If you go camping all the time, this nifty gadget is exactly what you need to keep connected when you’re out there in the woods with only your campfire to keep your warm. When an electricity outlet is nowhere around and your power-bank has run out of juice, as long as you can start a fire, converting that heat energy to electricity is possible with this $100 FlameStower Charger.
This isn’t meant to charge just your phone, it will charge any small device with a micro-USB port. However, you should note that it won’t charge your phone as fast as your regular adaptor but it still works. At least, it’s better than absolutely nothing at all.
