Faulty Anker PowerCore 20000mAh Power Bank | Can I Fix it?

In this video we're going to be taking a look at a Faulty Anker PowerCore 20000mAh Power Bank. I purchased it from eBay for spares or repair, and it was listed as not charging, but the output still works.
Caution should be taking when working with lithium cells due to the potential fire hazard.
I'm not an expert, but I do enjoy trying to fix things.

I dislike all those manufacturers making opening their product for repair a destructive operation :(

[@BuyitFixit]

Agree, it definitely seems like they don't want people in there.

​@@BuyitFixit I agree too. They don't like people or repairmen in there. A couple of screws don't hurt anyone.

I went through 3 of those exact powerbank all with precisely the issue you had. I found that if they are left discharged for any great length of time, they s**t themselves and die, then subsequently refuse to take a charge. Good job on fixing it!

[@BuyitFixit]

Thanks Alex, interesting that it seems a common problem 👍

@@MrCowH Sounds like this might be a fairly common issue.

[@caramba10]

This was extremely useful, I have one of these that failed but couldn't figure out how to get it apart, I'd assumed the lid was glued in place so might give it another go. I should add it failed not long after buying it and Anker support sent me a free replacement and didn't require the old unit returning which I thought was pretty good customer service.

[@BuyitFixit]

Thanks 👍or perhaps they know it's a problem and happens often?

[@xzytqweo3538]

Thank you for making and sharing this video. Now we know what it takes and does when you open the case and that sometimes is the biggest problem for most electronic devices today. Just depends on the manufacturer...and most are the "use and then throw away and skip the repair ability"...cuts into their profits.

[@BuyitFixit]

Thanks 🙂Yes agree, it's sometimes harder to work out how to get into something than actually repair it.

Its not just because youre not supposed to repair them. Its also about the looks. Customers dont want devices with visible screws or visible screw covers.

Wow, nice fix ! I bought 6 or 7 of the 20,000-mAh Power Banks for USB lighting when the power goes out. I bought several 12" and 19" USB powered LED Under Cabinet lights, to pair up with each battery bank. Lots of light, and they go anywhere I need it, without toting about some huge "SOLAR Generator" just for a bit of light. Great video !!!

Honestly one of the best repair jobs i’ve seen especially with your explanation of the process in a detailed manner, i bought this same unit two weeks ago and i’m facing the same issue, i always wondered what would be the cause for it, already contacted anker support and hopefully they’ll send in a replacement, in case i get to keep the old unit, I’ll probably use your video for reference and repair it. Thanks mate.

[@BuyitFixit]

Thanks for your feedback👍 the hardest part is getting it open!

[@inothome]

Nice easy fix, once you got in to it. What a pain to open up! I have replaced a few cells in power banks but never any luck on the electronics side when they fail. Never a lose inductor or connector. I think the one chip is the BMS for the cell and the MCU controls the PD levels of output. Since that one controller didn't have any data lines connected, just the positive and negative connections. So no way to interrogate a charge level without the data lines. But, that one schematic you showed could have just been one option too, not sure if other options.

[@BuyitFixit]

Thanks, yes there was other options on the main chip in the PDF and there was pins on the chip that match the rest of them on the USB C called CC1 CC2 DMC DPC but I didn't look into it too much with it being written in Chinese. A few people suggested Google lens so might have another look 👍

[@chuckbenedict7235]

I call this MFD...manufactured for disposal. Clear that this was made to be thrown away. Also clear designers knew drops would cause damage to inductor...thus the goo, instead of a different design that would actually prevent inductor from breaking away. Thanks for showing they can be fixed. And in particular...how the case is held together.

[@BuyitFixit]

Thanks 👍yes MFD 😂😂

[@marcyd2007]

Another nice little fix Mick, well done. A nice little Power Bank is quite handy to have available. I use mine a lot for powering little electronics projects I'm working on like Arduino based stuff for example. They're great for testing before giving the project it's own proper power supply. The only downside is that sometimes they auto power off because I'm not drawing enough current, but still a handy thing to have on the work bench for sure.

