Key takeaways
- DC fast charging at Superchargers needs a NACS-to-CCS1 DC adapter.
- AC charging needs a different (J1772-to-NACS or NACS-to-J1772) adapter.
- Use automaker-approved or certified adapters only.
Why adapters exist
SAE standardized Tesla's connector as J3400 (NACS), and many automakers have announced NACS ports. During the transition, drivers with CCS1/J1772 ports use adapters to access Tesla's network.

Choosing the right adapter
For DC fast charging at Superchargers, you need a NACS-to-CCS1 adapter supported by your automaker. For home or destination AC charging, a NACS-to-J1772 adapter lets a J1772 car use a Tesla Wall Connector. These are not interchangeable.
Safety and access
Use adapters your automaker approves or that carry a recognized safety certification. Check the automaker's app or Tesla's app to confirm your car is enabled for Supercharger access.
