I had the same problem. I did a search. I found that the USB cable that comes with the Bank is of poor quality. I had an Original Samsung USB cable and connected it with the Power Bank. Bang it works now it charges the phone.
Change your cable to a thick one not the the thin type and you will be ok. Glad to help. I hope this will help you
