It is not even necessary to have a stove at all.
All you need to do is dig a small trench in the ground. About 18” long and maybe 8” deep and 6” wide. Put a steel grate over it and use pieces of wood to build a fire in the pit.
After it burns down a bit just do your cooking on the grate. If you have a pan, it is not necessary to burn the wood down too much.
If you are cooking directly on the grate, let the fire burn down to coals before putting the grate down.
I have done this while camping in the woods and it works about as well as anything.
Cooking over coals works best with cast iron cookware.
I sometimes fry eggs for breakfast by placing a cast iron fry pan right on the coals of my BBQ.
(Of course, cast iron would not be the best to carry for anyone backpacking)
Cool. Where do you plug in the USB?
Dig 4 trenches... N,S, E and W that way no matter which way the wind is blowing you are covered... oh and have a Rock to cover your trench and a couple more to hold your pot (to make it like a rocket stove)
Seriously we did this in Boy Scouts... it was an Indian thing we learned (not a Rocket Stove, but close) pretty basic prairie camping and very efficient... (we didn’t have access to the buffalo droppings for fuel, cowpies and grass is all we had to work with)
