For all you restless souls who enjoy secluded areas, fire-walking, and virgin sacrifices, on the next trip to your local tribal village, you can at least enjoy one comfort of home by bringing along the Eton Boost Turbine 2000 ($59). Small enough to fit in your pocket, or hide under your loincloth, this magical little device delivers power to any mobile device that requires a USB port just by gyrating a hand turbine (And I bet you thought you’d never gyrate anything, again). So when you realize that becoming the village fire-king by using a zippo wasn’t such a great idea, because…you know…it runs out! At least you’ll know that your phone won’t.
