eBay 9 MILLION mAh power bank teardown (with schematic)
ฝัง
- เผยแพร่เมื่อ 3 ธ.ค. 2022
- 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).

The compass on the back is there for when the unit inevitably fails to charge your phone and leaves you stranded.
or so you know which direction to throw it when aiming for the bin.
@@howardosborne8647 We don't need any trash fires, thank you.
That's the moral compass of the seller. They weren't using it anyways.
@@rubiconnn
Those mini compasses are usually trash.
Completely plausible explanation, either that or they had a bunch of toy compasses to get rid of and instead of throwing them away, they just stuck them in these miraculous power banks.... making them even more awesome that what they were without it... It screams "Quality" and "Very Useful" if you have a compass attached to your product.
Who knew... some random Chinese company cracked fusion energy while we weren't looking and stuck it into a small plastic case to charge your phone.
Or wormhole generation, and they run some wires thru one to an alternate bizarro dimension where 'hundreds of AHr' 18650 lithium ion cells can actually exist.
A nation of geniuses,so they are.🤣🤣
better than fusion, they've tamed the vaccum energy and made a battery more portable than the Ancient's ZPM.
@@PainterVierax Or harvesting a bunch of dark matter and wrap it inside a polymer cells
Wonder which alien race technology they copy these from .
A friend of mine bought a "1,200mAh power bank that delivered maybe 250mAh. I opened it up and discovered that 3 of the 4 18650s inside were filled with sand. 🙂
that last one must've been mostly sand too, they're usually at least 1000 mAh on their own
I had one of these when I was young, that 3 Out of 5 was filled with sand xD
I love the way you said "The bastards!" as if you went to the bakery for your favorite bread and the baker tells you the people who left the bakery a minute ago took the last loaf.
😂😂😂
Really despairing that eBay and Amazon let the sellers get away with this crap, and they don't have a way of reporting them as fake before you buy. Even after, reporting would make little difference.
The one thing you can do is request a refund on those sites. If you have a good reputation as a buyer on the platform, you usually get a default judgement and the seller loses money. Anything else is pointless.
Works on both ebay and aliexpress at least, although it's been a while since I last had an issue.
I'm sure it's just a typo in the listing, someone blanked out for a moment and held the 0 key down too long
@@pauldzim There are too many identical listings for that to be true.
Worse than the power bank scammers are the flash drive scammers.
I was looking for one and saw a 2TB flashdrive for $39.95. Yeah, I'm sure, lol...
They have the same issue with flashlights and their Lumen ratings... they simply dont give a shit because they are a shitty company and should be avoided at all cost
This battery technology has been invented to power these 9 million Lumen flashlights, so it's totally legitimate.
Clive NEEDS to get one of those flashlights that BURN SHIT DOWN!
LOLOL 😃😂😂
along with the 10 billion volt tasers of course
You couldn't get 9 million milliamps from a wall socket even and that is enough current to cause fires, injure and even kill!!
@@charleshines8523 are you familiar with the word "Sarcasm"?
No its not they play games with words and specs to make it sound like what its not.
I had one of those for years, until a cell decided to swell. Was actually around 5000mah, did its job quite well. I knew before I bought it, it wasn't ever going to contain the 100,000mah it advertised, but it was still fairly reasonable.
SOMEtimes if you look in the actual specs, it'll tell you what the PV panel and actual battery capacity actually are. I had a couple that actually accepted a charge from light, but not really useful. they were definitely useful 5,000 packs, and people could ask questions about the solar panel and it was good for a story.
I've been laughing at these on fleabay for ages. Glad to see you ripping one apart.
I love your dedication to the absolutely comedic math on the 9,000,000 mAh capacity. Never change, Clive. Never change.
The problem is that this math is wrong. 9 000 000 mAh * 3.6V = 32 400 000 mWh so 32 000 Wh so 32kWh so 1/3 of large Tesla battery. Still complete BS but also shows that author does not understands units ...
