What this cable does and who it suits

The LUOM USB4 cable carries up to 240W of power and 40Gbps of data between any two USB-C ports. It supports Thunderbolt 3 and 4 hosts, making it a single lead for charging a 16-inch MacBook Pro at 140W, driving an 8K display at 60Hz or linking an eGPU enclosure to a laptop.

Practical limits of the USB4 Gen 3x2 interface

The 40Gbps ceiling is only reached when both ends implement USB4 Gen 3x2; older USB 3.2 or USB 2.0 devices will fall back to their own slower rates. Video output tops out at 8K 60Hz for a single screen or dual 4K with two cables. The 240W figure requires a PD 3.1 EPR charger and a device that can accept 48V at 5A.

Build, connectors and daily use

A sleeved jacket protects the 1-metre grey cable from abrasion while staying flexible enough for desk routing. Reversible USB-C male plugs insert either way up, and the bi-directional design means power and data flow in either direction without re-plugging. It works with phones, docks, laptops and gaming PCs alike.
