19kW is 80A@240V, which is just an absurd amount of power. Almost everyone will be fine with less than half that (9.6kW = 40A@240V, the max you are allowed to push continuously through a NEMA plug), and at least in the U.S. is the standard "EV-ready" plug: NEMA 14-50.
A lot of people will be just peachy with the 1500W of Level 1!
