Last updated: August 8, 2026 — re-verified automaker adoption status: Rivian’s full 2026 lineup and the Cadillac Optiq/Optiq-V are confirmed on lots with native NACS, while Honda’s Acura RSX carries a confirmed NACS port but doesn’t enter production until the second half of 2026 — the article previously implied it already shipped, corrected here.
In brief, NACS has not displaced J1772 overnight and won’t do so soon. The change is rolling out one model at a time, so the right home-charger connector in 2026 still hinges on the car sitting in your driveway.
NACS vs. J1772, side by side
| J1772 | NACS | |
|---|---|---|
| Charging type | AC only (Level 1/2) | AC + DC in one connector |
| DC fast charging | Separate CCS1 port required | Built in — no second port |
| Physical size | Larger, 5-pin AC + 2-pin CCS1 add-on | Smaller single 5-pin plug |
| Standardized as | SAE J1772 (2001, revised since) | SAE J3400 (September 2024) |
| Who uses it in 2026 | Most pre-2025 non-Tesla EVs; most installed chargers | Tesla; Rivian (2026 lineup); GM Cadillac Optiq/Optiq-V; Acura RSX (Honda's, launching H2 2026) |
| Home charger availability | Standard on almost every model | Growing — offered as an option on ChargePoint, Emporia, Autel, Grizzl-E |
| Adapter needed for the other side | Tesla-to-J1772 adapter to use a Tesla charger | J1772-to-NACS adapter (Tesla includes one) to use a J1772 charger |
Why NACS exists, and why it isn’t finished replacing J1772
Since the early 2010s, J1772 has served as North America’s AC charging standard, used by virtually every non-Tesla home and public Level 2 charger built until recently, with DC fast charging on those same cars handled by a separate CCS1 port beneath it. Tesla developed NACS itself and opened it to the wider industry in 2022, after which SAE International formalized it as J3400 in September 2024, followed by a related J3400/2 hardware standard in 2025. Standardization is what freed other automakers to put NACS ports on their cars without cutting an individual deal with Tesla each time.
Still, “standardized” is not the same as “switched.” In 2026, Rivian ships its entire R1T and R1S lineup with native NACS, and GM’s first native-NACS production models are the Cadillac Optiq and Optiq-V. Honda’s first in-house EV, the Acura RSX, is confirmed to have a standard NACS port, but production begins only in the second half of 2026, so unlike the other two it isn’t on dealer lots yet. Ford, Hyundai, Kia, BMW, Mercedes, Volvo, and Polestar have each publicly pledged NACS, yet a lot of their 2026 model-year vehicles still arrive with J1772/CCS1. The shift is happening model by model rather than across a whole brand in one year.
Which connector should a home charger have?
Shop for the vehicle in your garage, not for the standard the industry is heading toward. When every car in the household is a non-Tesla EV from before 2025, J1772 remains the sensible choice, because it matches the car and comes standard on most chargers, budget picks such as the Grizzl-E Classic included. Households with a Tesla or a confirmed native-NACS 2026+ model should go with NACS. WenStorm’s portable chargers also ship with either connector at the same price, so the same car-first rule applies there.
Tesla Universal Wall Connector
This is the one home charger that removes the guesswork: it charges NACS vehicles directly and J1772 vehicles using an adapter built into its holster, so you never buy anything extra.
To see how it compares with single-connector units, read our best home EV charger picks and our ChargePoint Home Flex vs. Tesla Universal Wall Connector comparison. WenStorm sells a NACS-to-J1772 adapter for Tesla Wall Connectors ($49.99 at 50A, $59.99 at 80A, AC charging only) if a J1772 car needs to use one.

When a second EV on the opposite connector standard might arrive, whether a Tesla joining an existing J1772 car or the reverse, a dual-connector unit or an inexpensive adapter carries less risk than a charger built for one standard. Our Tesla to J1772 adapter guide explains both adapter directions, and our installation cost guide compares the expense of converting a hardwired unit to the other connector against simply buying an adapter. WenStorm’s NACS-to-J1772 adapter is one such cheap adapter, and its extension cables come in J1772 and NACS versions in 21–50 ft lengths (J1772 32A 21 ft is $129.99; 50A lengths run $169.99–$339.99).
