It uses a standard wall outlet. It has a DC power supply similar to that of most laptops or printers, etc:Package included: * 1 x 2 Port HDMI Splitter * 1 x DC Power Supply * 1 X User Manual

It has a plug. It also has the ability to run on batteries, but I don't know how long the charge would be since I keep it plugged in.

It's a plug in! Which i like because it's brighter than ones i've used that are batteries. But caution, it does get a little warm/kinda hot to the touch if left on a long time. Other than that, i love the heck out of this!

Yes, it has to be plugged in. It does not come with a battery adapter. I had an outlet on my porch within reach, but most people probably need to use an extension cord.

It plugs in to the wall using an AV adapter. I believe you can use batteries as well. DDs I think.

No, you don't need to plug it in, it comes with a battery, that is how the light is on.

you have to plug it into a usb or get an adapter plug to plug in outlet. They are built in batteries.

Yes it works plugged in. I have never picked it up and found the battery dead. While using, if the battery needs charging, a red light comes on to indicate it needs charging. So when I am done using it, I plug it in. I have not yet had it die while using. Good battery life.

It doesn't say anything about a power cord to plug it in... just that there's no batteries. Does it plug into a regular outlet?

It is USB and battery powered. It plugs into your USB port but the base of the unit (where the "on" switch is), has two AA batteries.

Plugs in and takes batteries. I guess you could use rechargeable batteries, but unit will not charge them.

You plug it in. You turn it on. Most plugs from what I remember are AC. Strange question.

Yes, it plugs in. I got it for my Dr I work for to have in his office and he loves it! Just make sure to turn it off once it's done to avoid overheating it.

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