Cranks up its usefulness in an emergency
If you're miles off the grid - or the whole power grid goes down altogether - you need this multi-function muscle-powered dynamo. 7 NOAA weather channels, LED flashlight and weather alert mode keep you safer in an emergency. 90 seconds of cranking charges the internal rechargeable battery long enough for 5-7 minutes of radio time, or 20 minutes of flashlight. Plus, there's a USB port for charging your cell phone or GPS. Charges by built-in solar panel, USB or 3 AAA batteries, too.
