Of of the 4 I have, the hcalory toolbox all in one has the best setup. You can use the internal tank or pull from a 5 gallon Jerry can pretty easily. It goes on sale for $120-40 and comes with a 12v to 110v inverter plug. You can run directly off a power station.
You will have to use some heater vent for the intake though
