The early Model S had a single 40 amp charger or dual for 80 amps combined.Didnt early ones have a single/dual 40A for 40A or 80A? It’s why Gen 2 HPWC could need as high as 100A breaker for 80A charging. Or did they change that from S to X? Either way, 72A is 50% faster than 48A hence “supercharger.”

UPGRADING SINGLE to DUAL/ TWIN ONBOARD CHARGERS, possible? how? prog?
I have an early 2016 P90DL that has only the single 40 charger onboard. I want to either ADD a secondary charger for the "dual charger" to charge at 80A from HPWC. OR upgrade to the single 72A charger... are either of these possible? If I go the dual charger route, do I need to buy a matched/...teslamotorsclub.com
Model X was the first to go with one unit that was 48 or optional 72 amp... Later the 72amp option was dropped. Refresh Model S (after they got rid of the nose-cone) was the first S to use 48 or 72 amp chargers. Obviously they dropped 72amp on that as well. 3/Y never had anything but 32 or 48 amp depending on which particular model you got. Cheapest base models were always 32amp.
/edit Unlike the old single 40 amp chargers which could have a second one retrofitted on to go to 80 amp charging, Tesla never offered a upgrade path for 48 amp S/X to go to 72amps.
