Tremont Electric has developed the nPower® PEG (Personal Energy Generator), a small, lightweight device that recharges your hand-held electronics from the kinetic energy you generate while walking, running, or biking. Slip it in your backpack, briefcase, or purse and go about your daily activities. As you move, your PEG will continuously top-off its internal battery providing you with extra power when you need it, while you’re on the go. And in an emergency, shaking your PEG will give you the ability to call for help. Durable polycarbonate frame and titanium casing, adaptive control system that automatically adjusts to your activity to capture maximum power, recyclable lithium polymer battery stores energy for up to a year, and USB 2.0 interface and universal iGo tip system let you use the PEG with over 3,000 hand-held devices. $149.99.
