3.3 ft USB4 Cable for Thunderbolt 3/4

This 3.3 ft USB4 cable delivers 40 Gbps data transfer and up to 240 W power delivery. It connects Thunderbolt 3 and Thunderbolt 4 devices using USB-C male connectors on both ends. The cable suits professionals moving large media files between compatible workstations and peripherals.

Suits Thunderbolt workflows; not for longer runs

The cable fits users who need maximum 40 Gbps bandwidth and 240 W charging for Thunderbolt 3 or 4 docks, drives, or displays. Buyers who need a cable longer than 3.3 ft for distant device placement should look at a different length. Passive construction limits reach at full speed.

40 Gbps USB4 bandwidth decides fit

The single specification that determines compatibility is the 40 Gbps USB4 data rate. Both host and peripheral must support this speed to achieve the rated throughput. If either end operates at a lower standard, the link will fall back to the slower speed.
