If you drive a Chevrolet, GMC, Buick, or Cadillac EV and you’ve been eyeing Tesla’s massive Supercharger network, the GM Tesla adapter, officially called the GM‑approved NACS DC adapter, changes the game. It lets many GM EVs plug into select Tesla Superchargers across North America, adding tens of thousands of fast‑charging options to your road‑trip playbook.
Quick snapshot
As of late 2024, most GM EV drivers in the U.S. can buy a GM‑approved NACS DC fast‑charging adapter through their brand’s mobile app for around $225. With it, you can access more than 17,800 Tesla Supercharger stalls, plus other NACS DC fast chargers, directly from your GM charging apps.
Why the GM Tesla adapter matters in 2025
The GM–Tesla charging picture at a glance
For years, Tesla Superchargers were effectively off‑limits to GM drivers. Now, with the GM Tesla adapter, that barrier is largely gone. You can route to compatible Tesla sites directly from the myChevrolet, myGMC, myBuick, or myCadillac app, plug in using the adapter, and pay without juggling multiple accounts.
Why this matters if you’re shopping used
If you’re considering a used Chevy Bolt, Blazer EV, Cadillac Lyriq, or GMC Hummer EV, Supercharger access via the GM NACS adapter instantly makes the vehicle more road‑trip friendly. When you shop with Recharged, every EV comes with a transparent Recharged Score, including verified battery health, so you know that extra fast‑charging capability won’t be wasted on a tired pack.
What is the GM Tesla adapter (NACS DC adapter)?
The GM Tesla adapter is a compact DC fast‑charging adapter that connects a CCS‑equipped GM EV to a NACS (Tesla‑style) cable at compatible DC fast‑charging stations. GM calls it the “GM‑approved NACS DC adapter,” and it’s designed specifically for high‑power DC use at Tesla Superchargers and other NACS DC fast chargers.
- Adapter side: NACS (Tesla‑style) inlet that accepts the Tesla Supercharger cable.
- Vehicle side: CCS1 plug that snaps into your GM EV’s existing DC fast‑charge port.
- Electronics: Built‑in safety features to manage communication between your EV and the Supercharger.
DC fast charging only
The GM NACS DC adapter is not for Level 2 Tesla wall connectors or destination chargers. It’s engineered for DC fast‑charging only. For Level 2, you’ll still use J1772 (or a J1772 adapter) with non‑Tesla public stations or home equipment.
Which GM EVs work with a Tesla adapter?
GM has stated that its NACS DC adapter is compatible with basically all modern GM EVs that use a CCS fast‑charge port, including several discontinued models. That means most Ultium‑based EVs as well as the Bolt family can charge with Tesla Superchargers, as long as you have the adapter and a compatible station.

Always confirm compatibility in your GM owner’s app or vehicle manual before using any adapter.
Check your exact vehicle
Compatibility is broad, but always confirm in your GM mobile app or owner’s manual. If you’re buying used, ask the seller whether the adapter is already linked to the vehicle’s profile and whether any software updates are pending.
GM Tesla adapter cost and how to buy one
Unlike some brands that mailed free adapters, GM treats the NACS DC adapter as an accessory. In the U.S., the MSRP has typically been around $225, plus tax and shipping. You order it through your GM brand mobile app rather than a generic online store, so it’s tied to your specific vehicle and profile.
How to order a GM Tesla adapter from your phone
1. Open your GM brand app
Launch myChevrolet, myGMC, myBuick, or myCadillac and make sure your EV is added to your account and connected.
2. Set up public charging & payment
In the charging or public charging section, add a valid payment method. This is what GM will use for Supercharger sessions and the adapter purchase.
3. Find the NACS adapter section
Look for a banner or menu item related to Tesla Supercharger access or a “NACS DC adapter” accessory within the app’s store or charging options.
4. Place your order
Select the adapter, confirm your shipping address, and complete checkout. Keep an eye on any estimated ship date or back‑order notice.
5. Register it to your vehicle
When it arrives, follow any instructions in the box or app to link the adapter to your vehicle profile if required.
Watch for back‑orders
Demand for NACS adapters has been high across all brands. If your GM Tesla adapter is back‑ordered, avoid overpaying for unverified third‑party adapters as a quick fix, especially if you rely heavily on DC fast charging.
