USB4 Gen 3x2 40 Gbps cable

The SMUGDESK USB4 cable delivers up to 40 Gbps data transfer and 240 W power delivery over a 5 ft USB C to USB C connection. It supports the USB4 Gen 3x2 standard and PD 3.1 Extended Power Range with 48 V maximum voltage. Backwards compatibility covers 180 W, 140 W, 100 W and 60 W profiles. The bi-directional, reversible connectors suit laptops, docks, hubs and recent smartphones.

Users needing 40 Gbps and 240 W in one cable

Creative professionals moving large video files between USB4 Gen 3x2 devices gain the full 40 Gbps throughput. Owners of 140 W or 240 W PD 3.1 chargers can power 16'' laptops at full load. Buyers who only need 10 Gbps or 100 W charging will find cheaper cables that meet those lower requirements. The 5 ft length may limit setups that require longer runs.

40 Gbps USB4 Gen 3x2 data rate

This single specification decides whether the cable matches the host and peripheral capabilities. Only USB4 Gen 3x2 ports can utilise the 40 Gbps ceiling; older USB 3.2 or USB4 Gen 2x2 ports will operate at their own lower limits. Verify that both ends of the link support USB4 Gen 3x2 before purchasing.

Questions about this item

How do I verify the cable is delivering 40 Gbps after connecting it?

Connect the cable between two USB4 Gen3x2 devices and run a speed test or transfer a large file; sustained throughput near 40 Gbps confirms the link is operating at full spec.

What comes in the box and is a charger included?

The box contains the 5 ft USB C to USB C cable only; a 240 W EPR PD 3.1 charger and a compatible device must be purchased separately to reach maximum power.

Should I choose the 5 ft or the 1.5 ft version for a desktop docking setup?

The 5 ft length gives more routing flexibility between a dock and a laptop on a desk, while the 1.5 ft version suits tight spaces or portable use.
