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.

Yes, when individual switches are turned on there is a blue led indicator light where the numbers are approximately the color blue of the blue showing in the USB ports in the picture

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?

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.

Do you have to use the power supply or can you simply use the power from the computer?
Kathy F
on Nov 16, 2018
BEST ANSWER: Hi, power from the computer works for low power peripherals. Using the power supply ensures there is enough power for multiple devices so it is still highly recommended especially for high speed data applications.

Do the buttons have to be pressed each time the computer is powered up in order to select each USB device that you want to connect? I'm looking for a USB hub that will be inaccessible, that will have anything that is plugged into it enabled each time the computer is turned on.

Did not live up to its potential. Not sure why.
I needed this to connect an external USB 3.0 hard drive and peripherals to my DJ laptop, which has a 3.0 USB port. When testing it before a show, my laptop did not consistently recognize the HDD, which was not acceptable. I reverted to my trusty old USB 2.0 hub and now use this one for less critical home use instead. Of course, it works fine there for some reason. I really wanted this to work for me.

Not Stoked. Don’t buy if you need it to do anything besides charging.
Doesn’t really work. It’s fickle. I wanted a hub that I could just plug anything into and have it work, but I still have to use all my old ports, and it only works with certain things. It’s no good for data transfer. It’s only good for charging. Not stoked.

So many ports. So many options.
I'm a producer/audio engineer. My laptop only has 3 USB 3.1 ports so I used to have to decide between plugging in my Corsair keyboard (which uses two USB ports), audio interface, MIDI keyboard, any external storage devices, mouse, and other peripherals. Now that I have this thing, I have more than enough USB ports. Hasn't let me down yet.
