How about butane? If you do a search on Amazon for "butane stove you'll find a bbunch and they all look the same. I have the GAS ONE Stainless Steel Portable Gas Stove and have used it during a couple power outages. Worked great. Iwatani has a few listed that seem to be higher end but still with the same basic design. Apparently they have more BTU power but they're more spendy too. No affiliation with either company.
