Once upon a time, it was perfectly acceptable to take a little time to escape and unwind in the wild, but if the thought of not having a way to communicate with the outside world in case of an emergency is threatening to ruin your camping trip, why not pick up a BioLite CampStove and rest easy?
The BioLite CampStove is a small device which burns rather efficiently using only small twigs. It maximizes efficiency by using a small bit of electricity to power a fan, which makes the fire burn better. While this is great for boiling water and cooking meals, the best part is that there is plenty of electricity left over to power your USB gadgets. The $129 price might seem expensive, but profits from these go toward a good cause. BioLite has been working to get their larger HomeStoves into homes that rely on open fires for cooking and heating. With 90% less smoke emissions, the people using them can lead healthier lives, and have the ability to charge electronics, when they might not have been able to, otherwise.
Sure beats running the car long enough to charge up the cell and definitely better for keeping the forest pristine.
