Hi StevenI have a Lenovo 440T with a powered USB port, the computer runs the drive fine even when I use the light scribe. The unit also has a port where you could run a power supply to the unit as well. I very happy with the unit.

the device is USB Powered. Just plug into available USB port on you computer and go to work

You will need an 120 volt power supply... most cell phone charger transformers will work fine

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.

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.

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.

It's both USB powered AND has an external power supply. It has both. The AC power supply is provided for in situations where the device does not have sufficient capacity to power the Pawtec External 3.0 cd/DVD r/w, etc. device. This is more likely to happen with iPads, cell phones and other lower powered devices. Some netbooks might not have enough power, either. Hence, the product comes WITH an external power supply. Hope this helps.

Both. You can use USB only, but if you need more power, you can use an ancillary A/C power cable. I have not needed to use the A/C cable with mine, but perhaps I have not stressed it as much as other people have.

No. It just plugs in. Be sure to install it with airflow going in the proper direction for proper cooling.

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).

You just plug it into the computer via USB drive and set it up that way and you are ready to go. No other power source needed.

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

You have to have AC to power it. The smaller, "min" versions of the g-tech drives are able to be bus powered. Strangely, on the amazon pages per the technical details, in the "Special Features" section, it says "usb powered". However, upon looking at the g-tech web site and other resources, this likely just refers to it having usb ports...more of a marketing term than a technical term. I reviewed the technical manual, product guide and datasheet on the site for the product with no mention of being able to use the USB to power it. I will try with mine at home but I have had mine for a little over 6 months and had it AC powered the whole time. I would not expect a workhorse like that to be able to be bus powered.

Powered by USB, whether off laptop, desktop, or direct plug with a USB port. I love it!

It has a built in power supply and ac cord. Does not use USB or wall transformer

Can use the A/C adapter instead of batteries. Have not tried to power it with just the USB, but it might work.

Yes, it does require AC power. It comes with a power adapter to plug into the wall. Very simple unit and does exactly what it sets out to do. I recommend.

Hi, you don't need the ac power supply but I went with it ti have more power and I am glad I did, would do the same next time !

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

No, is not, but came with a usb cale and you can plug at any ac power do you have.

I don't think this hub is built to deliver that kind of power. All my external USB hard drives are separately plugged into the A/C. At minimum, your drive would probably have to be plugged into multiple USB ports.

If you want only usb cable, yes. It is not AC powered, though. I use one to supplement an AC powered 4-port USB hub.

I use one of these myself, and yes every PSU has to be plugged in to an ac outlet.

Yes it does require AC to work. It does come with a power cable. Very nice unit only had mine installed about a month but works great.
