It requires a standard AC outlet. It does not plug into USB at all, it gets the audio from a headphone outlet.

No, it is powered by plugging into an electric outlet. The USB provides a connection into your computer. This not a bus powered drive, neither it is portable.

You can plug it into your computer or into the wall with a USB wall adapter. This doesn't come with the USB wall adapter.

You need to plug it in the wall with the electric cable. Then connects to the computer with the USB cable.

USB powered. So far I am loving it. The convenience of being able to move it from one computer to another is a great benefit.

it plugs into the power supply directly. Then plug into the wall or surge protector of your choice.

You can plug it into your computer or a wall outlet if you have a wall adaptor that connects to a USB cable.

Yes, the USB plugs in, then attaches to the power adapter that goes into your wall. If that's what your question means.

It plugs into the USB port of any computer. There is no further power required.

It is powered by an internal battery. It is charged by a charger that comes with it. The charger plugs into a wall outlet, it is not a usb charger.

Completely powered via USB. Has a double USB cable to plug into two USB ports should your computer not supply enough power. Works like a champ.

Comes w/a split cable -- 1 end goes into a USB port, the other end has a plug w/a green end which goes into a green hole in the back of your computer. I think it gets the power from the USB port, but I'm not sure. It's not battery-operated.
