So far with my powerbank from one full charge I've charged 6 smartphones (my personal mobile twice, work phone, wife & 3 kids phones once each), my nexus 7 tablet twice and a set of bluetooth headphones. After that 2 out of 4 lights were still on (in fact the 3rd light only went out about 15 mins before I was done).
My previous powerbank was 12,000mAh but could only charge a smartphone 2-4 times and wouldn't do anything for my tablet.
So far I'm feeling pretty confident with this one, especially given the reviews from a variety of sources. I'm doing my usual 'checking to make sure I'm getting what I paid for' testing though before I even think about throwing the packaging away...
