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.
