You wouldn’t think exothermic reactions would be the next big thing in charging your phone. But since there’s an endless stream of creativity in the way phone chargers’ executions are developed, this new campfire charger seems almost logical.

The FlameStower literally goes where no phone charger has gone before – into fire. Basically a USB device, one end is placed directly into a campfire and the other connects to your cell phone. While it might not seem very practical, the idea is that a campfire is a multitasker, allowing you to now charge your phone while you cook dinner – just don’t use it in your home.
