¿How to fix a power bank extreme?

[AC Question]

Hi everyone, I need to know how to fix this "XtremeCables 5200mAh Insta Power Bank with Digital Display"

The power bank does´t works it just won't charge, and the display only turn on when its connected to mi computer.

Sounds like the battery isn't charging and the display is powering off the incoming power from the computer. Can you try charging it using a dedicated wall-wart charger? It's possible the computer can't provide enough power to charge the battery, using a dedicated charger would resolve that.

How old is the battery pack? Have you checked to see if you have any warranty on it? Have you tried contacting the manufacturer?
