Backward-compatible Thunderbolt adapter

The StarTech.com TBT3TBTADAP connects first-generation Thunderbolt and Thunderbolt 2 peripherals to a Thunderbolt 3 host. It is aimed at users who need to keep existing storage, docks or displays working after upgrading to a USB-C Thunderbolt 3 computer.

Male USB-C to female 20-pin connection

The adapter presents a 24-pin Thunderbolt 3 male plug on one end and a 20-pin Thunderbolt 2 female receptacle on the other. Its .5 ft length keeps the link short for signal integrity while freeing the host port from bulky legacy cables.

Bus power and Thunderbolt certification

The unit supplies bus power so compatible portable drives or accessories operate without an external supply. Thunderbolt certification confirms the electrical and protocol implementation meets the spec for reliable device enumeration.

Questions about this item

What is the maximum cable length before signal loss becomes an issue?

The adapter cable measures .5 ft, keeping the Thunderbolt 3 to Thunderbolt 2 link within the short passive range where signal integrity is maintained.

Does the adapter generate noticeable heat or draw extra power during continuous operation?

It is a passive Thunderbolt Certified adapter with no active electronics, so it adds no measurable heat and draws only the bus power required by the connected Thunderbolt 2 device.

Which port must my computer provide for this adapter to function?

Your computer needs a Thunderbolt 3 USB-C port with 24-pin male connector to mate with the adapter's Thunderbolt 3 plug.
