It's been used less than 3 times, battery power lasts forever; I haven't had to charge it once since out of the box. I'll take pics as soon as I get the chance. It even still has the plastic film still on it that it came with.
It's discontinued now since they came out with a more expensive one like everybody else, but it works perfectly, and is a very small size considering how much power you get.
Over 6x the battery power of my nano 2nd gen, comes with wall charger, cable, everything that came in the box. I used it to charge my nano, but it's advertised to work with the iPhone and other models.
Bought for over $60 after shipping, $45 obo takes it, and I'll even drive to meet you somewhere.
