Prong’s PWR case for iPhone 5/5s features a detachable battery pack with an integrated plug
Prong has just unveiled its new PWR case for iPhone 5/5s that offers an “all-in-one” power solution. This case will allow you to simultaneously charge your iPhone and a detachable battery pack using its integrated wall adapter. When the backup battery is removed, the iPhone is left with a clean bumper for minimal protection against drops and dings.
