It is time to upgrade Kingman. Thursday night 1 was inop and the other 5 were operating at reduced capacity. Max 60Kw on one paired with inop charger the rest of us were at 18 to 48Kw. I have had my S for 3 years with 98000 miles and this is the first time I have had to wait for a supercharger. 5 charging and 7 waiting in line.
