I've seen 37 to 38 kWh on my 2015 e-Golf SEL, the few times I've used DCFC in the 20 minute charge version... by 17 18 minutes, it's slowing down considerably.
The ChargePoint 100 units I've seen, at best, 20.5 kWh on the 24 kWh version. It will take you 50 minutes to get to 80% and probably 60 minutes to get to 90% SOC on these models. The ChargePoint 100's are a LOT easier on the battery pack, in terms of not generating too much heat inside the battery pack.
