How is the device powered? Do I have to buy extra AC adapter?

No, it actually comes with a power cord. You connect the cord to the bottom of the front of the device and plug it into the wall. I prefer it to battery powered.

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.

from what I understand, it now includes a USB cable to power the device, previous versions included a power adapter. I wish there are more details on what else has been upgraded. (if there are other stuff that is)

I believe mine came with an AC Adaptor. I don't USB would be enough even if it was an option.

It does not require the use of the AC adapter, it will work without the AC adapter being plugged in. It will only work, however, as good as any non-powered USB hub, meaning, there would be a limit to the amount of power that can be used by the devices connected, some devices will require the additional power, that is the advantage of the additional AC Power source.

It is powered off the USB bus. I use an adapter plugged into 110 volts to insure constant adequate power (because some USBs have more power than others).

It requires auxilliary power. USB won't power it. But it comes with a power pack.

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

It is AC only. It just has a basic power cord. I really do not know why they call it portable, since it does not take batteries or charge with internal battery.

Steven it is USB powered but comes with a second USB cable to provide extra power if required. In my experience it seems to be needed. Regards John Docherty.

it is powered through the USB cable ,, most devices have powered USB ports it's rare these days to find non powered USB ports

there's two things you need to plug in - the power adapter and the usb cable. The usb cable it uses is a regular mini-usb (like the kind old blackberries used)

It requires a power adaptor to be plugged, but one comes with the item, however you will need an AC outlet nearby as the power cord is only 30 ins long or you can attach it to an extension cord.

It comes with the AC adapter. I use this one on my work bench, so I use it plugged in. I have a different one at my desk that is battery powered. Both of them work well.

Hi jody it is powered by both,the ac plug adapter and then the battery for backup.only thing though the battery keeps falling out when moved to fill so I finally just taped it and that holds it in but wasn't happy for the price that is has that flaw.

It's battery powered so you have to buy batteries. I believe it can be powered with AC adapter but it doesn't come with it.

You just need a USB charger to power the unit. The power supply voltage is immaterial.
