Question about a burner

Hey all. I was checking out my local sporting goods store when I saw a 2 burner camp stove made by Camp Chef for $89. The only problem was it is only 30,000 BTUs per burner. I have 2 keggles and mostly brew 5 gallon batches but would consider 10 eventually. Is this burner going to be completely useless for brewing or would it be adequate? If it isn't adequate does anyone have any 2 burner stoves that have worked well for them? Thanks guys.

Would your keggles even fit on a camp stove? I've got a one burner that I use to keep my sparge water hot, but I couldn't put my kettle on it.
