The PWR Case is a charging case, designed for iPhones, that somehow manages to stand out in an increasingly saturated market of phone cases with built-in batteries. What's unique about this particular case is that it is fitted with folding prongs that allow users to plug the case into any outlet, getting rid of the need for charging cables even though users still have the option of charging with a USB cable.
Another awesome feature of the PWR case -- which somehow isn't seen on most battery-equipped phone cases -- is that you can detach the battery section of the case. This means you can use the case strictly as a case, but have the option of attaching the battery compartment in case you need to juice things up.
All in all, the PWR case brings a high degree of comfort and convenience to iPhone users.
