Tesla Supercharging network is amazing and is clearly unmatched by any other equipment out there, including Electrify America. But, Tesla started rolling out their extensive network many years ago and in some cases, you may find yourself at an older location, with older equipment. Sometimes, that equipment is slower and not in ideal locations. Creepy or not, Tesla supercharging is a breeze in the Refresh Model X.
