Hi, recently my Samsung Powerbank stopped working. I was using it for my LED's, it was just plugged there for like 2 weeks and not used much. And now, when it ran out of charge I unplugged it from LED's and plugged it into charge, and suddenly all 4 lights started blinking. It's the same for like 4 days now, it just blinks non stop. For charging I used Xiaomi charger (max 30w) I used it all the time and nothing was wrong.
I tried looking for the receipt, because I bought this powerbank recently and now it just died, but I think I lost my receipt somewhere so I don't have it.
I also tried some solutions I found online, like holding the button or waiting 10 seconds and charging it then, but nothing seemed to work.
Looking for help, thanks
for anyone looking for the solution for the exact same problem, just open the powerbank and reconnect the battery, it fixed it for me. Only problem is you will need an soldering iron to resolder the battery
