I know the ABB EVgo chargers are classified as 125A 50kW chargers so I feel pretty condifent I will get ~45kW on those. There was some other model charger, I am not sure who makes it but it has a big touch screen, that only did 100A. I have just been checking the pictures on plugshare and if I see that big screen, I skip that charger.
I have also been avoiding the chargepoint network since they are littered with 24kW chargers and I do not feel like picking through each site to find a 50kW (needle in a haystack).
