The American Red Cross FRX is a solar and hand turbine powered AM, FM, weather radio with a USB smart phone charger. Its LED flashlight and glow-in-the-dark locater guarantees that you'll always have access to light. Aside from solar and crank power, the FRX has a DC-input (mini-USB) for AC power. This radio also gives the option for individual radio listening, via the headphone output. The FRX 3 adds a digital radio, alarm, AUX-input and display. They make great additions to any emergency preparedness kit. No plugs or wires required. The ARC Zone Guard offers the Weather Radio in a wired version for everyday use - before the power goes out. The Zone Guard + and + Modules pair together wirelessly to give you several points for listening throughout your house.
