What this cable is

The LUOM Thunderbolt 4 USB Cable is a 1.5 ft grey USB-C to USB-C cable built for Thunderbolt 4, Thunderbolt 3 and USB4 hosts. It suits professionals moving large project files between workstations, docks and high-speed storage, and creators driving 8K or dual 4K displays from a single port.

The spec that decides fit

This cable delivers 40 Gbps data throughput and 240 W (48 V / 5 A) power delivery, the highest rating in the current USB-C ecosystem. If your charger, laptop or dock cannot accept 240 W, the cable will simply negotiate the lower limit; if your host lacks Thunderbolt 4, Thunderbolt 3 or USB4 with DisplayPort Alt Mode, you will not reach the rated speed or video modes.

Capacity and headroom

At 40 Gbps the link can move a 2.5 GB file in roughly one second, with real-world reads up to 2.8 GB/s and writes up to 2.1 GB/s. It drives one 8K or 5K display at 60 Hz, or two 4K displays at 60 Hz when the host supports dual streams. The 1.5 ft length keeps signal integrity high but limits reach to desktop docking setups; longer runs will need an active or optical alternative.

Questions about this item

What does the 40Gbps rating mean when I am copying files between two Thunderbolt 4 devices?

The cable supports a theoretical maximum of 40Gbps, and real-world reads reach 2.8GB/s with writes at 2.1GB/s, so a 2.5GB file can move in about one second.

How does the Thunderbolt 4 interface limit the 240W charging claim in everyday use?

It delivers up to 240W at 48V/5A when both the charger and the device support that power level, otherwise it negotiates the highest rate both ends can handle.

Will the 1.5Ft length and USB C to USB C connectors fit between my laptop and a desk-mounted dock?

The cable is 1.5Ft long with male-to-male USB C plugs, so it suits tight desk setups where the dock sits close to the laptop.
