    Do the 7 port units come with LED power indicators for the individual switches?
    Robert H on Aug 10, 2017
    BEST ANSWER: Yes they do!! Note: I use mine plugged in to ac power too, not just phantom from the computer. The LED is for each switch, and you press the button to power on and off. The LED doesn't automatically light up when you plug something in, you have to press the button for that port. I hope I was clear.
    How long is the AC adapter cable?
    A shopper on Dec 22, 2017
    BEST ANSWER: The cable is about 36 inches long
    Work without being plugged into a computer?
    James H on Aug 28, 2017
    BEST ANSWER: Hi, hubs that comply with USB 3.0 (or 2.0) standards are not ideal for stand-alone charging without being connected to a computer. This is because USB standards have requirements for how power is handled so that ports only have minimal power until a device is detected. Without a computer connection, some devices will not charge at all, some devices may show slow charging only, and others may show charging status.

    For a stand alone multi-charger, instead of this USB 3.0 data hub, products 13914 and 13915 would be better solutions. Thanks for checking.
    I just received this unit and it appears the USB has to be plugged into the computer for charging to occur. Is this true?

    If so, do you have a product that does not require to be plugged into a computer to continue charging devices?
    James H on Aug 28, 2017
    BEST ANSWER: Hi, that is correct, based on USB 3.0 standards, USB hubs would usually have to be plugged to a computer to enable more current to charge mobile devices, otherwise the ports might only provide minimum power that won't be sufficient for charging. Using the hub in the way you described as a stand-alone charger is not ideal and could get mixed results depending on the mobile device. Some mobile devices might not charge at all, some devices could indicate slow charging only, and still some devices might simply show the device is charging (we got these results when we tested this setup with different devices).

    For a stand-alone multi-device charger, the following products would be great solutions: 13915, 13914. Thanks for checking.
    what are the specifications for the external power supply for both the 7 and 10 port units?
    A shopper on May 8, 2017
    BEST ANSWER: They have 5V 3A external power adapters for use with USB devices that need more power than typical USB peripherals.

    Great usb hub that works!
    This is a great piece of equipment. Nicely designed and fits under my screen on my desk.
    It powers all of my peripherals with no problems.
    I particularly like the off/on keys for things like my webcam.

    Has worked perfectly so far
    It actually has fast speeds for everything (just a note, I have kept it plugged in to ac power too, not just plugged in to computer). I have my 2 main external HDD's plugged in to it, and it is nice to have it right at the front of the desk to plug whatever other USB stuff I desire.

    Good quality Hub
    I received the Hub and after connecting it, no problems. Does the job it's supposed to do and I like the button to control each port individually. It is a good accessory at a reasonable price.

    Much better than my last hub
    Solid product. Doesn't lose connection, even when the power is disconnected.

    This Hub does the jobw
    My laptop was out of USB ports even with a docking station. This 7-port hub gives me the room for more attached devices.. There is a switch for each port and it is powered, so no worry about overloading the main USB port. I don't use this as a portable device. It remains attached to the docking station at my desk.

    It work good being plugged into a computer.

    If you plug it into a router for network storage it does not do too well. You are limited to 1 hard hard.
