We just had a power failure due to an unusually windy day at about 4:00 pm.  Since we were having 10 over for dinner, we got out our Coleman Powerhouse stove and cooked the meal outside without any problems.  (We ended up eating by candle light but that turned out to be fun.)  The stove worked flawlessly on Coleman fuel.  I haven't tried gasoline yet.  I must admit that the metal housing is thin and flimsy and should be improved.  That said, it sure is great to have a stove like this for emergencies.
