Extended Battery Life: Since it is designed to extend the battery life of your Galaxy S III by up to 100%, the Mophie Juice Pack is the ultimate Galaxy S III battery case for travel or business. The Juice Pack is great for when your Galaxy S III is drained of power or you simply one to extend its battery.

Rechargeable Battery: The Mophie Juice Pack features a rechargeable lithium-polymer battery rated at 2300mAh. The Mophie Juice Pack battery can easily be recharged by connecting the Juice Pack to a power source using the included micro-USB cable. The USB cable can be plugged in to your computer or any wall-plug style power source with USB output. You can either charge the Juice Pack with the Galaxy S III inserted or charge them separately. The Juice Pack comes charged and ready to go, but after the initial use, normal charging will take only 2 to 3 hours for maximum power.

Sync & NFC Compatible: You can sync your Galaxy S III to Google Play without removing it from its Mophie Juice Pack via the included micro-USB cable. The Juice Pack will also charge while connected to your computer and syncing. The Mophie Juice Pack is also completely S Beam and NFC compatible, so don't worry about the protective case getting in the way of sharing with your friends.

Standby Mode: The integrated power switch allows you to put the Juice Pack in standby mode, so you only use the battery when you need it. In standby mode, the Juice Pack still allows charge and sync capabilities through the micro-USB port and still offers the complete protection of a case.

4 LEDs: Four LEDs on the bottom of the smart battery case keep tabs on how much power is left in the Juice Pack battery. The LEDs also keep you updated on the Juice Pack charging status when it's plugged in. The LEDs located on the back of the device will blink when charging. As the Juice Pack becomes more charged, the LEDs will indicate how full it is, but one LED will remain blinking until completely full. To check the battery status of the Juice Pack , press the button located on the bottom of the case. When pressed, the LED lights will illuminate for several seconds. Four LEDs means that the Juice Pack is fully charged, and one LED means that it is almost empty.

Protection Circuitry: The Mophie Juice Pack features built-in short circuit, over-charge, and temperature protection.
