Here’s a familiar scenario: You’ve spent most of your day tweeting, intagramming, and facebooking from your mobile. Just as you are about to meet up with friends you see that familiar flashing low battery warning. You need juice. But you are on the go. Enter the nPower PEG.

nPower PEG (Personal Energy Generator) for mobile devices is the world’s 1st human-powered charger for your hand-held electronic devices. Placed in your backpack, briefcase, or purse, the nPower® PEG harvests your kinetic energy as you walk, run, or bike, storing it for use wherever, whenever you need it. Now you can extend the use time of your cell phone, Mp3 player, GPS, and other devices without searching for a wall outlet.

 The 10.5-inch plastic cylinder weighs just under a pound, and contains a 2,000 mAh lithium battery. It draws its power from kinetic energy. Once filled, it holds a charge for around three months. Red and green LED lights alert you to the PEG’s charge level.

The nPower PEG retails for $129.
