NACS vs. J1772: Which Plug Your Next Charger Should Have
North America is mid-changeover. The plug Tesla designed — now the SAE J3400 standard, still universally called NACS — is becoming the native port on new EVs, while the J1772 plug (with its CCS1 fast-charge extension) sits on most of the fleet already on the road. If you are buying a home charger today, you are really making one decision: which plug lives at the end of your cable for the next decade of cars. This page lays out what each connector is, exactly which 2025–2026 cars ship with which port — verified against manufacturer sources, because the aggregator lists on this topic are frequently wrong — and the adapter rules that decide whether a mismatch is a $45 footnote or a daily annoyance.
What each plug actually is
J1772 is the AC connector: the round five-pin plug on every non-Tesla EV and public Level 2 station of the last decade. When a car “has CCS1,” it has a J1772 inlet with two extra DC pins beneath it — home charging still happens through the J1772 part. NACS (SAE J3400) is Tesla’s compact two-pin design, opened to the industry in late 2022 and standardized by SAE through 2023–2024; one inlet handles both AC home charging and DC fast charging. Nothing about the electricity changes — the same 240 volts at the same amps either way. What changes is the shape of the hole, and whether an adapter has to live between your charger and your car.
The sentence to remember: match the charger’s plug to the port your car uses for AC charging at home. For almost every native-NACS car that is the NACS port itself. The two exceptions below are cars whose NACS port is fast-charge-only — at home, they are J1772 cars wearing a NACS badge.
Which cars ship native NACS — 2025–2026, verified
| Model | Native NACS from | Home-charging note |
|---|---|---|
| Hyundai IONIQ 5 | 2025 | CCS adapter included; the 2025 IONIQ 5 N stayed CCS |
| Kia EV6 | 2025 | Standard NACS port |
| Lucid Gravity | 2025 | The Lucid Air sedan is still CCS |
| Hyundai IONIQ 9 | 2026 | Native port at launch |
| Kia EV9 | 2026 | 2024–25 EV9 is CCS, with an adapter |
| Rivian R1T / R1S | 2026 | Earlier trucks are CCS; the R2 is also native for 2026 |
| Cadillac OPTIQ | 2026 | GM’s only native model for 2026 — the rest of GM follows in 2027 |
| Toyota bZ | 2026 | Both J1772 and CCS adapters bundled with the car |
| Lexus RZ | 2026 | Adapters ship in a case in the cargo area |
| Subaru Solterra | 2026 | 2023–25 Solterra is CCS |
| Genesis GV60 / Electrified GV70 | 2026 | Genesis’s first native-port models |
| Nissan LEAF | 2026 | Dual port: NACS is DC-only — home charging uses its separate J1772 port |
| Mercedes-Benz CLA | 2026 | Dual port: same split — J1772 for AC, NACS for DC |
Verified against manufacturer announcements and releases, November 2026. Still J1772/CCS across their 2026 lineups: Ford (every model), GM except the OPTIQ, Honda and Acura, Volkswagen, Volvo, BMW, the Lucid Air, the Kia Niro EV, and the Hyundai Kona Electric. If a listicle tells you Ford or GM “went NACS in 2025,” it is describing adapter access to Superchargers, not the port on the car.
Adapters: two different parts that share a name
AC adapters and DC adapters are not interchangeable, not electrically and not physically in intent. Ford’s own warning is the bluntest: never use a NACS AC adapter at a DC fast charger. A DC adapter works only at fast chargers and does nothing at a home wall box; an AC adapter does nothing at a Supercharger. The safety standard written for these parts is UL 2252 (first edition March 2025), and it draws the only line we trust: certified, or not.
| Adapter | Job | Certification | Price |
|---|---|---|---|
| Your automaker’s DC adapter | CCS car at Superchargers | OEM-approved | $200–$225 (Ford, GM, Honda) |
| Lectron Vortex Plus | CCS car at Superchargers | UL 2252 certified (SGS) | $184.99 at Lectron |
| A2Z Typhoon Pro | CCS car at Superchargers | Not certified — maker says “underway” | Direct from A2Z |
| Lectron NACS → J1772 (48A) | J1772 car on a NACS home charger | UL 2252 listed | See listing |
| A2Z Stellar Plug | J1772 car on a NACS home charger | UL 2252 / CSA, cert. 80265273 | $130 direct from A2Z |
| A2Z Atom | NACS car on a J1772 home charger | UL 2252 / CSA, cert. 80259177 | $45 direct from A2Z |
| Tesla J1772 adapter | NACS car on a J1772 charger | Tesla OEM — ships in the car | $50 at Tesla Shop |
| TeslaTap | J1772 car on Tesla chargers | No UL/ETL listing published | Not recommended |
The warranty layer sits on top of the certification layer. GM states that damage from an adapter it didn’t sell or provide can void portions of the battery warranty; Ford says to use only adapters sold or provided by Ford or Tesla at Superchargers. For DC fast charging, the hierarchy is simple: your automaker’s adapter first — several brands gave them free in 2024–25, and those programs have largely closed — then the one certified aftermarket option, the Vortex Plus. The original Lectron Vortex (no “Plus”) is not the certified one; the names differ by one word and the certification differs entirely. A2Z’s Typhoon Pro may well join the certified list, but as of this check its own product page says certification is in progress, so it doesn’t get a buy button here. For home AC charging the stakes are lower and the certified options are cheap — which is exactly why there’s no excuse for an uncertified one. TeslaTap has sold for years on reputation, but it publishes no UL or ETL listing, and with certified equivalents at $45–$150 that trade no longer makes sense.
Lectron Vortex Plus — for CCS cars at Superchargers
The first publicly available NACS-to-CCS adapter certified to UL 2252 (by SGS, an OSHA-recognized lab), rated 500 amps and 1,000 volts, with the interlock the original Vortex lacked. It is a road-trip part, not a home part — it will never plug into your wall box — and it doesn’t override your automaker’s warranty language, so owners whose brand offers an OEM adapter should start there. For everyone else with Supercharger access, this is the aftermarket adapter we’d buy.
Lectron NACS → J1772 Adapter (48A) — for a J1772 car on a NACS charger
The home-charging direction most households actually need: your J1772 car, a Tesla Wall Connector or other NACS charger. This one is UL 2252 listed and rated for the full 48 amps a home circuit delivers, so it never becomes the bottleneck. One hard limit, printed on Lectron’s own page: AC only — it does nothing at a Supercharger, and it is not a fast-charging part.
So which charger do you buy today?
- Your car is native NACS and it’s the long-term car: buy the NACS version of the wall charger. Every pick in our flagship comparison that comes in both flavors — Emporia Pro and Classic, ChargePoint Home Flex — is sold as a NACS model; no adapter in your daily path.
- Your car is J1772, or the household is mixed: buy J1772, or buy the bridge. A J1772 charger plus a certified $45–$50 J1772-to-NACS adapter is a setup the automakers themselves anticipate — Toyota and Lexus bundle exactly that adapter with their NACS cars. The deluxe version of the bridge is Tesla’s Universal Wall Connector ($660 at Tesla’s shop, checked November 2026, against $585 for the standard unit): the J1772 adapter is built in and docks in the unit.
- Don’t plan around a third-party adapter on Tesla’s standard Wall Connector: Tesla’s own installation manual prohibits adapters on it. The Universal model exists precisely because that’s the sanctioned route.
- Buying a 2026 Leaf or CLA? Ignore the NACS headlines — your home charging is J1772. Buy the J1772 charger.
- Panel comes before plug: none of this matters if the circuit can’t feed the charger. Run the Readiness Checker first; connector choice is a two-minute decision once the amperage is settled.
