UGREEN CM478 USB-C Multifunction Adapter 100W HDMI 4K 3xUSB-A

The compact UGREEN CM478 USB‑C multifunction adapter converts a single USB‑C port into useful ports: an HDMI display output, a USB‑C PD input for pass‑through charging, and three USB‑A ports for peripherals. Its small housing and short cable make it handy for office, home and travel use — ideal for presentations, expanding I/O and connecting mice, flash drives or keyboards.

The adapter supports HDMI video up to 4K at 30 Hz and Power Delivery pass‑through charging up to 100 W (PD 3.0), allowing you to charge a laptop while using the adapter. One USB‑A port offers high‑speed data transfer up to 5 Gbps (USB 3.0); the others provide backwards compatibility with older USB devices.

Plug‑and‑play on most modern Windows, macOS and Linux systems for basic functions — no separate drivers are normally required. Good for users who need an easy way to add an external monitor and extra USB ports without a full dock.