@@mariuszdullak1399 I noticed the same thing immediately, but disagree with the conclusion you've jumped to. It's clear you didn't watch the video (or at least didn't pay attention if you did), because Señor Grande Clive, that Manx he, noticed and corrected the computational mistake at 7:25. There was no lack of understanding, rather a simple miscalculation.
@@ss-tx-rx2860 Yeah I did not watch the whole video. Maybe I should have marked my comment in ? I am full hand on with stupid "my friend" sellers who will put all the numbers you want anywhere. I own single 18650 powered flashlight which cost $5 (which I absolutely love BTW). On the flashlight itself it is stated 100 000 W!!! I also remember an app which when loading went to well over 999 999 % complete ... They are just crazy with number and not their meaning 😀
@@mariuszdullak1399 The correction is also mentioned in the video description, for those who don't have enough time to watch the whole video. He just made a small unit conversion mistake. Happens to everyone.
Still. The chinese who invented that label 9m is fools this guy to buy it🤣
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.
You know the Chins drip glee whenever they can sell crap to stupid Mericans
I bought to power banks that looked exactly the same but the later one had much smaller LiPo packs. You really roll the dice with purchases from China.
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.
lol glad i didnt find that to be the case with mine. at least mine does indicate that it sees light when it is in the sun light or has a flashlight aimed at it. but honestly the solar charging feature is a sale gimmick at best on these things but it you were using this as a survival tool i suppose you could get some use out of the led flashlights on it for a little while if you solar charged it all day or maybe you could charge it for a couple days then just bash it with a rock for a violent last resort fire starter. lol
@@rexsceleratorum1632I remember real solar powered calculators when I was a kid.
I think some/most of them did still have a battery for backup, but now they just have fake solar cell lol
I've been getting into the details of electronics through a few sources but your videos are so very in depth and you explain everything in a way that is easily digestible and even though I only know quite little compared to the level of your content, I find myself more and more interested in learning what all these bits and bobs do and why!
I always enjoy your teardowns and circuit explanations of all the items you have shared. Thank you Clive. I will share this video on my FB page in order to publicize this item as something to avoid, for gift-giving this Christmas!
Correct me if I'm wrong... at 2:00 we see 4 charge indicator leds on, meaning 100% charge (and a fifth led indicating that the solar panel is charging the battery).
At 2:14 we see 2 charge indicator leds on, meaning 50% charge. You drained 4.500.000 mA in 14 seconds.
Either your tester was measuring Teraamperes instead of Amperes, or you didn't charge the power bank for 2 years before using it, as suggested by the manufacturer...
Umm it's OBVIOUS that off camera, Clive had been testing it on his soon-to-be-release Time Travel device.
Clive has been waiting for some power source as powerful as the now, no longer available, Flux Capacitor to power his Time machine.
DUHHHH!
😅😂🤣👍👍
@@BlondieSL 1.21 Gigawatts achieved..
Pretty sure he left his load tester plugged into the mains and was backfeeding, thus supplying the entirety of north america power for those 14 seconds.
🤣😁 It's so true
Clive was of course using it to power his Tesla.
9,000,000 mAh is 9000Ah .. so 32.4 kilowatts ... still very impressive :-)
Until it explodes in your pocket.
@@bigclivedotcom I'd expect nothing less from my own personal power plant !
No no no, it's 32.4 millimegawatt hours. 😉
Kilowatt ..hour. but yeah better just have a look directly printed on the cell. Or measure it
I noticed it, that makes more sense. You could keep it in the glove box for a half charge on a Tesla in an emergency
The photocell connection being labeled SUN+ and SUN- made me laugh.
it's gonna need its own sun to charge that 9000 amp-hour battery :P
Funny to see you have one of these. I've had one of the same design that boasted 20,000mAh for a few years now. I knew the claim was bogus but was never intrigued enough to open it up to see by how much. After seeing yours adorned with a nice shiny brick, that was enough to send me looking! I was happy to find that the one I have contained no shiny precious metal bar, but a larger cell like you talked about rated at 4,000mAh. Not great but completely usable to my surprise! Thanks for the video!
