Unless you were living under a rock or just got into EVs recently, you probably know all about the industry moving from CCS1 to Tesla’s NACS standard in North America. Starting with Ford, nearly every major automaker selling or planning to sell EVs in the United States decided to move to Tesla’s plug, largely due to reliability problems from CCS charging providers.
Technically, aftermarket adapters from companies like A2Z and Lectron aren’t welcome on the network, but the fine print that prohibits that is likely more of a “cover your ass” kind of thing. The leading aftermarket adapters are either UL-rated or are built to pass UL testing and are just waiting for certification. But, cheaper adapters that you might find on Amazon or Wish are not built to specification and could pose a danger.
This situation will not change when NACS-native vehicles from other manufacturers come out next year, as NACS is only a physical standard, and relies on CCS communication protocols for signaling. This means that until Tesla replaces V2 stations with newer hardware, they will only be accessible to Tesla vehicles.
