Hey there, fellow EV enthusiast! Are you looking to expand your charging options and tap into Tesla's extensive Supercharger network with your General Motors (GM) electric vehicle? You've come to the right place! Buying and using a GM-approved Tesla adapter, specifically the NACS DC adapter, is a straightforward process that unlocks a world of convenience. Let's dive in!
Step 1: Confirm Your GM EV's Compatibility
Before you do anything else, let's make sure your GM EV is ready for this upgrade. While GM is transitioning to NACS ports in newer models (starting around 2025-2026), most current GM EVs are equipped with a CCS1 (Combined Charging System) inlet. The NACS DC adapter is specifically designed to bridge this gap, allowing your CCS1-equipped GM EV to connect to Tesla's NACS Superchargers.
Check your vehicle's charging port: Take a quick peek at your EV's charging port. If it's a CCS1 port, you're good to go with the adapter.
Software Update: Some older Chevrolet Bolt EV models (19MY and 20MY) might require a software update to enable Supercharger access. GM will usually contact owners if this is needed.
Step 2: Acquire Your GM-Approved NACS DC Adapter
This is the crucial piece of hardware! GM strongly advises using only their approved NACS DC adapter to prevent potential damage to your vehicle and to ensure warranty coverage.
Sub-heading 2.1: Where to Buy
You have a few convenient options for purchasing the official GM NACS DC adapter:
Through your GM Vehicle Mobile App: This is often the most direct and recommended method. Open your myChevrolet, myGMC, or myCadillac mobile app (depending on your vehicle brand).
Navigate to the "Settings" section.
Select "Public Charging."
Look for the "Tesla Supercharger" section and select the "Order Adapter" text.
Follow the prompts to input your EV's VIN and choose your delivery option (ship to home or pick up at a local dealership).
GM Accessories Websites: You can also purchase the adapter directly from the official Chevrolet Accessories, GMC Accessories, or Cadillac Accessories websites.
Your Local GM EV Dealer: If you prefer an in-person purchase or have questions, your nearest GM EV dealership's parts department can also help you acquire the adapter.
Sub-heading 2.2: Understanding the Cost
The MSRP for the GM-approved NACS DC adapter is typically around $225 USD. Keep in mind that prices might vary slightly, and some dealerships or promotions might offer different pricing.
Step 3: Set Up Your GM Vehicle Mobile App for Public Charging
The GM mobile app is your command center for accessing and paying for Supercharger sessions.

Your GM mobile app is your best friend for locating available Superchargers.
Navigate to the "Map" tab within your app.
Use the search bar to search for Tesla public charging stations. The app integrates the Tesla Supercharger Network, showing real-time availability.
Alternatively, if your vehicle has Google built-in compatibility, you can use Google Maps on your center display.
Select the "Charging Stations" icon under the search bar.
In the charging stations list, select the "Filters" icon.
Navigate to "Compatible Plugs" and toggle NACS to "On." This will show NACS-compatible stations in your search results and EV trip plans.

Prepare: Once you arrive at the Supercharger station and have identified an available stall, have your GM-approved NACS DC adapter ready.
Connect the Adapter: First, plug the NACS DC adapter into the Tesla Supercharger cable's handle. Ensure it's firmly attached and the latch is in place.
Plug into Your Vehicle: Next, plug the adapter (with the Tesla cable attached) into your GM EV's CCS1 charging port. You should feel a click as it secures.
Initiate Charging via App: Within your GM vehicle mobile app, select the specific Tesla Supercharger you're at from the "Charge Management" section. Tap to begin charging.
Monitor and Pay: Charging should begin automatically within a few seconds. You can monitor the charge status through your app. Once complete, you'll receive an email receipt for your session.
Sub-heading 4.2: Important Safety and Usage Tips
Always inspect the adapter for any damage (cracks, fraying) before each use. Do not use a damaged adapter.
Do not attempt to open, disassemble, or modify the adapter. It's not user-serviceable.
Do not disconnect the adapter while charging your vehicle.
When unplugging, stop the charging session first using your vehicle's infotainment system, the mobile app, or the charging station itself.
Unlock your vehicle's charge port.
Remove the adapter and the Tesla handle as one unit from your vehicle by pressing the metal CCS1 latch.
Then, remove the NACS DC adapter from the Tesla charging handle by pressing the NACS latch on the adapter.
Return the Tesla charging handle to its dock.
Store your adapter safely when not in use to prevent corrosion or damage.
Step 5: Enjoy the Expanded Charging Network!
With your GM-approved NACS DC adapter, you now have access to over 17,000 Tesla Superchargers in the U.S. and Canada, significantly expanding your fast-charging options. This is a game-changer for road trips and daily charging convenience!