I was given one of these today. Was asked to dispose of it safely as the (larger the one in your video) Li-Po cell inside it had puffed up so much the casing had been warped and had split open. Nice! It was at just over 2v so I've put it in bucket full of sand and left it discharging to 0v using a 3v lamp.
why not use just use a hammer?
No kidding!
My old beloved Samsung Note II phone had the original battery swell up like it was so very happy to see me... if ya gits me drift. LOL
It was so swollen that the back popped right off.
I'm happy that this didn't happen while I was using it or inside my pocket.
If it had, I could have been singing a different tune, mostly the really high notes.... LOL 😅😂🤣
SAND AND BAKING SODA, SAND AND BAKING SODA. BAKING SODA IS AN EXCELLENT FIRE RETARDANT

@@BlondieSL Same happened to my XIAOMI A1, though it didn't pop the back, but cracked the screen...
Wait, wait! Clive...
The 9 million mAh equals 9000 amp-hours, equals 9 kiloamp-hours times 4 volts equals approximately 36 kilowatt-hours. Tesla batteries are around 75 kWh so it *purportedly* is about a half a battery.
I think it's incumbent on the person who got ripped off to give a negative review or feedback so that others will be warned not to be taken advantage of. 😡👍
Thanks, Clive.
32kWh, since it's 3.6V not 4.
@@davidgriffin79
Like I said, "...equals *approximately* 36 kWh."
I picked up on that as well.
We still love you Clive...in spite of the calculation error...You will always be our favorite "take it to bits" guy!
I love the way you master speakin sarcasm so fluently. You Da Man, Clive !!!
I also had one of these...
Left it charging laying in front of the window and it finally signaled end-of-charge with a big bang 😆.
(also this seems a very fast way to open the case 😆)
They should pack them full of confetti at the factory, would be so great.
The automatic self-disassembly mode is a feature.
That was the end of life indication, which typically occurs before the end of charge point is reached.
That's how my cell phone opened up to let me replace its battery, though much slower and without the noise. Apple learned 20 years ago not to obsessively top off batteries, but Android is only now learning the same.
@@8bitwiz_ _"Apple learned 20 years ago not to obsessively top off batteries"_
Did Apple used to break into people houses and put their devices on charge whenever they could?
You do realise that Android isn't a manufacturer, right?
In my experience when you complain about a product on eBay the sellers appear contrite but always ask for pictures, even if a product has never arrived. Then the seller will tell you that they are sending out a replacement but never do. The whole purpose appears to be to string you along until the eBay return period has passed.
I've been asked to prove non delivery from an eBay vendor; how? A picture of empty carpet under my letter box 🤣
When the feedback period has expired without getting any refund, I buy the cheapest item in their store, just to be able to give negative feedback, and tell others what I think about the seller. Somehow they don't like that 🤣
Just ignore their "Please write us and don't start an ebay ticket" stuff and go straight for the "Request a refund" option on ebay. Unless the tracking number states delivered they will refund you without all the hassle.
@@Null--: Both vendor, and eBay refused to open a case of non delivery from Yodel, Yodel wouldnt help, I even asked them for a description of my front door, having some unusual door furniture. Paypal opened a case but demanded proof from Yodel, by that time I'd been led to a named e-mail address at Yodel who would respond, and a refund was paid
NB the name I had has been superceded by another look on social media
i had to send back laser engraver 100$ to japan costed 70$ soon as i submitted the shipping number i got my 100$ back -_-
2nd case- dvd arrived scratched as it poped of the spindle it bouced around all shipping came to me scratched they quickly refunded me $4 so it clogged up the return part for ebay.
had to then use paypal part of $ back coz ebay didnt garentee dvd cd to work
Thnx for your videos. They are always informative.
this channel, the sarcasm, the logic, im so glad i joined hahah.
