For a long time, one of the biggest knocks against buying an electric vehicle that wasn’t a Tesla was charging infrastructure. Tesla owners had their Supercharger network—fast, reliable, and seemingly everywhere—while everyone else pieced together road trips using a patchwork of third-party stations that varied wildly in reliability.
- All current GMC EVs can access Tesla’s Supercharger network using a GM-approved NACS adapter that costs $225.
- DC fast charging can add around 100 miles of range in about 10 minutes, with costs typically ranging from 40 to 70 cents per kilowatt-hour.
- Starting in 2025, new GMC electric vehicles will come with built-in NACS ports, eliminating the need for an adapter.
Why This Matters for GMC EV Owners
GM adopted the North American Charging Standard, which is the same connector Tesla uses. That decision opened up the largest and most reliable fast-charging network in North America to every GMC EV owner. Whether you’re driving a Sierra EV or a HUMMER EV, you now have access to thousands of charging stations that were previously off-limits.
Before this change, electric vehicle owners who didn’t drive Teslas had to rely on a mix of third-party charging networks. Some worked great. Others were slow, broken, or just plain hard to find. Tesla’s network isn’t perfect, but it’s consistent, and that consistency makes a huge difference when you’re planning a long drive.
What You Need to Get Started
Current GMC electric vehicles use a CCS charging port, which means you’ll need an adapter to plug into Tesla Superchargers. The GM-approved NACS DC adapter costs $225 and can be ordered through the myGMC app, the GMC Accessories website, or directly from us at the dealership.
Once you have the adapter, you’ll need to set up Tesla Supercharger access in the myGMC app. Open the app, go to Settings, then Public Charging. You’ll activate access and add a credit card for payment. No monthly fees, no subscriptions. You pay for what you use, and that’s it.
When you arrive at a Supercharger, plug the adapter into the Tesla cable, connect it to your vehicle, and start the charging session through the app. The app also shows you where nearby Superchargers are located and whether charging stalls are available, which is helpful when you’re on a road trip and don’t want to waste time hunting for an open spot.
Charging Speed and Costs
Most GMC EVs can handle DC fast charging speeds up to 150 kW. Under good conditions, that translates to about 100 miles of added range in roughly 10 minutes. Newer Supercharger stations don’t split power between neighboring stalls, so you’ll get full charging speed even when the station is busy.
Charging costs vary depending on where you are. Expect to pay somewhere between 40 and 70 cents per kilowatt-hour. You’ll get an email receipt after each session, so you can track your spending.
With access to Tesla’s network, GMC EV owners now have more than 231,000 public Level 2 and DC fast chargers available across North America. And starting next year, new GMC electric vehicles will roll out with NACS ports built in, so future buyers won’t need to mess with adapters at all.
Come See How It All Works
Reading about charging adapters and apps is one thing, but actually sitting in the vehicle and seeing how everything works is different. If you’re in the Texas Panhandle, stop by Greg Lair GMC in Canyon. Our team can show you how the myGMC app works, explain what you’ll need for charging, and let you explore vehicles like the Sierra EV or HUMMER EV up close.
We also offer a free Lifetime Powertrain Warranty on our vehicles, which is something worth considering when you’re making a decision this big. Check out our inventory at www.greglair.com, or just swing by if you’re in the area. We’re happy to answer questions and show you what electric driving looks like in a GMC.
