Running around town or running to catch a plane, there's one thing you don't need — a smartphone with a depleted battery. Good luck finding an open outlet to recharge your phone in an airport, store, or city street! Enter the mophie juice pack. This protective case features a built-in battery with enough power to keep your Samsung Galaxy S III going for hours after its battery has run out.
Slip your Galaxy S III onto the juice pack connector and close the case. It's now connected to a built-in rechargeable battery that can greatly increase your reserve of power — enough for up to 9 additional hours of talk or Internet use, or up to 32 more hours of audio playback. You can set the juice pack to keep your smartphone continuously charged, or with a button press recharge it all at once.
An all-access case
The juice pack has a USB charging cable that can connect to a computer or USB-compatible power adapter. And good news — you can sync your Galaxy S III through the air's charging cable. Integrated pass-through buttons let you control volume, mute, and power on/off.
