Mophie Juice Pack Helium Blue Charging Case - iPhone 5/5s

The Juice Pack Helium™ is a rechargeable 1500mAh lithium-ion polymer battery and protective case in one.

Nearly twice the battery life of the iPhone 5/5s – up to 5 hours of talk time on 4G and LTE, up to 6 more hours on 3G, up to 30 hours of additional audio playback, and up to an additional 7 hours of video playback.
Soft-touch finish – sleek polycarbonate ABS materials in a soft-touch design.
Quick 1-amp recharging speed.
4-LED status indicator tells you how much "juice" you have left in the case for charging.
USB charger with included microUSB cable allows you to charge your iPhone 5/5s and case simultaneously, without needing to remove the iPhone 5/5s from the case.
Open ports at the bottom and front of the case act as an actual speaker box, redirecting sound from the bottom of the iPhone to the front, resulting in richer, fuller sound.
