Chevrolet Silverado EV 2027: NACS charge port, adapter prices and charging speed

The 2027 Chevrolet Silverado EV is changing more than the shape of its charge port: the hardware its owner has to carry around is changing too. The native NACS inlet allows a direct connection to compatible Tesla Superchargers. But CCS1 stations and home units with a J1772 plug will now require an adapter — the burden simply shifts from one standard to the other.

GM Authority reports the arrival of NACS on the electric pickup. The previous NACS DC and NACS Level 2 adapters, meant for vehicles with a CCS1 port, are leaving the accessories catalog. In their place come the GM J1772 AC and GM CCS1 DC adapters, an adapter for the PowerShift home system and three ready-made charging packages.

The price list is already known: the J1772 AC adapter costs $67, the PowerShift AC adapter $116 and the CCS1 DC adapter $189. The departing NACS DC unit was the priciest of the lot at $275. The Charging Essentials package, which bundles the PowerUp 2 home charger with both adapters, costs $1155.

A new connector does not equal faster charging. For the 2026 Silverado EV, Chevrolet quotes DC stations of up to 350 kW and roughly 120 miles (193 km) of range added in ten minutes — a figure the versions with the larger battery packs can reach. The company has not officially disclosed the numbers for the 2027 model.

The full 350 kW is delivered today by Ionna, Electrify America and EVgo — precisely the CCS1 infrastructure that will now need an adapter. Most Superchargers are capped at 250 kW, and in one Silverado EV review the peak on an adapter never went past 175 kW. Direct access to the Tesla network makes plugging in easier, but on its own it does not speed charging up.

Today’s Silverado EV needs a GM-approved NACS DC adapter to plug into a Tesla Supercharger. In the next model year that adapter becomes redundant, yet an owner who regularly uses older CCS1 stations will need the reverse one. It is worth checking that it is in the truck before a long trip along a route where the infrastructure has not moved to NACS yet.

The connector is not the only change for the 2027 model year. The lineup shrinks from ten configurations to seven: the LT Max Range and both RST versions are gone, and the RST trim leaves the range for good. Production of 2026 trucks ends on October 9, the 2027 model year starts on October 12, and dealer orders open on August 6.

In parallel, GM is launching Energy Pass — a single point of access to charging networks straight from the myChevrolet, myCadillac and myGMC apps, with no separate account for each operator. At launch it covers Tesla Supercharger, Ionna and Electrify America, with ChargePoint and EVgo to follow — together they account for almost 70% of DC fast chargers in the United States. Plug & Charge at Superchargers is promised later.

We took a detailed look at the three GM charging packages for 2027 model year vehicles. They differ not in the specs of the vehicle but in the mix of adapters and home equipment. Another example of the same switch is the Chevrolet Blazer EV 2027 with its standard NACS port.

GM officially expects every new Chevrolet, GMC and Cadillac electric vehicle of the 2027 model year to have NACS by December 2026. For a Silverado EV buyer, the choice of adapter should now depend on the home charger and the stations along the usual routes, not just on access to the Tesla network.
