Electric space heaters

I have an upright fan operated electric that I take in case I have power. Works great. Has a built in thermostat and tip over safety feature. Is small as it stands up and can really put out the heat when you need it. I usually run the electric and propane when I stop for the night and I have power to warm up the camper, then I turn the propane down low in case the electric goes out during the night.

I also have a cat heater and will use that when I am awake and I do not have power and then turn it off when I sleep and use the propane. I know it is safe but feel better safe than sorry.
