In order to fulfill all of your powering needs, the Multi-Function Battery Charger provides a dual source of power: USB Power or AC Power. With the foldable power plug, you can plug the battery charger directly into any standard wall outlet and charge your battery - whether on the go, at home, or at work! With the use of a USB cable (not included), you can charge your battery directly through your computer's USB port! While in this mode, your new battery charger acts as a desktop battery charger. For added convenience, you can charge your battery while in the car with the use of an USB Car Adapter (not included).

If powering your battery wasn't enough, this product also allows you to power your Centro! With the use of the included charging cable, you can connect your phone directly to the Multi-Function Battery / Smartphone Charger while in "AC Power" mode and charge your battery AND your Centro at the same time!

Compatibility - The Multi-Function Battery/Smartphone Charger is compatible with both OEM and Seidio Batteries!

With the design of the interchangeable battery slots, this charger allows for multiple phone compatibility! For instance, if you use a Centro but your wife/husband uses a Blackberry, you can both use the same Multi-Function Battery/Smartphone Charger base. All you need to do is purchase the secondary phone's interchangeable battery slot/PDA Charging Cable separately. This universal design is what makes this product different from the rest!
