USB C Extension Cable

Looks nice and does the job. I hooked it up to a HDMI/USB-C/USB-A hub. HDMI and USB-C worked fine, but my USB-A devices didn't (they're USB 2.0, and that's important later). I fiddled around with it for a bit when I noticed a little white label on the female end of the cable stating that USB 2.0 only works on one side, and if it doesn't work flip the cable. I did, and it worked! Nice that they added that note. If you've got any USB 2.0 devices on the other side of this cable, flip the connection if they don't work.

Same as Faracent USB Type C Extension Cable. Bought this to be a USB 3.1 cable as described, tag on cable says "USB 2.0 is only supported on one side. If it doesn't work, please reverse it." Returning this and purchasing a different cable. Looks and feels nice, just need the functionality as listed in the product description.

The extension cable I received was defective. I contacted customer support and they immediately offered to refund or replace my purchase.

I have a Chromebook Pixel with a USB-C hub that I use to connect everything: keyboard, mouse, HDMI video, AND even power delivery to the laptop itself. I used this 3' cable to extend my Chromebook Pixel's connection to that hub, and it all works perfectly - even the power delivery!If you have any problems, flip one of the ends over; for some reason, which way it's oriented can make a difference for older USB2 peripherals attached. But the cable comes clearly marked with a sticker letting you know about this, so I'm not going to dock a star for it; not a big deal for me.

I will start by saying there is definitely something wrong with the construction of the cable. This is not a knock on the build quality which seems fine. Without cutting the cable in half; its impossible to tell whether or not this cable is compliant with proper Superspeed+ USB-C specs. My guess is it is not.What this cable does:- Pass USB 3.1 Gen. 1 or lower signals properly- Supply USB-PD charging at up to 100W correctly; 5A @ 20V. I even tested this with benchtop power supply and USB-C breakout board. No issues with resistance.- Pass displayport video at 4K 30Hz 8-bit or lower bandwidth video with audio.What this cable does NOT do:- Pass Thunderbolt 3 signals at any speed 40Gbps or 20Gbps**- Pass USB 3.1 Gen. 2 signals reliably. Any external interference or movement of the cable causes disruption of data transmission.- 4K 60Hz HDR; the signal either cuts out constantly or results in significant visual artifacts.Thunderbolt 3 analysis:40Gbps is automatically not possible as passive cables over 0.5m do not work. 20Gbps should be possible up to 3m but 2m is the typical limit for most cable constructions. This means this cable cannot be used to extend another thunderbolt cable regardless of length. If you are buying this cable for that purpose you can forgot it. Just buy a proper length Thunderbolt cable.This cable would only be useful on Thunderbolt devices with a rare male connector; or more commonly with a short non detachable pigtail. I used a gender changer plug to minimize distance, interference, and signal quality issues when connecting this cable between Thunderbolt devices for testing.= Tested: Macbook Pro 13in 2018 and Thunderbolt display. No video. No working ports on display.* Reference: Generic 1m Superspeed+ USB-C cable. No issues.= Tested: HP Spectre x360 13in 2017 and eGPU (Aorus Gaming Box 2070). Tries to make connection. Disconnects immediately.* Reference: Generic 1m Superspeed+ USB-C cable. No issues. Connects properly at 20Gbps. CUDA-z confirms bandwidth at 20Gbps speed.This would probably work on Thunderbolt devices that have USB 3 fallback mode (such as certain hubs and docking stations); but it won't work as Thunderbolt.Further testing:- Cut the cable to see if it actually contains miniature coax or my suspicion either STP or faux mini coax; i.e. wire with thicker insulation and a foil wrap.- I may experiment with my scope to see if its fast enough to create a proper eye diagram.

