Cell phones can prove highly useful on the horse trail, as long as you have a signal and battery power. We can’t do much about the former, but the Sidewinder cell phone charger offers a way to guarantee the latter, even when you’re away from civilization for extended periods. This compact, 2½-ounce cell phone charger sports a tiny crank that, when turned for two minutes, generates enough power for six minutes of talk time or 30 minutes of standby time. It also powers an LED light. The Sidewinder comes with a cable, four adapter tips, and a handy carrying case.

Cost: $24.95.
