Portable USB-C dock for laptops

This compact StarTech.com dock adds 4K HDMI video, an SD and microSD card reader, one USB-A 5Gbps port and a USB-C data port to a single USB-C connection. It suits mobile professionals who need a lightweight adapter for presentations or quick peripheral access.

Retractable cable and 100W pass-through

The built-in retractable USB-C host connector plugs directly into a MacBook Pro or Air without a separate cable. The USB-C PD port accepts up to 100W input, reserving 8W for the dock and passing up to 92W to the laptop, so charging continues while peripherals are connected.

Check your host port capabilities

The HDMI output follows HDMI 1.4, limiting 4K resolution to 30Hz. The USB-C host port must support DisplayPort Alternate Mode for video and Power Delivery for charging; a USB-C port that carries only data will not drive the display or accept pass-through power.
