You just invested in the iPhone 5, and you want to make sure you're always juiced up while you're on the run. This 2300mAh built-in battery can provide a true 100% boost, equaling an additional 10 hours talk time. It also features 1A powerful output, integrated charging switch, and battery level LED indicators. Coupled with the included bonus screen protector and protective lip that goes above the screen, the protection offered by this case will never be compromised. It transforms the charging port from Apple Lightning into a commonly seen Micro USB port, which you can use to easily sync or charge the iPhone using the included USB cable.
