    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?

    Mini 4-port USB 3.0 Travel Hub
    Mini 4-port USB 3.0 Travel Hub
    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.

    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.
