NAMCIM Thunderbolt 4 Cable (3.94ft), 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

Excellent build quality. No issues to speak of. Data speeds seem to be up to par. I haven’t had any issues, although I haven’t ran an official speed test.

I didnt have a specific use in mind for the NAMCIM Thunderbolt 4 cable when I ordered it beyond wanting redundancy for the cable Im currently using to connect an Intel NUC -- which is my daily-driver PC for basic productivity -- to an M32U monitor KVM. The quality of materials and construction appear good superficially but whats inside matters most, and that I cant see without rendering the cable useless, so Ill have to let performance be my guide.

This cable is a perfect replacement for my old thunderbolt cable. I had no issues with the cable and connectivity was perfect.

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.

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.

So far Ive had no issues with this cable.

This cable is braided and pretty flexible. It feels great and so far has been working great. I use it for my external GPU and have had no problems so far.

The NAMCIM Thunderbolt 4 Cable is a quality cable with excellent quality. The cable meets or exceeds all the specifications listed and has a quality braided design. The cable is a 1M cable and does work as a Thunderbolt 4 cable and can deliver loads of power for charging purposes. Quality cable at a reasonable price, highly recommended.

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.

The quality of this cable is apparent from the minute you take it out of the box. It is clearly constructed far better than the $5-$10 ones that you see everywhere. It feels strong, substantial, and durable.
