Features
What it does well.
Key features
Quick reference
Understand the host, downstream ports and shared limits
Connections and roles
Attached host plug. The cable ends in USB-A male for a computer or another USB-A host. It is not a USB-C hub.
Four peripheral ports. Each downstream socket is USB-A 2.0 female for compatible keyboards, mice, printers, drives, controllers and accessories.
Auxiliary power input. A Micro-USB input can provide supplemental power for the hub and connected devices; it is not a USB data input.
One shared upstream bus. The four ports do not each receive a separate 480Mbps link; simultaneous traffic shares the single USB 2.0 upstream connection.
Four convenient ports for everyday peripherals
Data expansion
Use the hub to group a keyboard, mouse, printer, scanner, controller, camera, flash drive or other USB 2.0-compatible device at a desk. The one-metre attached lead helps place the hub where its top and side ports remain accessible.
USB 2.0 is well suited to human-interface devices and many legacy peripherals. Large storage transfers are limited by the 480Mbps shared bus and by the speed of the drive, host port and operating system.
Plug-and-play hub operation on supported systems; individual peripherals may still need drivers.
The LED provides a simple power or connection indication.
Backward-compatible USB 1.1 peripherals operate at their supported lower speed.
Bus power is limited—especially with several devices
Power planning
A USB 2.0 host port has a limited power budget. Low-power keyboards and mice are typical fits, but spinning hard drives, optical drives, fans, charging phones and several peripherals together can exceed what the computer supplies.
The auxiliary Micro-USB input can improve power stability when a suitable external source is connected. It does not bypass device compatibility, raise data speed or turn the four downstream ports into independent fast-charging outputs.
Use self-powered peripherals where their manufacturer supplies an AC adapter.
Connect high-demand storage directly to the computer when diagnosing disconnects.
Do not rely on this data hub as a four-port phone charger.
Use scenarios
Real-world applications
Good fits for a USB 2.0 expansion hub
Keyboard and mouse desk setup. Move low-bandwidth input devices to an accessible hub while keeping the computer’s remaining ports free.
Printer, scanner or label device. Connect compatible office peripherals; install the peripheral maker’s driver when required.
Controllers and receivers. Attach supported game controllers, wireless receivers or simple USB accessories to one host port.
Occasional flash-drive access. Read or copy files from USB 2.0-compatible flash drives while recognising the shared speed and power limits.
Compatible devices and systems
Device and system fit
Best with USB-A computers and ordinary USB peripherals.
USB-A computers. Windows, macOS, Linux, ChromeOS and other computers with a working USB-A host port and normal hub support.
USB-C computers. Require a separate data-capable USB-C-to-USB-A adapter. The adapter and host must support USB host operation.
Phones and tablets. Not direct-fit. A compatible OTG adapter and operating-system support are required, and connected-device power can be limited.
Peripheral types. Suitable for many keyboards, mice, printers, scanners, controllers, card readers and low-power USB storage devices.
Check before buying
Important limitations
Check these points before ordering or connecting:
Confirm the host provides USB-A. This model does not have a USB-C host plug despite an erroneous legacy specification field.
Plan around the attached 1m cable; the older India paragraph says 80cm, but the title and regional product data identify this SKU as 1m.
Add the current requirements of every connected peripheral. Several high-power devices can exceed a USB 2.0 host port’s bus-power budget.
The 480Mbps figure is shared across all four ports and will not provide USB 3.x storage speed.
If using a phone or tablet, confirm USB host/OTG support and obtain the correct adapter separately.
This is a USB data hub, not a docking station: it has no HDMI, Ethernet, memory-card, audio or USB Power Delivery function.
What this product does
Function scope
Use this model for the functions listed below.
Expands one USB-A host port into four USB-A 2.0 peripheral ports.
Carries USB 2.0 data with up to 480Mbps shared signalling bandwidth.
Supports USB 1.1 devices at their lower mutually supported speed.
Provides an auxiliary Micro-USB power input for added bus-power stability.