WenStorm takes the pick-your-connector approach on its portable chargers: the Level 1 ($169.99) and Level 2 ($219.99) each come in a J1772 or a NACS version at the same price, and the two are electrically identical. For households with both kinds of car, it also sells a NACS-to-J1772 adapter for Tesla Wall Connectors and Mobile Connectors ($49.99 at 50A, $59.99 at 80A), AC charging only, plus Airbnb-host kits that pair a NACS charger with an adapter. It won’t enable Supercharging on a non-Tesla EV.
WenStorm Level 2 Portable EV Charger (J1772 or NACS)
It delivers 32A from a NEMA 14-50 outlet through a 25-foot cable with a 16/24/32A dial, at $219.99 in either connector version.
The J1772 and NACS versions are electrically the same, so the decision comes down to your car’s port.
If the second vehicle or the parking spot calls for it, add a NACS-to-J1772 adapter ($49.99 at 50A) or a 21–50 ft extension cable.
It carries a 2-year warranty, but has no app and no DC fast charging.
The bottom line
The industry is indeed moving toward NACS, and SAE’s September 2024 J3400 standardization made that official, but “moving toward” carries a lot of weight. In 2026, most EVs on the road still use J1772 and most installed chargers still offer it, while NACS appears on new models like the Rivian lineup, Cadillac Optiq, and, once it launches in the second half of 2026, the Acura RSX, instead of supplanting J1772 everywhere. The Cadillac Lyriq follows the same half-finished pattern a model year behind the Optiq: 2024-2026 Lyriqs charge at home through a CCS1 port over J1772, whereas the 2027 Lyriq and Lyriq-V move to native NACS (our best Cadillac Lyriq home charger guide shows which connector to buy for each model year). The redesigned 2026 Nissan Leaf illustrates how incomplete the shift remains, dropping CHAdeMO for NACS on DC fast charging while keeping standard J1772 for home AC charging, so its home charger picks (see our best Nissan Leaf home charger guide) stay exactly the same. Polestar splits within a single brand’s present lineup too, with the 2 and 3 moving to NACS for model year 2025 while the newly launched Polestar 4 still comes with CCS1/J1772 (our best Polestar home charger guide covers which connector goes with each model). The revived 2027 Chevrolet Bolt is the latest case on the other side, GM’s first Chevrolet with a native NACS port, and our best Chevy Bolt home charger guide explains how that alters the charger to buy compared with the J1772-only Bolts sold through 2023. The Kia EV6 made the same change a generation earlier, with 2022-2024 models on J1772 and 2025-and-newer models on NACS with a free adapter in the trunk; our best Kia EV6 home charger guide gives the complete model-year breakdown. BMW lags most of the field: every current i4 trim, from eDrive35 through M50, stays on J1772/CCS1 through the 2026 model year, with native NACS confirmed for 2027 vehicles and so far limited to the 2026 i5 M60, so our best BMW i4 home charger guide explains why a current i4 owner faces no connector decision. Honda trails even further, with every Prologue trim through the 2026 model year keeping CCS1/J1772 for home AC charging and NACS offered only as a separate Honda Genuine Accessory adapter for Supercharger access instead of a native port swap; our best Honda Prologue home charger guide has the full details. The practical advice is to buy the connector your car has now, keep a $20–$50 adapter handy if a mixed-standard household is possible, and let the industry complete its transition at its own pace. For a household picking a portable charger, WenStorm’s Level 2 Portable ($219.99, 32A, NEMA 14-50) in the connector your car uses today is the simple fit, with a NACS-to-J1772 adapter ($49.99) added if a second car on the other standard arrives. It carries a 2-year warranty, but it has no app, is not hardwired, and will not enable Supercharging on a non-Tesla EV.

