Why choose it

One compact hub eliminates the need for multiple dongles. The 4K HDMI output brings crisp visuals to presentations and extended desktops, while three USB-A ports handle keyboards, mice, and external drives. The 100W PD port keeps your laptop charged under load, and the dual card reader speeds up photo and video workflows. Its sturdy aluminum shell resists scratches and looks professional.

Ideal use cases

• Office workers connecting a laptop to a monitor, keyboard, mouse, and USB headset
• Photographers and videographers importing from SD and microSD cards simultaneously
• Remote workers needing a single-cable docking solution for home and travel
• Students using an iPad Pro with external storage and HDMI display
• IT professionals testing multiple USB devices on the go

Good to know

The integrated 15 cm cable is short enough to avoid clutter but long enough for flexible placement. The hub is bus-powered and does not require an external power supply; however, for charging your laptop via the PD port, you need a USB-C charger (not included). The HDMI port supports up to 4K@30Hz, which is ideal for productivity but not for high-refresh gaming. The card slots accept standard SD and microSD cards up to UHS-I speed. No drivers are needed on any supported OS.
