Ainope 10 000 mAh powerbank teardown
Вставка
- Опубліковано 18 жов 2024
- Today, let's take a look at and inside of a 10000mAh power bank (Vanguard-X1) made by Ainope, which was donated to me. It has 2 USB outputs (2.1A and 1A) and 2 different charging inputs. It also has a nice LED display indicating the state of charge. It contains a Li-Pol battery pack rated 10 000 mAh. Let's test it and see how does it work.

This was very insightful never realised how impactful trash cables can be
You (typically) get what you pay for. If it's cheap, it's probably cheaply made. It may "get the job done", but the performance will suck and/or it will have low durability. I know a guy who needs durable products due to how he is. He spent a bit of money on charging cables and tends to get the cheapo ones and they rarely last a month. Something on them will break. I tend to get proper cables and I almost never have to replace them. I still have some cables from a few years ago.
You can tell this Chinese company was VERY confident about their product or they wouldn't have sent you one to test. It does seem well designed, too! Glad you're making videos again, we missed you!
They could have added a protective? layer to the batteries, but it looks nice
36:42 Oh please do! that would be very interesting and fun to watch!
Very good teardown
For charging your android phone, if you have root, there is an app called "battery charge limit". It let's you set the maximum SOC when it will stop charging and also a lower bound when it restarts the charging. Love your videos.
Use plastic cards to separate batteries. I used it to tear down a laptop battery.
I also soak the batteries+plastic+glue in clean engine oil. Makes a mess but helps prevent the sticky glue from reattaching itself to the battery when you get a corner pried off.

How about just using a hunting know, instead use some cheap phone opening tools like this:

Scotch tape put on the terminals is enough
Thanks for interesting teardown. Respect to Ainope for honest declaration of capacity! I will make a note of that supplier.
Ah... At least you found something in China product which not in fake rating.
Nice explained & tear down..
I always wait for your video...
Good job... Bro...!
Thank you for donating this backup battery, now I’m gonna see what’s wrong with it!
Liked the fact that you showed the manual for those who want to know more about the product
I got one of these and I'm very happy with it. It will charge my Samsung tablet (7300 mAh) and the auxillary speaker simultaneously.
If I needed a power bank I'd buy this one just because of the very honest label. Listing Wh and mAh at 5 Volts after losses is how all power banks should be labeled.
that was the most comprehensiveness test and review of a battery bank I have ever seen....If I was in the market to buy one I would probably purchase that one..lol
Indeed most people do not read the manual.
The quality is what you pay for.
I love Your cat.
That other input is a USB type C connector, that allows charging at 3 Amps instead of the 2,5 amps via micro-usb
Can you test your silvercrest power supply? I belive that lidl sells good quality items, with corect specification.
LIDL POWER SUPPLY LULW
@oH well,lord! I do not understand, what you said.
it doesn't look any good for lidl stuff here

When you said the video is already very long I was very surprised that i had been watching it for 35 minutes. That's what happens when something is actually interesting.
Nice prying tool....bigger than the device....Great video and an awesome cat.
I have the updated Vanguard-X1 now with QuickCharge/PowerDelivery. They have kept all the good properties and just added QuickCharge to it .. very nice. A simple way to test the capacity from the outside is to charge it using 5V through a meter. Almost all powerbanks use a linear regulator in this mode. so the charged Wh may be higher but the mAh will be directly readable on the USB tester. :)
Outstanding video!
That electronic system looks like a very good battery charger--wise move keeping it for future use!
Thanks for sharing your knowledge & skills!
The white glue is in the powerbank as a fuse, so that people can not disassemble it and also the batteries do not move in a box of powerbank.
I love your videos, Mr. Diode!!!
-I would say the 6-pin chip is to get a higher charging current for Apple devices EDIT it's probably a DCP charge current negotiation chip that works for all devices.
-The 16 LEDs inside the display are controlled by a method called "Charlieplexing". It's a very clever technique that allows saving numerous pins on both the display and the microcontroller and thus saving a lot of space, at the expense of a more complex software.
9:58 That's probably because the cable doesn't have data lines. Most devices require communication with the charger in order to charge with more than 500mA or to charge at all.
actually I think that the problem with you chinese cable is that it doesn't have data cables so it charges slowly.
