The Mophie Juice Pack Pro is a new iPhone battery pack/case that offers up to 150 percent extra battery life. The case more than doubles the battery life of the iPhone 4/4S, while protecting it from everyday hazards.
The charge of the case is indicated by four small LED lights. In addition to boosting your phone's battery life, the Juice Pack Pro is designed to protect your smartphone against whatever life throws at you. The case is resistant to water splashes, sand, dust, vibration and the shock and impact from falls. The battery pack also comes with a belt clip, making it easily one of the manliest iPhone power packs on the market today. Mophie's new power pack is out now and is priced at $150.