[@BuyitFixit]

Thanks Marc, yes I'm sure it will come in handy 👍

[@user-xl5np5dp8n]

Little anecdote for you- I was futzing around with a similar unit. Got it open, and while poking around at its innards I managed to create a short. The unit started to smoke, so I jumped up, grabbed it, and took it out quickly and left it on the concrete patio. It then caught fire, and gave a good show like a firework. I wasn't going to hit it with water. So, a lesson well learned that time.

[@BuyitFixit]

Glad everything worked out ok for you. I usually try to see what state the cells are in first, fully charged are a lot more energetic.

Yes definitely a pain 😂😂Thanks for the tip 👍

[@colinmalcolm1211]

I think the micro controller handles the differnt voltages and current for which ever device you a using. Examle fast charge for phone's etc. I also think it also controls the trickle charge for a completely dead battery then changes it to normal, then stops it.

[@BuyitFixit]

Could well be. Thanks for that 👍

[@maicod]

oh right QC 3.0 then as it has a Type-A plug on the charger side and still is able to handshake for 9V (PD only works over USB-C to C if i'm right)

[@bootsowen]

I have found quite a few power banks in the student scavenging every June. I got an old Anker one this year that looks like it has 4 18650s in it. It's about that size. I got one like your Anker in the battery recycling bin an Aldi last week, similar battery had swelled, dislodging the solar panel that was on it. So I guess they threw it out. It's a neat little panel, though how long it would take to charge from the panel is anyone's guess.

[@BuyitFixit]

Hey bootsowen 🙂 yeah I guess it would take quite a while to charge with a little solar panel.

[@The_Repairman_Workshop]

Great fix once again! have you ever tried using your hot air station to warm up the warped plastic with practice screwdriver method you used can get decent results.

Thanks Vince 🙂Yes nightmare to get into. I'm pretty sure done on purpose. How did you get on with your ender 3? I bought a faulty ender 5 pro, was going to do a video on it but it had the old 8 bit board in it, so just ordered a 32 bit one so it would have been a fairly boring video I thought so didn't bother. Had a nightmare with firmware though, as the manufacturer's version is about 2 years out of date and printed backwards. Ended up having to compile my own from the latest Marlin. All working fine now though and busy printing cosplay stuff for my daughter 😂😂😂

My brother just recently gifted me one of these for emergencies. Part of me understands why they don't want people messing around inside of these. It's a lot of juice and if you puncture the pouch cell things could get nasty, at the same time I wish it wasn't intended to be so disposable, especially if it seems to have a known weakness in that part breaking.

Very interesting video, I have this exact same power bank I bought years ago on Amazon, when I plug it into a usb to charge the lights flash but it doesn't actually take any charge, I have to keep unplugging it and reconnecting it for ages, eventually it does start charging, I wonder if the same component solder is fractured and needs reflowing?

[@BuyitFixit]

It could be, or it might possibly be a bad connection on the USB C port or damaged USB C port. That's what I thought would be the issue with this one before I opened it.

I have an Anker power bank that didn't work too well after a year and a bit, so I took it appart (same problem getting the case appart ) it has four round cells so I ordered four from a on line vape store, when dismantling the pack, one had not been connected so it was operating on three, it has lasted a lot longer since.

[@BuyitFixit]

Nice 👍yes it would only have been running at 75% capacity with 3 cells.

[@jamescoia543]

I have a Lidl branded Tronic TDP 10000, and is quite similar to this but would output fine, mine would not charge after a few cycles. May need to charge it externally to see if the cell is bad, bit think the charging regulator forgot how and at what rate.

[@mostwanted33986]

5:10 well that sound 😅 I actually thought that the battery is about to explode

[@BuyitFixit]

😂😂😂😂

[@H2Dwoat]

Hi, interesting video 👍. Do you think the goo was purely for securing the inductor? There seemed to be similar/same goo around a capacitor as well. I suppose product testing may have found a propensity for those components to break free when the bank is dropped. I can’t imagine it would have been applied unless there was a known issue, companies don’t tend to go to additional expense unnecessarily. Is there a way to test the inductor before resoldering it to the board? Now you have opened it do you think you have a better method if you were to have to open another bank?

