On the one hand you have a protective cover for his iPhone and secondly charges the iPhone with the bowl at least once on.
The battery pack is very good and accurately processed. Inside it's a bit softer designed so that the iPhone would collect no scratches or the like.
That you can use the shell as a pedestal is another great asset and to use from time to time in everyday life.
The pack is charged when it is empty the USB port from the computer or to an existing power supply to the power outlet.
All in all, a strong buy recommendation for all Apple lovers ;-)
