The Brookshire Brothers charger is a DC Level 3 "fast charger". It'll charge about 10x faster than the J1772 destination chargers and about 5x faster than a Tesla destination charger.
There are several levels of DC chargers...50kW like the Brookshire Brothers location, 62kW at Mid-South, all the way up to 250kW and 350kW at the newer Electrify America chargers. The Tesla Superchargers are Buc-ee's and HEB in CS are 250kW. Your typical home "Level 2" charger is anywhere from 5kW to 11kW.
Level 1 = Regular 20A 110v AC outlet
Level 2 = 220v AC home and destination chargers (ranging from 20amps to 60amps)
Level 3 = DC Chargers (50kW to 350kW) that range from 400v to 800v
