Soft silicone outer layer for a more comfortable feel and durable protection

Unlike other battery cases, the PowerSkin for iPhone 4 is designed with form and function on equal footing. The soft outer layer is made from a durable silicone rubber to provide a comfortable hold and extra grip, as well as offering premium protection against shocks, drops and knocks.

2000mAh integrated battery gives you up to 100% more power from your phone

Built-in to the case is a 2000mAh battery. This provides up to 480 mins of talk time or 350 hours of standby, which when coupled with the iPhone 4's own battery provides more than twice the power.

LED battery status lights let you know current charge capacity at a glance

On the back of the case are a series of four LED status indicators that light up at the push of a button to tell you the current charge left in the extended battery case. They also flash to indicate when the case is being charged via micro USB cable or through a mains/car USB charger (not included).

Smart battery technology ensures safe charging of your phone

Using the patented XPAL Power battery technology, this case will last for thousands of recharge cycles without noticable loss in capacity. The smart battery technology knows the charge the phone first and the case second, so if you just need a quick boost of power before going out, you don't have to wait for the phone to be charged through the case.

Made for iPhone 4

This extended battery case is designed to be used with the iPhone 4 mobile phone, so will be a perfect fit with flawless compatibility. There is an optically engineered camera lens window on the back that will not interfere with the camera while eliminating flash glare from the skin's surface. All buttons are accessible through the case, so you don't lose any functionality by keeping your Apple smartphone in the PowerSkin.
