The fire has been around for about 800,000 or a million years, revolutionizing life for cavemen. Nowadays, the Bio-Lite Camp Stove ($130) is changing the game for the modern caveman.

This clever portable stove is the size of a water container, so it is easy to pack without losing storage space. To put it to work, simply throw a handful of small pieces of wood bark or tree branches in the cylinder and light it up.

The Camp Stove will convert the heat into energy, so you can use it to power your USB devices. And while you’re waiting for the gadgets to get juiced-up, you can prepare yourself a warm meal. Now that’s multi-tasking!
