Solar radio. A compact sized radio that can be tuned to AM and FM stations; the built-in rechargeable battery is charged using electricity generated by the solar panel. It is useful for accessing information at those times when the situation warrants it. Even in environments where charging the item using solar power is difficult, it can be charged from a USB power source, making it handy for daily use. Comes with an automatic channel tuning function (autoscan). Three AM stations and three FM stations can be programmed into the memory of this radio.
