Universal USB-C Dock for Windows and Mac

The Ugreen 55766 is an 11-in-1 docking station finished in gray aluminium. It connects through a single full-function USB-C port on Lenovo, HP, Dell or MacBook laptops. Windows machines can drive three independent screens via MST while macOS mirrors the two external displays. The compact body measures 14.79 cm by 5.76 cm by 1.61 cm and weighs 175 grams.

Dual Video and High-Speed Data Ports

One HDMI 2.0 output reaches 4K at 60 Hz and one DisplayPort 1.4 output reaches 4K at 120 Hz, enabling dual-monitor workflows or 3440 x 1440 at 180 Hz on ultrawide panels. Two USB-C ports and two USB-A ports provide 10 Gbps and legacy connections respectively. A Gigabit Ethernet jack, 3.5 mm audio with 24-bit 192 kHz support and SD/TF slots rated at 104 MB/s complete the I/O set.

100 W Power Delivery with 85 W Laptop Charging

The dock accepts up to 100 W from a USB-C charger and reserves 5 W to 15 W for its own hub controller, delivering up to 85 W to the host laptop. This keeps a MacBook Pro 16 or Dell XPS 15 powered under load without throttling. Buyers whose laptops require more than 85 W or who need Thunderbolt-certified bandwidth should look elsewhere.

Questions about this item

Does the aluminum body need any thermal paste replacement or fan cleaning over time?

The dock has no fan and uses passive cooling through its aluminum chassis, so there are no moving parts to clean or thermal paste to replace.

Which port or controller hits its ceiling first when I run dual 4K displays plus an NVMe SSD at full speed all day?

The GL3590 USB 3.2 Gen2 hub controller manages the 10 Gbps USB-C ports, and the 16.2 Gbps display bandwidth with DSC compression handles the video streams; sustained NVMe transfers at 1050 MB/s stay within the USB-C 10 Gbps limit.

How hot and loud does the unit get after 12 hours of 100 W pass-through charging and dual-monitor output?

The aluminum body is rated to stay at 45 °C under 12-hour full load, and the fanless design means it runs silently.
