A L1 EVSE has one lead connected to ground ( neutral). A device called Quick220 takes two AC outlets in opposing phases to generate 240VAC. It is limited in current due to the breakers. 16A is very doable with 20A breakers and nothing else on the circuits. Otherwise 12A fits into 15A circuit. 12A is the NEC recommended max for a 15A circuit.
