Review on 🌍 Enhance Your Travel Setup with IOGEAR Thunderbolt 3 Dual 4K@60Hz Travel Dock, GTD300 by Chris Litton

This device works with HDMI and Display Port at the same time, but your MacBook needs to be powered. I'm using two 27" monitors on a 2019 MacBook, but I've noticed that when I unplug the MacBook, the monitors turn off. So it must be the power consumption of the Thunderbolt 3 port when trying to run a multi-monitor configuration.
