All-Purpose USB4 Cable 40Gbps 100W

This USB4 cable connects USB-C devices for charging, data and video. It suits professionals moving large files between NVMe enclosures and laptops, and creatives driving high-resolution monitors. The bi-directional reversible connectors work with Thunderbolt 3 and 4 hosts.

Practical Limits of USB4 Gen 3x2

The cable delivers up to 40Gbps theoretical bandwidth, with real-world reads near 2.8GB/s and writes near 2.1GB/s. Video output reaches one 8K@60Hz display or dual 4K@60Hz displays. Power Delivery 3.1 EPR supplies up to 100W at 20V/5A. Actual speeds depend on host, device and cable quality.

Installation and Common Issues

Plug the USB-C male ends into compatible ports; no driver is required. Ensure both host and peripheral support USB4 or Thunderbolt 3/4 for full 40Gbps and 100W performance. Using older USB-C ports will reduce data rate and charging power. Dual 4K@60Hz requires two separate cables.

Questions about this item

Which LUOM TJ-A323 length should I pick for my desk setup?

The cable is supplied at 3.3ft (about 1 metre), a length that reaches from a laptop on a desk to a monitor or dock without excess slack.

What does the 40Gbps rating mean when I copy files to an NVMe enclosure?

Real-world reads reach 2.8GB/s and writes 2.1GB/s, so a 2.5GB file transfers in roughly one second with a compatible drive and host.

How does the USB4 Gen 3x2 interface limit charging and video?

The interface caps power at 100W (20V/5A) and drives one 8K@60Hz display or dual 4K@60Hz monitors when both host and display support the standard.
