Published May 01, 2026

Thunderbolt 3 combines Thunderbolt, USB, DisplayPort and power via a single USB-C connector. Hardware commonly referred to as "USB-C devices" also will work with a Thunderbolt 3 port, but they will not be able to take advantage of the maximum speed provided by Thunderbolt 3 devices.

Also asked, can USB C connect to Thunderbolt?

You can plug a USB-C device and cable into a Thunderbolt 3 port whenever you want because Thunderbolt 3 fully supports USB-C. So a USB-C hard drive you have can be used in any of the Thunderbolt 3 ports on your MacBook Pro, or in the USB-C port on your 12-inch MacBook.

Also Know, can Thunderbolt 2 connect to USB C? No, at least not for just USB Type-C because USB Type-C doesn't support all of the protocols that Thunderbolt does and it doesn't have enough bandwidth to handle 6 Thunderbolt 2 devices at once.

Subsequently, one may also ask, does Thunderbolt 3 work with USB C?

All USB-C cables will work as Thunderbolt 3 cables as long as they are good quality cables. Thunderbolt 3 is backward-compatible with earlier versions of Thunderbolt, but due to the new port type, adapters are required to use legacy Thunderbolt devices.

What is the difference between USB C and Thunderbolt 3?

Thunderbolt 3 has the capabilities of USB-C, but USB-C does not have the capabilities of Thunderbolt 3. Thunderbolt 3 has greater performance when it comes to speed and video display. It's speed allows for quicker access more data when compared to USB-C. Thunderbolt 3 works at 40Gbps while USB-C works at 10 Gbps.