[@BuyitFixit]

Thanks 👍Yes I think the glue is purely for mechanical strength. I've seen similar on some other devices especially with larger components. I think it might be possible to hot glue a handle or something to the lid, or perhaps a suction cup and try to pull the lid off, but I'm not convinced.

[@zs1dfr]

[@BuyitFixit]

Hi Alex, I'm not too sure on that one. I've seen inside a few but they are all pretty much just a battery with a control board. You could always make your own (which would be more serviceable) as you can buy power bank boards on Aliexpress for around £2 or so. www.aliexpress.com/item/1005005649223878.html then hook up some 18650's in parallel (you can get 18650 holders too)

[@Roobotics]

Very likely poor soldering flow due to the large thermal mass of the inductor, if they never dialed this in or tested for it with vibration/shock, it means they might all suffer from a very weak and 'dry' solder joint in this area. I've reflowed many components, and inductors like this with high weight density, definitely take some work to do right, more-so than many other components.

[@BuyitFixit]

Yes, sounds very likely, also I think unleaded soldering is a lot more brittle than leaded. Thanks for commenting 👍

Powerful suction cup could work. Theorically.

Yes, I did think that too, once I knew how it worked. Even perhaps hot gluing something to the top of the case and then use IPA to release it. I'll have to keep a look out for a decent suction cup 👍

[@AndrewCalhoun]

There is a PowerCore 20000 and a PowerCore 20000 PD. Perhaps the PD version has an extra microcontroller it uses to communicate with devices to negotiate how much power it sends? Even if this is not the PD version, it could still have the extra microcontroller inside but just not enabled or something.

[@BuyitFixit]

Hard to say. Are there any surface mount fuses or links like zero ohm resistors on the board. I'd be checking those, and I'd check for shorted mosfets. It could be anything from corrupt firmware to a failed IC or a bad connection under an IC. Hard to say without testing things.

[@Gengh13]

Looks like it wasn't soldered properly, the inductor being the highest thermal mass component with wide tracks I would guess that the reflow profile wasn't adjusted properly for that part. With a good rework and the extra help of leaded solder it shouldn't come out again.

Yes, I had been thinking was it the use of non leaded solder, as I think it's more brittle than leaded. I had a similar thing in the last video with the induction cooker.

[@kumarsajal8400]

By the looks of the thickness of that battery cell, I highly doubt if this is a 20000mAh power bank. There are just two 5000mah cells there and so it's a 10000 mah. And don't mind, but buying a 10kmah for parts powerbank for $6 is foolish. Because those cells in there are generic chinese factory made that costs just under $5 new.

How did toy clean up the silicone almost completely off camera? Is it ok that they foil hangs over the board loosely and maybe shorts something? EU lawmakers need to move faster to force such devices to be openable.

[@BuyitFixit]

Just some IPA and a toothbrush seemed to remove the silicone nicely 🙂

[@SlartiMarvinbartfast]

Don't you just love those simple fixes? 🙂 Nice repair. Removing the annoying lid of the casing was the worst part for you - yet another example of a company that doesn't want (or can't be bothered) to make their products repairable and instead most faulty units end up as landfill. All countries need to pass and and rigorously enforce laws to ensure that all electronics and other devices (mechanical and otherwise) are repairable for those with the right skills, but of course it'll never happen because too many governments and politicians are in the back pockets of the large corporations as well as indulging in the usual political and trade machinations with China, etc.

Thanks 🙂 yes not very serviceable was it...

[@williamharris8367]

Even with such Legislation, the _vast_ majority of consumers lack the skills, tools, and motivation to repair things themselves. Repair is only a viable option when the cost is significantly less than replacement, and no professional can work in such an environment. A co-worker was recently in a major car accident. His vehicle suffered massive damage, including a bent frame, to the point that repairs would cost more than the value of the vehicle. He has the "right" to repair it, but it makes no economic sense to do so.