How to use the GM Tesla adapter: step‑by‑step
Using a GM Tesla adapter at a Supercharger is straightforward once you’ve done it once or twice. The key is to set everything up before you arrive at a busy station so you can plug in and go with minimal fuss.
Step‑by‑step: Charging your GM EV at a Tesla Supercharger
1. Confirm compatibility in your app
Use your GM app’s charger filters to show Tesla Superchargers that are compatible with non‑Tesla EVs. Not every Supercharger site will work with your GM.
2. Pre‑condition your battery (if available)
If your EV supports battery pre‑conditioning, navigate to the charger in your in‑car nav so the pack can warm or cool for faster charging.
3. Park carefully
Supercharger cables are designed for Tesla charge‑port locations. With a GM EV, you might have to back in or park slightly off‑center so the cable reaches without straining it.
4. Attach the adapter to the Tesla connector
Before plugging into the car, firmly connect the GM NACS adapter to the Supercharger cable until it clicks. Treat it as one solid unit.
5. Plug into your GM EV
Insert the CCS end of the adapter into your EV’s DC charge port. Wait a moment; the lights on your car and the charger should indicate a handshake.
6. Start the session in your GM app (or automatically)
Many sessions will start automatically once everything authenticates. Your GM app should show live charging data and handle payment.
7. End the session and disconnect
When you’re done, stop charging from your car or app, press the handle button, remove the adapter and cable together, then detach the adapter from the cable.
Keep the adapter on the cable
In practice, it’s often easier to leave the adapter attached to the Tesla connector for the entire session. Just be sure to remove it and stow it safely before leaving the stall.
Where you can charge a GM EV at Tesla Superchargers
When GM and Tesla flipped the switch in September 2024, they opened up access to more than 17,800 Tesla Supercharger stalls across the U.S. and Canada for GM drivers using a NACS adapter. That number continues to evolve as Tesla upgrades older sites and opens new ones.
Three ways to find compatible Tesla Superchargers
Use multiple tools for the best picture of what’s available on your route.
GM brand apps
myChevrolet, myGMC, myBuick, myCadillac integrate Tesla Superchargers directly:
- Filter for compatible NACS DC stations
- See real‑time status and power levels
- Start and pay for sessions in‑app
In‑car Google Maps (when equipped)
Many GM EVs with Google built‑in can filter for NACS DC fast chargers right on the center screen:
- Search along your route
- Send navigation to the station
- Trigger battery pre‑conditioning
Third‑party apps and maps
Tools like PlugShare, Chargeway, A Better Routeplanner and others can:
- Show recent user check‑ins
- Highlight compatible Tesla sites
- Help you cross‑check reliability
Not every Supercharger is open
GM EVs can generally use V3 and newer Tesla Superchargers, but some locations remain Tesla‑only. Your GM app will usually hide incompatible sites or clearly mark them, so rely on it rather than assuming any red pin is fair game.

Charging speeds and limits with the GM NACS adapter
The GM Tesla adapter itself is engineered to handle high‑power DC fast charging. In practice, your charge speed is limited by three things: the Supercharger hardware, your EV’s battery and software, and real‑time conditions like pack temperature and stall sharing.
What the Supercharger can deliver
- Most open‑access sites are V3 Superchargers rated up to 250 kW per stall.
- Some locations derate power during heavy use or hot weather.
- If two vehicles share power hardware, your peak may be lower.
What your GM EV can accept
- Each GM EV has a maximum DC power rating (often 100–350 kW).
- Charging slows above ~60–70% state of charge to protect the battery.
- Cold batteries or repeated fast‑charges in a day can cut power further.
Aim for 10–60% on road trips
For the fastest miles per minute, plan your Supercharger stops so you arrive with 10–20% battery and unplug around 60–70%. Topping all the way to 100% can take nearly as long as the first half of the session.
Safety warnings and common mistakes to avoid
Adapters add convenience but also another point of failure. Treat your GM Tesla adapter like a critical piece of high‑voltage equipment, not just another accessory rolling around the trunk.
- Never use the DC adapter on Level 2 Tesla wall connectors. It’s not built for AC use.
