Short answer
Buy the plug your car has. Home Level 2 charging works the same on both, at the same power, so a NACS charger is no faster than a J1772 one. If every car you charge has a NACS port, as every Tesla and most new models from 2025 do, get NACS; if you charge a J1772 car, or one of each, get J1772 or a unit that covers both.
The question comes up because the plug is changing: automakers are moving new models to NACS while J1772 cars, and the J1772 chargers already on garage walls, stay in use for years. Below: what each plug is, why the choice matters less at home than it seems, which adapters are safe for daily charging, and how to cover a household with one of each. Every charger mentioned is in our Level 2 (J1772) charger comparison or our Tesla and NACS charger comparison.
NACS and J1772 in plain words
J1772 is the SAE standard plug for AC charging that non-Tesla electric cars and plug-in hybrids in North America have used for Level 1 and Level 2. NACS, the North American Charging Standard, is the connector Tesla designed, renamed NACS in 2022. SAE published it as J3400, first as a technical report in December 2023, and it carries Level 1, Level 2 and DC fast charging on the same pins. The Joint Office of Energy and Transportation notes that most automakers committed to J3400 ports from 2025. On spec sheets you will see the NACS plug called NACS, J3400 or simply Tesla.
At home, only the plug changes
A home Level 2 charger delivers AC power, and how fast your car fills depends on the charger’s current setting and on the car’s onboard charger, as Tesla’s Wall Connector manual puts it, not on the shape of the plug. The NACS versions of popular J1772 chargers show this. Grizzl-E’s Ultimate 48A gives 48 A on a 60 A circuit with either plug, Autel’s AC Lite Home gives 50 A on a 70 A circuit with either, the ChargePoint Home Flex has the same six settings up to 50 A in both versions, and Schneider’s installation guide covers both Schneider Charge models together, with the plug as the only difference it lists. Same circuit, same breaker, same charging time; only the cable changes.

Choose J1772 if you charge a car with a J1772 port, such as a 2026 Nissan Leaf.
See J1772Choose NACS (Tesla) if every car you charge has a NACS port, as Teslas and most new models from 2025 do.
See NACS (Tesla)Which port does your car have?
Look at the charge port or the owner’s manual rather than going by brand or year, because the switch is happening model by model:
- Teslas have NACS ports; Tesla’s Mobile Connector manual covers every Tesla except the original Roadster.
- Model-year switches: Rivian says the J1772 version of its portable charger fits 2022–2025 R1T and R1S models, while 2026 and later Rivians use the NACS version.
- Cars with two ports: the 2026 Nissan Leaf, as InsideEVs reported, uses its NACS port for DC fast charging only and its J1772 port for charging at home, so a Leaf owner needs a J1772 home charger.
Adapters: what works at home
Owners we read found that the adapter that came with their car was for DC fast charging only, so it won’t work with a home Level 2 charger. Adapters for AC charging are a separate product. Their safety standard is UL 2252, which covers adapters that change only the plug’s shape and keep the car and charger communicating; it became a joint US and Canadian standard on June 24, 2026, and the Joint Office points to it. Even a certified adapter has to be allowed by the charger’s maker, and the makers we track disagree:
- No adapters: Tesla’s Wall Connector manual allows none, and Schneider’s guide rules out a converter between cable and car on either version.
- Carmaker-supported only: FLO says its Home X6 isn’t meant for adapters other than those the vehicle maker supports, and its warranty excludes damage from adapters not made by a carmaker.
- Compatible adapters allowed: Autel says a NACS car can use its J1772 AC Lite Home 50A through a compatible J1772-to-NACS AC adapter, and Enphase says an adapter used with its IQ EV Charger 2 must be rated for, and compatible with, both the car and the charger.
- The maker’s own adapter: Leviton lists its own NACS adapter for its EV Series chargers; the Leviton we track is the EV40P.
Ignoring the manual can cost you. Owners we read report one Tesla Wall Connector that overheated repeatedly while charging a Ford through a third-party adapter and then failed, and another owner who was refused warranty help because a third-party adapter had been used.
Adapters: use only a car-side adapter your carmaker supplies or approves, or one certified to UL 2252 that both your car’s and your charger’s makers allow, and check that it is rated for AC charging. Never use one on a charger whose manual forbids it. Outlet adapters, splitters and extension cords between the charger and the wall are a different thing, and charger manuals forbid them.
