USB charging ports are power outlets using the universal serial bus (USB) female socket. USB is a plug-and-play interface commonly used for computers and handheld electronic devices. Depending on the application, USB can convey electricity, data, or both. Most new vehicles have at least two USB charging ports, usually in the front, but their number and locations can increase based on the size and amenity level of the model. USB-A has been the standard in cars, but many manufacturers have added USB-C ports or even replaced USB-A with USB-C.
For vehicles with one or no USB charging port, owners can purchase aftermarket modules that plug into the lighter, allowing devices to charge and connect with the car.
Some vehicles have illuminated USB charging ports for finding them in the dark, but that doesn’t mean you still won’t plug in the USB-A upside-down at first. See also Android Auto, Apple CarPlay, and wireless phone charging.
