For operation, there is nothing to do except plugging in the battery. He was immediately detected and charging starts. Moreover, there are no buttons on it.
Side with the announced capacity 3600 mAh I make more than two refills my iPhone 5. The full charge is doing more or less 1:30.
It is also compatible with a sports camera.
Finally, it's high but there is a cover that comes with practice but is not big enough, it takes a little force to turn the phone cable and touch the battery is pretty nice.
Very good accessory that comes in handy for long days or a phone whose battery begins to weaken.
