The Rover is a compact and multi-functional radio that is perfect for emergencies but stylish enough to use every day. The aluminum hand crank charges the internal lithium-ion battery to power its features: AM/FM and 7 NOAA Weather stations and a powerful LED flashlight. The direct USB transfer technology allows you to charge a cell phone or any electronic device via USB by simply plugging it in. Tired of cranking? Plug the Rover into a laptop or DC via mini-USB (included) to store energy so it's ready for anything. Dimensions: 2.625"W x 5.625"H x 2.125"D. Wt: 12.2 oz.
