The FRX3 is a solar and hand turbine powered AM, FM, weather radio with alarm clock. There is a built-in USB smart phone charger that allows a 30 second emergency phone call with one minute of cranking. To listen to personal tunes, use the AUX-input to play an external MP3 player. You’ll never be left in the dark thanks to the LED flashlight and glow-in-the-dark locater around the rim of the solar panel.
