The Tesla adapter is superior in almost every way to CCS. IMHO, everyone should use it. The CCS plug, particularly the US variant, is considerably worse from a usability perspective. (It’s also more complicated and heavy and therefore more expensive to make.)

Standardizing on the US CCS plug would be a mistake that would cement a disadvantage for EVs. If we’re going to insist on a standard plug, I’d prefer the Tesla plug but even the European CCS plug wouldn’t be so bad. Look at the size difference, and tell me that lifting a much heavier plug won’t have a usability impact especially for people with a small frame or physical disability.
