I have a camp stove about the size of a side burner. I suspect it's around 10,000 BTU. I use for mashing, if I'm doing a step mash, but I heat the strike water on the turkey burner.
Your results may very. Test it with a pot of water. If it can reach & hold a rolling boil, use it. If it falls over, hopefully it will before the water is too hot.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
