The power source for the Fantom drives is a plug-in low voltage dc transformer (12v I think), so you'll have to have a available AC outlet near where you want to use the drive. If you are buying the USB 3 model you should get good throughput with the USB connector. If you have an eSATA connection on your PC you'll get considerably better data transfer speeds.

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

I have two of these drives and have had them for a minimum of 18 months. I have never had any problems with them. They work fine. They came with an AC power adapter as well as a USB cable.

Power source is not USB. Comes with 12 VDC power adapter. Has two different data interfaces: USB 2.0 or eSATA. Use either one at a time, but not both. I have found the USB interface to be more reliable, although a bit slower, but not by much.

This hard drive comes with an external power supply module that plugs into a wall outlet. It is not a wall-wort but is a 4 x 2 x 1-inch block that comes with a removable cord that plugs into the wall and a second cord that will plug into a power connector on the hard drive unit, both cords are long enough to allow convenient connections. These are very good drives, I have four that are working very well. If your computer provides external eSATA connections, the drives that can accept this interface are MUCH faster than the USB 2.0 drives.

Its totally USB powered. Because its critical, I plug it into a powered USB hub. Its performed quite well and I'm quite satisfied with it. You can spend more and get a hardier controller, but you still get value in excess of the asking price here. Even when I upgrade, I'll keep it as a spare. Its a good tool.

A USB port uses a max 500ma of +5vdc power = 2.5 watts. Thanks for using AnswerParty!

it comes with power and a micro usb cable to connect to the computer. this thing is really awesome. i usually keep 2 usb sticks, 2 1tb drives, a couple other usb license keys connected. i also keep my iphone and android phone connected too. it will fully charge them in about an hour. for 10 bucks, it is definitely worth it. i may end up buying a couple more.

It is 3.0. I suspect the box image is from a previous model. Interesting note, the USB connection is split; 1 for USB 3 and 1 for power. If you plug into the USB 3.0 port you do not need to plug in the other connection for power. The USB 3.0 powers it just fine. The extra power connection is for 2.0 connections I believe.

Powered by one USB port. Pretty awesome and fast even in USB 2. It's USB 3 cable.

This drive is USB powered - it actually features dual USB connections in case one is underpowered on your computer. There may also be an option to use a separate power supply but I have not tried that.

From what I see, the USB slot is for INPUT from a PC, or a car lighter plug power adapter that you supply.

I use a powered usb hub. So I can plug many things into the hub and it has it's own power pack. Then I don't overload the onboard power from the pc.

There is an on/off power switch but you can easily leave the switch to 'on' and utilize the USB cord as a power cord, so that when you plug it into your computer it will automatically kick on.

the drive requires the usb cable only! power is provided by your computer through that cable.

No way I can see. It is powered by the USB connection and data is moved the same way. There is no other connection.

It is USB. The industry standard is +5 Vdc. USB always has been and always will be +5.

USB is nothing but Universal Serial Bus, basically serial ports with differential pair pins, also the pin-outs are different than older RS232C interface.To answer, yes it comes with power and USB cables.

You use a usb cable to connect to the computer, which also provides the power you'll need.
