    How long are both the USB cable and the AC adapter?
    A shopper on Dec 23, 2017
    BEST ANSWER: The cord that is attached to my 4-port USB 3.0 hub is about 11 inches, and the length of the cord for the AC Adapter that came with it is about 4 feet.
    Does this get enough power through the USB Bus to operate 4 devices simultaneously, such as flash drives or external hard drives, or would the PID: 21671 be better suited for that?

    BEST ANSWER: USB 3.0 spec states that upto 900 mA per port may be consumed. So for a truly compliant USB 3.0 hub, need as a minimum 4*900 = 3.6A power supply. Since the supplied adapter is rated @ 2A, no this hub is not fully compliant. If your downstream ports are consuming lower current than this 900 mA then you may be ok but is like playing roulette.
    Can this be used as a stand alone charging station?
    A shopper on Feb 15, 2018
    BEST ANSWER: Good question and hadn't thought about that option. I unplugged it from my PC and plugged in two phones and my phone iPad and all three showed charging off the wall adapter. So it will work for at least three devices.

    Data connection works, doesn't seam to charge phone
    I have this connected to a USB port on my computer. without extra power, it doesn't charge an iPhone 6. I used a USB to power cable to connect to extra power, that didn't help. I then tried the AC adapter, also didn't seem to help. So as far as I can tell, this can't be used to charge a phone at all.

    With that said, a 2.5" hard drive was connected, and it appears to work.
