This is a QacQoc GN28A USB type-C Hub adapter, and it's amazing.
I got this dongle last year alone with my 2017 MacBook pro 13'. Everyone is gonna get a dongle right? I was happy with the design of the dongle, but at very beginning I was so disappointed with the performance.
It takes up two USB-C ports, providing two back, with two additional USB-A and two SD card readers. I know only one of the type-C ports support power delivery, but what I didn't know is, the same port also is the only one that supports video output. The other USB-C next to it is just a regular 5 GB/s USB 3.0 port, neither support power delivery nor video output.
Because USB type-C was a new thing to me, I thought type-c = USB3 = thunderbolt 3. At that time I didn't know type-c refers just the shape of the connector, it could be Thunderbolt 3, USB 3.1 gen2, 3.0, 2.0 or even just power cord only.
My 4k monitor doesn't provide power to MacBook so if I connect my monitor to the dongle, I have to connect the AC power to the other side of the mac. It against the purpose of buying this, because at least I can plug in video and charging cable at the same side without dongle, but I can't with this.
So I almost forgot I even have this dongle, until yesterday.
My new 2018 MacBook pro works fine with Blackmagic eGPU. The eGPU can charge my mac and doing GPU stuff with one type-c cable, in addition it provides 4 USB-A 3.1 ports. I have a USB-A SD card reader so when I need to read SD card I plugged it in the back of the eGPU, it's inconvenient but not unacceptable. However, I also want to use my Logitech mouse. The mouse has Bluetooth mode but in this mode it's very laggy. It works better with a receiver, but if I plug the receiver on the back of eGPU, it can't pick up the signal from the mouse, the cursor won't move at all.
So I took out the long-time not being used dongle to make Logitech receiver facing towards my mouse. But what about the eGPU? I don't want to plug it to the other side of the laptop since it is so close to the wall. Why not give dongle a try? I think.
And wow! It works!
I'm so amazed since I didn't expect it to be working at all. I went to system configrations.app to check the bandwidth, it did show up to 40Gb/s. Then I ran geekbench 4 Metal test to see if the eGPU could deliver the same performance through the dongle. It gave me 119977, the highest score I have ever had...Then I went to see power information, it did say 85w.
But I still couldn't believe the dongle supports thunderbolt 3 up to 40Gb/s. It is a 2016 product, with price only is half of some Belkin equivalent (even some fancy Belkin or Satechi dongles don't give you full 40Gb/s bandwidth).
And perhaps QacQoc is a really poorly advertised dongle manufacturer. The manual came with the dongle is so confusing, with nowhere mentioned if it support thunderbolt 3. The official website also didn't say anything about it, it didn't mention if it do support 85w charging. The company really need some good marketing and promo people.
So I sent them a email asking the specs, they replied with positive answer: yes it's a TB 3 ports with 40Gb/s speed and yes it support up to 87w charging. But the other type-c is just a regular USB 3.0, which I could totally understand, because it occupies just two USB port to provide four USB ports in addition to two SD reader.
I didn't expect that a dongle I bought almost 2 years ago could solve almost all the problems I had. I'm so happy with this dongle. And I think I will keep buying QacQoc and not giving premium to some brand like Belkin.
