Product information

Get the most out of your iPhone 4/4S with the Mophie Juice Pack Air. This award-winning, durable, ultra-thin case houses a rechargeable battery that virtually doubles your time to talk, surf and send, while protecting your iPhone from everyday wear and tear.

With the juice pack protecting and charging your iPhone, you can enjoy up to 36 extra hours of audio, nine extra hours of video playback and 6 hours extra talk time , all in addition to the battery life of your iPhone.

The sleek, hard shell case still allows full access to all buttons and ports and it doesn’t muffle the speaker. The standby switch allows you to choose when you want your juice pack to charge and the LED indicator lights at the bottom lets you know how much juice is left in the pack.

To charge the juice pack you can plug it into any USB charger or port on your computer.
