The Partner Blaster is rated at 120,000 BTU, and the Power Stove is rated at 65,000 BTU. No wonder the Blaster is noisy! No doubt, 65,000 BTUs will get the job done, though--just will take more time.
I use a cast iron thing called King Cooker (not the same product as King Kooker), which has served me well for several decades. I think that the King Cooker is rated at 100,000 BTUs. It is a low-pressure burner, so it is quiet. It is heavy and bulky, but quite stable with a big tub of water. It also has a low-heat burner that we use with a giant wok.
