Superchargers can charge at up to 120,000 watts - and most installed superchargers a 160,000 watt pairs (160,000 watts shared between two stalls) - since charging tapers while the cars are charging load shifts from one car to other…
color me jealous of your area - the 30 minute limit SUCKS!In my area, the EVgo DCFC chargers don't have the 30 minute limit, but I think they're newer installations.
