The mophie juice pack plus for Samsung Galaxy S III is a battery pack housed within a protective case with a soft-touch matte black finish. The two-piece slider case allows access to all the controls on your phone and doesn't interfere with the ports, buttons, speakers, camera or flash. It also doesn't interfere with your phone's NFC or S Beam capability so you can continue sharing through touch. A handy switch allows you to toggle back and forth between standby and charging modes. Four LEDs on the bottom let you keep tabs on how much power is left in the juice pack battery. They'll also let you know when your juice pack is charging. Additionally, a micro USB cable is included for charging.
