IOGEAR Quantum Thunderbolt 3 Docking Station Pro 85 REVIEW


The Quantum Thunderbolt 3 Docking Station Pro 85 gives users the opportunity to connect all essential devices through one centralized hub — so to speak — with super speed. The dock connects to your computer — in my case a 2016 MacBook Pro with Touch Bar (13-inch) — using Thunderbolt 3, which can provide up to 40 GB/s of data transfer speed. There are several additional ports on the dock, which I will discuss in just a moment, but perhaps the most intriguing feature of the docking station is that it provides up to 85W pass-through power delivery. This is enough to power any MacBook model except the 15-inch MacBook Pro with Touch Bar, which needs 87W. That said, I’ve found recently that some devices that shouldn’t be able to charge the 15-inch MBP do in fact charge its battery. I’ve yet to solve that mystery, but with the Quantum Thunderbolt 3 Docking Station Pro 85 providing 85W of power to connected devices, I believe it can handle most anything you throw at it.

As you will see by looking at this chart, both docking stations have the same port availability and the only real difference in the two is the amount of power delivery the devices provide.

User Experience

The GTD735 docking station arrives in a bright IOGEAR branded box. There is quite a bit of product information on the box including a high-quality image of the product itself. IOGEAR includes an AC adapter, Thunderbolt 3 cable, warranty card, and quick start guide along with the docking station. To get started, you will want to select the place for your dock to live. It needs to be close to a power outlet. You will want to plug it into power first and then plug in any devices you want to have connected to your computer.


This is a really nice option for a workstation. As lightweight as it is, I would love to see IOGEAR come out with a travel pouch for it so that people could travel easier with it. The power brick is quite large (it’s actually almost as large as the docking station itself), but I think it would still be a helpful agent on the road. IOGEAR continues to meet my expectations for high-quality products and I’m looking forward to seeing the next generation of products they release.
