no. But I have mine plugged in beside my chair. Just turn it on when needed. I have never put batteries in. If you travel you might want the battery option.

No. It plugs in. But I don't recommend this warmer. I had 2 and they both broke.

Electric. Plug it in. I don't think batteries would ever give enough power.

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

No it isn't, you have to plug it in. Having a plug allows it to be a little more powerful than it would be if it ran on batteries.

It doesn't require batteries. It must be plugged into an electrical outlet.

It plugs in. No Batteries. This unit works well for me. I have nerve damage in my neck. I put a pillow behind my back, Put this unit around my neck, In this way I can move my head back or forward to control the depth of the massage

I believe you have to plug it in. I don't see any place where batteries can be put in. I always plug it in.

It plugs in...you will have to run an extension cord. Luckily, I have a separate room with the toilet in it and there is a plug in there.

You can plug it in (plug included in package). It's a better option than batteries because the battery compartment is annoying to open.
