UGREEN 30758
UGREEN 30758 4-Port 10Gbps USB-C Data Hub
A compact aluminium data hub that expands one USB-C host connection into two USB-C and two USB-A ports, with a fixed 25cm braided cable and up-to-10Gbps shared bandwidth.
Product introduction
Overview
UGREEN 30758 is a four-port USB-C data hub for adding modern USB-C peripherals and conventional USB-A devices to a computer, tablet or phone with a compatible USB-C host/OTG connection. The two connector types share one compact aluminium enclosure and one fixed upstream cable.
Each downstream connection is intended for USB data. The USB-C ports do not output DisplayPort video and do not provide USB-C Power Delivery charging. This distinction matters because the connector looks identical to a full-function USB-C port while implementing a narrower role.
The stated rate is up to 10Gbps through the single upstream USB connection. It is shared across concurrent transfers and depends on the host controller, operating system, peripheral, storage media, cable and file workload. A USB 2.0 device continues to work at its own slower rate.
At a glance
Key features
Port-by-port clarity
Four data ports with no display or charging path
USB-C host lead
The fixed approximately 25cm braided cable connects to a USB-C data/OTG host.
Two USB-C data ports
Attach USB-C storage and peripherals; these ports do not carry display output or Power Delivery charging.
Two USB-A data ports
Use flash drives, keyboard, mouse, card reader and other compatible USB-A peripherals.
Shared upstream link
All four devices share the single up-to-10Gbps connection and the host-provided power budget.
Connector mix
Use USB-C and USB-A peripherals without separate adapters
The mixed port layout is useful during a transition between USB-A and USB-C storage. It can keep a keyboard and mouse connected while a USB-C drive or card reader is attached, provided the combined host power and bandwidth are sufficient.
Connector shape does not change the function. Both downstream USB-C sockets are data-only. A USB-C monitor, laptop charger or phone expecting Power Delivery will not gain those functions through this hub.
- Use direct data cables rated for the required speed.
- Connect one high-speed storage device at a time for predictable transfers.
- Check the host OTG/data setting on phones and tablets.
Shared performance
10Gbps is the link ceiling, not four independent channels
When one fast SSD is active, it can use much of the available upstream link. Starting a second transfer divides controller, link and host resources, so both operations can slow even though every device remains connected.
The fixed short cable reduces desk clutter, but it must not be used as a carrying strap. Support the hub and attached plugs so their combined weight does not twist the host USB-C socket.
- Eject drives before removing the host cable.
- Test a slow device alone before diagnosing the hub.
- Use auxiliary-powered peripherals when their own design requires external power.
Real-world applications
Use scenarios
Choose this exact model when its verified connections and limits match the workflow below.
Mixed storage desk
Connect one USB-C SSD, a USB-A flash drive and low-bandwidth accessories through one USB-C host.
Laptop port expansion
Add four accessible data sockets where a slim computer offers only one available USB-C port.
Tablet file import
Attach a compatible card reader or storage device when the tablet supports USB host/OTG and the filesystem.
Portable service kit
Carry a small aluminium hub with a fixed cable for keyboards, mice, installers and data drives.
Practical connection order
Setup and usability guidance
A deliberate connection order makes capability checks and troubleshooting easier.
- Confirm that the host USB-C port supports USB data or OTG.
- Connect the fixed USB-C lead directly to the host.
- Wait for the standard USB hub to enumerate.
- Attach one low-power peripheral and verify detection.
- Add high-speed storage one device at a time and use rated data cables.
- Install only the driver required by the attached peripheral.
- Eject storage through the operating system before unplugging it.
- Coil the short lead loosely and protect all connectors during travel.
Host and peripheral fit
Compatible devices and systems
Connector shape alone is not enough: the host port, operating system, cable, display and peripheral must support the required function.
Windows and macOS
Compatible USB-C computers using standard USB hub support; individual devices may require drivers or filesystem support.
Linux and ChromeOS
Compatible hosts with USB-C data support; verify specialist peripheral drivers.
iPadOS, iOS and Android
Devices with USB-C host/OTG support can use compatible peripherals within available power and OS limits.
USB peripherals
USB-C and USB-A storage, keyboards, mice, card readers, printers and other data devices.
Verified function scope
What this product does
- Adds two USB-C and two USB-A data ports to one USB-C host.
- Supports USB data up to the shared 10Gbps interface ceiling.
- Works with lower-speed USB devices at their negotiated rates.
- Provides a compact, fixed-cable connection for common peripherals.
Boundaries that prevent a mismatch
What this product does not do
- It does not output HDMI, DisplayPort or USB-C video.
- It does not charge the laptop, tablet, phone or connected USB-C device through Power Delivery.
- It does not give each downstream port an independent 10Gbps lane.
- It does not increase the host power budget for high-draw peripherals.
- It does not make an unsupported filesystem or device driver compatible.
Recommended practice
What to do
- Use a 10Gbps-capable host and peripheral for the highest available rate.
- Keep high-speed data cables short and properly rated.
- Support the hub instead of letting it hang from the computer port.
- Eject storage before removal.
- Test devices individually when diagnosing power or bandwidth limits.
Avoid common mistakes
What not to do
- Do not connect a monitor to a downstream USB-C port.
- Do not connect a charger expecting host pass-through power.
- Do not pull or carry the hub by the fixed cable.
- Do not start several large writes if predictable speed is important.
- Do not unplug storage while files are open or being written.
Read before use
Warnings and limitations
Check before connecting or ordering
- The India URL handle ends in 30759, but the exact live title, SKU and media identify product 30758.
- The host requires USB-C data/OTG capability.
- Downstream USB-C ports do not support video output or charging.
- All four ports share one up-to-10Gbps data path.
- Available peripheral power comes from the host; high-draw devices may need their own supply.
- The fixed braided host cable is approximately 25cm and cannot be replaced separately.
- Approximate body size is 3.7 × 1.5in; leave room for four attached plugs.
Warning / limitation 1
High-draw storage can exceed the power available from a tablet or laptop port.
Warning / limitation 2
Concurrent transfers share bandwidth and may reduce one another’s speed.
Warning / limitation 3
USB-C connector shape does not imply video or charging support on the data-only ports.
Warning / limitation 4
A damaged fixed cable cannot be swapped like a detachable lead; stop use if strain relief or insulation is compromised.
Warning / limitation 5
Unexpected removal during a write can corrupt files or a filesystem.

Model-specific answers
Product-specific FAQ
Why does the India URL say 30759?
The current handle has that suffix, but the active title, live variant SKU and exact media identify this product as 30758.
Do the USB-C ports support monitors?
No. They are data-only and do not carry DisplayPort Alt Mode video.
Can the hub charge my laptop?
No. It has no USB-C Power Delivery input or host pass-through charging function.
Can a downstream USB-C port charge my phone?
No charging function is specified. Use a dedicated charger rather than the data-only ports.
Does each port run at 10Gbps?
No. The four ports share one up-to-10Gbps upstream connection.
How long is the host cable?
The fixed braided host cable is approximately 25cm.
Does it work with a phone or tablet?
It can work when the device has USB-C host/OTG support, enough power and OS support for the attached peripheral.
Why is my SSD slower than 10Gbps?
10Gbps is the interface ceiling. The host, SSD, cable, files, filesystem, thermal state and concurrent traffic determine real speed.
Can I connect USB 2.0 devices?
Yes. They operate at their own lower negotiated rate.
Is a driver required?
Modern systems generally use a standard USB hub driver, while a specialist peripheral can require its own driver.
Why does a drive disconnect?
Test it alone, check its cable and confirm the host provides enough power. The hub has no auxiliary-power input.
