All-purpose USB4 cable for 40 Gbps data

The LUOM TJ-A323 is a USB4 Gen 3×2 cable with USB-C male connectors on both ends. It delivers up to 40 Gbps bandwidth, 100 W Power Delivery 3.1 charging and 8K video at 60 Hz in a single 1.6 ft black cable. The bi-directional, reversible plugs work with Thunderbolt 3 and 4 hosts, recent laptops, tablets and phones that use USB-C.

Sustained 40 Gbps throughput

Real-world transfers reach 2.8 GB/s read and 2.1 GB/s write when paired with compatible NVMe enclosures or SSD drives such as the T7, T5 or Extreme Pro. The cable maintains PD 3.1 Extended Power Range at 20 V / 5 A during long copy sessions, so a MacBook Pro 16 can reach 60 % charge in 30 minutes while data moves at full speed. Dual 4K 60 Hz displays are supported when two cables are used.

Plug-and-play with reversible USB-C connectors

No drivers or firmware updates are required; the cable negotiates USB4, Thunderbolt 3/4 and PD 3.1/3.0 PPS automatically. The 1.6 ft length keeps the signal clean for 40 Gbps operation but limits reach between desk and dock. Buyers who need longer runs for monitor placement or rack mounting should look for an active optical alternative.

Built for NVMe enclosures.

The 40 Gbps link saturates current NVMe M.2 enclosures and external GPU docks, eliminating the bottleneck seen with 20 Gbps cables. It also carries enough power for 100 W laptops, so a single cable handles video, data and charging for a compact workstation. Users whose devices only support USB 3.2 Gen 2 or lower will not see the full speed or 100 W charging.

Questions about this item

Does the 1.6 ft cable get warm or draw extra power when running 100 W charging all day?

The cable is rated for 20 V / 5 A (100 W) PD 3.1 EPR, so it handles full power without overheating under normal use.

What charger and port does the buyer need to actually get 100 W and 40 Gbps from this cable?

A USB-C charger supporting PD 3.1 at 20 V / 5 A and a host port with USB4 Gen 3×2 or Thunderbolt 3/4 are required.

Will the cable work with an older laptop that only has USB 3.2 Gen 2 Type-C?

Yes — it falls back to the host’s maximum speed and power, so data runs at up to 10 Gbps and charging at the port’s PD limit.
