Does this need USB Power or one AC Adapter?

when connected to pc, the USB port gives this unit the power needed to operate, no ac adapter needed. the usb cable will come with 2 connector, it's recommended that both of them are connected given the fact that one of the connector is an extension from the other connector for some extra energy.

The hard drive enclosure comes with a MiniUSB adapter that powers the hard disk when plugged into your PC via USB.

There are 2 power sources. You can either plug in to USB or the wall for it to work.

It depends on your computer. My lap top is the same as yours, one usb on each side. For me, this device works with one usb connected. THe second is for power inn the even it does not get the power needed.

Hi Steven -- I run it on a single USB alone, but it also comes with a second USB cable/jack for extra power. I haven't needed it. Overall happy so far.

Mine came only with a USB cord, no AC plug. Good luck -- it seems to be inconsistent!

Yes, this needs usb power to function at all. You don't have to use the sound, but usb is always necessary.

Hi Jon,The unit is USB powered. You dont need a seperate power unit. The USB cable is included.

The device does require external power. It cannot run off of USB or eSATA power alone. So, yes, it does plug into an AC outlet if that is what you are referring to.

None... However, you must USE a separate power supply for the adapter. You must use at least 5 volts @ 2 Amps or 2000 mili-Amps or higher. It is use to power up what ever device that you going to use. Having a USB to power cord which came with the adapter is NOT good enough. My adapter plugs in deep into my laptop. I have problems with some USB devices because of the thickness of the USB end. It gets in the way of the laptop case. I use an extender to help resolve that problem.

No AC adapter was included in the one I bought from Amazon; but the whole unit runs off USB and you most likely won't be using it without a computer as it's meant to control your DAW (digital audio workstation).

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

No external power required. Only needs a USB port with enough power. Most standard USB 3 ports should be adequate.

It is not USB powered, it comes with an AC adapter... however, a word of caution; when I purchased this it came with a "travel" AC adapter meant for outlets in Europe and will not work with US outlets. I had to research to find the correct AC adapter to get it to work and they ended up giving me a refund. It does work though, if you find to correct AC adapter which might be too much trouble for most people looking for a simple solution.

AC adapter. It's two pieces actually. You have a Mini USB to USB then a USB to US outlet.

No, it does not come with an AC adapter. It is powered by the USB connection. I have had no problems with just using the USB connection as a power source.

You shouldn't need an AC adapter, it has a cord that draws power from the USB port included. If you want to power it with a separate power source, you would need to use one that has a USB plug on it. USB is a standard 5 volt DC, although the milliamps will vary.
