Cable Matters 40Gbps USB 4 Cable - 6.6ft, Supports Up to [8K@60Hz / 4K@240Hz Video, 240W Charging, 40Gbps Data Transfer] USB4 Cable, Black, Compatible with Thunderbolt 4, MacBook, XPS, Surface Pro

The best cable I've ever owned. My only complaint is that maybe it's a little too durable and hard to flex

These Cable Matters 40Gbps USB4 cables have dramatically improved performance—more than doubling the speed of my USB to M.2 converters. They’re very stiff and feel like high-quality, well-built cables. Easy to use, reliable, and absolutely worth the upgrade. Highly recommend!

For my Windows desktop pc, I recently purchased a USB-C hub that has a USB-C port (hard to find a so-called USB-C hub that actually has a USB-C port). To connect with my iPhone, I had already tried a USB-C to USB-C cable that I already had, but I found that the connection didn't always happen. So I decided that I needed to get a high-quality, fast, and short USB-C to USB-C cable to hook up my iPhone to the hub.I looked around and found the Cable Matters 1 ft. USB 4 cable and this is exactly what I needed. I tested the cable with a 4 GB video file, and it was about a second faster copying the file than a high-speed cable I bought recently from a competitor.I also like the fact that the cable is nice and stiff, which makes it lie flat on top of the desktop, either when not in use or connected to the iPhone.A highly recommended cable if you want speed and reliability.

Forget about paying $50+ for a 2-m Thunderbolt 4 cable. This cable is recognized as TB4 and USB4 and transfer over it to my TB4 hub worked perfectly for a fraction of the cost of usual TB4 cables. Charging of both a MacBook Pro and an iPhone 15 worked fine at full charging brick power. The only downside to this cable is perhaps that it's only available in smooth black plastic and that it is a bit thicker than USB3 or USB2 cables. But if you need TB4/3 or USB4 cable that can also charge, this is the one cable to rule them all. And at this price you might as well just get this for everything.

I was surprised by just how thick this cable is - almost as thick as an HDMI cable - but it's great for connecting my phone to my PC for faster transfer speeds

I needed a TB cable shorter than I had and this fit the bill. No issue with speeds. Feels plenty rugged.

Pro:The cable is flawless in video transfer from my USB 3.2 port to my monitor.Excellent for USB 4.0 devices.Cons:Not all USB 3.2 and 3.1 devices can utilize this cable due to inadequate power supply to the USB device. I was unable to power any of my USB M.2 and 2.5" SSD enclosures using this cable to my 3.2 Gen 2 USB ports and 3.1 ports.

Tested results showed this to be one of the very best cables you can buy. And it lived up to the transfer speed and power transfer charging. Will buy more as I need them in the future.
