Lots of us have so much energy it seems like we don’t know what to do with it. The geniuses at nPower have devised a little gadget that helps us put our over-anxiousness to good use: the nPower Peg. This little device is a backup battery charger for hand held devices. As you walk, run, jog or even ride your bike, the movements from your body provide energy for its internal battery. If you are in a pinch and need battery life, just shake the heck out of it for a few moments and you will have enough power to make a phone call. Definitely a little device to keep an eye out for.
