UGREEN CM498 15600 • NINE-PORT DESK EXPANSION
HDMI, VGA, wired network, cards and USB in one dock
UGREEN CM498 / SKU 15600 expands one compatible USB-C host port with HDMI and VGA display connections, three USB-A 3.0 data ports, Gigabit Ethernet, SD and microSD readers, and a dedicated USB-C Power Delivery input.
Product overview
Overview
A clear view of the product before you connect it
This dock is built for mixed modern and legacy workspaces. HDMI connects a current monitor, television or projector, while VGA supports an older display. Three USB-A ports add storage and peripherals, Gigabit Ethernet provides a wired network path, and separate SD and microSD readers support common camera-media workflows.
The HDMI connection supports up to 4K at 30Hz and the VGA output supports up to 1920 × 1080 at 60Hz. Both display outputs can be connected, but the host, operating system and combined-display mode determine whether the screens mirror or extend and which common resolution is available.
The dedicated USB-C PD input accepts up to 100W from a compatible charger. It is a power input rather than a data port. Actual host charging is lower because the dock uses power and the computer accepts only its negotiated level.

TWO DISPLAY STANDARDS
Connect HDMI and VGA displays without a second adapter
The HDMI output is intended for a digital screen and supports up to 4K at 30Hz. VGA supports older displays up to 1080p at 60Hz. This combination is useful in offices, classrooms and meeting rooms where the available projector connection is not always predictable.
When HDMI and VGA are active together, the host and operating system control the display arrangement. Combined operation can require a shared lower resolution, and some systems mirror the two external outputs rather than creating independent desktops.
- One HDMI output, not dual HDMI
- One VGA output
- VGA carries video only
- USB-C host must support video output
- Use the operating-system display panel to choose mirror or extend
DATA, NETWORK AND CARDS
Build a stable everyday workstation
Three USB-A 3.0 ports support keyboards, mice, receivers, flash drives, card readers and compatible storage. Their maximum 5Gbps figure is theoretical and all traffic shares the single upstream USB-C connection.
The RJ45 port supports Gigabit Ethernet when the host, driver, cable and network equipment all support that rate. SD and microSD slots provide convenient access to camera and mobile-device media.
- Use Cat5e or better cable for Gigabit Ethernet
- Actual network speed is limited by the router, service and host
- Safely eject drives and cards
- Do not expect all ports to sustain maximum throughput simultaneously
PASS-THROUGH POWER
Use one host connection while charging the laptop
Connect a suitable USB-C PD charger to the marked power input when the laptop needs charging or several peripherals require steadier power. The dock accepts up to 100W input, but the host receives less after dock consumption and power negotiation.
A 100W-capable setup requires a charger that provides the necessary USB-C PD profile and a suitable 5A E-Marker cable. Lower-powered chargers remain limited to their own rated output.
- PD port is charging input only
- Charger and charging cable are not confirmed as included
- Power Delivery does not add video support
- Disconnect power before inspecting damaged cables or connectors

Warnings and limitations
Safety note 1
Use the CM498/15600 port labels as the definitive connection guide: one HDMI, one VGA, three USB-A data ports, Gigabit Ethernet, SD, microSD and PD input.
Safety note 2
HDMI and VGA used together can lower the available resolution or mirror content depending on the host. Confirm the required display arrangement before relying on two external screens.
Safety note 3
High-power drives, several USB accessories and charging draw from the available host and PD power budget. Reduce devices if connections reset.
Safety note 4
Mild warmth is normal under sustained load. Stop use if there is unusual heat, smell, noise, port damage or cable damage.
Safety note 5
A wired link does not guarantee internet speed; results depend on the router, switch, cable, network service and host software.
