This little stove is powered by either a 16.4 oz. or a 14.1 oz. disposable propane cylinder (not included) and will burn for 3 1/2 hours at the highest setting. Just the thing to have on hand when the power goes out and you get tired of eating canned salmon for dinner. It costs $23.89 at Amazon.com.

One caveat: I'm advised by my husband, who was in the propane industry for 24 years, that propane appliances powered by cylinders should not be used indoors. Ask your local propane authority about proper usage.
