You should see that it is either 48 amps or 72 amps. 48 amp was the standard when refresh was introduced but with an option to upgrade it at purchase to 72 amps. There was then a period when Tesla made the 72 amp charger standard on some models, I believe this was mainly the 100D or P100D models. I don't recall that ever applied to the 90Ds, and was not too long until Tesla reverted to 48 amp as the standard for everything.
So most likely you'll see it's 48 amps with 72 amps being much less common.