0:30 Well, at this point, I guess they might as well rate the battery 32 MWh. :D
Also funny how you keep accidentally saying 9 mAh which, no matter what kind of battery they put in there, is guaranteed to be A LOT closer to it's actual capacity than the 9 kAh it's supposed to have.
That reminded me of those Chinese SLA powered spotlight torches from about twenty years ago, they often stated millions of candlepower from a 6V 25W halogen bulb..lol.
I had a friend with one who bragged endlessly about how powerful his was (despite only having a bigger reflector) badged with 1000000 candlepower. His bragging prompted me to print a very professional looking sticker for mine that stated 'One Billion Candlepower'... he was not impressed, and believing my superior numbers to of course be real, the challenge was on to 'out candlepower' me with something even bigger than a billion, but sadly he couldn't find anything. I never had the heart to tell him ALL the numbers were total BS, just like the multi thousand watt ghetto blasters from the 80's that were powered with a few measly D cells.. Chinese performance calculator: take the numbers and shift a few decimal places left then divide by four.
Reminds me of the 6k, no 12k, no 20k, no 30k! lumen headlights. That would melt your headlights and is brighter than most cinema projectors.
The sheer sarcasm oozing out in this video is fantastic!
I watched this and the one you did on the ozone 'thing'. I know very little about electronics but enough to be able to follow your explanations of how these things work as you do it very well !! So ... I learned some stuff but more importantly you had me laughing out loud more than once ... and I too am so disappointed that this unit was not 9,000,000 mah 🤣Great work Clive .. subscribed 👍
lads, I found this gentleman and his content by accident, I have been charmed and fascinated by his passion for electronics and "schematics"
but I understand nothing!
and very few times curiosity itches this hard, so I would like to ask, if you have any recommendation to learn about this from absolute zero
"one moment, please"... ☺️
You want to learn basic analogue electronics???
@@jimurrata6785 yeah, but don't know how to start
very few times in life I have felt this sort of curiosity, and really feel it would be a mistake to ignore this little itch I have discovered
@@jessemcallen8521 I started out in the early '70's with Forrest Mimms books and Heathkit _kits_ . I knew the resistor colour codes at six years old.
This was before the _idea_ of applied electronics would be found in your home (beyond a transistor radio or microwave oven)
I don't know where you'd start today. Surface mounted devices are another world compared to soldering through hole discreet components that have legs.
If you want to understand what components do (capacitors, transistors, diodes, resistors...) They are all just valves, gates, switches and tanks for electrons.
I'm sure you can find it on the web or get some of the old Mimms books. Find a mentor. Us geeks LOVE to ramble on about our special interests.
Just keep watching Clive. It takes a long time to trickle into your brain but you can pick up a lot
The best way to learn is to start playing with electronic stuff. You can get starter kits (suites) on eBay.
To get the full 9 million mAh, take a pair of wires that are about 93 million miles long, and connect them to the positive and negative terminals of the sun as shown on the board, pleease observe correct polarity
:D
does the compass show the magnetic force of the internal wring ?
Hi, is it north = positive or south?
Please answer quickly as it's getting quite warm...
If we could connect wires to the sun, one of us would short it out to see what happened.
@@bigclivedotcom Don't worry, it's quite safe, the sun has a thermal cut out.
Though resetting it is a bit of a pain - it involves an obelisk about 3km high orbiting Jupiter, guarded by a psychopathic computer.
Interesting fact: the computer used to be a HAL 9000, but the replacement was bought on ebay, and now it is a HAL 9,000,000mAH.
Use the moon as a fuse:)
@@gavinminion8515 Depends on the solar magnetic cycle. Thus even if you get it right today you can't leave it hooked up the same way until 2033.

