The powerchimp is a handy emergency charger for iPhone 4/4S, BlackBerry, other smartphones (including HTC & Samsung) and iPods.
Giving a 30% recharge on smartphones and a 50% recharge on iPods, the powerchimp lite houses 2 x AA batteries in a tough, compact shell and comes complete with adaptors for the most popular phones.
To charge your gadget, insert 2 x AA batteries (compatible with all AA batteries), open the rubber cover at the top, connect charging cable, attach the required tip and connect to your device. Then press the On/Off button. The LED will be red, indicating that it's charging your device.
The powerchimp also features a useful flashlight which is activated simply by pressing the On/Off button when the charging cable is not attached. Once you plug the charging cable in, the flashlight is disabled - genius!
