USB 4 Cable Thunderbolt 4 40 Gbps 100W 3.3FT

This USB 4 cable is built for professionals who need maximum data throughput and power delivery over a single connection. It suits creators moving large video files, developers using external GPU enclosures, and anyone driving high-resolution displays from a Thunderbolt 4 or USB4 port.

40 Gbps transfer and 100W PD 3.1 charging

The 40 Gbps bandwidth enables full-speed NVMe SSD performance and eGPU operation without bottlenecks. PD 3.1 Extended Power Range delivers up to 100W so a compatible laptop can charge from zero to sixty percent in roughly thirty minutes while the cable simultaneously carries video and data.

Plug-and-play with Thunderbolt 4 and USB4 hosts

Both ends are USB-C so installation is a simple insert; no drivers are required on supported operating systems. The most common issue is using a port that only supports USB 3.2 or DisplayPort alt mode, which limits speed to 10 or 20 Gbps and may restrict charging to lower wattages.

Questions about this item

Does the 100 W PD 3.1 charging require any periodic connector maintenance?

The USB-C connectors are rated for thousands of insertions; keeping the ports clean and avoiding strain on the 3.3 ft cable is the only upkeep needed.

What limits sustained 40 Gbps transfers during long sessions?

Thermal throttling in the host or SSD enclosure typically caps throughput before the cable itself becomes the bottleneck.

How warm does the cable get when delivering 100 W continuously?

The cable meets USB-IF heating limits for 20 V / 5 A operation, so it stays warm but within spec during all-day charging.
