If you're new to electric driving, the number of plug types can be confusing at first. Every charging station lists a connector type, and if you don't recognize it, it's hard to know whether you can actually use that station. Here's a practical, no-nonsense guide to every connector you'll actually encounter on the road in 2026, plus what adapters can and can't fix, so you can plan with confidence.

The connectors you'll actually see

Type 2 is the standard AC connector across Europe, used for slow and normal charging (up to 22 kW) at home, at work, and at public normal-speed stations. Almost every new EV sold in Europe supports it, which makes it the connector you'll see most often in parking garages, supermarkets, and residential streets. It's a round plug with a flat top, and it typically takes anywhere from 4 to 10 hours to fully charge a car, depending on battery size and available power.

CCS (Combined Charging System) combines a Type 2 plug with two extra pins below it for DC fast charging, delivering up to 350 kW at the fastest stations. This is the dominant fast-charging standard in Europe and is increasingly adopted in North America as well. If you're planning a long road trip, CCS stations are what you'll rely on for a 15-30 minute top-up instead of an hours-long wait.

CHAdeMO is an older DC fast-charging standard, mainly used by older Nissan Leaf and Mitsubishi Outlander PHEV models. Fewer new charging stations are being built with CHAdeMO support these days, since the industry has largely moved toward CCS, so if your car relies on CHAdeMO, it's worth checking availability along your route before you set off.

Tesla connectors vary by region: newer Teslas sold in Europe ship with a standard CCS port, meaning they can charge at any CCS station just like other EVs. North American Teslas, on the other hand, have historically used Tesla's own proprietary NACS plug, though this is changing rapidly as other manufacturers adopt NACS too. If you drive a Tesla, always double-check which connector your specific model and region uses.

NACS (North American Charging Standard) is Tesla's own connector, now adopted by most major automakers in North America and standardized as SAE J3400. In the US and Canada, NACS increasingly appears alongside or instead of CCS1 at charging stations, and by 2026 most new non-Tesla EVs sold in North America ship with a native NACS port rather than needing an adapter.

GB/T is China's national charging standard, used by the vast majority of EVs sold there, which makes up the largest share of EVs on the road worldwide. GB/T uses separate connectors for AC and DC charging and is not physically compatible with CCS or Type 2. A next-generation connector called ChaoJi, developed jointly by China and Japan's CHAdeMO consortium, aims to eventually replace both GB/T and CHAdeMO with a single ultra-fast standard, though the rollout remains gradual as of 2026.

In markets like India, you'll often see the connector referred to as CCS2 rather than just "CCS" - it's the same DC fast-charging standard used in Europe, paired with Type 2 for AC charging.

Connectors at a glance

Adapters: what they can and can't fix

Adapters bridge a physical connector mismatch, but they don't add capability your car doesn't have. A Tesla-to-CCS adapter (or the reverse, for non-Tesla cars using Tesla Superchargers) lets the plug fit, but your charging speed is still capped by whichever side has the lower limit - car, cable, or station. CHAdeMO-to-CCS adapters exist but are rare and expensive, and most drivers relying on CHAdeMO are better off simply route-planning around CHAdeMO-capable stations rather than hunting for an adapter. GB/T-to-CCS adapters are uncommon outside China and generally not something to plan a trip around.

Why the connector alone doesn't tell you the charging speed

Matching connector shapes only tells you the plug will physically fit - it says nothing about how fast you'll actually charge. AC charging speed is capped by your car's onboard charger (commonly 7.4, 11 or 22 kW, sometimes lower on older or budget models), not by the wall connector's theoretical maximum. DC fast-charging speed is capped by your battery's chemistry, temperature, and state of charge - a "350 kW-capable" station will still only deliver what your specific car's battery can accept at that moment, which is often far lower, especially above 80% charge or in cold weather. Always check your vehicle's actual charging curve rather than assuming you'll get the station's advertised peak number.

Frequently asked questions

Can I use a CCS adapter on any Tesla?

Only on models built with the hardware to support it (typically CCS-native in Europe already, or NACS-to-CCS adapters for North American Teslas visiting a CCS station). Check your specific model and region before assuming compatibility.

Is CHAdeMO disappearing?

