Weighing approximately 1.5 pounds, the Eton FR400 is cited as affordable at $59.99, the same price as the Eton FR350. However, whereas the Eton FR350 supports SW frequency, the FR 400 is geared primarily towards WX and FMNOAA frequency, allowing users to keep a constant tab on potentially dangerous weather that may be approaching. The Eton FR400 also features an emergency siren, a built-in cell-phone charger, and a rechargeable Ni-MH battery that can be powered for one hour by 90 swift turns of the FR400’s crank.
