Is it battery powered or powered by the actual device?

It is powered by the external device. I don't notice much power drain though when I use it with an iPad. If you are accustomed to weighted keys on keyboards or pianos, this keyboard may take some time to get used to.

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.

It is battery powered. You can probably get a wall wart adapter at Radio Shack.

It's battery operated. But don't worry, it doesn't work with batteries, either.

yes it is a battery operated device. I am not sure what is on the disk. I have used these devices in the past and am familiar with their operation. I assume the disk explains how to use it. these devices if used as instructed are very effective in teaching you how to relax and they are very effective.

I suggest going to their website to get the answer to this question. You can probably find the manual online. I have no problem using it as a battery powered device.

I can't directly answer your question but I can tell you that it is equipped with a mini USB connector, both for charging the device and for connection to a device to be powered by it.

It is not battery powered it is mains AC ,I connect it via USB to to the 10w USB power adaptor that I use for my I- pad2. The adaptor is 100-240v - 0.45A. output of adaptor -5.1v @ 2.1A , this works very well. I have also connected it to my Acer notebook via USB and that also works very well (the USB connecting lead and a power adaptor are included with the scanner as a standard accessory).....hope this helps.

Hi Perry, It is not battery powered. It has a 110v-12v power supply with a cord that is 4 feet in length.

It is only powered via the USB under its dust cap. It must be plugged into a usb port for power.
