I’m Sitting at a Tesla Supercharger Station, and It Says It Is Not Compatible, but I'm Using the Adapter I Need Help - Let’s Examine the Many Ways Charging a Non-Tesla Vehicle at a Supercharger Can Go Wrong and How To Overcome Challenges

It’s been a few years now since Tesla abandoned its single biggest brand advantage and vowed to open up the Supercharger network to non-Tesla vehicles. The single dumbest move in automotive branding was intended to help EV adoption and allow Tesla to tap into even more federal largess. Now that the program has spread to many large brands that make EVs, owners are finding out that it is not a simple thing to do. Particularly the first time. After all, EV charging in public is a hot mess anyway. Now that the incompatibility between CCS and NACS changing has been added to the mix, things can quickly go wrong. We’ll tell what went wrong in our conclusion, but we will list the most likely causes in order from top to bottom.

Charging a Non-Tesla at a Tesla Supercharger Tip One - Get the Tesla App
You are going to need to pay for your charge. Before heading to the local Supercharger, get the Tesla app and establish a payment method. Add this to the ridiculous list of a dozen or so other apps you need to carry in your phone in order to charge in public. 

Charging a Non-Tesla at a Tesla Supercharger Tip Two - Have the Proper Adapter
Tesla Superchargers use the NACS charging standard, which stands for North America Charging Standard. There are two other DC charging standards in use today in America. The first is CHAdeMO. This standard is used by Nissan and Mitsubishi plug-in vehicles up to the present day. It’s not so much outdated as just the unpopular choice for an automaker to opt into. 

The second is CCS, which stands for Combined Charging System. This system combined AC and DC charging into one handle (sort of). It’s what Chevy Bolts, Mustang Mach-Es, most Hyundais, and pretty much every other brand used besides Tesla, Nissan, and Mitsubishi in the modern era. The original RAV4 EV from the 1990s used a different, even older standard that we will not cover here. There are no public chargers for that vehicle anyway. This is the “Tesla adapter for superchargers” we hear a lot about. You need an NACS to CCS adapter in order to charge your non-Tesla at a Supercharger. 

Don’t confuse a J-plug to NACS adapter with a CCS to NACS
Be sure you don't accidentally grab the wrong adapter. AC charging using a J-plug to Tesla adapter won't work at a Supercharger. Forgive us if this is starting to get confusing, but well, it is confusing. 

Charging a Non-Tesla at a Tesla Supercharger Tip Three - Only Certain Superchargers Are Compatible
Here’s a fun fact: Not all Superchargers can charge non-Tesla cars, no matter what adapter you have with you. That’s because only certain versions of Tesla Superchargers enable such non-Tesla charging. Our pal Tom from State of Charge posted a great video today for Acura Honda vehicle owners, helping them sort out the confusing mess. Here’s part of what Tom covered in that very comprehensive guide. We feel he says it as well as it can be said:

Only V3 and later Tesla Superchargers (will charge non-Teslas). Tesla has gone through different versions of their Superchargers. The V2 that are out in the public now, and there are quite a few of them, will not charge non-Tesla vehicles.

How do you know what version the Supercharger is? One way is to use your (horrible) built-in vehicle navigation system to search for Superchargers. If your automaker did their job right, only compatible Superchargers should show up as options. While you are at it, use the navigation to help you prepare for charging by preconditioning your vehicle battery. You can also do this manually in your vehicle’s EV settings menu. This will speed up your charging session a bit.

So, which of the myriad reasons for a failed charging session at a Supercharger did the person we paraphrased run into as a roadblock? She was at a Tesla Supercharger, but it was not one of the compatible ones. In other words, not a V3 or later version. Likely a V2. We know this from the dozens of helpful comments under her post. As one other owner posted, “People think that the opening of Superchargers was the Holy Grail, but most of them are not compatible. It's not the oasis that folks think it is.”

While Tesla's Supercharger network is a game-changer for EV adoption, long-term Tesla owners have their own perspectives on the brand’s charging capabilities. One Model 3 owner, after 55,000 miles of driving, absolutely loves his car, but recently noticed a concerning drop in range. His experience highlights how battery performance and real-world charging expectations evolve over time. If you’re curious about how Tesla’s charging efficiency holds up in the long run, check out his full story here.

We hope this story helps prepare non-Tesla owners for the many challenges they will face trying to use the Tesla Supercharger network. One final word: We’d stick close to the car while charging since radical crazy people are now targeting the Supercharger network. The Supercharger closest to my own home was set ablaze just a few weeks ago. Be safe.