If you're watching this video to the end?, I like you already 😎
I actually owned one of these, and it worked very well for me. I only used the solar panels for charging in the window. It was sold as one of those gift products in budget clothing stores last Christmas
I have that kind of power bank and thankfully I watched your earlier video on this solar charging scam where you showed that it actually drains the battery when exposed to light (the green LED). I never tried to charge it via the sun because I don't want it to overheat and I thought it was weak charge to start with. And I always set it aside with the solar panel facing the surface.
It could probably be done right if they designed a solar panel on a fold-out hinge, with a mirror covering the battery underneath instead. The mirror could not only reflect the sun away from the battery - if it defects it into the solar panel you get more power!
The green LED cannot drain the battery cell, as it is on the solar panel side of the diode. It can only waste energy from the solar panel.
I managed to put 4 of these panels in series and it certainly charged the battery in summer... but only in summer.
@@TechyBen I bought a 10W panel I can carry/strap on my backpack to charge the phone while I'm hiking
Nice. I was waiting for this one. Think I'll stick with my actual 200AH setup for now :-)
And if you think about it, a house is really just an industrial-size pocket, you keep all your things there. Even your 200AH pocket power bank.
Christ this is hilarious, so glad to see you about to hit a million subscribers
I bought a similar battery device several years ago at a Lidl's grocery store. I think it sold for around $12 and had no such ridiculous claims. For a back-up battery for your phone while you're traveling, it works quite well. The solar cell will recharge the battery, but it will take days. If your workplace has bright lights, you can just leave it on your desk, but it can be quickly recharged by way of the micro-USB port.
That was sooo scary when you were opening that up! With that much dc power, anything could have caused an arc to form and nothing could probley put it out till it burned its self up or got down to way under a million mah. I would have thought it would have to be oil filled or epoxy filled to keep it from self destucting! Lol.
I remember I was on my way home from Thailand in their airport with a tour group. I have a big powerbank (8x 18650 cell, you get the case and stuff your favorite 18650 in it) and is labeled as 20,000mah. I went through just fine. Someone else in our group had a much smaller power bank and it was stamped with a heavily inflated mah number and his got confiscated.
Hi Clive, thank you for very funny review. A great way to start Monday morning, I've got to go and clean up sprayed coffee now. :o)
The most interesting thing about that schematic is the way they use 2 outputs to drive these 4 leds. 👍
Some day, I would love to see Clive test something so beefy that it makes that tiny little fan spin on the USB load tester.
I still have a spare Apple USB-C charger (with neat super-springy fold-out pins) if you want it Clive. I'm afraid the bottle of gin that looks like a giant bottle of poppers is... no longer available.
My 68 watt phone charger will make it spin a little, off and on. But it takes a while before it moves. I am not sure how needed the fan is to be honest.
It won't ever spin in the first few seconds, since that heatsink wants a good heat-soak first before temperature reaches threshold. Thermal design on this little tester is really quite decent, quite effective.
But it'll spin up eventually even with very modest loads.
Our local biomass power station is 40 MW (it burns about tonne of straw a minute), a small solar park might be about 32 MW peak output. Truly remarkable technology 👏
I love the start-to-finish snark!
With such a huge battery, I would have expected to see the Explosive Containment Pie Dish on standby. :)
It would have required a blast wall if it was real.
@@bigclivedotcom explosive containment pie wall? My oven has 6 of those, it has protected me from many pie explosions.
For such raw power, I think Clive would have had to forgo the usual pie tin and step up to the Fray Bentos.
Great Video Clive, couldn't stop laughing. thank you!!!
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.
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.
That exact case is sold on ebay in many different packages by many different distributors and takes 3 - 18650s or one much larger flat cell. I bought a 10 pack of kits for my friends and family. They are decent chargers. The solar charger actually works rather well considering what it is.
Oh the kit comes without cells, so you can put your own in? That's a good way of doing it.
Tho they can still scam you with an unusably low power solar cell.
Oh? That's got me curious, was there a particular name for that kit? Also, how much did that 10 pack cost?
I kind of like the shape and think it might make for an interesting project case.
