Picked up a 2KW diesel heater for the Jeep.
Made a portable “suitcase” heater for the moment of tent camping.
Running on 18v ryobi batteries, with a 24v to 12v step down transformer (ryobi measured ~22v, 12.8v after step down)
The 6AH lithium lasted most the night on low.
Figure 6AH @ 18v = 108WH = 9AH @ 12v
Draw is just shy of 1A on low, near 8A on first start.
Any chance you’d do a full write up with parts list on this? It’s dang cool!!
What kind of temp were you camping in?
Utah vs Socal winter camping is probably pretty different.....
