A Tesla Supercharger is a 480-volt direct current fast-charging technology built by American vehicle manufacturer Tesla, Inc. for electric cars. The Supercharger network was introduced on September 24, 2012, with six Supercharger stations. As of February 18, 2021, Tesla operates over 30,000 Superchargers in over 2,564 stations worldwide (an average of 9 chargers per station). There are 1,101 stations in North America, 592 in Europe, and 498 in the Asia/Pacific region. Supercharger stalls have a connector to supply electrical power at maximums of 72 kW, 150 kW or 250 kW.

Tesla Model S was the first car to be able to use the network, followed by the Tesla Model X, Tesla Model 3, and Tesla Model Y. Some Tesla cars have free supercharging for life, some have 100–400 kWh per year, some have a single 100–400 kWh credit, and some have a monetary credit.
Any charges are automatically billed to the Tesla account the car is associated with. If the account does not have any credit, the charges are automatically billed to credit card on file for that account. Charges are ordinarily for the electricity used, but in some localities that is not allowed and Tesla charges for the time spent charging.
