Does this require batteries or is it powered by the USB? Thanks!

i hesitated a bit after seeing reginald goodman's answer. mine was powered with the USB for the conversion operation (so is the much bigger one i bought elsewhere. batteries are not necessary), but i THINK i remember seeing a battery compartment because you can carry this thing around with you and the batteries may become necessary then.

No batteries on mine. No power cord, either. It connects to the computer with the USB and that's how it gets its power.

This is not powered by battery. It is powered by plugging it into an electrical outlet.

There are one cable USB to an -Mini USB (http://en.wikipedia.org/wiki/USB) in the packet. Its Powered by the USB, no need for extra power.

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 does not require batteries, but does have to be attached to a USB port. This company offers a different version which is what you are looking for.

It runs and charges off of usb power. You can use a usb ac adaptor and leave it on, but at some point the battery may get damaged always being plugged in.

Just USB powered but I haven't had any issues with it. Albeit, I only use it on rare occasions for work

It is powered by usb through your computer. No other power supply is needed.

this item is not powered by USB, it comes with it's own power cord. seen in images of the product.

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.

Don, sorry forgot to say I didn't have to put in battery, and I've looked to see if any opening for one, I don't see it. So I assume just usb is sufficient. Hope that helps.

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

USB keyboards supply their own power, so there is no need for batteries for them at all. The review that mentioned it also mentioned it needed a PS/2 connection, it does not (no modern keyboard does).

Does not operate on batteries. Needs to plug to wall outlet or power through the USB cable into the computer.

The one we had used batteries only, but they lasted a long time. It had the USB cord..

this product doesn't run on batteries. it plugs into the computer's usb port and gets its power from that source.
