I found this very easy to install. I am an aircraft electrician by trade. If you are not handy, then you might have a tough time on install. I put this heater in my 18 ft cargo trailer and powered it with the \"Ecoflow River 2\". Pretty sure any 12v deep cycle battery would power it no problem for days. Once it's started, it uses very very little 12v DC. It puts out a lot of heat. We camped 2.5 days. High of 40°f low 28°f used 2 gallons of diesel on lowest setting. Kept wife and 1 year old baby warm the whole time. The hardware is very cheap but for the price of this thing, I was very happy with it. Tip: never remove 12v power while it's running. When you press the power button, there is a shutdown cycle that must happen. When your battery dies or you disconnect the heater without proper shutdown cycle, it will flood/ foul and won't work the next time without needing disassemble.
