Anker PowerCore 20100 Nintendo Edition are not good powerbanks

#1

Good Day!

First of all sorry for my English.

Several months ago, I bought one Anker PowerCore 20100 Nintendo Switch Edition, but after like few weeks of using, it suddenly stops charging my switch and my phone, and it won’t received charge also from Nintendo Switch charger or Anker PowerPort Wall charger. Few days ago, I purchase again the same unit and still has the same problem.

I already tried to use another cable from anker too, but it doesn’t work at all. I already tried to reset the PB by looping the cable from Type-A to Type-C, still doesn’t work.

I always use the Nintendo Switch Charger, Anker PowerPort PD+2 with Anker Type-C to C cable, and Google Pixel 2xl chargers. I never used any generic chargers or cables on those two powerbanks.

The first PB were totally at 0% battery level because when pressing the button, only one LED is blinking so I can’t test if the Type-A port is working.

The second PB has atleast 75% or 3 LED light so I can still use the Type-A port and it works, except the Type-C port has problem already and it won’t receive charge also from Nintendo Switch charger and the other two chargers.

I tried to overnight charging these two Power banks using those three chargers every other day but still it doesn’t receive charge at all.

I tried to borrow cables and chargers from my workmates and friends (to make sure mines aren’t faulty) but got no luck. My chargers are working properly as I always use on my phone and other Type C devices.

I try to charge the first PB by using the second PB (Using the Type-A from 2nd PB going to 1st PB Type-C), those LED lights from 2nd PB is blinking but the first one doesn’t. Not sure what it does mean though.

I am aware that my power banks won’t cover any warranty at all because I purchased these PB on eBay (not the Anker Store due to I live in remote US Islands). The first power bank that I’ve purchased is brand new and the second one is used and I bought it like half price but to get two consecutive PB that has same faulty Type-C port is really not good at all.

I wish that we can exchange these power banks to new ones, I don’t mind paying few extra bucks as I know that my power banks don’t have any warranty, I just don’t want to throw or dispose these power banks because they are harmful waste. At least, if we can exchange or return it to the Anker, they can repair or recycle these faulty power banks.

Still, Anker have great products, my PowerPort PD+ and Anker cable serves really well. But I will never get these PowerCore anymore even the small one. I live in remote US islands and direct store won’t ship here anyway.

thankyou for you opinion

When you went to charge them did you make sure all lights were off first? Otherwise your powerbank will try to send a charge and not receive it, hence why it may not charge. All lights have to be off before plugging in the charge cable

Yes, I did that too before. Still it doesn’t work. I even try to do plug-in order to make sure my power bank will going to receive the charge but no luck.

Interesting. I own two of these battery banks, and they get used pretty frequently by multiple people. They both have over 200 charge cycles each, and are still going strong. Maybe contact Anker and see if you can get them repaired. I would definitely call this unusual.

Do have a similar issue. I plut it in and it goes from 1 light to 2, without any problem. After, nothing happens. The 2nd light keeps blinking and no more charge is happening.

Any advice?

What is the output rating of the charger you are using? And how long did you leave it to charge?

I just purchased a Switch and the power bank, and this also is happening for me. Both brand new, and I immediately plugged it into the Switch AC adapter and left it for a day, but it is still on 2 lights.

Hello 2019 myself, I’m replying to your post now at 2025. Glad that we made it through to those pandemic times.

I still remember the frustration that I had on these 2 power banks back then. We had bad typhoons and no power for several weeks at that time so I had to charged my devices on my work. I also contacted the support too but sadly, they can’t/don’t fix this kind of issue, I mean that sending these power bank to them just to fix the port even if I had to pay for it since these two PB don’t have warranty at all.

I thought that these 2 power banks will end up in a land of waste but I’m glad to the 2019 me for keeping it. Or rather, sending it to my brother for him to keep those power banks.

Fast forward 2025, several months ago, my brother’s power bank (other brand) got inflated battery inside and he’s looking for a new one. So instead of buying new one, we decided to open up again these 2. I’m sure for all those years kept inside the cabinet, the battery should be 100% drain. I’m glad that it’s not ded though. So we push the button and no LED light blinks or turn on.

So we tried to test it again, charge it on the very same charger, Anker PowerPort PD+2 with Anker cable (Yes, I’m still using it and it’s still working great) and the original Nintendo Switch Charger. Lo and behold. It works! the LED lights blink again. After like few hours of charging and got full, the Type C port on the 2 Power bank work again like brand new! So in my conclusion, you have to reset these power bank by draining it’s battery inside. Though, in my case, it took 6 years. Lol. Within those years, I forgot that I had these faulty PBs. I don’t know any other way to drain the battery. I don’t want to open it either because i might break it completely if I did that.

Although 1 of the power bank got the same problem (Type-C port is not receiving/giving charge) again after few weeks of using. So probably, I have to play this long waiting game again just to drain the battery 100% in order to reset the power bank. Since looping it doesn’t work (Plugging Type C to Type A USB on its Power bank USB ports).

Still, I won’t take back my words that these power banks are not good, nor I won’t say it is worst at all. It’s just okay, an expensive alternative power bank, if you want the Nintendo logo on it. Just get other power banks that can charge your Nintendo Switch or other devices without having these issue.

Thank you again for the suggestions, my past 2019 me probably did all of your suggestions even way before posting it here at community. At least 1 of the PB works again with my same Nintendo Switch that I had since 2017 and the very same Anker PowerPort PD+2 and its cable.
