It is a firewire hard disk drive designed to take advantage of the faster than usb 2 FW port. I personally use it for time machine, to back up permanently my iMac, and because of that it needs its own power supply to function. It does not operate only by connecting it to the computer. It needs the power supply to operate.

No, it runs approximately 1 hour and a half. Then you have to plug it into power

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

It plugs into a standard 110 wall outlet. It's like any other computer you would buy only with the large touch screen that makes it like an iPad. Had it 8 months now and it's the best computer I've ever owned.

I'm not sure what it uses by just being plugged in. It's max capacity is supposed to be 2400 watts. I have a computer plugged into it that is always running as well as a few other things in my recording studio that always use a little power. I don't think it uses much on it's own. I have 4 of them in different locations and I haven't seen any increase in my electrical bill using them.

It gets all its power from the computer's bus. It does not need power from an electrical outlet.

No, you do not need a separate power source. The cooling pad can be powered through a USB port on your computer. I choose to use a separate source to keep the USB port open for other devices.

Our power cord came with the computer and it runs on house current all the time. It doesn't have a DVD or CD outlet but we love it.

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.

It comes complete with an external power source. You plug the external power source into any standard outlet. There is a wire attached to the source - I think it's about 4 feet long, but I never measured. Plug the wire into the unit, and you are good to go. I ***BELIEVE*** that it is self-powered through the USB input port, but I always use the external power supply, as it takes the load off of the power supply built into a laptop or desktop computer. NOTE: You can use a standard household extension cord to reach a wall outlet. Plug the power supply into the extension cord, then plug the cord into the outlet.

It runs off batteries but you need a connect to the computer. Mine had one with it.

It has its own power supply. One weird thing about it is that it only turns off when you turn your computer off. And since my Mac is never shut off, this thing has been on since the day I bought it. Doesn't seem to be a problem though.

It plugs directly into a power outlet. We've had it about two years now and it works pretty well

No, to power it, it came with a USB cord that can connect into a USB port on a computer or USB wall adapter.

Comes with its own power supply. It has a 110 AC household plug. The cord is a little short but I had no problems making it work.

Yes, it plugs into a standard wall outlet. It also has a cord to connect it to your computer, but I have not used it.