Someone dropped a drill at work and broke the chuck. When we got a new one it used a different kind of battery so I saved the old drill's battery and took the 18650 cells out of it and put them in a case like that to turn it into a cheap power bank. I have a good 20000Mah power cell already that I use to charge my electronics when power goes out and I use this cheap one with USB lights. I don't exactly trust the charging circuits in the cheap one with expensive electronics but I have no problem plugging USB lights in them.
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.
😅 👍
You might get 9M mAh if you can fission the lithium to helium.
I got scammed buying one these few years ago, good to see you doing a video on it now
I needed that laugh this morning. Thanks Clive....😂
Haha. Awesome! 😉 So, at what capacity did the cell test? Couldnt find it in the doobelydoo. ☺️
It's still discharging. The load isn't high.
Haha! Laughable. 2500mAh! :D :D
Ah, a CuriousMarc fan, I see.
Finally, the power bank to power your flux capacitor!
I have no idea what is going on but I love you man
It needed the optional Flux Capacitor module add-on in order to achieve its full potential. Thanks, Big Clive!!
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.
It's 32 Kilowatthour ( energy) and not megawatt (power) . So about the capacity of a small electric car.
I am very disappointed Clive☹️
This is why you should buy seven. One for each day of the week to keep your car running.
@@bigclivedotcom Good point, thanks ;)
Nice little powerbank there. I have the Nitecore pb on order to check it out. I'm coming for your screwdriver set, they look promising.
It has a compass in the stock, but does it also have the thing that tells time?
That'll put your eye out
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.
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.
This channel satisfies my lifelong need to disassemble things, to see how they work...
Isn't that silvery coloured rectangular block really Adamantium?
More testing please?
You can buy the impossible, but it never gets delivered.
Great teardown and video.
Thanks for sharing
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.
Throw it in a bucket of sand
@O. M. thank you,
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?
I had one of these (and lost it), and I've always wondered about the solar panels, thanks!!!
The outrageous capacity claims are alike to the crazy Lumen levels on Alibaba torches. Some back of the envelope calculations revealed that one LED torch had the same output as the Sun!
This leads me to an infinate power proposal: point the torch at the solar panel on the powerbank while the powerbank charges the torch! Use the excess power to run your house and electric vehicle.
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.
I think they meant 9,000,000 µAh but even that seems "generous."
I lol'd so hard to the first minute, Clive you are comedy gold how you describe things.
The best thing about that 9MW battery, may be the case. Looks like a very nice and sturdy enclosure!
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 got some of those lightweight 18650's , some kind of "TrustFire" brand or something. Inside they were a 14500 and some sand. Nice.
@@GannDolph Wow.
@@Frankhe78 Then it could have been a typo. LOL
@@GannDolph I remember seeing that "Trust Fire" brand. LOL Rubbish found on the likes of Ebay off shoots. Gosh, I forget the site.
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 !
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.
@@tactileslut LOL, I used to use a rule of thumb 6x in the 70s and 70s, but that’s a bit low nowadays !
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
Interesting idea to use RMS to measure DC 😁
@@bennylloyd-willner9667 Haha ! Just a point of non-comparison !
As meaningful as 9000MWh 🤡
I was hoping for a schematic of that weight. I might have understood it 🤣🤣 That was pretty funny 👍👍😁😁
I think you should return it in bits with a SCHEMATIC. 🤣🤣🤣🤣
Classic, love the line this is where it just bursts into flames.
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.
thats 625 plugged in. he said he wasnt going to calculate the solar charging.
@@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
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. [EDIT: typo fixed but I'm not going to try to pretend I haven't disgraced myself]
i do care that you have a typo, "he didn't care" ;-)
Oh, it wasn't defective, it just has to expand to encompass all those amp-hours.
@@jyvben1520 OMG, what have I done ? You've triggered the Mitchell & Webb "grammer nazi" response. I'd blame auto-correct but YT doesn't do that.
@@transientaardvark6231 grammer really ?