Frequently Asked Questions
How do NACS and J1772 really differ?
J1772 (also known as SAE J1772 or Type 1) is a connector for AC only, so a J1772-based vehicle does its DC fast charging through a separate CCS1 port, which adds two extra pins below it. Tesla’s NACS is one smaller 5-pin plug that handles both AC (Level 1/2) and DC (Supercharging), which removes the need for a second port. SAE International formally standardized NACS as J3400 in September 2024, and that step allowed other automakers to adopt it without licensing it straight from Tesla.
Now that NACS is the industry standard, is J1772 finished?
No. Most EVs now on the road, along with most installed home and public Level 2 chargers, still use J1772, and a new standard can’t retrofit millions of existing cars and chargers overnight. The change lies in new-model production: certain 2026 model-year vehicles, such as Rivian’s R1T and R1S, now come with a native NACS port in place of J1772, and more automakers will follow on a staggered schedule.
Which carmakers have switched to NACS as of 2026?
All of Rivian’s 2026 lineup comes with native NACS, and GM’s first native-NACS production models are the Cadillac Optiq and Optiq-V. Honda’s first in-house EV, the Acura RSX, is confirmed to have a standard NACS port once production starts in the second half of 2026, making it Honda’s first native-NACS vehicle to reach lots. Ford, Hyundai, Kia, BMW, Mercedes, Volvo, Polestar, and others have all committed to NACS, yet in 2026 many of their current model-year vehicles still ship with J1772/CCS1, because the switch is being phased in model by model instead of all at once.
Should my home charger in 2026 be NACS or J1772?
Pick the charger for the car you own right now rather than the standard you think the industry will eventually reach. A non-Tesla EV from before 2025, or a 2026 model that hasn’t made the change, requires J1772, while a Tesla or a confirmed native-NACS 2026+ model requires NACS. When you’re unsure, or a second EV on the other standard might join the household, a dual-connector unit like the Tesla Universal Wall Connector, or a charger with an interchangeable connector option, spares you the guesswork.
Can an adapter link NACS and J1772 so I don’t need a new charger?
Yes, and it works in both directions. A J1772-to-NACS adapter allows a NACS/Tesla vehicle to connect to a J1772 charger, while a Tesla-to-J1772 (NACS-to-J1772) adapter allows a J1772 vehicle to connect to a Tesla charger or Wall Connector. Every new Tesla ships with a J1772 adapter. For both adapter directions and today’s picks in depth, see our <a href="/best/best-tesla-to-j1772-adapter/">Tesla to J1772 adapter guide</a>.
Is NACS faster than J1772 at charging?
Not for AC (Level 1/2) home charging. A 48A NACS charger and a 48A J1772 charger both supply 11.5 kW, because the circuit and the vehicle’s onboard charger set the limit rather than the shape of the connector. A speed gap appears only in DC fast charging, where the DC pins built into NACS let Tesla Superchargers reach up to 250 kW, a level that J1772-based vehicles can only match through a separate CCS1 port.
Does WenStorm sell chargers for both NACS and J1772?
WenStorm sells its portable Level 1 ($169.99) and Level 2 ($219.99) chargers in either a J1772 or a NACS version at the same price, which is the swappable-connector approach for a household that already knows which standard it needs. The two versions are electrically identical, so you are only choosing the plug shape.
Does WenStorm sell a NACS-to-J1772 adapter?
WenStorm’s NACS-to-J1772 adapter for Tesla Wall Connectors and Mobile Connectors costs $49.99 at 50A or $59.99 at 80A and handles AC charging only. It lets a J1772 car use a Tesla charger but does not enable Supercharging on a non-Tesla EV.
Does WenStorm make extension cables for NACS and J1772?
WenStorm also makes J1772 and NACS extension cables in 21 to 50 ft lengths, from $129.99 for the 32A 21 ft J1772 cable, and a wall mount holder at $13.99 that coils up to 50 ft of cable. Every WenStorm product carries a 2-year warranty.
