12 reviews for 4 Port USB 3.2 Gen 1 Mini High-Power Hub w/ Port Status LEDs

  1. Michael Congelo

    Great Quality Mountable USB Hub
    When it comes to finding an externally powered USB with actual mounting hardware, it is very slim pickings. This was one of the few products that fell into my requirement for that, though it’s a bit of an oversight that this doesn’t come with any screws to do so. The negative reviews almost scared me off, but I took my chances and I have received a quality product. All USB ports are in working condition, albeit a tight fit when plugging and unplugging. It does exactly what you’d need a USB hub to do. However, the power supply could definitely use a longer cable. It makes it a bit difficult for cable management when you have only a 3 foot or so cable to do so. The actual hub is made of metal and feels of high quality. Would definitely recommend at this moment in time if you’re looking for a hub that you can mount to a desk.

    Works as Promised
    There was a definite improvement in response time. Of All my peripherals after changing to this hub.

  3. DangerTeenager

    Great Quality
    Works perfectly. It’s the only mountable usb 3.0 hub that I found. Great quality and value.

  4. Mike

    This is a good little hub, solidly built, and fast.

    There’s not much to tell about this little hub; it’s good for an environment where it might get bumped or hit, and can be mounted to ensure it doesn’t get knocked across the room when it’s bumped or hit!

    I imagine most people who would be interested in this one, is because it’s mountable. Indeed, it has 4 little slots for where screws would go to mount it.

    Alas, it comes with no screws…

    But I dug around in my drawers for some screws that would fit it, and eventually was able to mount it where I needed it, and it has been working great ever since!

    I wish the included cable was a bit longer, so consider getting a USB 3.0 extension cable (I got one from Amazon, works great).

    Considering you get no screws, a short cable, and only 4 ports, the (current) $34 price tag seems a bit high, but for what it’s intended for, it works great.

    USBGear Model #USBG-4PminiH – 4-Port USB 3.0 High-Power Metal Hub for PC or MAC – Certified Chip

    Because of its small size, I decided to purchase this mini hub. After using it, this is a great 4 port mini USB 3.0 hub for tight space applications or organized connections for several of your USB 3.0/2.0 devices.

    First Visual Observations:

    I was surprised to find a Sunday delivery, the item had been delivered in a padded envelop boxed in the manufacture’s box. The item’s box itself was a thin white box approximately 8 inches long by 1 1/2 inch high.

    The Mini USB 3.0 hub was received packaged neatly in the manufactures box that included:

    – Hub’s power supply
    – USB 3.0 A to Mini-B cable
    – USB 3.0 hub
    – User manual

    The Mini Hub is small enough that will fit into a small space no bigger than your open hand. The USB 3.0 cable connectors are a tight connection into the USB 3.0 Mini-B port as is the power supply connector needed when using the hub for devices with higher constant power consumption requirements.

    Hub Operation:

    I used a Windows 8.0/8.1 (ASUS) laptop with the operation of this hub. My basic process with hubs is to connect the USB cable to the hub, then the cable to the host USB port. This laptop is very quick so I had checked my device manager for the connection; the “Generic SuperSpeed USB Hub” was listed in my Universal Serial Bus Controllers list.

    I should note that this hub has a (Red) Power LED and becomes brightly illuminated with the hub connected to the computer’s USB port. The power supply this hub comes with is only for additional power, not for initially powering the hub, the USB 3.0 Type-A to Mini-B cable must be connected as this is the medium for transferring the data.

    This is a 4 port USB 3.0 hub, USB 3.0 is backward compatible with USB 2.0/1.1 devices which is what I am using with this particular hub. Backward compatibility means that the hub will operate USB 2.0 devices through its USB 3.0 ports but will only have USB 2.0 data transfer speed (480Mbps). Once my connection was made, I had plugged in several thumb drives, when a USB device is connected the hub’s corresponding “Green” LED becomes active indicating that particular port is connected.

    The thumb drive data instantly appeared on my screen and I was able to browse folders very quickly as I would when accessing my hard drive. Using the thumb drives in my case was the intent of purchase of the USB 3.0 mini hub. Although I didn’t mount the hub in any way, it does include mounting flanges as part of its construction to accommodate for mounting to a table top or wall. There are no screws included but looks like standard mounting screws (two on each side) will work.

    Based on my usage of it so far, this hub has a good, solid chassis construction, all ports including the power port have a tight connection and it is instantly recognized by my Windows system, I did not have to go through a separate installation process for it to do what I needed, switching between data sources was just a matter of opening folders to that thumb drive.


