I have not tried or felt the need to try to increase its output. I think much more output would get the walls too hot. I don’t even use the stove on high because it’s so close to the walls. It’s fine for warming soup and boiling water for coffee, and does scrambled eggs well with the right pan. I would have been fine with a single burner or even a portable butane stove, but my wife wanted the full interior. Most other stuff I prefer to cook outside anyway to avoid smelling up the camper both for my own nose and for bear safety.
