I'm only half kidding. I'm a bit of a prepper and I have lots of powerbanks and devices that charge from USB but besides idling my truck I really had no other way to charge any of them in case of a long-term power outage which seemed a bit of an oversight on my part.

Not like this solves the issue. 30 watts (under ideal conditions) isn't much but it's a start.

I looked up haybox cookers, seems like a neat idea to insulate already boiling water, but a wood fire doesn't seem like the most convenient or efficient choice if what you want is to efficiently heat something up a specific amount but no more.

Just light a small fire and keep it pretty small and it can burn out once you are done.

I use a Kelly kettle stove a lot, tiny fire but still a few thousand watts of thermal energy. A few sticks at a time as fuel.
