My hub came with the AC adapter that I need to just plug into a standard AC outlet. If your came without the adapter I would contact the vendor addressing the problem.

My Fantom drive does have an AC adapter - not pulling power from the desktop.

Mine came with a power brick, for what it's worth. I believe that this hub corrupted my external usb 3.0 hdd, and pretty much killed it. Don't know this for a fact but I don't use it anymore.

I was unable to use this device because when I purchased it I thought an ac adapter would be included as part of the "accessories" sorry I couldn't help.

The adapter I have is AC powered and not battery operated. I don't understand the question: "without AC adapter..." and "rather than battery operated." If it is not powered by AC or a battery, how is it supposed to be powered. This unit plugs into an earphone receptacle on the computer. These ports don't supply power like a USB port does. I don't think my answer helps much.

In the switching adapter there are informations that may help you:OUTPUT : +5v - 4AThis output is the hub input.

I did not use the connectors. I removed them and wired it direct. Working great!

There is no ac adapter, only a usb cable which can be plugged into a computer.

Hi Bobby K - No. I remember having to buy the AC Adapter separately...but it was not very expensive...maybe $ 20.00

The hub does not run on batteries but does run on 100 to 240 volts AC power.

The AC adapter is a wall wart that plugs into a 120v receptacle to supply power to the hub. This allows the hub to power the devices that are plugged into it. I always prefer to have a USB hub supply power to the devices and not pull their power from my PC.

The USB hub doesn't need one for most devices, the AC adapter that comes with can also easily be replaced with a universal one you buy locally.I am using it just with the USB power fine.

Computer operates on batteries which last a long time (~2 years for my first batteries). I don't see any site for an ac adapter to be attached.

Make sure you take out the adapter for the plug. It's small so it can be missed.

Correcting my message, the AC Adapter is OPTIONAL. I just found where I bought it with the Radio.

AC adapter provided.. Otherwise, you can purchase an AC plug with USB ports.

That other answer is not entirely correct. A powered hub can operate on USB power only. It does not NEED to be plugged into AC. It will work the same as an un-powered hub, which will limit you to a total of 500mA of current draw from all ports combined. However, if you use the AC adapter then you will have up to 500mA per-port (2A total). So if you are only going to connect low powered devices, or self powered devices, then the AC adapter can be considered optional. If you need to connect devices that draw more power (portable hard drives, USB powered scanners, burners, etc.) then you would need to use the AC adapter to supply the additional power.
