USB 4 Cable 1FT 40Gbps, 2 Packs, USB C to USB C 240W, 8K Video Monitor

I only use the cable at 10 - 20 Gb/s but it performs perfectly. The length of the cable and its build quality are great. It is a little stiff but I expect that considering the individual conductors of the cable must be thicker to handle the current draw for a 240W charge capacity. I have not tested the cable for charging a device.

These cables are super sturdy and reliable. I’m a photographer and my girlfriend is a graphic designer, so our portable SSDs are very important to us. They are never ejected improperly and they have always been recognized by both our Windows and Apple computers. If I have the need to, I will definitely be ordering these cables again.

I use these for replacement NVME 2.0 ssd external drives and they work great. built to last and the braided materials keep it from kinking. fast transfer and charging speed also.

This week I purchased a highly rated 1-foot USB C-C cable from Amazon and gave it a try. Within a minute, I found out why the price was so inexpensive. I needed a back-up high-speed cable to download high-resolution images from my digital camera. My current cable plugged into my slowest port is quite adequate for importing 60mb, 14-bit files, 20-30 per 5-10 seconds and when I'm on the road shooting, it can be 1000-1200 images per day so speed is critical for downloading if I was to sleep or relax after photographing all day. As I first said, I tried a less expensive cable and I was downloading a single image, waiting, then a couple of images, waiting, and.... I knew I had made a mistake and returned them. Although I purchased 3 cables for less than I paid for one of the pair I purchased, it was a waste of time and $$$. I checked into other cables on Amazon and found these and they are built more robustly. However, more importantly, in the same port, I think it may be even faster than my older cable, which was quite fast on its own accord. The extra length over my six-inch cable makes it more convenient, too, so I don't have to try to balance the card reader and hard drive over the edge of a small work surface. Save yourself the trouble and just pay the extra price for much better compatibility, better build, and faster cables that the SUMPK brand sees to be.

Fast but stiff. This might be a little stiff for some people but it does match the speed and data transfer speed.

Great price for what seem to be a great simple product. They support fast charging.

Use for charging at a fast rate for certain products like cell phone or tablets.

I bought a 2-pack of these cords. One of them stopped working on the third day. There is no visible damage to the cord. So far, the other one is still working. Buy another brand if you want a 240W USB-C cable.

Muy muy bueno

Schnelle Lieferung und hervorragende Verarbeitung. Klare Kaufempfehlung!

Prezzo non economico ma giustificato, i cavi sembrano davvero resistenti e utilizzato con un hub usb c fanno il loro dovere egregiamente. Con il vecchio cavo il segnale video hdmi dava problemi, con questo ho risolto.

Seem to work fine - very stiff cables

Good quality cables. I've only used them for charging, but I've used them for charging laptops etc with no problems. Some cheaper cables can't handle high-power devices like laptops, but these cables managed fine.
