I have a new 10000 fast charge power bank that I took care of and barely used. suddenly it stopped holding power in it. when I plug it to charge it, it keeps blinking (one light) and after a long time, it holds a very small amount of power that is not enough to chare 2% in my Note 9.
if I plug it to charge it and at the same time I charge my phone from it, it delivers normal fast charging.
I'm traveling overseas and no one is willing to fix it for me.
thank you, everyone!
