Docking station Baseus UltraJoy Series 5‑Port USB-C to HDMI 4K@30Hz + 4× USB 3.0, Space Grey

The Baseus UltraJoy Series 5‑Port USB-C docking station is a compact connectivity hub that expands a USB‑C port into a single HDMI video output and four USB 3.0 Type‑A ports. Housed in a Space Grey enclosure, the dock provides a simple way to connect an external display at up to 4K@30Hz while attaching keyboards, mice, flash drives and other USB accessories at USB 3.0 transfer speeds. It is designed for laptops and devices with a USB‑C port that support video output or host mode, offering a portable solution to improve workstation flexibility without adding bulk.

Advantages

The HDMI output supports high-resolution display up to 4K@30Hz for presentations, video playback or extended desktop use, while the four USB 3.0 Type‑A ports deliver faster data transfer compared with USB 2.0 and compatibility with a wide range of legacy USB peripherals. The Space Grey aluminium-look housing provides a compact, travel-friendly footprint and straightforward plug-and-play operation with no additional drivers required for most modern operating systems.

How to use

Connect the dock to a compatible device using the built‑in USB‑C cable or included connector, then attach an HDMI cable from the dock to an external monitor or projector. Plug USB peripherals into the available USB 3.0 Type‑A ports. Most operating systems will recognize connected devices automatically; adjust display settings from the host device to configure resolution, mirroring or extended desktop mode as needed. Ensure the host device supports USB‑C video output (DisplayPort Alternate Mode) for HDMI functionality.

Usage recommendations

Use good‑quality HDMI and USB cables for reliable signal transmission. For best display performance at 4K@30Hz, confirm the host device’s USB‑C port supports video output and set the external display resolution accordingly. Avoid loading all USB ports with high‑power devices simultaneously if the host cannot supply sufficient power through the USB‑C port.
