Now charge your phone right there at the campfire - as you boil water.

This unique 'camping stove pot' is more than a way to boil water. It contains a lightweight thermoelectric generator that converts heat into DC electrical power. In other words when you’re boiling water for tea or coffee, you can be charging your cell phone or other USB device at the same time. Just add cold water to the pot and place it on the campfire or even a stove, and the PowerPot will start powering up your mobile electronics. It comes equipped with a standard USB (5V) port, making it compatible most devices you already own. So your device is safely away from the heat, it comes with three feet of heavy-duty, flame-resistant wire. The built-in solid-state voltage regulator provides up to 5W of power to charge your high-tech devices. I tried the PowerPot on my stove at home. In about 10 seconds the green charging light lit. I plugged in my Galaxy S4 phone and it immediately went into charging mode. So this is not only good for use on a camping trip, but also during a power outage at home. (Assuming you don’t have an electric stove.) The company says their PowerPot will charge cell phones, GPS units, iPods, and lithium ion batteries or will run speakers, lights, fans, or other low-power USB appliances. (Remember we’re talking USB, not AC.) $149.00
