix this tv one day the fault was remote not working, they had the faulty one and a brand new one in close vicinity to the tv, the old remote had a stuck down button which was cancelling out any other buttons pressed, and also stopping the replacement remote working lol 😊
Thanks Gary👍That was a bit of an odd one you had, great job on figuring it out!
Easy fix but don't you find it a little bit disappointing when it's something like that? There must be so many good things just thrown in the bin due to simple faults like that. Great video, thanks for sharing.
The problem is when buying stuff and you don't know what the problem is, it could literally be anything or nothing. I've bought quite a few items listed as faulty and I couldn't find a fault at all. Which is great for someone who wants the actual device, but not so great if you wanted to make a CZcams video on repairing it 😂
@@BuyitFixit Yes, exactly. I've buying faulty stuff for years, mainly highish value items that are very cheap because they don't work. It was good way to learn fault finding and electronics. I've never sold anything I've repaired, I give them to friends etc. I've given away about 10 repaired beats pills not all had the same faults. Your channel is great anyway. Glad I found you. 👍👍
Thanks 👍🙂
I hit the thumbs up button _then_ I watch the video😄
Because I know it's gonna be awesome
😂😂Thanks so much 👍🙂
Although it looks cheap and tacky, I was impressed by the build quality and labelled sockets and voltage indications provided etc. and @NOELTM you are correct visual inspection key to a quick repair in a lot of cases.:-)
I didn't think the build quality was too bad either. I've seen a lot worse in some products.
Love how you leave nothing out. Great troubleshooting skills, step by step.
Thanks 👍
Charging itself up is a great invention, Leonardo would have being amazed with this endless power module. 😁
Yes, free energy! 😂😂😂👍
@@BuyitFixit Sell it for 33 quid to your mate and borrow it when needed. Viola, free energy with 100 percent efficiency.
Yes, great idea 😂😂👍
I directly think the Problem was the stuck (permanently pushed) AC Pushbutton. I've seen many electronic Devices that are not able to recognize more than one Button to be pushed at the same time. Or strange things happen that are not normal.
On a computer keyboard, you can press several keys at the same time, but only a certain number of them. With normal keyboards, relatively few keys can be queried at the same time. If a Com-Speaker is connected to the Mainboard, it will beep when you push too many keys at the same Time. Gaming keyboards can query significantly more keys.
Yes, I think the code in the microcontroller might have been reading the whole I/O port and comparing that value to one of the "on key" so if two keys were pressed at the same time the value on the I/O port would not equal what it should. Something along the lines of 'if PORTB == 0x01 {PowerOn()};' where they perhaps should have been anding the value to get a specific bit instead something like 'if ((PORTB & 0x01) == 0x01) {PowerOn()};'. Thanks for the info on the keyboards 👍
I'd almost be tempted to build the full-size battery for it.
🙂👍
Actually seeing the first time you trying to push the AC button andi it was not clicking, made me think that this button being pushed all the time could be the problem .... as it turned out to be the issue 😉
Yes seems the microcontroller wouldn't respond to any other key presses as it thought the AC button was being pressed constantly.
Always love the bit where you say "looks like we got to take it apart then" like the beginning of an adventure 🙂This was a wiggly fix then, still interesting though. Strange how stuff often stops working after you have dropped it, must let something out like invisible magic smoke or something. Or ,maybe it is the noise when it hits something frightens it into not working?
WOW, just realised I have uncovered a new phenomenomenen, that would be why if you drop it on something soft it still works, cuz there is no noise to frighten it?
😂😂😂😂Cheers Chris👍
That was fun. Well worth the price these days. Sometimes you just need a little box like that to handle small things
Thanks JS, glad you liked it 👍🙂
Nice and easy repair. I don't know if you like working on tv's or not, but It would be a good video doing a tv repair. People where I live throw them out all the time, so it's easy to get something to work on. right now I'm working on an old Vizio piece of junk. The only thing I've been able to do to it so far is catch the power board on fire. oops! I did get that fixed though. now I'm retrofitting the florescent backlight tubes with LED lights. Thanks for another great video sir!
Thanks Ron 👍I used to repair TV's back in the day. I've done some CRT's and a plasma, and a few LCD's. The CRT's were either line output transformers / transistors mainly, and the plasma was the Y-SUS board (which I just replaced the board). I've fixed a few LCD's which seem to be mainly PSU capacitor related (standby light flashing).
