Works as expected, gives my phone about a 1x charge so doubles the capacity of my phone in a pinch. Nice color, build quality seems solid, but the LED indicators are very confusing. There are a bunch of led's in a row and only some are used as the battery gauge, the others for status...

In any case, I wish it had a little more power for the size, but all in all, I like it. I've never wanted to use the second usb port either, I'd get rid of that...
