When I got this item it was at about 63% charge and wouldnt take any further charge from there - 2 days worth of charging with the provided cable, plugged into an adapter plugged into the wall. 3.1 amp charger. Worked great even at that charge percent, and actually took a little bit of charge after that - back to 63% and now wont take any more charge. Probably going to return next week.
