Technocel on Tuesday introduced two new products for its line of portable batteries and in-home chargers: the PowerPak XT and PowerPak Duo. Both devices are re-designed versions of the previously released PowerPak, and offer larger batteries. By using the interchangeable tips they are said to support roughly 95 percent of available handheld USB devices, along with any standard USB cable included with most wireless products. Each portable battery also features built-in LED indicator lights for displaying the amount of remaining power.