@@BuyitFixit Yeah, they aren't to bad to work on. I'm just not used to working on something that has that small of components. I learned electronics at an early age, nearly 50 years ago, but i ended up being an electrician most of my life, so it's like I'm learning all over again. You definitely make it look easy though. I can say that I've learned more by watching your channel than I have the other channels on here. Thank you
Thanks Ron, so kind of you. I'm no expert, just a fellow tinkerer like yourself 🙂👍
As soon as you mentioned the AC button was not clicking I imediatly thought of soe arcade cabinets and gaming machines which will not continue booting until all keys are released. Bit like the "stuck key error. Press F1 to continue, F10 to enter setup" on PC's. The uC was confused.
Yes, exactly right 👍
Another good job Mick! Well done.. I wonder how long it would run by itself 🙂
Thanks Marc 👍I'm not so sure 😂😂
Nice touch at the end .
What a bargain by the way.
Cheers 👍😂😂
Magezi hi mina.
Thanks for sharing, I have the same model which is now charging slowly with its charger from 35w to 5w. I have seen that it has no BMS inside. If you have information, please, Share it, about how to fix charging to normal. I only charge with solar where it is faster now.
There is a BMS IC. The two wires I thought went to a thermistor seem to go to taps on the battery. I noticed they have 3.5 and 7.5V written on the connector. Perhaps it's a cell balancing issue?
Detective work, really nice to witness! Anyone knows what those two reversed RJ letters stand for on most circuit board? Appears at 8:40, second line. That question haunts me for month...
it looks like a handy little battery bank👍
Yes, I'm sure I can find some use for it. I think it's designed for camping mainly 👍
Person of many talents (still good diagnosis and a fix). Probably just out of warranty. You may need a different catchphrase (0:59), perhaps something like 'way'od about there, pet', ho, ho.
😂😂😂👍
nice 1 i know what to check if mine goes wrong
Thanks 👍
Excellent deductive investigations. Thanks for sharing.
Thanks Brian 👍
Mechanically it needs a complete redesign - it's just too flimsy considering it can output 230VAC. I'd even go so far as to say it's quite dangerous. Project for you - design a few 3D printed parts to make the thing more rugged!
Unfortunately I've not a lot of experience with 3D design, although I did try with a few programs I think the last one I tried was blender which seemed a little easier than the others I've had a go with.
I've taken a completely dead laptop apart and saw nothing obvious, reassembled it and it worked perfectly. It's goofy I know but poor initial assembly is a thing. It's ,portable so something shifted, Though charging itself form itself is an issue = dead battery now that's goofy
Light has the magical ability to repair almost anything.
nice find and fix, perhaps add some double sided tape to stop that piece coming out when its moved around?
Thanks 👍Good idea, although it did seem to be jammed in there pretty solid🙂
Most higher voltage power stations like about their capacity by adding up the capacity of all the cells. But of you put cells in series you don't get that extra capacity in amp-hours, it just boosts the voltage.
Plugging the charger into itself is like typing google into Google...... expecting to break the Internet..all was OK like the power bank lol😂 great content Barry from the Northeast SciVideos
Thanks Barry 👍
Google recursion. Geeky Easter egg. (Did you mean "recursion" in case they've removed it)
hi! hope you doing well . Thank you for another great video.
Hi, Thank you 👍 and yes thanks for asking 🙂
AC output is a 'squine' wave.
😂😂😂😂😂👍
"and it will run forever" - Nice, well done...
Thanks 👍😂😂
Take care you was with hand few times close to 220v output
Yes 😂😂wouldn't be the first time I've had a belt. Thanks 👍
Yes, if you take off your glasses and squint really hard, you might be able to confuse that with a sine wave.
😂😂😂👍
Would be good to see that 220v waveform with a load on it.
If it was anything like the sterling one, it was pretty much the same apart from the top and bottom horizontal lines of the "peaks" sloped towards the centre of the trace slightly (depending on the size of the load).
that will come in handy for all your test products good video
Thanks mate 👍
It’s been stored upside down that why the batteries have gone to a funny angle. If you look the battery only has support at the bottom and not the top.
Could well be the case 👍
You can hear that cheap reused ABS sewer pipe everytime you press that power button.
😂😂😂
Miracle worker
😂😂😂👍
Great video mate. Not much of a Power Ststion but still can be useful.
