UGREEN 90307
UGREEN 90307 Powered 7-Port USB 3.0 Hub
A powered desktop USB-A hub with seven individually switched data ports, visible LED status and an included 12V/2A supply for a more stable multi-peripheral workstation.
Product introduction
Overview
UGREEN 90307 expands one computer USB connection into seven accessible USB-A 3.0 ports. Each port has its own switch and indicator, allowing a device to remain plugged in while its connection is turned off without removing the cable.
The seven data ports share one upstream USB path rated up to 5Gbps. This is useful for mixed low-bandwidth peripherals and periodic storage work, but it is not seven independent 5Gbps channels. Actual transfer speed depends on the host controller, device, cable, file pattern and simultaneous traffic.
An included 12V/2A supply provides up to 24W to the hub and attached devices. Exact product media identifies four ports as charging-capable, but does not publish a reliable individual fast-charge wattage. Use the labels on the exact unit and allow each connected device to negotiate or draw only what it supports.
At a glance
Key features
Port-by-port clarity
Seven switched ports with external power
Seven USB-A ports
Connect compatible USB data devices; all ports share the single upstream host link.
Individual switches
Turn each port connection on or off without unplugging its cable. Confirm the LED state before accessing storage.
Charging-capable group
Four ports are shown as charging-capable in exact media, but no per-port fast-charge wattage is promised.
12V DC input
Use the included 12V/2A supply to power the hub and stabilise a multi-device load.
Port control
Keep a wired desk organised with per-port switches
Individual switches are useful for equipment that stays connected, such as a printer, scanner, card reader, keyboard, mouse or service cable. Turn on only the port required for the current task, then wait for the operating system to recognise the device.
Switching off a storage port is electrically similar to disconnecting it. Always eject the volume first; an LED or switch does not replace the operating-system safe-removal process.
- Label frequently used cables to match the switch row.
- Eject drives before switching their port off.
- Power the hub before attaching several high-draw devices.
Powered operation
The included 24W supply supports the shared peripheral load
The external 12V/2A supply gives the hub a larger power budget than a bus-powered splitter. It helps when several devices are connected, although the total 24W must still be shared and does not create an unlimited charging station.
Exact media identifies a four-port charging group, but charging speed remains dependent on the port design, connected device and cable. Use a dedicated charger when a known USB Power Delivery or fixed fast-charge profile is required.
- Use only the correct included-voltage supply.
- Place the adapter and hub in a dry, ventilated location.
- Do not calculate four identical high-power outputs from the 24W total.
Real-world applications
Use scenarios
Choose this exact model when its verified connections and limits match the workflow below.
Permanent desktop peripherals
Leave keyboard, mouse, printer, scanner and card reader connected while controlling each port independently.
Drive service bench
Attach several external drives for sequential access, with the hub powered and storage ejected before switching.
Media workspace
Connect card readers, control surfaces and low-bandwidth accessories while reserving bandwidth for one active storage transfer.
Shared device station
Provide visible, individually controlled USB connections in a lab or office without repeatedly wearing connector sockets.
Practical connection order
Setup and usability guidance
A deliberate connection order makes capability checks and troubleshooting easier.
- Place the hub on a hard, dry surface with the switches accessible.
- Connect the included 12V/2A supply to the hub, then to a compatible mains outlet.
- Connect the upstream USB cable to the computer.
- Turn on one port and attach a low-power peripheral to verify host recognition.
- Add remaining devices one at a time and watch their LEDs and operating-system status.
- For storage, complete and eject the volume before turning its switch off.
- Use the labelled charging-capable ports only for devices whose requirements fit the hub.
- Disconnect the mains supply before cleaning or inspecting the hub.
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.
USB-A computers
Windows, macOS or Linux desktops and laptops with a USB data host port and support for the attached peripherals.
Common peripherals
Keyboard, mouse, printer, scanner, card reader, flash drive and external storage within shared power and bandwidth.
Lower-speed USB
USB 2.0 and USB 1.1 devices can negotiate their lower native rates.
Charging devices
Only on the exact charging-capable ports and within the shared 24W supply; no universal fast-charge promise is made.
Verified function scope
What this product does

Boundaries that prevent a mismatch
What this product does not do
- It does not provide seven independent 5Gbps links.
- It does not guarantee a particular charging wattage or fast-charge protocol on every port.
- It does not safely eject storage when a switch is pressed.
- It does not add display, Ethernet or card-reader functions by itself.
- It does not replace device-specific drivers or dedicated high-power chargers.
Recommended practice
What to do
- Use the included correct-voltage power supply.
- Eject drives before switching their ports off.
- Connect high-bandwidth storage one transfer at a time for predictable speed.
- Keep the hub and adapter ventilated and dry.
- Check the exact port labels before using a connection for charging.
Avoid common mistakes
What not to do
- Do not use an unverified replacement DC adapter.
- Do not switch off a port during a write operation.
- Do not assume every port supports the same charging role.
- Do not expect 5Gbps simultaneously from all seven ports.
- Do not cover the power adapter or hub with fabric or paper.
Read before use
Warnings and limitations
Check before connecting or ordering
- The hub uses an external 12V/2A supply; use the correct voltage and fully seated connector.
- Seven ports share one up-to-5Gbps upstream link.
- Switching a storage port off without ejecting the volume can corrupt data.
- Exact media identifies four charging-capable ports, but no verified per-port wattage or universal fast-charge protocol is published.
- The 24W adapter output is a total hub budget, not 24W available to each port.
- Connected specialist peripherals may require their own drivers.
- The host cable is approximately 3.28ft according to the current exact product material.
Warning / limitation 1

Model-specific answers
Product-specific FAQ
Can each port be turned off separately?
Yes. Each of the seven ports has its own switch and LED. Safely eject storage before turning its port off.
Does every port support 5Gbps at once?
No. The seven ports share one up-to-5Gbps upstream connection, so simultaneous transfers divide available bandwidth.
Is the 12V/2A adapter included?
Yes. Exact package information lists a 24W 12V/2A power supply.
Can I use a different DC adapter?
Use the included supply. An adapter with the wrong voltage, polarity or connector can damage the hub or peripherals.
Which ports can charge devices?
Exact media identifies a group of four charging-capable ports. Follow the labels on the unit; no verified individual wattage is promised.
Does each charging port provide 24W?
No. 24W is the total adapter output shared by the hub and all connected devices.
Is it a USB-C host hub?
No. It is a USB-A data hub for a computer host, with seven USB-A downstream ports.
What happens if I switch off an external drive?
The computer sees a disconnection. Eject the drive first and wait for writes to finish to reduce corruption risk.
Why is a device not detected even though its LED is on?
The LED shows basic power/switch state. Check the host link, device cable, driver and shared power, then test the device alone.
Can it output video?
No. It is a USB data and peripheral-power hub with no HDMI, DisplayPort or USB-C video output.
Will it fast-charge every phone?
No universal protocol or per-port fast-charge figure is verified. Use a dedicated charger when a defined charging profile is required.
