[USB-IF Certified] Cable Matters 80Gbps USB 4 Cable - 3.9ft, Supports Up to [8K@120Hz / 4K@480Hz Video, 240W Charging, 80Gbps Data Transfer] USB4 Cable, Black, Compatible with Thunderbolt 5/4, MacBook

Picked this up for high-speed data transfer and it delivers. Full 80Gbps throughput, no dropouts, and the USB-IF certification gives you confidence it’s not a cheap knockoff. Build quality feels solid. If you need a USB 4 cable that actually performs to spec, this is it.

I have purchased several cables from Amazon, and I think this is one of the best so far. Very well-made, thick, durable, quality finish, very clear indication of speed rating, charges my iPhone 17 Pro extremely quickly with an Apple charger, connects perfectly to all USB-C ports, is just the right length for use in my SmallRig iPhone 17 Pro phone cage system. Would strongly recommend.

Fast charging, fast data transfer, pretty much everything as advertised. Does this meet all the check boxes as advertised, it has a very premium quality feel when you first take it out of the package you can tell her right away that it's not flimsy and the build quality is good. I know there's some complaints, but I would rather have a nice heavy duty cord than a flimsy cord without the shielding or capabilities. It's a quality product and the price is well worth it. I currently have four of these and I'm happy with every single one.

Sturdy cable, works for my monitors directly connected to the laptop

Works great/fast. Only detraction is cable is very stiff. Could be more flexible

Without questions the most stable and high quality USB4/TB3/TB4 cable you can get for the $. Essentially you're saving money because they didn't have to pay money to get the cable certified. That means you're at the mercy of the company who makes it to ensure the cable meets expectations / requirements. Cable Matters is an established brand. I have their intel certified TB cables, and I have this one. The difference is I payed 17.99 for this one, and 39.99 for the certified one. This one is a almost 5 ft. I use it to connect an eGPU to a Legion Go. I use the Legion Go's built in screen too, and the cable has no problem sending large amounts of data both ways simultaneously. This is probably the easiest product to recommend. You will not find anything even close to this level of quality . One drawbac. It's thick. It's stiff. You'll be best off using it for desktop hookups, vs having it hanging off the device while you hold it. It'll work either way. It's just a bit more pressure having hang off the Legion Go when you're holding it. I manage fine but others may find it annoying. Small price to pay for rock solid durability and stability. Look up the "OWC Cling-On" if you're paranoid about the usb port fittings getting loose or bending over time. I use the cling-on for my eGPU port, and I'm just extra careful pluging the other side into the Legion Go's USB4 port. works out well. peace of mind.

I am sure this is a great item. I ordered it by mistake and had to return it. I found out later the correct item I needed.

I use this cable only for charging my iPhone and tablet. But what a difference in speed from any other cable. Great length

Real certified USB-IF cable unlike most fake brands. Top quality and super price. Best Thunderbolt alternative for amazing quality.

Excellent cable but had to return due to the length. For dual monitors setup you need 2m

Bardzo sztywny przewod, działa świetnie z egpu.

Worked as described, seems to be good quality

Cable is a bit stiff but works well.
