eBay 9 MILLION mAh power bank teardown (with schematic)

Isn't it incredible how much battery technology has advanced. This power bank claims to be rated 9 million mAh and yet it fits in your hand. Eat your heart out Elon.
I'd like to correct one of the computations I made on the Kink Palculator. I was a mere three decimal places off, so I regret that a full charge of this power bank will only power your Tesla car for part of a day and not a year. But you can probably fit quite a lot of them in the glove compartment for long trips. It's also apparently twice the capacity of a Tesla Power Wall, but with the advantage of fitting conveniently in your pocket so you can charge it at Starbucks and steal all their power.
In reality this is just the evolution of rival Chinese sellers on eBay trying to beat each others inflated figures. Their justification is that you might achieve this total capacity with all the recharges over the life of the product. (You won't.)
It's worth adding another warning here. Even if these units do have solar panels, do NOT leave them in direct sunlight as it may overheat them and cause the lithium cell to fail dramatically.
Aside from not actually being a 9 million mAh power pack, there was an element of disappointment to find that the real cell size could have been at least twice as big.
The lithium cell test came in at just over 9,000,000 mAh at 9,000,005 which is pretty good... No not really.
1st cell charge cycle = 2358mAh
2nd cell charge cycle = 2410mAh
The chunk of steel that adds reassuring weight to the unit is 70g (2.5oz).

It must be a relatively old design... My wife got one somewhere here in the US 4 or 5 years ago that looked precisely like the one disassembled here... right down to the orange face. The "solar panel" on hers kept bugging me by looking so fake, so I torn it down a couple of years ago. First, it did have a bigger cell and no added weight. But I was surprised to find the "Sun" pads actually were soldered via wires to pads on the solar panel. I *still* thought the PV cells looked fake, so I took it outside with a voltmeter to measure whatever it would output. Nothing is what it output. Finally I peeled the front sticker from the solar panel to reveal that it *was* just a sticker on cheap PCB material.

I recently took apart a Chinese no name calculator from the 90's or something. It had a clock and a solar panel. The clock was a generic wrist watch module with a separate battery, but fair enough. The "solar panel" was a translucent plastic piece with no wires coming out of it. The strange thing was that it came with instructions on how to take apart the back panel and change the clock battery, but then it was easy to see that the solar panel was fake.

At 2:14 we see 2 charge indicator leds on, meaning 50% charge. You drained 4.500.000 mA in 14 seconds.

[@hockeyguy820]

I bought a solar charged power bank similar to this but a bit skinnier about 5 years ago. Back then it was falsely advertised as 300,000 mAh. The solar feature is really not feasible. Exactly as Clive stated, the lithium cells get extremely hot in good sunlight, and the charge current was at most a paltry 40 mA. And it doesn't take very strong light to wake up the power bank. For example indoors with the lights on, it wakes up and starts blinking the small LEDs to indicate charging. The problem is that there is so little current coming from the small solar panel indoors that having the power bank wake up actually draws more current from the lithium cells than is gained from the light. A power bank that wastes power much of the time is not a good idea, so I installed a small switch to keep the solar panel disconnected most of the time. At least my power bank had 2 wide and tall (but skinny) LiPo cells in it, which filled the entire case. But they were very cheap and wouldn't even charge my phone once (phone has 3000 mAh battery). I have since replaced those LiPo cells with 8 14500 (AA sized) Lithium Ion cells. It is now much more capable.

Orrrrrr just find a CAD file of something similar, modify it with some CAD program and 3D print a personalized version. 😅 👍

[@ecospider5]

This makes me want to remove the solar panel from the one I have to use on other projects. Mine is a real unit with 20,000 mah and it gives a couple amps out the usb-c port.

[@jameslmorehead]

The PCB for the LEDs could be one of the newish ceramic prepregs such as the SH260. It's meant to be used with an aluminum substrate or core, but can be used stand alone as a lower power thermal heat sink at a much lower production cost as it can be used in the same production methods and setups as most FR4 prepregs.

[@derekloudon8731]

It’s sad that you made a miscalculation because I was on the point of ordering 1000 so that I could hand them out to the old folks in our village to keep them warm during the winter and during power cuts. Anyone know of a supplier of USB powered 2KW fan heaters?

[@finger351]

That looks like an updated version of one of my power banks, but mine is only 900,000 mah (or 8000). Don't plug it into a laptop, I thought it had killed mine until I did a hard reset.

[@RobbertDIYprojects]

[@MARKE911]

A local solar panel company gave me a 20,000ma/h solar charger almost identical to this except the battery is massive behind it. I only know this cause what you said would happen did. I forgot about it and left it outside and the next day the battery pack puffed up and separated the case. I turned on the flashlight feature and the damn thing is still flashing. It has a single light and has those exact light features. It's been over 2 weeks solid now and I am curious how long it will continue to flash and it continues to charge up during the day. It has a 5 light led charge status and it's showing 4 of the 5 lights. It's been rained on and at or close to freezing temperatures for a couple of nights. I'd take it apart but I'm sure I'd get burned or injured from the battery somehow. I want to shove a metal bar through it completely but I have restrained myself as my wife would get mad.

I think they meant 9,000,000 µAh but even that seems "generous."

