Got this battery bank as a second back up to my normal one. It's sleek light and packs a lot of juice into a small body.
Bank charges via micro USB has 2 USB outputs one at 2.1a and another at 1ait also includes a little torch led so could be used in a pinch.
I would only change the pack to have 2 x 2.1a ports otherwise its a great battery at a bargain price.
