Rivian is the latest automaker to jump on Tesla’s charging standard, the North American Charging Standard (NACS). This comes just weeks after Ford and General Motors announced that their upcoming electric vehicles would have the proper equipment to recharge using Tesla Superchargers.

Current Rivian vehicles will get a NACS adapter. Future Rivian vehicles, including current R1T and R1S models, will ship with the NACS charge port as standard equipment.
