Universal USB-C Cable

The LUOM TJ-A323 is a 3.3ft USB4 cable built for users who need one lead to handle charging, video and data across Thunderbolt 3, Thunderbolt 4 and USB-C devices. It delivers up to 100W power, 40Gbps bandwidth and 8K@60Hz display output in a single black male-to-male connection.

Replaces 60W and 80W Cables

This cable upgrades from earlier 60W and 80W USB-C leads by adding 100W Power Delivery with PD 3.1 support, doubling the data ceiling to 40Gbps and enabling 8K or dual 4K video. The jump is worth it when a laptop, dock or high-speed SSD demands the full 20V/5A profile or sustained 2.8GB/s read and 2.1GB/s write throughput.

Plug-and-Play With One Condition

Installation is straightforward: connect both USB-C ends and the cable negotiates the highest common standard automatically. The only common issue is video failure when the host port lacks DisplayPort Alternate Mode, so verify that the source device supports video over USB-C before troubleshooting the cable.
