I need to charge a few times a month at a location where the only 240V outlet is in the laundry room just inside of the garage. I'd like to keep the door closed to keep out critters, and also hot/cold air. The only thing I can think of is a small pet door at waist level with a sliding cover that can be put in place when not in use. Anyone have a better idea? Putting an outlet in the garage is not an option.
