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. This is how it works It’s basically physics: a blads that protrudes from the device is placed directly into the flame and this absorbs thermal energy. This thermal energy is transferred to a generator kept cool by a small water reservoir. The difference in temperature is enough to create enough electricity to charge any small device. Again, you should note that this won’t charge your phone as fast as your charger and it’s not meant for everyday use. But when all you have is a burning flame and your power-bank is dead, this might be a life saver for campers. You can purchase Flamestower USB Fore Charger on Amazon for only $99.
