New Device Allows Users to Charge iPods by Going for a Walk

January 11th, 2009 by  


Tremont Electric has launched a portable energy generator that allows users to charge handheld electronic devices simply by going for a walk.

The nPower PEG, launched at last week’s 2009 CES event, works on the principle of electromagnetic induction to create a 100% renewable energy source for everything from iPods to mobile phones. To get a charge, users simply connect the PEG to their mobile device and lay it vertically, either against their hip, or in a bag, while they go for a walk or a run.

At around 9 inches long and weighing in at 9 ounces, the PEG is portable and convenient enough to be carried anywhere, while also delivering a charge at the same rate as a wall charger. According to Tremont,  this equates to around an 80% charge from an hour-long walk for most mobile devices.

The Npower PEG is also totally recyclable, and could be a useful purchase for people traveling off the beaten track that need a reliable source of energy when the mains supply isn’t available. Alternatively, it could just be a nifty, and simple, way to reduce your carbon footprint.

The PEG will soon be available for pre-order at a cost of $149. At the moment, this is just a little too expensive to make perfect financial sense. However, it’s quite possible that potential buyers will be tempted if the price comes down over time, thus shortening the ‘pay-back’ period through reduced energy costs.
