Quality: Visually, the device fully convinced. It looks very solid. Apparently aluminum was processed. So far I have no scratches on the surface, despite almost daily. Use.
Charging: go quickly and by the included USB cable also practically on the computer. But you can also use any other micro-USB cable.
Charging (mobile): Here convinced the device despite only 1A output with fast charge. Even my Asus T100 Tablet is loaded.
Capacity: HTC Evo 3D ca 1.5x. Tablet is only "upload is" and is not completely full.
Gadget: The flashlight is nice and bright and works perfectly. Unfortunately, this makes also the only point of criticism. Now, after three weeks of intensive use this on during the charging process and not just automatically again. That does not bother especially at night when "the lights go on" at once;)
All in all a recommendable product. Especially very small, handy and easy to transport.
