This Monoprice Thunderbolt™ 3 Dual HDMI® Mini Dock provides the connectivity of a full sized Thunderbolt 3 dock, but in a compact, portable design. This mini dock lets you add two 4K@60Hz HDMI displays to extend the desktop or mirror the display of your Windows® or Mac® computer, using a single USB-C™ Thunderbolt 3 port. The USB 3.0 port allows you to add a SuperSpeed external device, such as a portable hard drive, flash drive, etc., at speeds up to 5Gbps, while the USB 2.0 port extends your connectivity options for an additional High Speed external device, such as a keyboard or mouse. A Gigabit Ethernet port allows you to stay connected at speeds up to 1000Mbps for a secure, stable, wired connection to your network. It draws all the power it needs from the USB Type-C™ Thunderbolt 3 connection, so no external power adapter is required. Portability is further enhanced by the integrated USB-C Thunderbolt 3 cable, so no additional cables need to be stuffed into your laptop bag.
