I had been using another coupler and I was getting less than 100 Mbps speed. Hence I decided to try Ugreen coupler. I had bought a 1000Mbps and this one. Both saved me from the hassle of changing the entire cable.

Place the hub/dock on a stable, open surface; place stand models before loading a device.
Connect required external power before the host when the model requires or benefits from it.
Connect the host using the marked upstream lead or port.
Attach one display first and confirm a stable picture before adding others.
Add Ethernet, storage, cards and low-speed peripherals one group at a time.
Configure display arrangement, resolution and refresh in the operating system.
Eject storage/cards before unplugging; disconnect high-power accessories before packing.

What this product does
Function scope
Raises a laptop/tablet through four angle levels
Folds for travel and cable routing
Adds one HDMI output, two USB-A ports and two card slots
Supports 5Gbps USB and card rates up to 104MB/s as advertised
What this product does not do
Boundaries
It does not charge a laptop through Power Delivery.
It has no Ethernet or audio jack.
It does not support two external monitors.
It is not intended for devices larger/heavier than the listed fit range without a stability check.
What to do
Recommended practice
Match the SKU before ordering.
Use qualified display, Ethernet and USB-C cables.
Connect external power when specified or when bus-powered storage is unstable.
Keep firmware, OS and relevant drivers current.
Test the simplest connection first, then add devices.
What not to do
Avoid common mistakes
Do not assume every USB-C port carries video, data and power.
Do not add individual port maxima to claim an aggregate throughput.
Do not cover the hub or place it on heat-trapping fabric.
Do not remove storage/cards during writes.
Do not force connectors, stand hinges or devices that do not fit.
Warnings and limitations
Read before use
Warning / limitation 1. Place both feet fully on a stable, level desk before loading the stand.
Warning / limitation 2. Keep laptop cooling vents clear; the open frame helps airflow but cannot prevent overheating caused by blocked vents.
Warning / limitation 3. Do not adjust the stand while a heavy laptop is unsupported.
Warning / limitation 4. Check that a protective case fits the rails and does not make the device unstable.

FAQs
Questions buyers ask.
What model is this?
This guide is for UGREEN 80551 only. Similar UGREEN hubs and docks can use different video, data and charging controllers.
What must my USB-C host support?
For video, the host USB-C port must support DisplayPort Alt Mode. Data and charging functions also depend on the host port's own implementation.
Can every port reach its maximum at the same time?
No. Displays, USB storage, cards and Ethernet share the upstream host link and available power. Individual port labels are ceilings, not simultaneous aggregate guarantees.
Will it charge my laptop or handheld?
this model has no USB-C PD input and should not be sold as a charging dock. Bus-powered accessories draw from the host; high-power external drives may need their own power.
Is the wall charger included?
No wall charger is listed in the base package unless your retailer explicitly sells a charger bundle.
Does it support an external display?
One HDMI display is supported up to 4K30 when the host USB-C port supports DP Alt Mode. The stand cannot add video output to a data-only USB-C connection.
Can I use it with a Mac?
MacBook, Windows, Chromebook and USB-C tablet models that physically fit
Is driver installation required?
The native USB/DP Alt Mode functions are designed to be plug-and-play. Keep the operating system, GPU, USB/Thunderbolt and network drivers current. No DisplayLink claim is made unless explicitly stated.
Is it normal for the hub to become warm?
Some warmth is normal when converting video, network, data and power in a compact enclosure. Keep it uncovered and disconnect it if heat becomes abnormal or operation unstable.
What should I check if a display is blank?
Confirm DP Alt Mode, reconnect power where required, use a qualified display cable, select the correct monitor input, lower resolution/refresh, and update host graphics/USB drivers.
Can I disconnect it while copying files?
Stop transfers and safely eject storage or cards first. Removing the hub during a write can corrupt open files or the filesystem.
