Here is something that will come in handy to all those New Yorker’s next time a hurricane hits the city. BoostTurbine2000 by Etón is a rechargeable backup battery pack for mobile devices that is charged by a hand crank generator. One minute of winding provides enough power for a 30 second phone call. When the pack is fully charged it can fully charge most smartphones.
