Why

  • ✓ NACS / SAE J3400 charge connector (Tesla-style) works on CCS1 (Combined Charging System, Combo 1) charge port only with the Vehicle-maker-approved NACS-to-CCS1 DC adapter (e.g., GM NACS DC Adapter, Ford Fast Charging Adapter); DC fast charging only.

Conditions

  • Vehicle-maker-approved NACS-to-CCS1 DC adapter (e.g., GM NACS DC Adapter, Ford Fast Charging Adapter); DC fast charging only: NACS / SAE J3400 charge connector (Tesla-style) doesn't mount directly on CCS1 (Combined Charging System, Combo 1) charge port.

Good to know

  • Needs the Vehicle-maker-approved NACS-to-CCS1 DC adapter (e.g., GM NACS DC Adapter, Ford Fast Charging Adapter); DC fast charging only. Without it, this won't attach.
  • Any J1772 Level 1/Level 2 charger plugs straight into a CCS1 port (the top half of the CCS1 inlet is a J1772 inlet).
  • Tesla Superchargers (NACS) need an adapter provided or approved by YOUR vehicle maker; Tesla says third-party adapters are prohibited at Superchargers for safety reasons.
  • GM's NACS DC Adapter (GM part numbers 85090442, 85836744, 85778137) works only at approved DC fast chargers; GM says it must not be used on Level 1/Level 2 AC home chargers and doing so can set trouble codes (P2E85, P0F71, P0D3F).
  • Ford's Fast Charging Adapter (NACS) is required for F-150 Lightning and Mustang Mach-E at upgraded Tesla Superchargers.
  • Adapters are vehicle-maker specific: a GM adapter is not approved for a Ford, and vice versa.
  • Native NACS-port vehicles (all Teslas, 2025 IONIQ 5, and new NACS-equipped models) do not need an adapter at Tesla Superchargers.
  • To use a J1772 Level 2 station, a NACS-port car needs a J1772 adapter. Tesla's SAE J1772 Charging Adapter supports up to 19.2 kW and is included with every new Tesla.
  • To use a CCS1 DC fast charger, a NACS-port car needs a CCS1 DC adapter: Tesla's CCS Combo 1 Adapter (up to 250 kW; not compatible with Cybertruck; some vehicles need a retrofit) or the vehicle maker's own adapter (Hyundai sells 2025 IONIQ 5 models with a CCS adapter).
  • Tesla warns that using an AC adapter at a Supercharger may damage your vehicle.
  • Safety: this checks the connector and adapter only. Use adapters and chargers your vehicle maker approves, and have a licensed electrician install hardwired chargers and circuits.
