Energizer AP1201 iPhone 4 case will make you forget the saying ‘never enough battery life’. It’s a slim protective case of silicone rubber, it has a quite nice look and it charges your phone while it’s on the device. The maker promises to double the life of your iPhone and it’s available for $69.99.
I like the concept of protecting and charging the iPhone at the same time. The case also doesn’t look bulky at all and it looks very stylish.
