Electrical outlets are few and far between when you're out in the wild, and lugging a generator into the jungle isn't always practical.

One nifty little alternative power source is the wind-up cell phone charger. Wind a small hand crank to create kinetic energy. Wind-up chargers store up kinetic energy and convert it usable power. Similarly, rechargeable kinetic batteries are under development. Design engineers Yeon Kyeong Hwang and Mieong Ho Kang have proposed a rechargeable AA battery design that uses a spring and a twisting action to charge a Ni-mH battery, and Brother is researching technology that would utilize a shaking action to recharge batteries [sources: Yankodesign, Samaniego].

Until kinetic rechargeable batteries become commercially available, you can invest in a battery or solar-powered USB charger. If you are so inclined, you can even make your own from a kit such as the MintyBoost. Before purchasing or building a battery powered USB charger, be sure to check whether it will work for the device you want to power.