[@zoidsfan77]

I have a powerbank that appears identical to this one. It was a gift. I've never taken it apart, and I'm now curious if the cell is also deceptively small. I have not measured it's capacity but it seems about typical for a low cost unit around this size.

[@seannot-telling9806]

Clive have you thought about doing what Forrest Mims III and the book series of Engineer's Mini Notebook? Might be something worth doing if you have all the notebooks on hand.

[@bigclivedotcom]

His books were very good.

[@chrissutton3043]

Lmao i bought one similar to this off amazon back in 2017 that was advertised at 10,000 mAh. To be fair it did make a decent power bank, but the solar charge always seemed to be going and never getting above the 3rd indicator. I always wondered if it wasnt using most of the solar charge to power the indicator lights and just barely charging the battery. I think its still in the glove box of my car, ill have to look now. I always just used it as a standard power bank and never really had high hopes for the solar side.

[@dlewis9760]

Same here. I probably paid 10 bucks for mine. The solar was "Nice" and wasn't expecting much and that's exactly what I got, not much. I do think the 10,000 is legit though.

@@bigclivedotcom Good point, thanks ;)

[@TheInternetHelpdeskPlays]

Correction I'm afraid. It wouldn't take 625 days to charge. It would take 1875 days to charge, given it's over a year long and there are limited hours of sunlight per day, which average about 8 hours per day over the course of a year, the 625 has to be multiplied by 3.

[@DeaconTaylor]

thats 625 plugged in. he said he wasnt going to calculate the solar charging.

[@TheInternetHelpdeskPlays]

@@DeaconTaylor ahh, good point. I'm just salty because I got a similar one (without outlandish claims) a few years back. 20,000mah, which it was, and a solar panel. A 200mah solar panel and a warning not to leave out in the sun. Piece of crap

[@hugebartlett1884]

I have an identical model and I must admit I have never relied on it much. As you say it does weigh a lot. Two output points rated at one Amp MAX. Charge does not last long even out in the sunlight. You warn against that! The two lights hardly ever come on. I have found power banks more reliable. Excellent video.

[@ChrisKnipe]

The best thing about that 9MW battery, may be the case. Looks like a very nice and sturdy enclosure!

[@laustinspeiss]

The 9 Mega mAh capacity is the new Chinese version of the old IHF / Music Power / PMPO rating of audio amplifiers. Let’s just settle for good ‘ol RMS power ratings, so /maybe/ *5000mAh RMS, or 5Ah in real world numbers. I suppose the numbers are correct in Chinese, much in keeping with the words/language used in the flypaper user manuals. I just saw your battery test results, even my pissweak estimate was double their reality !

[@tactileslut]

I remember Chinese Watts from my first attempt at car audio. Similarly, when buying a tent you have to divide the occupant capacity by 4.5 to nine, maybe twelve if you're big.

[@laustinspeiss]

@@tactileslut LOL, I used to use a rule of thumb 6x in the 70s and 70s, but that’s a bit low nowadays !

[@Mister_Brown]

pmpo i'm pretty sure is calculated by feeding a max slew rate signal and extrapolating the peak if clipping didn't exist, should be called peak slew rate power bs all around still

Ha! Too Funny. Love it. 2.5 ounce weight could have been more battery for sure. A few years ago, for fun, I bought four 18650s claiming to be 9000 mAh. Amazing right? Turns out they're surprisingly light and have a capacity of about 650 mAh each. I mean I knew they were bogus but had no idea they were THAT bogus.

They could at least tried to make it 900 mAh so it would only be 'one order of magnitude' out.

I can confirm, I kept one of these (bought for holidays to hot countries) on a windowsill to keep it topped up. In the hot (UK) summer the battery expanded and pushed the case open. I snipped the battery out and gently took it to a refuse site. I told the guy there it had gone weird but he didn't care, just told me to put it in the pile with all the spent zinc-carbons.

thanks for sharing this. i have a similar battery and always wondered if it's as advertised. i tore it down and to noones surprise it was 8000mah instead of 20000mah as advertised

[@uxwbill]

For whatever it's worth, I have one of these with a battery that fills the entire case. I left it in the sun, situated where it couldn't cause any trouble if the battery did get angry, and amazingly, so far it hasn't. I wondered if the solar panel was even hooked up, but it does seem to charge. I've never tried to see if it would ever charge fully from the solar panel. I have another one with a total of four solar panels that unfold. That one will charge in about a day or two. With it, the panels being in sun actually cause the "charging animation" LEDs to start.

[@pistonbroke]

I have one of these, it packed up after two charge/discharge cycles. The solar panel is useless. I took it to bits and It does have a way bigger cell than the one in your video, nothing written on it to say what capacity it is though. The circuit board is slightly different too

[@teamidris]

The two pin power meter is clever. Whoever drew that up first must have been reet proud of themselves :o) and rightly so.

[@MrCool00236]

Just wanted to chime in, I got one that looks exactly the same, from a seller on ali. I decided to take it apart and have a look, maybe see if I could upgrade the battery. I was pleased to see a very large cell inside about 5mm thick and the full size of the cavity. I just re assembled it. My unit did cost a bit more than yours though.
