Kramer KDOCK-1 USB-C Hub Adapter

The Kramer KDOCK-1 is a compact USB-C hub built for a single-cable laptop connection. It takes in one USB-C signal and breaks it out to an HDMI display output, a USB 2.0/3.0 Type-A port, and a USB-C charging pass-through, so a MacBook or other USB-C notebook can drive an external display and keep its own ports free at a desk or huddle room.

The HDMI output carries up to 3840x2160 at 30 Hz with HDCP 1.4 pass-through, and the built-in 16 cm USB-C cable keeps the hub tethered to the laptop rather than lost in a bag. It draws power over the same USB-C connection, so no separate power adapter ships with it.
