I have a mobile charger that came with my car. Different pigtails let it plug into common plugs. I have a pigtail for 120V, 14-50 240V, and a NEMA 6-50 240V. The 6-50 is what I use for charging at my shop in MT because that's what I had for my welder. I typically set the car to use no more than 14 Amps, so any of the 240V plugs are overkill. I did install a Tesla Wall connector in my Garage here in AZ even though I have 240V plugs in the garage for my welder.
