I purchased this powerbank as an "emergency" back up for my Note 2 and Note 10.1 tablet.
In one go, it charged my Note2 from 9% to 100% and my Note10.1 from 30% to 82%
We had a massive power outage last October and I was really wanting to use my tablet and phones however the two day blackout drained all the batteries and powerpacks. In fact I have not used it often and just to keep my phones and tablets running while I am enduring the bloody outage again.
