If you need a power source when you are camping you might want to consider the PowerPot by Power Practical, winner of the Inventor of the Year Award at the 2012 DaVinci Inventor Showcase. The PowerPot turns heat into useful electricity. It will power lights so you can see what you’re cooking, recharge a cellphone, or run a little Bach while you’re contemplating the flames (or really whatever music you’re into).
