In mid-2023, just as it seemed like the North American auto industry had settled on CCS1 as the default fast-charging plug, everything upended as Ford, then General Motors, then everyone else announced they were adopting the North American Charging Standard.

Originally developed by Tesla, NACS has a different plug but uses the same electronic communication protocols as CCS, and adoption of NACS thus makes all those non-Tesla electric vehicles compatible with the extensive Tesla Supercharger network.

GM's existing EV drivers got access to those 17,000+ Superchargers last year—something that significantly upgraded the road-tripping experience with the Chevrolet Bolt, we discovered.

But the first GM EV with a native NACS port is still yet to reach the showroom. NACS will debut later this year in the 2026 Cadillac Optiq V, then we expect to see it next year fitted to the reborn Chevrolet Bolt, which has been dusted off and given a new lithium iron phosphate battery to go with the different charging port.

The first adapter that GM released, which cost $225, allowed CCS1-equipped EVs to connect to a NACS charger. But now, GM will have a range of adapters so that any of its EV customers can charge anywhere, as long as they have the right dongle.

For existing GM EVs with CCS1, there is a GM NACS DC adapter, just for fast charging. And for level 2 (AC) charging, there's a GM NACS level 2 adapter.

For the NACS-equipped GM EVs (which again are yet to hit the showrooms), there's a GM CCS1 DC adapter that will let those EVs use existing non-Tesla DC charging infrastructure, like Electrify America's 350 kW chargers. There is also a GM J1772 AC adapter, which will let a GM NACS EV slow-charge from the ubiquitous J1772 port. And a pair of adapters will be compatible with GM's Energy Powershift home charger, which lets an EV use its battery to power the house if necessary, also known as vehicle to home or V2H.

Although we don't have exact prices for each adapter, GM told Ars the range costs between $67 and $195.
