When your outdoor adventures take you off the grid, you need a device that can fill multiple needs. The Etón FR500 is a compact unit that you can toss in your rucksack and take anywhere. It functions as an AM, FM, and shortwave radio with NOAA weatherband. It also has a flashlight, an emergency beacon, and an emergency siren. Plus, you can use it to charge your cell phone or MP3 player. This little wonder can be powered with the hand crank, or solely by the sun—solar panels make this a very “green” device. Of course, battery power and AC power are also options.
