The Keystone ECO Holster combines a handy external back up battery with a holster style case for iPhone 3G and 3GS. Slide the phone into the holster to store your iPhone when not in use, and benefit from the integrated charger which can provide a full charge in under 3 hours.
A mechanical spring sliding action enables users to quickly access their phone from the case and charger while leaving the bulk of the external battery behind. Double the battery duration of your phone with the additional 1300 mAh integrated case, without losing the sleek design and form of the iPhone 3G or 3GS.
The slim polycarbonate case securely attaches to belts, bags or briefcases.
The Keystone ECO Holster for iPhone 3G and 3GS is easily charged via USB cable, included in the package.
