UGREEN USB C Hub 10Gbps 4 Port Aluminum USB 3.2 Splitter 2 USB-C 2 USB-A Data Ports Laptop MacBook PC Type-C Hub (30758)
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.
What it does well.
Key features
At a glance
Four data ports with no display or charging path
Port-by-port clarity
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.
Use USB-C and USB-A peripherals without separate adapters
Connector mix
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.
10Gbps is the link ceiling, not four independent channels
Shared performance
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.
Use scenarios
Real-world applications
Choose this model when its 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.
Setup and usability guidance
Practical connection order
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.
Compatible devices and systems
Host and peripheral fit
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.
What this product does
Function scope
- 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.
What this product does not do
Boundaries that prevent a mismatch
- 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.
What to do
Recommended practice
- 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.
What not to do
Avoid common mistakes
- 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.
Warnings and limitations
Read before use
Check before connecting or ordering.
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.
- 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.

Model-specific data
In-box information
No charger, external power adapter, display cable or connected peripheral is identified as included.
Questions buyers ask.
Why does the India URL say 30759?
The current handle has that suffix, but the active title, live variant SKU and 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.
