One Cable for Charging, Video and Data

The LUOM TJ-A323 is a USB4 cable with USB-C male connectors on both ends. It handles up to 100W power delivery, 40Gbps data transfer and 8K video at 60Hz. The cable works with Thunderbolt 4 and Thunderbolt 3 hosts, plus earlier USB standards. Buyers who need longer reach or angled connectors will need a different product.

Thermals Noise and Power Draw

Passive copper construction means no fan noise and no active cooling requirement. The cable delivers up to 100W at 20V/5A when paired with a compatible charger and device. Power loss along the 3.3FT length stays within USB4 specification limits. No external power adapter is required for operation.

What the Bundle Changes

The package contains only the cable itself. No dock, charger or video adapter is included. Full 40Gbps throughput, 100W charging and 8K@60Hz output each depend on the host, peripheral and charger all supporting those capabilities. Dual 4K displays require two separate cables.

Questions about this item

How do I connect the USB C male ends to my laptop and dock without forcing the reversible plug?

Align the oval USB C male connector with the port on each device and insert gently; the reversible design fits either way up, so no force is needed.

Will the 100W PD 3.1 charging capability degrade over time with daily use?

The cable is rated for 100W (20V/5A) power delivery and maintains that specification throughout its service life; no periodic recalibration or replacement is required.

At what point does the 40Gbps data rate drop during a long file transfer?

Sustained transfers run at the rated 40Gbps limit; the cable does not throttle below that speed under normal operating temperatures.
