From mobile phones to GPS receivers and mp3 players, electronic gadgets entertain us and keep us safe when we hit the backcountry. The problem, of course, is that the backcountry doesn’t come with power strips, and electronic gadgets can quickly become paperweights if we don’t figure out some way to recharge their batteries. For all electronic devices, there are basically four options:
- Replace the discharged battery with a fresh one
- Use an external battery pack to recharge the battery
- Use solar power to recharge the battery
- Use wind power to recharge the battery
