NAMCIM Thunderbolt 4 Cable (6.56 ft), USB4 Cable Support 120W Fast Charging/40Gbps Data Transfer/8K Display, USB C to USB C Cable, Intel Thunderbolt Certified for Type-C MacBooks, iPad Pro,Hub,Docking

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.

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.

For charging or transmitting data at high speeds.

This is one superb USB-C cable that can keep up with the 40 Gbps transfer speed of my iMacs Thunderbolt ports.

Im not sure that this is actually thunderbolt as I wasnt able to find it on the list of thunderbolt approved devices, but it does still hit the advertised 40Gbps data transfer speeds when using a usb4 nvme enclosure, so it is at least usb4. I was able to charge at 100w, but I would expect a cable at this price point to be able to do 240w (regardless of if theres any devices that can take advantage of it yet). For current device limitations, this cable is fine, but as 240w usb-c devices start to come out, this cable wont be able to do the full 240w, while others in this price point (supposedly) will.

This cable seems to be very well made with good stress relief and flexibility at the connectors. I swapped it out with an Apple USB-C cable and had comparable transfer speeds.

Until recently the longest Thunderbolt cable I could find at a reasonable price was 3-feet long. This one is significantly longer and doesn’t seem to have any significant lag in data transfer speeds.

The cable is very well made. Looking at it, feeling it in hand, all gives you a confidence that this is a high quality product. It clearly marks on the connector heads that this is a Thunderbolt 4 cable. I like this feature a lot. I have many USB-C cables through years. I would not know which one is a Thunderbolt 4 and which one is not. Having it clearly labeled helps. The cable works great.

Cable has a short. Have to move cable in a certain position to get proper connection.

This is a good Thunderbolt cable that works as intended. I was able to connect my monitor (via monitor KVM switch) to my laptop and all the things attached to the KVM worked. I was able to get the full monitor resolution at its top-rated refresh rate.