Thanks 👍Yes, I've got a few backup systems, but if we ever take the kids camping in the field or whatever at least it's something worth taking to charge a phone or even use as a light.
Nice one!, You sensed something wasn't right with that button early on and went straight back to after a nice tour of the components. Just an FYI, I clicked most of your affiliate links and they are all showing out of stock. Not sure if its because I am on a Aussie I.P address or they expire? Ill check back on your next video before I go shopping.
Thanks 👍I just checked them, it could be because I'm in the UK and they are UK links.
That was an odd one, great job.
Thanks 👍🙂
2:40 I bet it’s the stuck switch.
Yep 👍
I was hoping you’d plug a kettle in and make yourself a nice brew as a reward ;D
It wouldn't have enough power to boil a kettle. Most household versions are 2000W or so, and this only outputs 150W
thank you for the content sir. it helps a lot
You're very welcome, and thank you for the support 👍
Nice one again, thanks Mick 😀
Cheers Mike 👍
So there is no BMS cell balancing etc.? Looked like the only connection to the battery pack were positive and negative and a thermistor. That's a little worrying.
This is true! I didn't really notice that at the time! Unless the two wires what I thought were a thermistor are balancing wires? as they did go to a socket that had voltages written on.. so they could be.
Free energy! you're a genius!
😂😂😂😂
Nice easy fix
Thanks 👍
Well done
Thanks 👍
2:00 My guess (which is half the fun of this channel) is wrecked cells (obvs), caused by a bad BMS. Right. On with the video! 🤣
Damn! Wrong again! 🤣 Most instructional, thanks for posting these "Reviews"...😂👍
😂😂Thing is, it could literally be anything when you buy random stuff from eBay. It could have easily turned out to have been dropped in the sea or something like the power bank I recently looked at.
The button that wasn't clicking was the cause.
That was my thought too
Yup, I think so too. It was pressed, overriding the power button detection by the MCU. That’s my theory and I’m sticking with it! 😂
Nice fix either way.
(Edit: just finished watching. Never comment before end of video… 🫣)
Yes, totally correct 🙂👍
26:40 Infinite power here we go!
Yes 😂😂😂😂👍
easy fix
Yes, makes a change 🙂
Hi their is there a way to contact you at all, as I have a Vitron 24 charger that needs repairing gladly pay. Regards Richard
26:05 The power station charging itself seems funny, and then again it is funny, but you got lucky and dodged the bullet.
The power station has no grounding connected on the output socket, but the input of the 12V charger does have a grounding.
On this input there are safety capacitors between hot and earth, between neutral and earth, and between hot and neutral, these place around 50% of the mains voltage (very low current in µA range) on the earth pin. This "leakage voltage" cannot return to the power station, because it has no grounding at the output, but the grounding at the input of the 12V charger is almost 99% directly connected to the negative side of the 12V DC jack, so this leakage voltage enters through the input of the power station.
If TVS diodes are placed at the input of the power station, then there is no problem and they will clamp the excess voltage, but judging by the build quality of this power station, I doubt if there is any overvoltage protection at the input. A 5mm white power LED (2.8V) burns quite strongly with this leakage voltage and low current, but still fails after a few minutes, so other electronic components are also sensitive to this if this leakage voltage rides on top of the 12V input voltage.
Besides that, a nice video. Grtz
Thanks for that 👍
Im in the UK, I have a linx12x64 windows tablet with a faulty micro usb charging port. Would you be able to attempt to fix it? This is a serious request, please please please reply. Im posting here because i cant see any other way to contact you.
Is this ignorance on my part, but does that inductor shown at 9:34 sit a bit too close to the 12V input and output?
I like the way they added silicone to partially alleviate any issues, the inductor looks to be way off-centre from the silkscreen. Not the only potential design issue, of course. Respect to Mick, not trying to steal his thunder.
Yes, it does. It does look a bit worse on the video than the view I had of it though.
im guessing the ac button was jammed in because it wouldnt clock and shorting the turn on button..yeah i should have watched it first before comment...lol
Yes something along those lines 😂👍
Awesome, that has to take the prize for the worst sinewave ever, it's not even trying !! did the cells have anything written on them like manufacturer or capacity that you could see please ?.....cheers.
Thanks 👍😂😂😂 I forgot to look at the make of the cells. I think you can perhaps just see them in a couple parts of the video? I'd have to take it apart again to have a proper look.
