Take a look on ChargePoint, they list the voltage and amperage for each QC. The voltage they list on ChargePoint (500v) is too optimistic, the real voltage will be around 400v or so. Multiply that by the amperage to get the output in watts. The station at Big Y is listed as 62a, so 24.8kW, or we can round up to 25kW. I've seen a lot of stations on ChargePoint listed at 75a (30kW), 100a (40kW), and then the max is 125a (50kW). Even some of the stations at Nissan dealers are limited to less than 125a. There's a QC in Queens, NY that is limited to just 60a, but I can't complain because that particular unit was originally limited to something like 25a if I'm remembering correctly!
