Got this for a long flight, used it to power my Galaxy S 4" Player, It works like a charm I get an average of 2.5 charges out of it. Holds charge good, the torchlight comes in handy, the laser pointer is pretty much useless (to me anyway), the supplied usb chord is durable but a little bit bulky. During the charging of a device it does get a little warm. When charging the unit it self it gets a little warmer, but that is expected.
