Both of the other answers are incomplete: In Europe, where there is only one DCFC standard, Tesla uses a standard connector but only allows Tesla cars to charge at superchargers (there is no way for drivers of other cars to pay or be billed for use of the station). In the USA, where both CCS and Chademo are standards, Tesla uses their own proprietary connector (which is substantially more ergonomic than either CCS or Chademo). Tesla sells a Chademo adapter and a third party sells a CCS adapter, so Tesla cars can use third-party DCFC stations. In both cases, only Tesla cars can use Tesla Superchargers.
