FlameStower Charger: Charge USB Devices with Fire

Solar chargers are quite handy when you are outdoors and don’t have access to a conventional electrical outlet. But what if you want to charge your gadgets at night? The FlameStower Charger can help. It is a handy tool that lets you charge smartphones, cameras, and flashlights with fire. Any fire source, including a camp stove or campfire, will work. The FlameStower outputs 2.5 average watts of power to charge your phone.

The device has a portable design and captures excess heat from campfires to charge your devices (thanks to its Thermoelectric Generator). Just unfold the legs, fill the reservoir with water, and place the blade in fire. For every minute of charge time, you could get about two minutes of talk time.
