Several years ago I could not figure out what was going on in the next camp site. Some guy kept gathering twigs off the ground to put in some thing that had small flames coming out the top, did that for over an hour.
It was later that I heard that there was some gizmo that converts fire heat to USB power.
Now, looks like you found the next generation, instead of being a wood fueled stove, it uses heat from some other source to power a USB.
I would not buy it but I have a dynohub and a couple small solar panels so my opinion is based on what I already use, your opinion could vary.
