  • Universal, compact cable to use everywhere.
Size: 1.5ft Style: 40Gbps | Black
I'm glad to have this one. Added couple USB-A adapters to it and use everywhere. Suitable for Super Charging of Samsung Tab 7S: provides ~28w. It's flexible so it's possible to compact one and place into "pocket" easily.

  • Works good. A little loose.
Size: 6ft Style: 40Gbps | Black
If you want a 40 Gb/s 6ft cable, pickings are slim and this is one. It is handling 40 Gb/s fine for my Dell XPS 15 7590 and dual DP docking station hooked to two 4k displays. It is a slight bit lose in the connector for the Dell XPS 15. For the Lenovo T580 and T590 machines I have tried it on, it is really lose and connectivity becomes a bit of a problem. Then again Lenovo has really dropped the ball in multiple ways when it comes to TB3. A couple examples are the T590 only has 2 of the 4 lanes hooked up, the T580 only seems to have 2 lanes hooked up in their multi-port and USB 3 for the other USB-C style port (generally used for charging), so can't do dual 4k displays through one cable. Also the multi-port on the T580 and T590 is super lose. Even when I get the cable positioned so the video isn't cutting out, I am having a lot of problems with the keyboard and mouse freezing up for a couple of seconds at a time once every few seconds, so have to connect the keyboard and mouse directory to the Lenvovo laptops in order to have a usable experience. Plus the Lenovo's won't boot with the docking station plugging in, so have to plug it in after the laptop boots. The Dell XPS 15 7590 on the other hand is smooth sailing on all fronts listed here, so it is not an issue with the cable so much I think as Lenovo dropped the ball on their laptops. While my docking station is rated for 85W over TB3, my Dell XPS 15 7590 reports 65W max delivery, which is less than the 130W is is rated to carry over its dedicated charge port. Then again for most laptops most of the time 65W is fine. I have managed to get it to draw some from the battery while maxing out the TB3 link, but the laptop was also maxing out its temperature, which is not a good way to treat a laptop if you want it to last a while. I do have liquid cooled desk side computers, so my plan is to keep heavy lifting to those boxes anyways, so 65W is fine. The end verdict is with the right laptop, this cable is plenty good for the job. I mainly knock off a star because it is a little on the loose fitting side to the point of causing problems where other USB-C style connectors work well enough. It seems to only be the case of where the connector on the computer / device is already a bit on the lose side with other connectors does this one push it over the edge to be problematic. In places where it is normally a tight fit, the extra looseness in stationary use seems to not be an issue. My goal with this cable is to hook up a laptop that is off to the side to a docking station that is too far away for a passive TB3 to reach. ... show more

  • It works, but the TB3 specification is kinda a mess
Size: 6ft Style: 40Gbps | Black
I bought this to be used for my eGPU (which is a Razer Core X in tandem with my Razer Blade Stealth i7-8550u) just in case I needed a much longer TB3 cable, and it works for that use case. I don't have the know-how in doing performance benchmarks in finding a performance loss if you'll use a much longer cable like this one than the included cable in the Razer Core X (I'm saying this because it's commonly asked). But after testing it out on games I didn't really notice any major performance loss. But I'll say that using the included shorter cable feels more responsive overall, but I think it's just me. The cable quality is good, the cable is sturdy enough to handle a daily in and out bag throw, but I'll strongly advise to still take care of this, why? Because this is too expensive for a cable. Now regarding the TB3 specification, again in the case of using it for an eGPU it does work but if you're looking at this and (NOT JUST) using it for TB3 devices but a "one USB-C cable to rule them all", this is not it. This is relevant because USB-C should simplify the cable & ports specification problem we're having, but with the TB3 specification this isn't helping. This cable is what they specify as an active TB3 cable which means you can only use this at its actual TB3 specs when IT'S connected ON both ends to a TB3 enabled device. This means if you want to use this as a native DP (Display Port) cable for your monitor, this cable will not work. Another thing is if you try to use this as a normal USB cable, it will only WORK AT THE SPEED of A USB 2 (480 Mbit/s) NOT the speed of USB 3.0 (5 Gbps) or 3.1 (10 Gbps). But obviously if you don't plan on using this cable for those cases, then this should do you fine. And lastly, the thing that I don't like the most is the price, these things are just too expensive. So just make the most out of this if you decided to go the TB3 ecosystem. Side note: The TB4 specifications is on the works as of writing, so if you don't really need this but just wanna try out TB3, I would advise to wait until the end of this year or until next year for the TB4 to make its appearance. The TB4 specs seem to address the problems of TB3 standards and also that may hopefully drop the prices of TB3 accessories and cables. ... show more