When I force my one to run at 2.1 amps it gets really hot.
I have an emergency power pack for jump starting cars and it has a power meter that acts just like this one.
It overestimates and it also does the catch-up thing if you turn it on after a long discharge.
I use it to power a variable pressure inflatable cushion for a wheelchair.
nice
✔️✔️✔️
hope China guys learn from your video
Problem is they can't understand him. xD
Glad to see it can meet its rated capacity but manufacturers really need to stop gluing their stuff together in order to make it harder to open.
There went my OCD 😂😂😂😂 and the little sticker
Ikr
Yet what happens to your OCD when your display gets a scratch on it?
That's why most people leave the PROTECTIVE sticker on there... to protect it LOL
😡😡😡talk about it...
@@johncoops6897 It protects during manufacture and shipping, it’s shit for actual use, both for touch and for optical quality.
I do exactly the same thing with the protective film. I always leave it on.
I've got the original/first Samsung Galaxy Tab & it still has the protective film on it all these years later.
Always entertaining and you can learn something at same time.
if you noticed the battery power has no decimal the 1 is used.then it is only 2 digits and one decimal .
the power incremented sequentially when turned on one digit at a time too update this is the update polling frequency.
next video is you rebuilding your usb tester to make it more lossless.
and time to not use wall chargers and use a variable power supply.
great work btw it was good as always.
the battery without cuts, the one where the capacity is readable is perfectly reusable without problems.
Just keep in mind that, looking at the connections between the two batteries, it has absolutely no protection circuit, so do not short-circuit the two poles to avoid fireworks.
Hello and to the next videos
NICE video
Bloody marvellous
The tool on the bottom right is very useful if a bolt doesn't want to turn, the tool grips and won't let go.
I loved the cat's comments!
I just knew that @24:18 when everything was crazy dark, that it had finally finished charging but not until late!!! But then you started whispering, plus it’s dark & my first thought was “I bet you anything that his girlfriend was sleeping!!!😴 But he was so excited about his new toy being ready that he said F-it & just started filming the second it hit 100%, even if it was the middle of the night!!!🤣🤣🤣” but then the next thing you said was about how your girlfriend was asleep😴 & you can’t use much light💡either!!! I’m still laughing from that!!! 🤣🤣🤣
The answer to low current when cheap cable is used are the data lines missing from it - most chargers won't supply more than 500mA if device connected won't request it (USB standard says it should be 100mA).
And I think that some powerbanks also won't charge using full current when used with smart chargers respecting USB standard.
please make a video on IGBT based Welding machine and explain how it works. thank you
The way he talks makes me feel squishy🤣😉
😆😆
24:18 Sneak 100
That mysterious chip communicates with the device that you are charging and telling it that the powerbank supports fast charge
Risk of fire and bEErnnzz 11:08 i love the accent lol
Thank you for this nice video. I didn't know the cheap usb connectors can be that effective on the power draw. I will definitely check mine.
4:43 Hahahaa, you are so funny :')
I actually use an app that tells me when my battery is at about 85 percent its called accubattery and it has a lot of info on your battery its really awesome
Too bad it is only on android. 🥲
ok can't you just look at the percentage normally?
or do you mean health?
@@tylern6420 c orrect
@@tylern6420 its more for the health of the bat not the percentage
I love your vídeos. BTW I am the kind of people who find orgasmic to remove the plastic film protections. xD
I keep the protective sticker on things too. It keeps screens in better condition for longer...
That unmark IC near the 7 segment LED is prob the TM1637. Love the video.
I don't think that the unpierced cell is damaged. The pouch doesn't really add any mechanical strength, it will just keep the electrolyte in. You have to handle these pouch cells pretty badly to damage the internal construction, because the layers are tightly packed. Even the pierced one will work as long as you patch the hole. If the solvent for the electrolyte evaporates it will stop working and oxygen getting in will oxidize the active chemicals also stopping it to work.
You could open the pierced cell to show its construction and see how much "reserve" there is before something would go wrong.
And while at it, open an 18650 as well to show that they are the exact same thing just in a different form factor and dispell the myth of the "lipo" and "li-ion" differences. There is no inherent difference between what people call "lithium polymer" and "lithium ion" batteries, except for the shape. The shape doesn't tell you anything about the chemistry inside, although pouch cells (that's the proper name) are most often what would be labeled "ICR" or "LCO" in cylindrical cells. Talk to battery manufacturers and they will tell you about packaging type (can, pouch or prismatic for example), but they are all li-ion batteries.