Effectively yes for new infrastructure - very few new public chargers are being built with CHAdeMO connectors in 2026, though existing ones remain in service. If your car depends on it, verify availability on your route rather than assuming coverage.

Will NACS fully replace CCS in North America?

It's heading that way - most major automakers have committed to NACS, and many new non-Tesla EVs already ship with a native NACS port. CCS1 infrastructure will remain usable for years via adapters, but new stations increasingly prioritize NACS.

Why did my car charge slower than the station's maximum kW?

Because the station's number is a ceiling, not a guarantee - your actual speed depends on your battery's charging curve, current state of charge, and temperature, all of which typically matter more than the station's headline figure.

Getting the wrong connector type wrong isn't just inconvenient, it can mean driving out of your way for nothing. In Elunio, you can filter search results by exactly the connector type your car needs, so every station you see in your results is one you can actually plug into. Combined with real driving distance instead of straight-line estimates, this makes trip planning far less stressful.

A quick history: how we ended up with so many connector standards

Today's tangle of connector types didn't arrive all at once - it's the result of several regions independently solving the same problem before anyone agreed on a common standard. CHAdeMO was the first mass-market DC fast-charging standard, developed in Japan and launched in 2010 alongside the original Nissan Leaf; for several years it was the only fast-charging option many EV drivers had. In Europe, Type 2 (also called Mennekes, after the company that designed it) became the mandated AC standard for the EU, ensuring every charging point installed across the bloc used the same plug for home and public AC charging. As DC fast charging matured, Europe and North America each extended their existing AC connector with two extra DC pins to create the Combined Charging System: CCS1 pairs those DC pins with the North American J1772 AC connector, while CCS2 pairs them with Type 2, which is why CCS looks different depending on which side of the Atlantic you're on. Tesla, meanwhile, built its own proprietary connector from scratch, which by 2025 had been opened up and standardized industry-wide as NACS (North American Charging Standard), officially SAE J3400. China went its own way entirely with the state-mandated GB/T standard, used only domestically. Through 2025 and into 2026, the North American market has been consolidating rapidly around NACS, with most manufacturers switching over or adding adapters.

How to check exactly which connector your car needs

The most reliable way to find out is simple: look at your charging port and check your owner's manual, since both will state the connector type directly. That said, a few regional rules of thumb help you know what to expect before you even check. If your car is registered in the EU, Switzerland, Norway, Iceland, or the UK, it uses Type 2 for AC charging and CCS2 for DC fast charging, regardless of brand - this applies uniformly across the region. In the US and Canada, cars sold before 2025 typically use J1772 for AC and either CCS1 or Tesla's proprietary connector for DC, while 2025 and newer models increasingly ship with a native NACS port as manufacturers like Ford, GM, Rivian, and Volvo shift over. Nissan Leaf models sold in Japan, and older Leafs sold internationally, use CHAdeMO for DC fast charging paired with a Type 1 or Type 2 AC inlet. You can also identify a connector visually: a round plug with pins arranged in a circle plus two larger flat blades underneath is Type 2/CCS2; a similar round plug without the two big DC blades is Type 1; and a chunky rectangular plug with a physical locking latch is CHAdeMO. If all of this still feels like guesswork, Elunio's app takes the decision out of your hands entirely - it filters charging station search results by your selected car's exact connector type automatically, so you only ever see stations you can actually plug into.

What changes when you charge in a different country

Within Europe, the connector itself is rarely the problem: all 27 EU member states, plus Norway, Switzerland, and the UK, use the same Type 2 and CCS2 standards, so you don't need an adapter just because you've crossed a border. What actually changes from country to country is everything around the plug - which payment methods are accepted, which charging networks and apps have good coverage, and how pricing is structured. Many countries legally require public DC fast chargers to accept ad-hoc contactless card payment as a fallback, precisely so that a driver without a local account or app isn't left stranded, though coverage and enforcement of this rule still varies. Outside Europe, the picture is different: North America is currently mid-transition between CCS1 and NACS, so depending on your car and the station you're visiting, you may need a physical adapter to plug in - most manufacturers now sell an official adapter for exactly this situation. Before any cross-border trip, it's worth checking your charging app's coverage map for the destination country in advance, rather than assuming the network you rely on at home will be just as strong once you cross the border.