    Being as small as it is, I would recommend this USB 3.0 4 Port Mini Hub for tight places may require some sort of hub integrated into its equipment or out in the open where multiple port connections need to be made, possible in an office, school or industrial environment. It was operational as soon as I connected it.


    – Extremely small and capable piece of equipment for running multiple USB data sources
    – Easily connects to a Windows system running 8.0/8.1
    – Includes LED for power and individual port connection
    – Backward compatible with USB versions 2.0/1.1
    – Worked right out of the box


    I found no CONS with this device’s function, worked right out of the box.

    Additional Information:

    The USB 3.0 Mini Hub’s power supply adapter is labeled:

    – Input: 100-240V – 50-60Hz 1.5A
    – Output: 5V – 4000mA

Hubs F.A.Q.

Product F.A.Q.

View frequently asked product questions below. Still need help? Reach out!

  • Can the hub be used without a power supply?
    In some cases, yes. USB peripherals that only require low power (i.e. keyboards & mice) can be used without a power adapter. Power in this case is drawn from the host’s USB port.

    When high-power USB peripherals are used, a power supply for the USB hub may be required. In other cases, the USB peripheral may require their own power adapters, in this case, a power supply for the hub may not be required. Without ample power though, the USB hub or connected peripherals may not operate correctly. It is recommended to use an included power supply when possible.

  • After waking up from sleep mode, my computer/host no longer recognizes my USB device.
    If the USB device does not function properly after your computer or host has been in sleep mode, it is likely that Windows turned off the USB Root hub in order to save power.

    To prevent this, follow the steps below (depending on your operating system).

    Windows 10 / 8

    1. On your keyboard, press the Windows key + X and select Control Panel.
    2. Click Hardware and Sound, then click Power Options.

    5. Click the plus sign (+) next to “USB settings” and “USB selective suspend setting” to expand the options and change the setting to Disabled.
    6. Click OK to apply the setting.

    Note: You may need to disconnect and re-connect your USB device after applying these settings.

    Windows 7 / Vista

    1. Click the Start button and select Control Panel.
    2. Click Hardware and Sound, then click Power Options.
    3. Click Change plan settings for the plan you want to change.
    4. Click Change advanced power settings.
    5. Click the plus sign (+) next to “USB settings” and “USB selective suspend setting” to expand the options and change the setting to Disabled.

  • The hub is properly hooked up, but is not functioning correctly. What can I do?
    Testing all setup components is the best place to begin troubleshooting. To determine the source of the issue, individually test your:

    • USB Cable by using it in another setup, or trying another cable.
    • Host USB Port by connecting another device or thumb drive.
    • Connected Peripherals by connecting directly to the host.

    Moving on to troubleshooting the hub itself. Attach a USB peripheral. The USB hub itself will not appear in hardware listings on your host’s system. USB devices connected however, will appear when connected. If the connected device is still not being found, try:

    • Installing the required drivers for the USB peripheral.
    • Install the most recent drivers for the USB controller and/or motherboard chipset.

    USB hubs do not require drivers or software.

    Troubleshooting the desired USB peripheral may be in order. If the peripheral is still not being recognized, attempt:

    • Attaching external power to the peripheral, if required.
    • Confirming if the peripheral functions on a standard USB port.
    • Testing if basic USB peripherals work, such as keyboards or mice.
  • How can external power be connected to the industrial USB hub?

    External power is supplied by connecting to the terminal block located on the hub. For when an external power adapter is required check out the Accessories & Replacement Parts section on this product page. To view all of our hub accessories and power supplies, visit the category here.

    To determine the power requirements, the equation to use is P = 5 * I * N, where:

    P is the power wattage.

    is the USB port voltage.

    I is the current of the USB port in Amps (USB 2.0 is 0.5A, USB 3.0 is 0.9A.

    N is the number of USB ports.


    As an example using the equation, a 4 port hub would reflect a minimum wattage of 18 watts.

    Knowing the minimum requirement, a proper power adapter can be chosen. In this case the voltage of a power supply should be within 7 to 24 or 7 to 40 Volts DC, depending on the specifications of the USB hub. Also, the power supply must convert AC to DC (no AC output).

    Power supplies often come with a voltage (V) rating and an amperage (A) rating. To determine the current in amps, use I = P / V, where the following is true:

    I is the current of the power supply.

    P is the calculated power of the hub.

    V is the chosen voltage of the power supply

    Continuing the example, the 4 port hub requires 18 W and the power supply you choose is 12V, the current of the power supply would be I = 18/12, I = 1.5A.
