Pretty much, but they are used to charge four passenger cars at a time. Needs the new connection standard.
With SuperCharger, SAE was so, so slow and Tesla needed to move on and start making chargers. This time with SEMI trucks, perhaps the makers can choose to standardize - and perhaps these companies will take Tesla seriously. Large Truck standardized chargers have obvious benefits for all. I look forward to the Hummer not working on MegaChargers. That would be a GM move. IMHO the Corvette C-8 maybe GM last good move. -- late by decades, perhaps better late than never? (pretty sure MBAs think dropping of Sedan Models, brilliant)
