Getting caught without batteries or a place to plug in a recharger can be inconvenient or even dangerous. Etón’s FR160 radio is powered by a solar cell and can pick up AM, FM, and dedicated weather bands. It also offers a built-in flashlight. When the day darkens, turning a hand crank will recharge the $30 FR160’s battery; it can also charge a cell phone through a USB connection.
It is impractical to lug all the drinking water you will need on an extended camping trip. The $100 battery-powered SteriPen Journey allows you to purify two pints of water at a time in just 90 seconds by immersing a handheld ultraviolet light emitter in a bottle or other container. The light neutralizes microbes so they can’t reproduce and cause illness.