@@jyvben1520 Its what the sketch is called, and its available rite hear on the TH-cam "That Mitchell and Webb Look - Grammar Nazi"
Great powerbank. But I want the pink calculator more! 😍
I've had one of these for about 6 months, it's been brilliant.
9 million? That sounds dangerous. lol
If it failed in your pocket it would be exciting. Pretty much a Tesla crash in your pocket.
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.
His books were very good.
I truly aspire to achieve your level of casual sarcasm one day...
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.
cheers for taking yours to bit! i'm tempted to take mine apart when it craps out to see if it contains a metal bar for weight, but it has been useful for 5 or so years now. it has a cigarette lighter coil which comes in handy when it's really cold out, a light when needed, and no useless compass. either the solar does its' job by trickle charging or the battery holds a lengthy charge. i'd say two or three times a year it gets to one dot and i do have to charge it, but it takes awhile through the micro usb port. the two usb outputs are probably similar to this model, if i attempt to charge a cellphone and an ipad, one will cut out, so i only use it for one device. i also tried two different usb bendable mini fans and while one works continuously, the other just goes on and off. anyways, an upgrade is on the horizon with usb-c, wireless/qi charging, and millions of mAhs capacity!!!
I'm in possession of similar device and it works well. Use it as rescue power bank. I work 12 hours a day with heavy smartphone use and was saved many times after watching game for many hours. Never had to charge it. Just keep it on the window sill and always got ready for use.
I can see so much potential in that device .... ahahah .... still laughing hard 🥳. Thank You mate ! Have a nice day :)
Oh wow Clive!!! A dream come true, with this wonder-battery you discovered we can at last electrically power passenger planes for intercontinental flights! I am truly gobsmacked and humbled by this incredible progress in technology.
Very nice intro - I love your humor :-)
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.
Haven't laughed this much for some time. Great video.
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
i love how serious hes speaking about this ridiculous powerbank
Literally was looking at one of these with the case blown apart with puffed up pouches last night! Although the pouches were full size so must have got the high quality one, bonus... (until it popped) Apparently the plan was to charge it on the car dash - in the early Oz summer sun... Lesson learned one hopes.
Hahahaha nice calculation 💪 sometimes I'm laughing my ass off with the stated China specifications.
Oh Sir Clive, you have made my day whilst full of flu. Your kink palculator cheered me up as it does always. It’s a units of measure error or just a typo or rubbish.I once said said to someone I knew had a weight of 5 kg rather than 5 stone. Oh how we laughed.xxxx
Thank you Big Clive
Oh great I was just ordering one until you said it wasn’t 9m MA, you really got me on this one Clive 🤪
The metal chunk is a heat sink for the battery obviously 🙄
Gee whiz, at five volts, that's 162 megajoules. When I was doing pulsed power research and building railguns in my lab, I had a HV, fast-pulse cap bank that stored only 18 kilojoules and it weighed - literally - 1,500 lbs.
I had a party guest - FOAF - who works with battery chemistry at the Nat'l Renewable Energy Lab out here. He quipped that the difficulty battery researchers have been facing (for decades) is NOT achieving higher energy density than the current SOTA - that's easy. The challenge is ensuring that all the stored energy can't possibly - or at least not easily - come out all at once, really fast. (boom)
I'm old enough to remember when the whole "overloaded phaser" seemed kinda dumb, cuz it was apparently EM energy storage and not chemical, so in the 70s it seemed silly.
Now there are Li-ion cells that actually do store as much energy as my 18kJ cap bank and I am grateful indeed that they can't deliver it in a millisecond... we don't need to all be walking about with hand grenades in our pockets.
Just for fun, 162 MJ is roughly the energy contained in 1/4 kg of TNT.
Great Christmas gift!
Amazon sent me a free review unit one of those from a different seller, claimed 20,000 mah lol. Metal weight inside, somewhat slow charge, and solar panel uselessness aside, it was pretty nice to have around while camping.
