UGREEN 15978 Revodok Pro 313 13-in-1 USB-C Hub Triple Display Docking Station #CM681

Key Features & Overview

• Model / SKU: 15978 / CM681 / Revodok Pro 313 

• Dock Type: USB-C (non-Thunderbolt) docking station / hub with multiple ports and triple display support 

• Display Output / Multi-Monitor Support:
   • 1 × DisplayPort (DP 1.4)
   • 2 × HDMI (HDMI 2.0)
   • Supports triple 4K displays (i.e. up to 4K@60 Hz) under MST mode 
   • For some display combinations, one of the outputs might be limited (e.g. one at 30 Hz) – reviews indicate that not all three ports can deliver 4K@60 Hz simultaneously in all host/device setups. 

• Power Delivery (PD):
   • Up to 100 W input (i.e. to power or charge a host device) 
   • Of that, ~85 W is pass-through to the host, with the remainder reserved for the hub/internal use/peripherals (≈15 W) (as observed in reviews)

   • 1 × RJ45 Gigabit Ethernet port (1,000 Mbps)

• Other Connectivity / Ports:
   • SD card slot + microSD (TF) slot
   • 3.5 mm audio (combo headphone/microphone) jack

• Transfer Speeds:
   • USB-C / USB-A “10 Gbps” ports (Gen 2)
   • USB-A 3.0 ports: up to 5 Gbps 

• Display Technology / Mode:
   • Uses MST (Multi-Stream Transport) for extending multiple displays (i.e. splitting the single USB-C’s video streams)

• Physical / Mechanical:
   • Dimensions: 145 × 70 × 20 mm
   • Weight: ~305.6 g 

• Compatibility / Notes:
   • Works with Windows, macOS, Linux, etc. (typical USB-C host devices) 
   • On macOS, there may be limitations: all external displays might mirror the same content (no extended mode) due to macOS’s handling of multiple MST displays. 
   • The extra USB-C port on the hub does not support video output (only data) according to reviews.
