Looked it up. I found a $2000 Honda portable generator is rated for 1800w, and can run at that power output for 3.2 hrs on one, one gallon tank. Standard Model 3 take 50,000 w to charge fully, so you'd need to run it for 28 hours to charge the battery, and use 8.6 gal of fuel. That 28 hours of charging will get you 220 miles, giving you about 25.6 mpg.
