The wall unit delivers 48 A (11.5 kW) hardwired on a 60 A circuit, or 40 A (9.6 kW) on a 14-50; your car's onboard charger caps what it actually accepts. Most non-Tesla EVs built before 2025 have a J1772 port; a NACS car takes the wall charger's NACS version. The portable unit plugs into an existing 14-50 outlet on a 50 A circuit with no install. It is J1772-only.