You seem to be taking it dangerously
From 24:18 on, it becomes unintentional ASMR geeckery :)
my father was a long haul truck driver and he had wrenches that were almost a meter long.
I think there was no calibration during the first cycle. That percentage display is simply showing VOLTAGE converted through a hard-coded conversion formula. When you discharged with 2A the inner voltage drop was higher thus the display started counting down earlier.
Recently, i made a large power bank with a capacity of around 45 amp hours, added up from tested 18650s from laptop batteries. The batteries were free, and the cost to construct it was about 7 dollars. Also, 33:00 your cat is so cute, purring like that.
Did you use a DIY powerbank kit for it?
@@tylern6420 no, I bought a board on amazon, and a pack of 18650 plastic mounts that connect to each other. I wired them all in parallel. The batteries came from old computers I took apart.
@@fungusenthusiast8249 a powerbank board? What about the case?
@@tylern6420 I just wrapped it in electrical tape, no case. The board was one with a micro usb charger and two usb ports
@@fungusenthusiast8249 does the board have an led indicator too?
The voltage on the discharge curve drops fast at the beginning, but most of the energy is still there. It is not incorrect to still show >95 percent below 4 volts.
The cable is so, so often overlooked with charging performance. If you have *anything* that charges slowly, and I do mean anything, try a nice cable. I really love the Monoprice gold plated cables. They're very reasonably priced, and last forever in humid climates, which is saying more than you could ever know unless you live here in the tropics.
Great videos. Can you recommend the cheapest DC volt meter that is accurate?
Please make the video in 2 parts next time ?
Part 1 and part 2 please ... It's easy that way to watch actually..
In 10 parts it's even easier. xD
You can just pause the video and watch the other half the next day if you brain is overheating ;).
4:39 i died😂
When you would make a video about how that yellow DT830 multimeter measures power usage ?
Chef, you did the job 100% again 😀👍 A+++ both the tests and the video. My curiosity lacks one last thing at ~27:45..When you have first completely discharged over the ports, it would have been interesting to see where (what voltage) the circuitry had cut off. Have you happened to measure it? thx! and greetings to your buddy 🐈!
Good video. I enjoy all the details.
DGW: I won't remove this sticker to protect the LCD meter.
Also DGW: this is going destructive it won't come back together.
What’s that I see 👀 peeking into the top center of the frame @29:10??? 🤔
Is that the random sprig of solder that you used for “So now the Analyzer is soldered directly onto the Contacts of the Battery!”??? I was watching that part & didn’t notice the solder until I saw your lamp reflecting on your table in a quick flash as you moved the camera around the shot. So I rewound and yup, that’s definitely a random strand of solder right smack in between everything!!! 🤣🤣🤣
Can you test if your cat is safe enough ?
You can seal up the battery again with glue and or tape!! The can of 18650's are more explosive than a lipo. Those tend to swell up, which disconnects the internals so it can't generate power which stops any fire or problems.
31:57 showing a coundown display when you wake it up might not be a desirable feature if you're asked to demonstrate it at an airport security check
*bomb has been planted*
The unknown chip is for Qualcomm Quick Charge 1.0 or USB Power Delivery functionality probably.
I wish you could teardown anker 30,000 mah power bank battery and use your clamp meter to see the fast charging 3 current
How i select a good charger
Hi @DiodeGoneWild! Your battery analyzer at 25:00 looks not dodgy at all! How about an article on that? Bloody hell, I'd like to have such a beautiful tool too :)
The cat was right! The case is mangled, but the display still looks great! :-D
Shed loads of info and very funny ....cheers !
Don't worry about the the hole you can easily patch it with Kapton tape with super glue, my battery is much worst it's bulging but what i did I poke a needle in it to release the gas now its working fine
I like the way you speak..
Awesome as Allways...
@ ~10:00: The current is so low because there are no data lines in the cable. So it assumes it's a normal USB port and only draws 500 mA.
