Losing power doesn't have to mean losing touch with the rest of the world. This emergency radio needs only one of these three sources to operate: three AAA batteries, a little sunlight, or a small workout via a hand crank. Once the radio's running, you can set it to broadcast local weather alerts and still have enough juice to recharge your phone. And should you forget your candles and matches as you run to the basement for shelter, this phone-charging radio unit also serves triple-duty as an LED flashlight. Available on Amazon; $80.
