I have a power inverter in my truck that I run a coffee pot off of when I am camping, I am not patient enough in the morning to make a fire to perk coffee, anywho. I think it was like $80 at Tractor supply and doesn't take up too much space although it is not something to run from a cig lighter, it is hard wired into the truck, I have found that I use it a lot more than I ever thought I would, Cameras laptops flash light charger, they really are useful.
Not the same as mine but you get the idea
