While you can get a few thousand BTUs from a propane heater (perhaps 5,000) you can only get 500 from 12 volts and that's just theory, in actually, with the gauge of wire that is in a cart you'll get 200 tops.
With USB you'll get ten.
Now, if you have an electric cart with massive battery reserves and voltage above 12 volts and are willing to add some heavy gauge wires in, that's a different story.
If you change your mind on propane, I have one. I got it with a cart that I sold off $35.00

I'm interested in the heater if it's still available for $35.
