How fast each charging level really is, which connector your next car will use, what a home Level 2 install involves, and the home chargers compared on the makers' own published specs.
Charging is the part of EV ownership that sounds complicated and mostly isn't: nearly all charging happens at home, overnight, on Level 2.
This page explains the three levels with the regulators' own figures, untangles the connector change now under way in North America, walks through what a home install actually involves, and compares the home Level 2 chargers on published specs.
Figures are quoted per source — US EPA, Natural Resources Canada (NRCan) and the US DOE — and are never averaged together; the sources measure differently, so their numbers differ. Charger specs are the makers' published figures, researched October 2026. Where a maker does not publish a figure, the table says so rather than guessing.
How fast each level really is, in the regulators' own figures — quoted per source, never averaged.
The US EPA puts Level 1 at about 3–5 miles of range per hour of charging. Natural Resources Canada lists 3–8 km of range per hour, and a full charge can take 8–50+ hours. Level 1 suits low daily mileage and plug-in hybrids; per the US DOE AFDC, it may need no extra spend if a dedicated outlet already exists near where you park.
The US EPA puts Level 2 at roughly 25–40 miles of range per hour. Natural Resources Canada lists 16–50 km per hour, with a full charge typically taking 4–10 hours.
The US EPA puts DC fast charging at roughly 100–200+ miles of range in 30 minutes. Natural Resources Canada lists about 20–30 minutes for a partial charge. This is public infrastructure, not something installed at home.
Four connectors, and one change under way: North America is moving to NACS, now standardized as SAE J3400.
The standard North American AC connector for Level 1 and Level 2 — Natural Resources Canada notes all major manufacturers support it. The US EPA lists J1772 and J3400/NACS as the two home-charging connector families, noting some newer vehicles from model year 2025 began using J3400/NACS.
J1772 plus two extra DC pins for fast charging; Natural Resources Canada describes the SAE Combo as used by most automakers except Tesla. It is being displaced on new models by NACS ports, but the installed base of CCS cars is large and CCS1 remains widely deployed on non-Tesla fast chargers.
Tesla opened the connector design to other makers in 2022 (Natural Resources Canada calls it a preferred connector type for vehicles in Canada). SAE International published the J3400 Technical Information Report on December 19, 2023, and the J3400 Recommended Practice in October 2024; a dimensional standard, J3400/2, followed in April/May 2025. With standardization the acronym's expansion changed from "North American Charging Standard" to "North American Charging System."
Natural Resources Canada notes CHAdeMO is not widely used except by Nissan and Mitsubishi. No new battery-electric car sold in North America ships with it: the all-new 2026 Nissan LEAF drops CHAdeMO for a dual-port layout — J1772 for AC and a NACS port for DC fast charging up to 150 kW. But one new model still offers it: the 2026 Mitsubishi Outlander PHEV charges at 50 kW on a CHAdeMO DC fast charger (about 29 minutes, per Mitsubishi Motors Canada) — reportedly the last new vehicle sold in the US with a CHAdeMO port. Existing LEAFs stay on the CHAdeMO network; Nissan offers no NACS adapter for them (as reported).
Adapter safety. For DC fast charging, use only your vehicle manufacturer's approved adapter. Honda's official guidance states its adapter is the only DC fast-charging adapter Honda approves, that Tesla requires approved adapters at Superchargers, and that damage caused by unapproved adapters may not be covered by the vehicle's limited warranty. Adapter safety now has its own standard — UL 2252, published March 2025 — and the J3400 family includes J3400/1 for adapter safety. The same rule of thumb applies to AC adapters: choose listed/certified products from known makers.
Native NACS ports and Supercharger access, maker by maker — confirmed from the makers' own releases.
Access to Tesla Superchargers rolls out brand by brand, is limited to compatible (V3/V4) stalls, and requires either a native NACS port or the vehicle maker's adapter (per Tesla Support).
| Automaker | Native NACS ports from | Supercharger access |
|---|---|---|

| Hyundai | Q4 2024 / 2025 models — the 2025 IONIQ 5 was Hyundai's first with a native NACS port | Via a Hyundai adapter; 20,000 US Superchargers (March 2025) |
| Kia | 2025 EV6 and 2026 EV9 come standard with NACS ports | Live as of April 2025 via adapters — 21,500+ Superchargers |
| Nissan | From 2025 — first shipped on the 2026 LEAF | Ariya from December 10, 2024, via a Nissan adapter — 17,800 Superchargers |
| Honda / Acura | Announced from 2025 (adapter access is verified from Honda's own release; native-port timing rests on Honda's earlier announcement) | Prologue and ZDX from June 2025 — 20,000+ selected Superchargers, via the Honda-approved adapter |
| Mercedes-Benz | Late 2025 in the North American lineup | US from February 2025 via a Mercedes-approved adapter; Canada followed in 2025 |
| Volkswagen Group (VW, Audi, Porsche, Scout) | From 2025 | 2025 |
Other makers — including BMW, Genesis, Jaguar Land Rover, Lucid, Mazda, Stellantis, Subaru and Toyota — have been reported as moving to NACS, but their adoption was not confirmed from the makers' own releases in the sources checked for this page, so they are not listed as adopted here.

Takeaways. The field's warranty is 3 years — Tesla gives 4 and Enphase 5. At 50 A / 12 kW, the ChargePoint Home Flex and the two Autel units top the 48 A / 11.5 kW field. Several chargers now sell in J1772 or NACS versions of the same unit — buy the connector your next car will use, not just the one your current car has.
