Greetings & Welcome!
While I can’t answer your exact question, let me tell you about my preferences…
My criteria for my essentials is that they don’t require any electricity or battery power, only fuel. For many years I’ve used wick type kerosene heaters & cookers which also run on diesel. Recently, I have switched to cooking oil, which is more slightly more expensive, but lasts longer, is more eco friendly, and available at nearly any grocery store.
Then I have a heat powered wood stove fan to place on them to circulate the heat, without requiring any other power source other than the heat from the heater.
I bought my current gallon of cooking oil at Walmart for $4.58 at the beginning of last month, and I still have nearly half a gallon left, and I’m using it for heating, cooking, refrigeration, and hot water, and I’m up here in the the frozen north of Minneapolis.
I can give you more details if you’d like, and almost everything I’m using is cheap & dependable.
