3.3-Foot USB4 Cable for Thunderbolt 3/4

This 3.3-foot USB4 cable connects Thunderbolt 3 and Thunderbolt 4 hosts with USB-C peripherals. It is built for professionals moving large project files and creators driving high-resolution displays. Backward compatibility extends to USB 3.2, 3.1 and 2.0 devices, so one cable covers legacy and current gear. The 100W power delivery charges laptops and powers bus-fed docks without a separate adapter.

Single-cable docking and display chain

Plug the cable between a Thunderbolt 3 or 4 port and a dock, storage array or monitor to carry data, video and charging simultaneously. It frees up extra ports by consolidating display output, 40Gbps data lanes and 100W power in one run. The host USB-C port must support DisplayPort Alternate Mode for video output to function. No additional drivers or power bricks are required for the cable itself.

8K@60Hz or dual 4K@60Hz headroom

The link sustains 40Gbps throughput, enough for an 8K@60Hz panel, a 5K@60Hz panel or two 4K@60Hz panels at once. High-refresh workflows can run a single 4K@144Hz display within the same bandwidth envelope. Charging tops out at 100W, so power-hungry workstations needing more wattage will still require their dedicated supply. Bandwidth scales down automatically when connected to USB 3.2, 3.1 or 2.0 ports.
