Our take
Choose WL-UMD09 for a host-checked multi-display desk where the mix of video, USB, network and card ports justifies a larger dock. The key compromise is host-dependent MST behavior plus a separate PD adapter and an 85W, not 100W, laptop-output ceiling.
A Windows-oriented desk setup needing multiple displays, wired network and card access, after checking the exact host's DP version, MST behavior and adapter requirements..
It is not a safe choice when macOS extended MST desktops are required, when the computer lacks USB-C DP Alt Mode/compatible Thunderbolt, or when the laptop needs more than the listed 85W host output.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- WAVLINK documents two HDMI outputs and a DisplayPort output with a detailed host/DP-version mode table.
- The port list includes two USB 3.x, two USB 2.0, Gigabit Ethernet and SD/microSD readers.
- The maker distinguishes up to 100W PD input from up to 85W passed to the host.
What to weigh up
- macOS mirrors MST displays rather than extending separate desktops.
- The display mode depends on the host, DP version and Windows/MST support.
- The charger is sold separately, and the historical ASIN and 11/12-in-1 count are unresolved.

Full review: how the features affect your choice
What the features mean for you
Built around three monitor outputs and MST
WL-UMD09 provides two HDMI ports and one DisplayPort output from a USB-C host, plus USB, network, card and audio connections. This makes it a fuller desk dock than a single-display dongle. The manufacturer describes it as 11-in-1, while an official-store listing and the frozen historical title call it 12-in-1; compare the actual port diagram rather than using the number alone. Its three video connectors are not a promise that every laptop can run three separate external screens at the highest resolution.
Display mode depends on the computer and operating system
WAVLINK requires a USB-C port with DisplayPort Alt Mode or a compatible Thunderbolt connection. Its mode table lists up to 4K/60Hz for one display with DP 1.4, but triple extended displays on Windows drop to 1920×1080 at 60Hz with DP 1.4 DSC 1.2, 30Hz without DSC, or 1600×900 at 60Hz with DP 1.2. The manufacturer says macOS mirrors MST displays instead of extending separate desktops. Check the host GPU's simultaneous display limit and DP version before selecting this dock for a multi-monitor workspace.
USB and network ports cover both older and newer devices
The dock has two USB-A ports rated by the manufacturer up to 5Gbps and two USB-A 2.0 ports rated up to 480Mbps, along with Gigabit Ethernet and an SD/microSD reader. That is a useful mix for a desk with both storage and low-bandwidth accessories. The source does not state the aggregate bandwidth when multiple functions are active, so individual port ratings do not guarantee simultaneous peak rates. Confirm the card format and decide which peripherals belong on the faster ports before setting up a workflow with storage, network traffic and video at once.
Power delivery is capped below its input rating
WAVLINK specifies up to 100W input and up to 85W passed to the laptop, with a compatible adapter sold separately. The difference matters: the dock does not promise to deliver the full input rating to the computer. Confirm your laptop's charging demand and the power adapter you plan to use. The official Q&A also says the host USB-C connection needs charging support for pass-through. If the computer displays a slow-charge warning, the source recommends checking the adapter and host port rather than assuming the dock can meet every system's power needs.
Confirm the model and historical listing separately
The manufacturer page provides a strong specification record for WL-UMD09, but it does not map the frozen ASIN B0BY1HMF52. This review therefore uses an exact-model Amazon search, not a direct product link. Inspect the result for model WL-UMD09, the two HDMI plus DisplayPort layout, card reader and PD adapter requirements. Choose it when its documented MST behavior fits the host and monitor plan; avoid relying on the 12-in-1 label alone or expecting extended dual screens under macOS. No hands-on testing, buyer-review consensus or current price/stock claim is used here.
Choose the display plan before routing desk cables
The mode table makes the tradeoff concrete: a single display can use the listed 4K/60Hz DP 1.4 mode, while three extended Windows screens run at lower resolutions and depend on DSC and the host's DP version. Decide whether the workstation needs one sharp display or several independent screens before arranging the dock, cables and laptop position. A three-connector count does not tell you which output combination your computer can drive, and the macOS mirror behavior may defeat a multi-desktop plan. Check the source mode table against the exact computer and operating system first.

Before you buy
Can macOS extend separate MST desktops across its outputs?
WAVLINK says macOS mirrors MST-connected displays.
Does it pass 100W to the laptop?
No. The maker specifies up to 85W to the host from a 100W input.
Will any USB-C host drive the displays?
No. The maker requires DP Alt Mode or compatible Thunderbolt, with modes varying by host and DP version.
