EV charging connectors look similar at a glance but are not interchangeable. The shape of your charging inlet is defined by a connector standard, and every part that touches that port — including a charging port cover — has to match it. Here is a clear map of the five standards you will actually encounter.
The five standards
| Standard | Regions | AC / DC | Notes |
|---|---|---|---|
| Type 2 (IEC 62196-2) | Europe, most of Asia-Pacific | AC | The European AC standard; also known as Mennekes. Used for home and public AC charging up to 43 kW. |
| J1772 (SAE J1772) | North America | AC | The North American AC standard (Type 1). Same shape as the AC half of CCS1. |
| CCS1 | North America | AC + DC | J1772 AC connector with two DC pins below — the combo inlet found on most North American EVs. |
| CCS2 | Europe, global | AC + DC | Type 2 AC connector with two DC pins below — the combo inlet on most European EVs. |
| GBT (GB/T 20234) | China | AC + DC | The Chinese standard, with separate AC and DC connector shapes. |
Why it matters for your port
The inlet on your car is one of these shapes — not a brand-specific design (with one notable exception, Tesla’s North American NACS connector, which we cover below). When you buy accessories for the port, you must buy the version that matches the standard:
- A Type 2 dust cap fits Type 2 AC ports and the AC section of CCS2 combo inlets.
- A J1772 dust cover fits J1772 ports and the AC section of CCS1 inlets.
- CCS1 / CCS2 covers are sized for the full combo inlet including the DC pins.
- GBT covers match the Chinese-standard interface.
This is why a charging port cover is sold by standard, not by car model. Our EV charger cover page lists each standard version separately, so you can match yours in seconds.
The Tesla / NACS case
Tesla’s North American vehicles use the NACS (North American Charging Standard) connector, introduced on new models from 2023 and adopted by many other manufacturers since. European Teslas use Type 2, and older North American Teslas used a proprietary connector with an adapter for J1772. If your car has a NACS inlet, contact us with a photo of the port — we will confirm whether a standard version fits or whether a custom profile is needed.
How to identify your standard without a manual
- Check the charge port shape: a J1772-style round opening with pins below means CCS1; a Type 2-style oval with pins below means CCS2.
- Check your market: Europe = Type 2 / CCS2; North America = J1772 / CCS1 / NACS; China = GBT.
- Check the charging cable you use at home: the plug that goes into the wall tells you the AC standard (Type 2 in Europe, J1772/NACS in North America).
- When in doubt, photograph the port and send it to us — we confirm the right cover version before you order.
Bottom line: one standard, one cover. Match the connector type, not the brand. Once you know whether your car is Type 2, CCS1, CCS2, J1772, GBT or NACS, choosing the right port cover — and the right charging cable, adapter or extension — becomes straightforward.
