Home Level 2 chargers

Home charging is where the low numbers above come from, and Level 2 is what makes it practical for daily driving. 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.
