The adapter I have from Tesla, still unopened with my front license plate frame, is a j1772 to nacs plug. If I were to go road tripping, it would behoove me to get a CCS1-NACS adapter just in case. Tesla sells one for $175, and looks like Amazon has one for ~100.\nhttps:\/\/shop.tesla.com\/product\/ccs-combo-1-adapter From what I've seen on my two road trips north & south on the east coast, there seem to be more Tesla Supercharger stations than Fast DC chargers for CCS use, mainly Electrify America. Despite that, I've had no difficulty finding what I need. If & when I get access to all those Tesla stations, I'll benefit more than Tesla owners will from Electrify America stations. As usual, YMMV.\n\nThe first night I was in Winston-Salem, I charged up using my friend's 240V 50A tap that he had recently installed in his carport. (He doesn't own an EV now but got the tap while he had other electrical work done.) That was the first time I used the portable charger supplied with the EV.
