NAMCIM Thunderbolt 4 Cable, Thunderbolt Certified, 1.0 Meter (3.28 ft.), 40 Gb/s Data Transfer, 120W Power Charging, Compatible with Thunderbolt 4, Thunderbolt 3, USB-C, and USB4 Devices, Black

A very well constructed Thunderbolt 4/ USB 4 cable with the specifications that you expect from such a cable. At 6.6 feet, it has the length for a number of use cases in which a little added length is desirable. What clearly differentiates this cable from others in the same class is its price. This is offered at a price that is far superior than what could find with other brands. And frankly, I have not been able to find any difference between the higher priced cables and this one. Certainly worth considering if you are in the market for Thunderbolt 4 cable. Works great with high speed monitors, external SSDs and as a power cable.

I compared four USB4 40 Gbps cables.

I tested this cable with a Caldigit Thunderbolt Station 3 Plus dock. It connected a new Framework laptop (12gen intel i5 model) running Ubuntu 22.04, as well as a 15.4 Macbook Pro (2019) running Monterey. I did not test for data transfer speeds, but video, USB, sound, charging and network connectivity all functioned through the cable. Both computers went into an IOGear 4Port KVM switch out to an LG 32 monitor running at 3840x2160. It is a more complicated setup than most, but the cable did not have any issues.

I have a Thunderbolt 4 cable going to an OWC Thunderbolt dock at work. I replaced that cable with this one and everything performed the same.

This is the high-end Thunderbolt cable I needed for my Mac because it supports 40Gbps file transfers which most regular USB-C cables do not. It also supports Power Delivery 3.0 for 100W of charging power although the title says 120W.

This is a good quality cable and its ideal size for imac to portable HD applications in my opinion, 3feet is too short and 6 feet is too long...

Namcim Thunderbolt 4 Cable

This is a well-made, high quality Thunderbolt 4 / USB 4 cable. The cable is thick and covered in braid. It has markings on the connectors so you know what cable it is. When cables are unmarked, its hard to tell if theyre USB 3 or Thunderbolt 4 / USB 4.

If youre in the market for a USB C to USBC cable, you are likely to be aware of the standards mess that allows cable manufacturers to sell some cables for charging only and others for data and others for both, but at all manner of charging rates. This is all thanks to the USB Implementers Forum for a botched implementation.
