Incase has introduced its new Power Slider case for the iPhone 3G. Based on the company’s previous Slider Case, the Power Slider features an integrated lithium-ion polymer battery to provide added power to the iPhone. According to the company, the Power Slider can provide up to 330 hours of standby time, 26 hours of audio playback, up to 5 hours of 3G talk time or 10 hours over EDGE, up to 7 hours of video playback, and up to 5 hours of Internet use over 3G or 6 hours over Wi-Fi. When connected, power drains first from the Power Slider to help preserve the device’s internal battery, and a five-light LED indicator on the rear shows battery status and also shows when the case is in sync mode or charging. Included in the package is a custom USB 2.2 cable that allows for high capacity charging and data exchange. Incase’s Power Slider for iPhone 3G will be available this holiday season and will sell for $100.
