The rules behind the answers. These are the details that cause most wrong purchases.
CCS1 (Combined Charging System, Combo 1) charge port
J1772 inlet plus two DC pins; takes J1772 AC plugs and CCS1 DC fast-charging plugs. Used by most non-Tesla EVs built before the NACS switch.
- 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.

CHAdeMO DC fast-charging connector
A DC fast-charging connector used mainly by Japanese automakers (e.g., Nissan LEAF); AC charging on these vehicles uses a separate J1772 port.
- CHAdeMO is DC only and is not interchangeable with CCS1 or NACS DC plugs.
- Fewer new public DC stations offer CHAdeMO than CCS1 or NACS; check station connectors before a trip.

SAE J1772 (Type 1) AC charging connector
The standard plug on non-Tesla Level 1 and Level 2 (AC) charging equipment in North America; it fits J1772 and CCS1 charge ports.
- J1772 is AC only (Level 1 and Level 2). DC fast charging needs CCS1, CHAdeMO or NACS (J3400).
- NACS-port vehicles (all Teslas, 2025 IONIQ 5 and other new NACS models) need a J1772-to-NACS adapter; Tesla includes its SAE J1772 Charging Adapter with every Tesla vehicle delivery.
- GM sells a 'GM NACS Level 2 Adapter' for its J1772/CCS1 vehicles to use NACS AC chargers; GM says to set the Level 2 charger to 'compatibility mode'.

NACS / SAE J3400 charge connector (Tesla-style)
Tesla-designed North American Charging Standard, being standardized by SAE as J3400; one port handles Level 1, Level 2 and DC fast charging.
- 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.
