Thunderbolt 3 to Thunderbolt 2 Adapter - Non-Reversible, Black, 20Gbps, Windows/Mac (TBT3TBTADAP)

This adapter allows users to connect Thunderbolt 2 or Thunderbolt 1 devices to a Thunderbolt 3 laptop or desktop. It is specifically designed for users who have older peripherals but want to use them with newer Thunderbolt 3 devices without needing to replace their existing gear. The adapter is non-reversible, meaning it has a specific orientation for insertion, and it supports data transfer speeds of up to 20Gbps for Thunderbolt 2 devices and 10Gbps for Thunderbolt 1 devices. It is not compatible with standard DisplayPort or Mini DisplayPort monitors, nor does it work with Thunderbolt 4 computers.

The adapter is certified for use with Thunderbolt 3 laptops from major brands like Apple, Dell, Lenovo, and HP. It requires the host device to have a Thunderbolt 3 port, which is typically identified by a lightning bolt icon. The adapter is bus-powered, meaning it draws power from the connected device rather than requiring its own power source. It provides up to 12W of power to connected peripherals, which is sufficient for many external storage devices and displays. However, it cannot power devices that require more than this amount.

The design includes an 8-inch built-in cable, making it more convenient than a separate cable and adapter setup. The physical connector is a Mini DisplayPort type, but it does not support DisplayPort signals. This means it cannot be used with standard DisplayPort monitors or other non-Thunderbolt peripherals. The black color and compact form factor make it suitable for both desktop and laptop environments, though its non-reversible design may require careful alignment during insertion.

The adapter is ideal for professionals who rely on older Thunderbolt peripherals such as external storage drives or high-resolution displays. It allows them to continue using these devices with newer laptops that have Thunderbolt 3 ports. However, users should be aware that it does not support bidirectional connections and will not work with Thunderbolt 4 systems or non-Thunderbolt 3 USB-C laptops. It is also not suitable for connecting to standard DisplayPort monitors.
