- Tesla’s opened its Supercharger network to non-Teslas
- Ford and Rivian were the first non-Teslas to plug in
- Access takes an automaker-provided adapter or Tesla Magic Dock
- In most cases there are software components and it’s more than just an adapter
By the end of 2024, nearly ever major EV brand selling cars in the U.S. had signed on to offer Tesla Supercharger access, and eventually adopt the automaker’s NACS port for future EVs. But the rollout has proceeded at different speeds for each brand.
Owners of EVs from most non-Tesla brands must use an adapter to connect with Supercharger stations until the widespread rollout of new cars with NACS ports, a process that recently started with the 2025 Hyundai Ioniq 5 and is aided by the formalization of NACS as a true standard by the SAE in late 2023.

Most automakers are also pushing software updates that allow their EVs to properly interface with Supercharger stations for plug-and-charge operation, as well as updates that allow Supercharger stations to appear on in-vehicle route planning and payment apps. With these updates in place, Tesla’s Magic Dock adapter at many Supercharger stations may work in lieu of a separate automaker-provided adapter.
As with the original announcements of the switch to the Tesla charge port, Ford led the way in providing adapters to let customers fast-charge at Supercharger stations. That started in February 2024, with other automakers following later in the year and a few now confirmed for the first half of 2025. Here’s where things stand now.
Automakers that have Supercharger access:
Ford
Rivian
General Motors
Volvo
Polestar
Nissan
Automakers said to be getting Supercharger access “soon” according to Tesla:
BMW
Genesis
Hyundai
JLR
Kia
Lucid
Mercedes-Benz
As Green Car Reports has pointed out before, Tesla’s V4 hardware will likely be able to handle electric vehicles that charge at 800 volts at the full rate. But Tesla’s V3 hardware—the majority of North American hardware available on the Supercharger network at this time—the limit is 400 volts, or maybe a little bit higher.
That creates a dilemma for automakers already selling vehicles with 800-volt charging, as those cars will charge slower at Tesla V3 Supercharger stations than they would at the most powerful CCS stations. But the more widespread deployment of V4 Superchargers will help solve that, along with the buildout of the Ionna fast-charging network backed by eight automakers that’s expected to include both CCS and NACS connectors.