- Don’t defeat physical interlocks or latches. If the adapter or connector won’t click into place, stop and inspect it.
- Avoid excessive tension on the cable. Parking too far away or stretching the cord can damage both the station and your adapter.
- Don’t fast‑charge a damaged battery. If your EV has recent collision damage or pack warnings, resolve those before DC fast charging.
- Store the adapter in a padded, dry spot. Keep it away from sharp objects and moisture in the cargo area.
When to stop immediately
If you smell burning, see smoke, or your EV throws repeated charging faults when using the adapter, stop the session immediately, move the vehicle to a safe area, and contact roadside assistance or your dealer before attempting another DC fast‑charge.
GM EVs with built‑in NACS ports (no adapter needed)
GM has committed to building its future EVs with the North American Charging Standard (NACS) port directly on the car. That means no adapter needed for Tesla Superchargers, just plug in with the native connector. For these vehicles, a CCS adapter may be offered instead so you can still use legacy CCS networks.
Exact timing and model lists evolve, but broadly, you can expect 2025‑and‑newer GM EVs, including upcoming versions of the Equinox EV, Silverado EV, GMC Sierra EV, and Cadillac Optiq/Optiq‑V, to move toward native NACS ports. If you’re shopping new or late‑model used, check the charge port shape in photos or ask the seller which standard the vehicle uses.
A plus for future resale
An EV with a native NACS port, or one that includes a GM Tesla adapter, will generally be easier to live with and easier to sell later. At Recharged, we highlight NACS and adapter compatibility in listings so you can quickly see how easy it’ll be to fast‑charge your next EV.
GM Tesla adapter vs. third‑party options
Type "GM Tesla adapter" into a search bar and you’ll see a wave of third‑party CCS‑to‑NACS gadgets promising high power at tempting prices. Some will be fine. Others may be under‑tested, poorly sealed, or simply incompatible with GM’s evolving software and safety requirements.
GM‑approved adapter vs. third‑party adapters
Why it usually pays to stick with the official hardware for DC fast charging.
GM‑approved NACS DC adapter
- Designed and validated specifically for GM EVs and supported networks.
- Backed by GM’s documentation and evolving software updates.
- Clearly supported workflow in GM apps and at Tesla Superchargers.
- Price is known and reasonable versus risk of damage or warranty issues.
Third‑party CCS–NACS adapters
- Specifications may be unclear; power ratings can be optimistic.
- Limited or no testing with your exact GM model and software version.
- Potential warranty headaches if something fails during a DC fast‑charge.
- Safer to stick to Level 2 use unless specifically approved for DC.
When a third‑party adapter might make sense
If you occasionally need a Tesla Level 2 destination charger at a hotel, a third‑party J1772–Tesla adapter can be reasonable. But for DC fast‑charging, use the GM‑approved NACS DC adapter whenever possible.
Tips for road trips and real‑world usage
Once you’re comfortable with the GM Tesla adapter, it becomes just another part of your charging toolkit. The difference is that now you can plan routes that lean on Tesla’s dense highway network plus legacy CCS stations, choosing whichever is most convenient on a given day.
Real‑world tips for using Tesla Superchargers with a GM EV
Carry both options
Keep your GM Tesla adapter in the car at all times, but don’t abandon CCS networks. In some regions, CCS stations are closer to amenities or offer better pricing.
Favor pull‑through or wide stalls
With a non‑Tesla, you often need a little extra maneuvering room to line up the port. Look for end stalls or wider spots when towing or driving a larger SUV or truck.
Check recent user reports
Before banking on a new‑to‑you Supercharger with your GM EV, scan recent check‑ins on PlugShare or similar apps to confirm that non‑Tesla vehicles are charging successfully.
Mind idle fees
Tesla’s idle fees can kick in if you stay parked after charging completes. Set an alarm on your phone so you can move promptly when the session ends.
Keep your adapter clean
Dust, sand, and moisture are the enemy of high‑voltage connectors. Wipe the adapter ends occasionally and keep the protective caps or pouch on when not in use.
Plan around your battery health
Frequent DC fast‑charging is fine, but if you’re shopping a used GM EV, look at the battery health report. Recharged’s Score Report gives you an objective look at pack condition before you commit.
