Exact SKU 25053
Revodok Max 208 Thunderbolt 4 Dock
A powered desktop dock for high-bandwidth storage, displays, Ethernet and USB-A devices.
Product introduction
Overview
UGREEN 25053 is a powered desktop dock for high-bandwidth storage, displays, ethernet and usb-a devices.
This page separates connector ceilings from real simultaneous performance, explains host requirements before purchase, and names the functions this exact model does not provide.
Research used exact live UGREEN India media and exact-SKU official UGREEN material; Accepted exact gallery: 3 downstream TB4, 85W host, 15W downstream and mandatory 140W adapter. Rejected blanket dual-display claims for base Apple chips, tablets and plain USB-C hosts.
At a glance
Key features
8-in-1
One compatible display can reach up to 8K30; a compatible dual-display setup can reach up to two 4K60 displays.
Thunderbolt 4
The 40Gbps figure is the maximum theoretical host-link rate, shared by displays, Ethernet, all three downstream TB4 ports and all USB-A devices.
Dual 4K60
Connect the supplied 140W DC adapter before the host; the dock is not designed to operate unpowered.
85W host power
Single- or dual-monitor Thunderbolt workstation
Port-by-port clarity
Every connection explained
Thunderbolt 4 upstream host
40Gbps host link and up to 85W laptop power; connect the computer here.
3 × downstream Thunderbolt 4
Up to 40Gbps link, display capability and up to 15W accessory power per current exact-SKU gallery.
3 × USB-A 3.2
Up to 10Gbps per port for storage and peripherals, subject to shared host bandwidth.
RJ45 Gigabit Ethernet
10/100/1000Mbps wired network connection.
140W DC input
Required external power input; the supplied adapter powers the dock and host-power path.
Display planning
Resolution, topology and host limits
One compatible display can reach up to 8K30; a compatible dual-display setup can reach up to two 4K60 displays.
The display path uses downstream Thunderbolt 4 ports; suitable USB-C/Thunderbolt display adapters or displays are required.
Base Apple chips and other host models have their own external-display limits. Pro/Max-class and Intel Macs differ; verify the exact Mac before promising two screens.
A full-featured USB-C host without Thunderbolt is limited to the video and bandwidth its USB-C implementation exposes; do not market this as universal dual display.
Shared resources
USB, card and network performance
The 40Gbps figure is the maximum theoretical host-link rate, shared by displays, Ethernet, all three downstream TB4 ports and all USB-A devices.
A 10Gbps USB-A device remains limited by its own controller, cable and storage media. Three ports cannot each sustain independent full link maximums indefinitely.
Gigabit Ethernet requires a Gigabit router/switch and Cat5e-or-better cable.
Power path
PD input, host delivery and included power
Connect the supplied 140W DC adapter before the host; the dock is not designed to operate unpowered.
Up to 85W can reach a compatible laptop through the upstream port; 140W is the adapter rating, not laptop charging output.
Each downstream Thunderbolt 4 port is advertised up to 15W, but the complete power budget is shared with the host and dock.

Practical connection order
Setup and usability guidance
- Confirm the exact SKU on the product or invoice.
- Check the host port for required video, data and charging roles.
- 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.
Host and peripheral fit
Compatible devices and systems
Thunderbolt 4 and Thunderbolt 3 computers
Compatibility means only the functions exposed by the specific host port and operating system; connector shape is not enough.
USB4 computers with compatible display/power implementation
Compatibility means only the functions exposed by the specific host port and operating system; connector shape is not enough.
Selected full-function USB-C laptops and tablets with reduced capability
Compatibility means only the functions exposed by the specific host port and operating system; connector shape is not enough.
Windows 10 or later and macOS 11.4 or later as listed

Verified function scope
What this product does
- Adds three downstream Thunderbolt 4 connections
- Supports one high-resolution or two compatible 4K displays
- Provides up to 85W host power when externally powered
- Adds three 10Gbps-class USB-A ports and Gigabit Ethernet
Boundaries
What this product does not do
- It is not bus-powered; the DC adapter is mandatory.
- It does not guarantee dual displays on every Mac, tablet or USB-C laptop.
- It does not create Thunderbolt capability on a USB-C-only host.
- It does not provide HDMI, DisplayPort, card-reader or 3.5mm audio sockets.
Recommended practice
What to do
- 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.
Avoid common mistakes
What not to do
- 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.
Read before use
Warnings and limitations
Warning / limitation 1
Keep the ventilation slot and aluminium housing uncovered; warmth under multi-port load is normal.
Warning / limitation 2
Use the marked upstream port for the host. A downstream TB4 port is not a substitute for the upstream connection.
Warning / limitation 3
Do not use phone or Nintendo Switch examples from unrelated listings; exact official compatibility material excludes or does not qualify them.
Warning / limitation 4
Disable HDR as a troubleshooting step if the laptop freezes, as noted in exact official regional guidance.

Model-specific answers
Product-specific FAQ
What exact model is this?
This guide is for UGREEN 25053 only. Similar UGREEN hubs and docks can use different video, data and charging controllers.
What must my USB-C host support?
Use a host that supports the connection and operating-system capabilities stated in this exact-SKU guide.
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?
Connect the supplied 140W DC adapter before the host; the dock is not designed to operate unpowered. Up to 85W can reach a compatible laptop through the upstream port; 140W is the adapter rating, not laptop charging output.
Is the wall charger included?
Yes, the verified package list includes the external power adapter stated above.
Does it support an external display?
One compatible display can reach up to 8K30; a compatible dual-display setup can reach up to two 4K60 displays. The display path uses downstream Thunderbolt 4 ports; suitable USB-C/Thunderbolt display adapters or displays are required.
Can I use it with a Mac?
Windows 10 or later and macOS 11.4 or later as listed
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.
