Prong PWR Case
If there's one thing our iPhones really, really need — besides a decent signal or Wi-Fi — it's power. As a result, there are tons of battery cases out there, but they all share a common problem: they still need a separate charger. Enter the Prong PWR Case. This multi-function case features a detachable battery good for one complete recharge, plus integrated charging prongs built into the back, so you never need to worry about a charger. And in the event that you've run your phone and the battery dead yet still need to use your phone, there's a backup Micro USB port so you can charge and talk at the same time.