I have a larger unit branded Romoss. It has 2 flat cells like that, but marked 10000mAh each. Same arrangement, two in parallel. It no longer accepts a charge so I assume the cells are dead. There is room in the case for 7 18650 cells. My plan is to wire those in parallel, and if I can obtain cells with 2200mah, that's about 15000mAh. Does this sound dangerous or stupid?
The old interference filter from taiwan is labelled "clignoteur" which means "blinker" in french. Maybe for a light? Thanks a lot for sharing. Hope you'll do your van roadtrip, with lot of low tech knowledge!
Saw the video after 3 mins of release.
Only reason i subscribed this channel because of his accent and knowledge 😂
Night time ASMR!
I really appreciate your work and love your videos.
Please make more videos 😄😄
I guess you doesn't have to translate cuz you have correctly explain on the manual,(待机standby100uF ✔,效率efficiency 92 % ✔) looks like you're really good at this !😮 nice
So you didn't get injured during the Enermax PSU experiments after all... that's niiiiiiice :)
I once opened a power bank they don’t use extreme glue but it took a little patience to separate the battery’s they had no damage
It is a good idea to buy a Camper van. I bought a little bigger than just a van, I bought a old Iveco Daily 40-12 Mobilvetta Icaro, because I will have more options and space. I'm often at radio ham Fielddays and Flohmarkt (? Don't know English) market for private selling surplus electronics. I can really recommend, and with bigger mobile home than VW van you will be able to drive the world with your cat. Lot of Campers do that and cats obviously like it. If you want to drive away from big tourist routes, try not to buy something with front drive FDW. There is even wet gras a big problem. Front axle 700 Kg with all the engine power and 2500 Kg rear axle you will imagine how bad this is. After my all wheel drive Unimog and Ducato now I have Rear wheel drive with double wheel at the rear axle and I can say, It is astonishingly good. 5 star is AWD with differential locks, 3 star is normal AWD, 1 star is rear drive if weight is at rear axle and minus 10 stars is front drive with weight at rear axle.
TloadD would be 32s shutdown
TOnDebounce would probably be internal button debouncing so that when you press the button, it doesn't register twice, for when the thing is programmed so that the button both turns it on and off. In this case it looks like the threshold is 50ms.
TKeylight: where fitted, holding for 2 seconds turns on the light. This chip looks like it has a relatively high power LED driver onboard so it makes sense that it would do this all in-house.
TOTP: overtemp protection
No idea what 'T' refers to, or at least I wasn't paying attention, but it makes sense that this would be what those things mean.
I like his accent, if only my college professors sound like him.
The odd 6 pin chip for the 2.1A side is probably very similar to a TPS2511. It's used to negotiate the supplied current to the USB device being charged.
The 16 segments of the display can be driven as binary via 5 bits = 32 combinations via a simple BCD converter. ;)
The battery having a small hole in the outer foil does not damage the actual cells inside. In fact it's not a bad thing to have a tiny hole (like a needle pin size) because it allows "venting" in case of gas forming. There's no need to worry so much, as long as it's not danged deep inside. Trust me, been doing mobile phone repairs for over 20 years. ;)
By the way, it's no longer true that phone batteries get damaged by charging it to 100%.
Lately phone manufacturers program it to display 100% but in reality the internal charge capacity of the battery tops out at about 80-90%. So unless you're using some older phone manufactured before 2018, then you shouldn't worry about charging it to 100% internally. ;)
shouldn't a battery be discarded when it inflates tho?
ainope is really coool
Note to self: 26:55! Charge should operate between 10 and 85 percent displayed!
lol the end, I ended up without powerbank but at least I have this cable, this deserve big like , but there is only one standard button for like so I had to write this.
I have a very important question about the current. I have a battery where it have 3.7v 21000mah and I need to power something where it needs 30v 3000mah. I by a step up converter. And I do the math and I found what my device it runs for not a hour. Basically i found what the mah its 2590mah. So this is true what it gone be run ~40 minutes???? Please if you read this comment please answer me...(sorry for the bad English)
Hi is your furniture still wrapped in plastic like my Grandma?
won't remove small sticker on the display ,later destroys whole powerbank.
Hi. May I know what brand and model is your fire extinguisher? I would like to source it and try it.. 😜
You destroyed it from both sides with the knife and screwdriver but at least you kept the peel on the screento look like knew after 5 years lol :)
