If you’re grabbing a new Rivian soon, you’ll now get the official Tesla NACS adapter with your vehicle upon taking delivery, maybe?
Rivian recently added the NACS DC Adapter as a line item on the vehicle spec sheet on Rivian.com, something that was not included before. While this doesn’t necessarily mean you’ll get it on the date of your delivery, it is now at least confirmed that you’ll get one without having to worry about submitting anything.
