The Power Case fits well, the iPhone makes comparatively to other Power Cases not too bulky and fits comfortably in your hand. The material fässt pleasant to the touch and does not look cheap. The device provides easy a complete load in an empty Iphone 5c. The only slight drawback: it is only the battery is charged, then the Iphone. If you want the other way around, you have to switch to charging mode the battery Always. I would have personally default rather the other way around (only Iphone and when the battery is fully then) but that's a matter of taste. The unit is now two weeks without problems in use for a longer period I can not judge.
