150kw is v2.
120kw is earlier v2 or v1 (I'm not 100% sure on this), but there are very few v1s out there
72kw are urban superchargers that do not split the charge, more info:
Tesla unveils new 'urban' Supercharger with a slower dedicated charge rate - Electrek
"Though the capacity of current Supercharger stations can be split between two stalls and therefore, depending on how many vehicles are at a Supercharger station, it can affect the charging rate.
Those new stations have a dedicated charging capacity of 72 kW per stall – meaning that the overall charging capacity of the station stays roughly the same as the non-urban Superchargers."
