Great quality TB3 Cable
Great item, follows spec exactly. There are very limited options for these cables, and especially for the longer cables. Typically you get these included with the docks and devices people buy, but if these get damaged they are not easy to find. I unfortunately have 2 TB3 docks and a TB3 RAID going into 2 Macs. Unfortunately my cat decided to to bite through all three so I need to replace these ASAP. These were about the only option available and fortunately work great, data transfer and power transfer flawlessly and just work exactly as expected. Hopefully they’ll start making longer versions soon so I can hide more stuff under my desk!

Works well for USB-C 4K monitor with high speed charging
I use this with a Dell U2720Q monitor with a Macbook Pro, as a USB-C cable. Works with high speed (90W) charging and 4K60. Feels nicely made, nice and flexible.

Using with a bus powered TB3 audio interface. Works great.
I’m using this with a UA Arrow, which is a bus powered TB3 professional audio interface. It works perfectly with this interface. No issues with power delivery over the cable. The cable quality seems high.

Did not work for me
This StarTech cable did not work for me.I am connecting my Dell XPS 13 laptop to Phillips Super Ultrawide monitor 499p9h. The cable supplied with the monitor works very well, but is also very short. This StarTech did not work.No image is produced on the monitor, although the monitor does wake up momentarily upon connection, but then quickly goes back to sleep.This monitor has a built-in TypeC hub, so I have other devices connected to the monitor, like mouse and keyboard. The laptop was able to connect to these devices through the monitor, although the monitor itself was blank.The original cable, what came with the monitor, is not only shorter, but also considerably thicker than this StarTech cable. Perhaps StarTech have forgotten to put some of the main wires in? 😉

Expensive but works well..
TB3 cables are stupidly expensive – we all know this. I needed a long one – it was even more expensive. But all this said, it’s well built and works well. It’s just expensive, did I mention that?

Better than generic brands.
Purchased for £19.99. At this price represents value for money. Some of these cables are pushing £70, which is absurd.Bought to replace a similarly priced generic thunderbolt cable, as it kept falling out of my UA Apollo x4 audio interface. Complained to UA, who advised me to get this brand instead. Was sceptical, but must say the StarTech fits much tighter. Have written this review because reading one like this would have helped me with my decision.With the caveat that the cable only arrived today – do hope that it doesn’t loosen with time.

Connectivity AND Power in a good quality cable
Well, I needed a longer cable to connect my Kensington Dock mounted on the rear of the monitor to my laptop. This does the job, provides full connectivity and supplies power to the laptop as well. Excellent quality and recommended.

Sirve para datos, no sirve para datos y carga simultáneamente, ¡solo recomiendo su compra si se quiere para datos¡ hay mejores cables que hacen ambas funciones

Un poco caro pero funciona para lo que lo necesitaba, cargar y transmitir la imagen desde la pantalla USB-C a mi MacBook Pro finales de 2016.

Acquistato tramite Amazon Warehouse Deals!Ed è stato proprio un affare, 2m a â¬32!Il prezzo per un cavo nuovo è fuori dal mondo. I cavi Thunderbolt 3 sono troppo cari.Questo è conforme a 40GB/s, USB C Thunderbolt 3, ideale per monitor esterni, ricarica di MacBook Pro e connessioni a eGPU.
