I have 2 of these hand cranked portable heaters. One needs repair to the crank handle. When I was flying Alaska years ago I had a similar one and loved it when out away from electricity. Even the propane heaters pull power from your battery. These heaters warm you while warming your equipment. They burn regular gas and you can fill them right from the fuel tank low point drains. I have them here in Anchorage, Sold as a pair.
