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

I recently purchased the NAMCIM Thunderbolt 4 Cable for use with my Focusrite audio adapter, and I couldnt be more pleased with my purchase. This cable is a high-quality product that delivers on its promises.

I needed a longer cable for my docking station and this NAMCIM Thunderbolt 4 certified cable was exactly what I needed. Excellent cable.

I’ve only used it so far to charge my MacBook Pro and it works well. It will be part ov my travel bag when I’m on the road for when I do data transfer and their not wireless.

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.

So far Ive had no issues with this cable.

It wasnt all that long ago that USB cables maxed out at 480mbps for data and perhaps 12W if you were lucky (but more often 5-8W...) in power transmission. That should be good enough to be all that one would ever need right?

I tried this with an iPad Pro M1 and my LG Ultrafine 5K which uses a thunderbolt connection and it worked well. There was no discernible difference vs the thunderbolt cable that LG provided with the monitor. I also connected to my M1 Mac Mini and under the system details it reported up to 40Gbps which is the theoretical throughput for Thunderbolt 4. So overall, it does what it is supposed to do. But to be clear, I dont have more precise measuring tools to do a super detailed analysis. But I have not encountered any problems.

I purchased this as I needed a longer cable for my USB-C docking station and HP laptop. The cable is braided and has aluminum ends so it doesn’t feel cheap. I plugged it in and it worked with my laptop and docking station perfectly. The laptop continued to charge, my wired ethernet connected, and my two 4K displays were crystal clear.

We ordered this for our portable screen. I wanted a shorter cord since the one it came with was 6ft and always in the way.

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.