What this product does not do
Function boundaries
These boundaries prevent a connector or headline specification from being mistaken for a different function.
It does not provide four independent 480Mbps links.
It does not serve as a four-port fast charger or USB-C Power Delivery charger.
It does not add HDMI, Ethernet, audio, card-reader or other dock functions.
It does not connect directly to USB-C, Micro-USB or Lightning hosts.
It does not remove the need for a peripheral driver, application or its own power adapter.
Setup and usability guidance
Setup guidance
Place the hub on a stable surface where its top and side ports are accessible.
Connect the attached USB-A plug directly to a working computer host port.
Wait for the operating system to recognise the hub. No separate hub driver is normally needed.
Connect a keyboard, mouse or one low-power peripheral first and confirm operation.
Add remaining devices one at a time while watching for disconnects or power warnings.
For extra power stability, connect a suitable Micro-USB power source to the auxiliary input; do not treat that input as a data connection.
Install only the peripheral manufacturer’s required driver, and safely eject USB storage before unplugging it.
Do and avoid
Good practice
Use it for USB 2.0 data expansion and low-power peripherals.
Connect directly to the computer while troubleshooting.
Add peripherals one at a time so a power or driver problem is easy to identify.
Use self-powered storage or the auxiliary input when the device maker requires more power.
Eject storage safely and keep the hub dry and ventilated.
Do not use the hub as a multi-phone charging station.
Do not expect USB 3.x transfer speed from any downstream port.
Do not overload the host power budget with several spinning drives, fans or charging devices.
Do not force a USB-C plug into the USB-A host connector or downstream sockets.
Do not unplug storage while files are being written.
Warnings and limitations
Safe operation and troubleshooting
Use it safely and troubleshoot methodically.
Safety / limitation 1. USB 2.0 bus power is limited. A connected device can disconnect or fail to start when the combined demand is too high.
Safety / limitation 2. The auxiliary Micro-USB input can supplement power but does not change the USB data standard or guarantee operation with every high-demand device.
Safety / limitation 3. All four ports share the upstream 480Mbps signalling ceiling, so simultaneous transfers compete for bandwidth.
Safety / limitation 4. A USB hub can be plug-and-play while a printer, scanner, controller or other peripheral still requires its own driver.
Safety / limitation 5. Stop using the hub if the cable, housing or port is damaged, unusually hot, loose or contaminated.

FAQs
Questions buyers ask.
Is the host connector USB-A or USB-C?
USB-A. this product image and regional model data show an attached USB-A male plug. An older India specification field saying USB-C is inconsistent.
How many USB ports does it add?
It adds four USB-A 2.0 downstream ports from one USB-A host connection.
Does each port get 480Mbps?
No. Up to 480Mbps is the shared USB 2.0 signalling ceiling for the single upstream link.
Can I charge four phones from it?
It is designed primarily as a data hub, not a multi-port charger. USB 2.0 bus power is limited and no fast-charge output is specified.
What is the Micro-USB port for?
It is an auxiliary power input that can improve power stability for the hub and attached devices. It is not another data port.
Is a Micro-USB power cable included?
No auxiliary power cable or adapter is identified in the package contents. The listing specifies the hub with its attached USB-A cable.
Can it run an external hard drive?
A low-power drive may work, but spinning or high-demand storage can exceed host bus power. Use the drive’s approved power arrangement or connect direct when diagnosing.
Will it work with a USB-C laptop?
Only through a suitable data-capable USB-C-to-USB-A adapter. This hub itself has a USB-A host plug.
Can I use it with a phone or tablet?
Only if the mobile device supports USB host/OTG mode and you use the correct adapter. Power and peripheral support vary by device and operating system.
Does it need a driver?
The hub is normally plug and play on supported systems. A connected printer, scanner or other peripheral may still need its own driver.
Why do devices disconnect when several are connected?
The combined power demand or shared bandwidth may be too high. Remove devices, connect direct, add auxiliary power if appropriate and test one peripheral at a time.
