5000mAh Power Bank with High-Speed Charging for iPhone, iPad & Samsung Galaxy & More Smart Devices (1 Piece)

I was really excited for this item, BUT. It took over 8 hours to charge it and after half an hour of my phone being plugged in it only went up a few (less than 10) percentage points. By then there were only 2 green dots (battery display) lit up, indicating it took 3 to get those few percentage points. No way is this thing going to charge a phone or two.

Weighs a heavy pound so too much to carry around. Doesn't charge my galaxy s7 or tab e and is slow charging anything it will charge. Very disappointed.
