This backup battery charger is specially designed for iPhone 3G/3GS with a ultra-thin, light-weight, low-profile characters and as a rechargeable external battery concealed inside of a protective form-fitting case for the iPhone 3G & iPhone 3GS.
It offers you the full protection of a hard-shell case while providing virtually twice the battery life of the iPhone alone.
From the design and build quality perspective, anecoo juice bank is truly top notch.
The hard plastic shell is sturdy, it fits our iPhone 3G & 3GS, like a glove and it does not impede access to the volume rocker, power button and vibrate/ring switch.
On the bright side, there are four LED indicators on the rear that show the remaining power capacity with a simple button press, and activating the built-in battery is as simple as flipping a toggle switch on the unit's bottom.
Apple will never be perfect without our Juice pack.
