Compact Thunderbolt 3 dock

This compact docking station adds dual 4K HDMI outputs, one USB 3.0 port, one USB 2.0 port and a Gigabit Ethernet connection through a single Thunderbolt 3 USB-C port. It supports extended or mirrored displays at up to 4096x2160 at 60Hz. The bus-powered design requires no external power adapter, making it a portable expansion option for notebook users. Compatible with Windows 10 and Mac OS 10.13 or 10.14.

Build integration

The dock connects directly to an available Thunderbolt 3 port on the host notebook and draws all power from that link, freeing the user from carrying a separate power supply. Two HDMI cables, up to two USB peripherals and a wired network cable can be attached simultaneously. Because it is bus-powered, the total power available for downstream USB devices is limited by the host port's own output capability.

Display and connectivity headroom

Dual monitors at 4096x2160 60Hz or 3840x2160 60Hz are supported, giving ample headroom for typical productivity resolutions. The single USB 3.0 and USB 2.0 ports handle keyboards, mice or storage drives, but builders needing more downstream ports or higher-bandwidth USB 3.1 Gen 2 connections will need an additional hub. The Gigabit Ethernet port provides a stable wired link where Wi-Fi is unreliable.
