The following diagram shows the main types of charging connectors. Both Level 1 connectors and the NEMA 14-50 connector (2nd Level 2 connector) are standard household US line power plugs. The other Level 2 connectors are the J1772 which is a universal connector that all EVs can use (Teslas come with the necessary adapter), and the Tesla connector.
Although there are two different standards for DC fast charging (Tesla and all others), as of 2026, the industry is shifting to the Tesla standard and many non-Tesla cars from GM, Hyundai, Kia, Toyota, Subaru, Nissan and others already come with a NACS (Tesla) port.
