Thunderbolt 4 (USB-C) ports

Use the Thunderbolt 4 (USB-C) ports to charge your computer, transfer data at Thunderbolt 4 or USB 4 speeds (up to 40 Gbit/s), and charge devices and accessories—such as an iPhone, iPad, or rechargeable trackpad or keyboard. You can also use this port to connect to an external display or projector.

If you have a device that doesn’t connect to this port, you can use an adapter to connect it. See the Apple Support article Adapters for the Thunderbolt or USB-C port on your Mac.
