All-purpose USB4 cable for high-speed workflows

This LUOM TJ-A323 cable combines 40Gbps data transfer, 100W power delivery and 8K@60Hz video in a single 3.3FT USB C to USB C link. It targets creators and professionals who need one cable for docking stations, external SSDs and high-resolution displays.

40Gbps headroom with 100W ceiling

The USB4 Gen 3x2 connection moves large project files at up to 2.8GB/s read and 2.1GB/s write, while PD 3.1 Extended Power Range supplies up to 100W (20V/5A) for 16-inch laptops. Bandwidth drops to Thunderbolt 3 speeds on older ports, and 100W charging requires a matching EPR charger and device.

Reversible connectors simplify daily use

Bi-directional USB C male ends plug in either orientation, reducing wear on ports during frequent docking. The cable carries no active electronics, so length is fixed at 3.3FT and it cannot extend beyond that distance without signal loss.

Questions about this item

Will this USB4 cable work with my older Thunderbolt 3 laptop and dock?

Yes, the cable is backwards compatible with Thunderbolt 3 devices and supports up to 40Gbps data transfer and 100W power delivery when both ends support those speeds.

How can I verify the cable is delivering the full 100W charge to my MacBook Pro 16''?

Use a USB-C power meter inline or check the macOS System Information power section; it should show 20V at 5A when paired with a 100W EPR PD 3.1 charger under full load.

Does the 3.3FT box include a charger or do I need to buy a 100W PD 3.1 brick separately?

Only the USB-C to USB-C cable is included; a 100W EPR PD 3.1 charger must be purchased separately to reach the maximum 100W (20V/5A) power delivery.
