Is the power adapter required at all times? or does it also function in USB power mode only?

Thank you for your question. This hub can function directly with USB cord connected. Power supply is not necessary when using low power consumption devices. Should you have any questions don't hesitate to contact us again. Thank you.

It requires a USB 3.0 connection on your motherboard. There are no other power requirements. It is not compatible with USB 2.0 motherboard connections.

Actually the manual does mention that an external power adapter is available if the attached device needs more power than the ExpressCard can supply. It's on page 2. Frankly, it seems to me, the vast majority of people will be better served by running the supplied USB 3.0 cable from the card to a powered USB 3.0 hub. This avoids any power issues in the first place.

It does not have a power on off button, USB hubs I have had in the past with power adapter did not have a power button. you need to plug in the power adapter and it will remain on till it is pluged in to AC, if you disconnect the AC adapter it will function as a normal USB hub but will not be usable for charging devices that are power hungry. You could still charge cell phones or smaller devices. Hope this clarifies.

Although the user manual does not say that it needs a power source, it came with a USB cable. I was not sure why, later I noticed that the device has a mini USB port on the side. I had it connect to my Cable box that has a USB port. The device did not work properly (it kept flickering) without using USB cable. It works perfectly now.

Mine also came with a power adapter. The adapter is pretty small in a small box so be careful not to lose it.

Yes, this needs usb power to function at all. You don't have to use the sound, but usb is always necessary.

You shouldn't need an AC adapter, it has a cord that draws power from the USB port included. If you want to power it with a separate power source, you would need to use one that has a USB plug on it. USB is a standard 5 volt DC, although the milliamps will vary.

No it does not have any power adapter at all. It's not a very quality item, and we're very disappointed with this purchase since we cannot even use it. Good luck!

None... However, you must USE a separate power supply for the adapter. You must use at least 5 volts @ 2 Amps or 2000 mili-Amps or higher. It is use to power up what ever device that you going to use. Having a USB to power cord which came with the adapter is NOT good enough. My adapter plugs in deep into my laptop. I have problems with some USB devices because of the thickness of the USB end. It gets in the way of the laptop case. I use an extender to help resolve that problem.

no, you need the included ac adaptor(is a 12v output), usb is only 5v output.

There are one cable USB to an -Mini USB (http://en.wikipedia.org/wiki/USB) in the packet. Its Powered by the USB, no need for extra power.

It doesn't come with an AC power adapter. Instead, it has two USB cables: one to interface with the computer and the other supplies power to the unit.

A power adapter is included, but you'll need to purchase a USB A to B cable (male to male) if you plan to connect it to a computer.

The unit comes with a power adapter but you don't need to use it. I have a ext HD, wireless mouse/ keyboard combo controller and my UPS USB cable hooked up to it without the power adapter plugged in.

It is USB 3.0, no adapter needed, or provided, and there is no place to plug in one even if you wanted to - draws any needed power from the USB 3 port.

It comes with a power adaptor and a USB cable. The power adaptor is required to power the disk drive.
