This is a solid unit, compact, sleek. It charges with a  micro-usb plug common to most non-IOS devices these days (rather than the older larger mini-USB). Oddly, it features a 1-LED flashlight and a laser pointer as well. I suppose these could come in handy while camping or something, but since all 3 functions are operated by the same single push button it can be tricky to activate the charging rather than the laser or the light (which is activated depends on how long you press the "on" button). I'd prefer a separate switch for the laser/LED lamp.
