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

This cable is HEFTY. The wire itself is thick, thicker than any USB C that I own. The jacket on it feels durable, and seems to be a mix of fabric and rubber. It does not feel like it will easily snag. The ends are heavy duty, and certainly bigger than any the ends of any cables I own. As this is my first USB 4 cable, this may be how they are. Right away after plugging into my phone, table, and laptop, each device charges at full power. I was able to test up to 100w, as this is the highest drain device I have. I was alson able to offload pictures from my phone faster than ever. While I do not yet own a USB 4 device, I have every confidence that this cable will perform just as well with one. I also feel like it will last for a while, until I end up getting one. Highly recommend for todays USB C devices, and tomorrows USB 4s.

This is just a great cable. Yeah, its a bit expensive, but youre getting what you pay for here, and then some. The data throughput meets expectations, as does the charging current capabilities. Theres not a whole lot more that I can say about a product that is well constructed and meets the advertised specifications, other than to say that I am wholly satisfied and would purchase again in an instant. Its easy to write a tome for a product that fails to meet your expectations or advertised specifications, but not so with this cable. Its just fantastic. Highly recommended!

I needed a new high speed thunderbolt cable for my dock and this knocks it out of the park. It has the transfer speeds you want while being a very durable cable that I know isnt going to fray or become damaged no matter what I do to it.

This cable looks and feels well made and durable. Using it with a Mac and it works as expected. A little on the pricey side but the quality justifies it. Only minor downside is that its a little stiff but thats a fair tradeoff for durability. I expect it to last a long time.

Very well made, short Thunderbolt 4 Cable. This is pretty much the fastest cable available right now. Faster the USB C and faster than USB 3.2 gen 2x2.

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

:: Initial experience ::

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.

Extremely fast charging. I was pleasantly surprised at how fast this charged.