What is the model of this tester ?

[@BuyitFixit]

I'm not sure of the model, I bought it from AliExpress this is the one I bought here: www.aliexpress.com/item/32854809579.html

[@christophermarshall5765]

Nice fix. Bloody awkward things to open they are.

[@BuyitFixit]

Thanks and yes 😂😂😂 nightmare they are.

[@loronzosgorbonzo974]

I bet this is the same issue I am having. Bought a brand new one that won't charge, but came fully charged and it worked fine until I went to charge it.

[@BuyitFixit]

Could well be.

[@ronwade2206]

Bad solder joints, a few cold ones too. Cheap cheap etc

[@alextoppen]

Flashing single light on Anker means 0 battery.

[@BuyitFixit]

Thanks, yes I worked it out eventually 😂😂😂

[@fu1r4]

9:12 It is obvious that the manufacturer knows about this problem or else they haven't put that goo there. Unfortunately you are doing the same mistake. By putting solder on both sides it will add stress to the solder tracks and the solder. Add solder to one side, solder it and then add solder to the other side when the component lies flat against the surface.

[@BuyitFixit]

Although one slight difference is I'm using leaded solder which seems to be less brittle than the unleaded.

[@MooTaters]

Different model but similar case, just a bit chunkier(27k mAh). Also just stopped taking a charge one day, just heats up.

[@BuyitFixit]

Heating up doesn't sound good at all...

[@devpashupati9168]

I have mine the output in not working but I can still charge it but don't know how to fix it.

[@BuyitFixit]

It could be the same fault as this one. You would need to get it apart first, which is a bit of a job.

[@user-ew3qj5sn2p]

Is that why you can't get there?Might have been rubber did It's possible that that red or blue was to hold it , but apparently a brook loose

[@user-ew3qj5sn2p]

Check that resistor there might be some registers out

[@vanmanhnguyen2629]

can you tell me battery name?

[@BuyitFixit]

Sorry, I don't have that. If you measure the original battery you might be able to search for it on somewhere like AliExpress if you need to replace it.

[@nttasnim-7639]

I also face same problem 😥. How can i fix it 😢😢

[@BuyitFixit]

I fixed this one, the biggest problem is getting it open!

[@pjmelect]

Why is it that whenever I repair electronic equipment it is never a simple fix like this one, although opening the case seems normal.

[@BuyitFixit]

Don't worry I've had my fair tough ones too, a bit like the JVC a few videos back.

[@BuyitFixit]

[@cajuncoinhunter]

Another easy fix , chaulk another one up on the white board as fixed ....... Wait I don't think you can use chaulk on a white board LOL...... Oh well it's fixed anyway ....... Take care Mon Ami ....

[@BuyitFixit]

Cheers mate 👍🙂

[@erg0centric]

My theory Assembler was told to ppt silicone on both sides but was lazy. Silicone shrinks while curing and stresses solder joints instead of supporting them. Amazon driver throws package at front porch, lazy.

[@BuyitFixit]

Very plausible, could well be the case 👍

[@maryanne7tye]

Also the wires are not attached on the front of the device anymore either

[@jasejj]

Chinese manufacturing at its very best. "Aspire to be adequate!"

[@BuyitFixit]

😂😂😂😂😂👍

[@josephneale10215]

love anker power banks and usb power supplys

[@BuyitFixit]

Yes they seem well built 👍🙂

[@lakak4056]

If there is one or two of the cells stronger than the other you can get it to charge by discharging the stronger cells down to the level of the weak one. Then charge as normal.

[@BuyitFixit]

I think this is just a single cell, I could be wrong though..

[@bernardperaldi7488]

Hi, if you want read chinese or other language you can use google lens .

[@BuyitFixit]

Thanks 👍a few other people suggested that too 🙂
