Design and features

The Quantum 3 is a beautiful piece of equipment that looks at home with current computers of the aluminum variety and provides all kinds of connectivity to your USB-C computer at your workstation. The main body is aluminum with plastic used for the inset back connector panel and the end panels which sport a cool repeating triangular relief pattern.

As you can see in the next photo, there are also connections for gigabit ethernet, USB 3.0, microphone, headphones, USB-C, displayport and power.

On the front of the unit there is a pair of connectors, one for USB-C and one for USB 3.0.


Connect to Quantum 3 to its power supply and then the included USB-C cable to your computer. It’s important to note that the first one with the [    ] around the port has a higher throughput and 85 power supply for connecting to your computer, supporting the other functions through the hub and keeping your computer charged without a separate power cable.

All that’s left is connecting everything else you plan to use. I have an HP Envy ultrawide monitor that I selected specifically because it had USB-C input. What I found in initial use is that some of the other connections through the monitor like standard USB 3.0 accessories, required me to add another cable to my mac which is what I was trying to avoid in the first place.

With the Quantum 3, I connected a DisplayPort cable to the monitor along with a USB 3.0 cable and that’s it. The office I work in is all wifi, so I haven’t had to try the gigabit ethernet yet. Maybe in the new office starting next week.


It’s really quite amazing how seamless a product can be when it does exactly what it’s supposed to. It’s not like I forget that it’s there, but at the same time, I don’t have to monkey with it. With the connections described above, I’m able to set my Mac down, connect a single USB-C cable and everything just works and my Mac is charging. The headphone amp that’s connected to the monitor with USB works perfectly. The monitor’s built-in pop-up camera works perfectly (previously required an extra cable to the mac). I can go on, but you get the picture.

I’ve got the Quantum 3 tucked into a pocket of my desk riser where I have access to the front two ports should I need them and everything else is out of the way.

What I like

  • Simple set-up
  • It just works
  • Single connection to the computer (including charging!)

What needs to be improved

  • The cost is pretty steep (but less so when you factor in the cost of buying a second Mac power adapter)

Final thoughts

The Quantum 3 is a docking station that does exactly what it’s intended to do. It’s not inexpensive but is incredibly well made and will likely outlast a couple of laptops. If the idea of a single connection to your computer gets you excited, this is a great solution. I’m at my desk a lot during the day, but it is generally in fits and starts and that means a lot of plugging and unplugging. The Quantum 3 solved that with style and now the power adapter that came with my Mac can stay in my backpack.
