Charge at Home / Chargers and plugs
J1772 and NACS: which connector fits your car
Two plugs share North America. Adapters bridge them; match the adapter's rating to the charger.
Two AC charging connectors are in use on North American cars:
- J1772, the long-standing standard on most non-Tesla EVs.
- NACS, the North American Charging System that Tesla introduced, now standardized by SAE International as J3400. Many automakers have announced moves to this port.
For home charging the plug is a fit question, not a speed question: both carry Level 2 power.
If your car and charger do not match
Adapters exist in both directions. Use one that is rated for at least the current your charger delivers and that comes from the car's maker or a listed manufacturer. An adapter is one more connection carrying the full current for hours, so a cheap, unlisted adapter is the weak link.
Buying for the next car
If you expect to change cars in the next few years, consider a charger whose cable can be swapped, or one sold in both versions, so the wall unit outlives the car.
