10-in-1 USB-C Docking Station

The Belkin HC-21 docking station adds dual HDMI video, gigabit Ethernet, SD and TF card slots, USB 2.0 and USB 3.0 ports plus 85W pass-through charging through a single USB-C connection. It is built for professionals who need a compact hub to drive two external displays and wired networking from a thin-and-light laptop.

Aluminium build with fixed cable

The black aluminium enclosure weighs 0.141 kilograms and includes an integrated USB-C host cable, so there is no separate cable to lose. Two HDMI ports support a single 4K display at 30 Hz or mirrored and extended dual-monitor setups on Windows, while macOS is limited to mirror mode only. The 1000Mbps RJ45 jack provides a stable wired link when Wi-Fi is congested or unavailable.

Replaces single-port dongles and basic hubs

This unit consolidates video, data, card access, networking and charging into one device, removing the need for multiple adapters. The upgrade is worthwhile when your laptop has only one USB-C port with DisplayPort Alt Mode and you regularly connect two monitors, a wired network and peripherals simultaneously. It does not suit users whose USB-C port lacks video output or who require dual extended displays on macOS.
