In 2010, BioLite launched a really impressive backpacking gadget, the CampStove. It caught a lot of attention for its ability to not only cook food by smokelessly burning wood via a fan system but also because it could charge and power electronics with a thermoelectric generator. It was a cool system with technology that worked well.
The CampStove 2 takes the great foundation built by the original CampStove and builds off of it to offer even more electricity generation and an onboard battery. The same sized fire in the CampStove 2 now generates about twice the power and once the flame has gone out a 2,600 mAh battery will allow you to continue to reap the benefits of the system. You can add a Biolite CampStove 2 to your backpack for $130.
