This peripheral houses a rechargeable lithium polymer battery within an ergonomic, comfort-grip case with a soft-touch, non-slip finish.

According to mStation, the added “juice” gives consumers up to an additional 250 hours of standby time, 8 hours of talk time, 6 hours of internet use, 7 hours of video playback, and 24 hours of audio playback. It also integrates a 4 LED ‘charge status’ indicator and its own 30-pin dock connector, making it incredibly simple to recharge your juice pack using standard iPhone accessories, like the cable included with your iPhone.

The Mophie juice pack is available now for $99.95.