No don't take it apart on my account LOL!! I'll check the vid !!@@BuyitFixit
I also have this power bank and it's having issues. When I plug the AC power adapter in it will charge at 35W for about 5 minutes and down to 1-2W and will stay like this until I unplug and re plug the AC charger. Any help on why this could be?
Hard to say, I would check the cells in the battery pack first to rule those out. I remember it does have a small black / red cable coming from the battery pack which I thought was a thermistor (temperature sensor) but it seems it's used for balancing or cell monitoring so it could be that some of the cells are charging to 4.2v (max) while some are only at 4.0v or similar which may give the symptoms you describe.
@@BuyitFixit @BuyitFixit I just opened it up to have a visual inspection. It seems the cables were squished together as the one in your video. I did separate them but unfortunately it's still having the same issue. I'm going to let it fully charge using the 1-2w to see if it balances the batteries out. Then do a full discharge.
Free Energy!!!! 😂😂
Indeed 😂😂😂👍
Title this "Free Energy from Portable Power Station" ... And watch that ad revenue pile up ;)
😂😂😂😂😂😂😂😂😂😂👍
Much of my repairs are from noticing something simple is not right.
Nice 👍
Hahaha, 10 of 10 idea for charging 12V from 230V part... "somebody" could find it useful...
Thanks 😂😂😂👍
mine is 150 watts
That doesn't even meet the standard for modified sine wave. 😂
😂😂😂👍
hahahh i was lookin at buying this hahaha,, seen it on flea bay.. i ended up buying 2 others and one ended up having lead inside rather than batterys scammer i ended up returning it to seller.!!
😂😂😂That's a bit sucky of the seller, glad hopefully you got a refund.
Shocking.🤣🤣🤣
😂😂😂😂
I Thought You Wer Gonna Use A VOM Meter To Check For Blown
Components? Cause If You Dont
Then you'll never know What Circuits Are Blown.
On the back of the battery pack there was 2 bits of 3M sticky tape that had not been peeled off so it sticks to the back of the case to stop it moving. You didn’t peel them off either 🤣.
I did notice those and assumed they were just being used as cushioning, although I suppose on the plus side it makes it easier to come apart than if it were stuck on 😂😂
@@BuyitFixit very true that 👍
The quality of the unit looks junk to me.
I didn't think the internals looked that bad, although the case was a bit plasticky.
Looks like a really cheap alibaba powerstation😅
You aren't wrong 😂😂😂👍
I don't think this device is worth £33 even if it worked perfectly.
Have you ever purchased brand new 18650 batteries? The batteries alone are at least £ 90 retail
@@Omri.Collects This is a used unit and the 18650's are used so I would price them at best $3 a piece, if they were name brand, which I'm sure these are not. My only point is I think that if the unit he bought was a working one then it would be a fair price, but for a broken one that might be unfixable it's not a good deal. Sinkeu isn't exactly a name brand either.
@@Omri.Collects
😂
El cheapo 18650s are 50p each online, op is right it ain't worth a toss.
Good vid anywayv👍
It's for camping, trips, mushroom festivals, burning man, etc...
Back when I was homeless, I paid a lot more for a lot less battery capacity, in the mid 2000s it was $70 for 20,000 mAh.
Your idea of cost vs worth is very skewed. The parts in that thing are worth a hell of a lot more . Perhaps come back to reality
Nice job, but you do not understand this device properly.
The battery pack in the middle of it is there to provide
for the needs of its conventional electronics only.
The real energy storage is powered by a piezoelectric element
that charges the energy storage when you press the right button repeatedly.
Just like a gas fire starter, as a piezoelectric element,
it can work if it clicks only. China does not want to disclose
this new kind of energy storage to the west. Therefore they
hide the real energy storage somewhere embedded inside the plasic of the cover.
Sorry to say, but Chinese engineers are so hideous these days
that you cannot trust your old and proven electronics instincts anymore.
😂😂😂😂👍
Battery is bad
Battery is fine, I guess you didn't watch before commenting 🙂
run forever lol 😂😂😂😂
Yes! FREE ENERGY FOREVER! 😂😂😂
😂😂😂😂😂😂
Are there any boundaries to the level of crap products the Chinese will produce and stick on eBay or Amazon. I bet most of this stuff isn’t CE certified. It may have the logo but nothing more
I guess not 😂😂😂😂
Humm?
