Powercore 20100

I have this battery, https://www.anker.com/products/A1271012

When I charge it up with a 2amp 5v charger the chging brick gets very warm and right around the input on the charger gets warm. Is that normal?

It really depends on how warm you mean. If its only just a bit warm around the input then charging that’s normal.

If it gets any hotter than you can stand to touch then that is not normal & you should see if you can have it replaced under warranty.

It is normal for both the battery and the charger to get warm while charging, especially when charging at 2 amps. If it becomes too hot to touch or you smell burning plastic, then that would be cause for alarm and you would want to disconnect them immediately.


Couldn’t agree more with @TechnicallyWell . When you get to the too hot to touch or burning plastic stage, discontinue use and contact support for assistance and/or replacement under your warranty
