Just purchased this device to recharge my tablet and phone on the go; however seem to have got a faulty one.
I charged it up so that all four blue lights were showing when I pressed the button.
I then recharged my phone from 50% to full, then recharged the Power Bank - for a while all seemed well with 4th light flashing showing it was recharging. After a while this stopped and all lights off - then just one blue flashing light. It will now not recharge anything nor accept a charge.
First time this happened I returned as faulty. Now the replacement has done exactly the same. I have got a refund
Have I done anything wrong? Two faulty Power Banks???
Any ideas?
