LUOM USB4 Cable 40Gbps 240W

This LUOM USB C to USB C cable implements the USB4 Gen 3x2 standard for up to 40Gbps bi-directional data transfer and 240W power delivery at 48V. The 1.5FT grey cable carries male connectors on both ends and is compatible with Thunderbolt 3 and 4 hosts. It supports 8K 60Hz video output and works with external SSDs, eGPUs and USB-C docking stations.

Who This Suits and Who Should Look Elsewhere

Creators moving large media files between USB4 or Thunderbolt devices will use the 40Gbps link, and owners of 140W or 240W EPR chargers can power laptops at full speed. Buyers whose gear only reaches 10Gbps or 100W will not benefit from the extra headroom, and anyone needing a longer run than 1.5FT must choose a different length.

Deciding Specification — USB4 Gen 3x2 40Gbps

The single figure that decides fit is the USB4 Gen 3x2 40Gbps data rate combined with 240W extended power range. If the host, charger and peripheral all support that tier, the cable delivers full throughput and maximum charging; otherwise it falls back to the lowest common capability.

Questions about this item

Which charger must I already own to reach the 240W rating on this cable?

You need a 240W EPR PD 3.1 charger that can supply 48V at 5A, otherwise the cable will fall back to the lower power profile of the charger you use.

Will this cable still carry video and data if I plug it into a Thunderbolt 3 dock instead of Thunderbolt 4?

Yes, the cable is fully compatible with Thunderbolt 3 and will deliver up to 40Gbps data and 8K 60Hz video through a Thunderbolt 3 connection.

How can I confirm the cable is actually running at 40Gbps after I connect my external SSD?

Run a large-file transfer and check that read speeds approach 2.8GB/s and write speeds approach 2.1GB/s, which indicate the 40Gbps link is active.
