Use legacy Thunderbolt devices with your new Thunderbolt 3 computer. With this adapter, you can connect newer Thunderbolt 3 computers to legacy Thunderbolt devices, such as external hard drives, displays, and older Thunderbolt capable Mac computers. Newer Thunderbolt 3 computers include the latest models of Dell Precision and Dell XPS.

Because this adapter is backward compatible, you can connect to first-generation Thunderbolt devices at 10Gbps speed. With Thunderbolt 2 devices, you can connect at 20Gbps. The adapter supports bi-directional data transfers and simultaneous power delivery for bus-powered devices.

You can also set up 10Gbps peer-to-peer networking between older Thunderbolt laptops and newer Thunderbolt laptops. This is perfect for setting up small workgroups and sharing peripherals such as printers and storage or quickly migrating data to a new computer.
