Battery life seems to be one of the most restrictive features of a smartphone today, so anything we can do to extend the juice is much appreciated.
The Mophie Juice Pack Pro is an iPhone 4 / 4S case that does just that, capable of more than doubling the life with its 2,500mAh battery. But battery power alone isn’t what makes it deserving of the “Pro” tag. The case also features a military-grade design with protection from rain, sand, dust, impact and shock – perfect for you adventurers.
There’s also an included belt clip, keeping your phone attached securely on your hip.
