If I didn't already own one, I would join this drop in a heartbeat. The BioLite is an awesome little stove that can be fueled from any forest floor.
Perfect for camping expeditions, and picnics when trying to pack small and light.
Fairly lightweight, and compact. The grill ads some bulk, but is really awesome. Can easily cook for 3-4 people at a time.
Charging does take a bit of time, but is still effective.