If you are using this cable as an extension for connecting a phone or for HD or lower-resolution video it will probably work fine. Their customer support is good if there are issues. I ended up trying two 6ft versions and one 3.3ft version of this cable. The 3.3ft cable mostly worked. It had frequent sound pops and pauses and occasional image or connection issues. The 6ft cables never worked in my application. I am not sure why just a few feet of USB-C cable makes such a big difference, but it does. I still haven't found a 6ft cable that works for 4k @ 60hz.I am connecting and charging a Surface Book 2 laptop through a USB-C hub connected to a 4K TV/monitor. I have tried 4 different hubs, 8 USB-C extension cables, 3 USB-C to USB-C cables, 3 USB-C to HDMI cables, and 3 HDMI cables. I have tested each exhaustively to figure out what does and doesn’t work.I am going to include what I finally found did work to hopefully save you the weeks of testing, frustration, and returns that I went through. If you are looking for a way to have one clean 3ft cable (so that the hub can be behind desk) that connects to the USB-C port on your Surface Book 2 and provides charging (95 to 100w) at same or better rate than the original charger, and connects to a 4k display at 60hz, and does not cause image or sound distortions, and allows connecting other USB peripherals to the hub, here is what works (links below):- Anker Powerline II USB-C to USB-C 3.1 Gen 2 3ft - This is the KEY PIECE! I fought through so many cables that were infuriatingly problematic and inconsistent. The Anker Powerline II worked perfectly as soon as I plugged it in and has continued to do so every time. I REALLY wish I had just found it first! It would have saved me hours and hours of frustration! If you can have the hub right next to your laptop and then a bunch of cables running out from there, then this cable is not necessary, but I needed a clean look with one cable from the laptop and then all the mess behind the monitor and desk.- WBPINE USB C Hub HDMI 5-in-1 Multiport Adapter or Koopman Dex Station USB Type C 5-in-1 Hub - These appear to be the same product and manufacturer. I like the black case and green power light of the WBPINE. Koopman offers a better warranty. Both worked the same. One of the great things about these hubs—besides the rarity of supporting 4k at 60hz and 100w power—is that the 6in cable to connect to the laptop is removable. That makes it both more durable and possible to replace the short cable with a longer one rather than having to use as USB-C extension (male-to-female) cable which I found to be more problematic and harder to find with the right specs.- Wacom 100w Power Adapter with 6ft “Mickey Mouse” AC Power Cord – This is expensive for just a power adapter. At the time, it was the only good option I could find to support 100w. Hopefully more 100w power adapters will come available at lower cost.- High Speed HDMI Cable - I have tested several. They have all worked. I could not see any difference between 4ft and 6ft, but 4ft fit my application better. Just make sure it is rated for high speed. Don’t spend more than $10.- TCL 55S423 55in TV - (From Costco) Great price. Supports Chroma 4:4:4. Has ports coming off the side rather than back. 55in is as big as I would want to go for comfortable monitor. The TCL 55S405 is similar, but I think it has the ports coming off the back which means it has to mount farther from the wall.- As a side note, the Vivo Mount-VW03G is a great mount for a 55in screen that you need to be height-adjustable and rotatable and the Vivo Desk-V111VT makes a great rolling height-adjustable standing desk.Now that I finally have the hub and cables figured out, I am loving my setup!!Links:Anker Powerline II: https://www.amazon.com/gp/product/B072JYDQ7NWBPINE Hub: https://www.amazon.com/gp/product/B07JYR7HDWKoopman Hub: https://www.amazon.com/gp/product/B07M5DMYKYWacom Power Adapter: https://www.amazon.com/gp/product/B074HDZ3QPMickey Mouse Power Cord: https://www.amazon.com/gp/product/B002V9U7WYVivo Adjustable Mount: https://www.amazon.com/dp/B0155N478MVivo Rolling Adjustable Desk: https://www.amazon.com/dp/B07GGBHQQVNote: I didn’t go with the Surface Dock because of short non-removable/extendable proprietary cable and less power delivery. I wish Microsoft would fix both of those things and offer a simple option that didn’t involve figuring out all the separate pieces above.

This is a well-built and sturdy cable. For legacy devices - like a USB 2.0 ANT+ dongle - orientation matters (if it doesn't work, flip the cable around). I haven't tested it for data transfer speed, but with that caveat, I highly recommend this product.
