    4-Port USB 3.0 HUB w/ AC Adapter - 5V/3.8A

    Maintain SuperSpeed connectivity for all your external USB devices with this 4-port USB 3.0 Hub from Monoprice!

    This hub features four USB 3.0 ports, which are capable of reaching speeds of up to 5.0 Gbps, while at the same time maintaining full backwards compatibility with USB 3.0/1.1/1.0 devices. It comes with a 5 VDC, 3.8A power supply, allowing it to provide the full 900mA power output required for self-powered devices (e.g., 2.5" portable hard drives) on all four ports.

    The hub measures only 4.5" wide, 1" high, and 2.8" deep. It features power and activity LEDs on the front, so you can always know the status of your connections. It uses a USB 3.0 micro-B connector for the connection from the computer, so it can only be connected to a USB 3.0 port.

    How long is the USB cable?
    Benjamin R on Dec 12, 2016
    BEST ANSWER: The USB cable is about 3 feet long but remember, Monoprice sells all kinds of USB extensions if you need them.
    Do you need the power supply for just a keyboard and mouse?
    Christopher F on Aug 2, 2017
    BEST ANSWER: Hi, you can skip the external power supply and connect directly to a computer USB port if you are just using the hub with a mouse, keyboard, and most other low power peripherals. The external power supply is useful when using devices that draw more power, like external hard drives for example. Thanks for checking.

    Yup, It's a USB 3.0 Hub
    It's quite hard for me to get wildly worked up about this hub. I mean, It's a USB 3.0 Hub.

    It has power. It has a nice long cable for plugging it into your machine and putting this on your desk. It works every time. Basically the review to me on this would either be a 1 or a 10. It does exactly what it's advertised to do, and it does it for a lot less than every other one I saw out there. I'm happy.

    PROS: It's a USB 3.0 hub with power.

    It does the hub thing really well

    CONS: It doesn't plug itself in.

    Great price, good hub.
    Good little USB hub. Nice that it includes the power adapter and USB 3.0 cable as well.
    I found the USB 3.0 cable too short, another foot on it would be great.

    I have had occasional drops with this unit, but they appear to have been related to initial setup.

    This is based on the Via Labs 812 chipset, rather than the more common 810, or 811 chipset. This could potentially be an issue in terms of post sale service, and firmware updates as I do not believe Monoprice is the actual manufacturer of this unit. With the D-Link USB hub I have (810 based), I can use the 810 firmware from a different brand of USB hub though as D-Link stopped supporting it.

    PROS: Price
    Speed (more than 200MB/s over USB 3.0 to a 2-HDD RAID-0).
    Power ( More than enough power to charge an iPhone and iPad)

    CONS: Occasional drop outs.
    USB cable may be too short.

    As a note to the reviewer from Corvallis, OR on this note:
    "Cons: proprietary USB-3 cord with plug - can't be reused for other products."
    FYI, That's a USB 3.0 micro cable that came with it. It is not proprietary. It is a standardized cable, and is used on such devices like the Samsung Galaxy S5 and Note 4.

    PROS: Looks nice, comes with Micro USB3.0 cable for data transfer/charging supported devices.

    Couldn't get working with Raspberry Pi.
    I saw the 7 port USB hub that was compatible with Raspberry Pi, but I didn't need as many ports. So I ended up buying this four port USB adapter. I tried tinkering around with it, and couldn't get it to work. The Raspberry Pi is able to run off the hub, but is unable to recognize the USB Mouse, Keyboard, or any other device. I have also tried powering the Raspberry Pi unit separately with still no luck. If anyone was able to get this device working with Pi, it would be great to see how you got it working, as this is a perfect sized/styled unit.

    PROS: Nice USB hub if you want to use with Windows 7. Nice looking design, and good quality.

    CONS: Couldn't get working with Raspberry Pi.

    lasted one year
    The hub had only one drive connected to it behind another hub. Everything on the other hub worked fine but this one kept dropping and losing my drive with three partitions. I plugged the drive into another hub and it worked just fine didn't lose the connection once. So take your chances. Mine lasted one year. I have two others of different brands and they work just fine.

    Although most stuff from Monoprice has been good to me this is the exception.

    PROS: works

    CONS: stops working

    Good USB 3.0 Hub
    Bought this with skepticism after buying a dud from eBay. This turned out to be much better and totally reliable so far. I keep two USB 3.0 external HDs (WD) and a Kingston USB 3.0 card reader and has worked flawlessly at amazing speed. I'm happy to learn about monoprice from a co-worker.

    PROS: Works well with my late 2012 iMac.

    CONS: None so far.

    Excellent POWERED USB 3.0 Hub
    This one was a little more expensive than some items listed on eBay. I bought it because I needed an externally powered hub and so many sellers have "USB powered" hubs (instead of a powered USB hub, which supplies its own via an adapter).

    This hub works great. Its durable too, as while I was unpacking I dropped it about 5' onto concrete and it only suffered some minor cosmetic damage.