Which plug to buy for your household
Only NACS cars: a NACS charger
If every car you charge has a NACS port, buy a charger with a NACS cable and skip adapters altogether. Tesla’s Wall Connector is NACS only, and several J1772 chargers come in NACS twins with the same install and settings: the ChargePoint Home Flex and Home Flex NACS, the Grizzl-E Ultimate 48A and Ultimate 48A NACS, the Autel AC Lite Home 50A and its NACS version, and Schneider Charge and Schneider Charge NACS. When we checked, the Grizzl-E cost the same with either plug on its US and Canadian stores. Our best Tesla and NACS home chargers ranks them.
Only J1772 cars: a J1772 charger
If you charge a J1772 car you plan to keep, including a 2026 Leaf, buy J1772. Should a NACS car arrive later, you have two routes: an AC adapter your carmaker supplies or approves, if your charger’s maker allows it, or a charger whose maker sells a NACS cable. ChargePoint sells a kit that swaps a J1772 Home Flex to a 23 ft NACS cable, and Enphase sells a NACS replacement cable for select IQ EV Charger 2 models. Our best home EV chargers covers the J1772 picks.
One of each: a charger that covers both
Tesla’s Universal Wall Connector is built for this: a 48 A hardwired unit with a NACS handle and a J1772 adapter that docks on the side, so a NACS car takes the handle as it is and a J1772 car takes it with the adapter on. Owners we read on Ford and Rivian forums report the adapter working well, while several in one Tesla forum thread report it sticking in the dock within about a year, worse outdoors in freezing weather. Another route is two cables on one unit: Grizzl-E sells its Duo Connect 40A with one J1772 and one NACS cable (the version we track has two J1772 cables).

Whichever plug you choose, the install doesn’t change: a licensed electrician sizes the circuit to the charger’s manual, under a permit where your local authority requires one, as our guide to getting a charger installed explains. In Canada, check the label for a Canadian certification mark; ESA requires one on chargers used in Ontario.
How we chose these
- Started from the cars a household charges and the plug each one has.
- Compared the manuals and spec sheets of the J1772 and NACS versions of the chargers we track, including what each maker says about adapters.
- Checked prices at the stores we can read in the US and Canada, and show the date we checked.
- Read owner forum posts for reported problems. The samples are small, and we say so.
What we don’t do: lab-test or install chargers, or give wiring instructions. Installation is a job for a licensed electrician, with a permit and inspection where your local authority requires one.
NACS or J1772 questions
Is a NACS home charger faster than a J1772 one?
No. At home both deliver Level 2 AC power, and the charging rate is set by the charger’s current setting and your car’s onboard charger. The NACS and J1772 versions of the same charger, such as the Grizzl-E Ultimate 48A or Autel AC Lite Home 50A, have identical output and circuit needs. NACS also carries DC fast charging, but that happens at public stations, not at home.
Should I buy a NACS charger to future-proof?
Only if your next car will have a NACS port. Most automakers committed to NACS ports from 2025, but a J1772 car you keep for years still needs J1772, and some new cars, such as the 2026 Nissan Leaf, charge at home through a J1772 port. Buy for the cars you will charge; a charger whose maker sells a NACS cable, or the Universal Wall Connector, keeps both options open.
Why won’t the adapter that came with my car work on my home charger?
Most likely it is a DC fast-charging adapter. Owners we read found that the adapter supplied with their car worked only at DC fast chargers, which a home Level 2 charger is not. Home AC charging through the other plug needs an AC adapter your carmaker supplies or approves, or one certified to UL 2252, and your charger’s maker has to allow it.
Can I charge a NACS car on a J1772 charger every day?
Yes, if the adapter is the right kind and both makers allow it. Use one your carmaker supplies or approves, or one certified to UL 2252, and check the charger’s manual: Autel and Enphase allow suitable adapters, FLO only carmaker-supported ones, and Schneider none. If the manual says no, a NACS twin of the same charger avoids the question.
Does a NACS charger need a different installation?
No. The NACS and J1772 versions of the chargers we track use the same circuit and breaker for each setting: 48 A on a 60 A breaker for the Grizzl-E Ultimate 48A, 50 A on a 70 A breaker for the Autel AC Lite. A licensed electrician installs either one to the manual, with a permit and inspection where your local authority requires one.
