IOGEAR Thunderbolt 3 Travel Dock GTD300 REVIEW


The Thunderbolt 3 Travel Dock is a 4-port dock that helps to expand a laptop or tablet’s ports while you are on the go. It features ultra-fast Thunderbolt 3 data rates up to 40 Gbps and can connect to single or dual 4K displays (4096 x 2160 @ 60Hz). The compact design also features a hideaway cable compartment. The dock also provides users with Gigabit Ethernet network connection. To use the Thunderbolt 3 Travel Dock, a user must have a Thunderbolt 3 enabled computer with Windows 7/8/8.1/10 or macOS 10.7+. NOTE: Many Thunderbolt 3 PCs require software and firmware updates to ensure functionality with Thunderbolt 3 adapters and docking stations.

The IOGEAR Thunderbolt 3 Travel Dock comes in a standard IOGEAR box with white and green branded colors on it. There is a nice image of the product on the face of the box and basic details of the product on the back. There are no instructions included since the dock is a plug-n-play device. That said, IOGEAR did include a warranty card with the product.


The Thunderbolt 3 Travel Dock is a worthy companion for on-the-go work assignments. It does a good job of staying in one place when on a desktop and provides much faster transfer times than my standard USB-C travel dock. I do wish it was a little bit more affordable since it does only provide one USB-A port and in a travel situation, that is usually what I need the most. While I appreciate the dual-display port option, I think that an HDMI port alone would suffice since it is a travel dock. I think users of Thunderbolt 3 compatible laptops will find this dock incredibly useful and worth the investment.
