You can plug it in and you have the option to use batteries. I had mine for almost a year and never put a battery in it.

This item doesn't have an internal battery. It has to be plugged in during operation.

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

Its not battery operated if that's what you are asking. You have to plug it in to use it.

I believe it says so in the instructions, either plug-in or battery operated.

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

No batteries required. It is powered through the pins via whatever you dock it too, much like docking your phone/iPod.

No, it does not require batteries. Just plug it in. It has a nice storage area for the cord underneath also.

No batteries at all. Plug in only. I LOVE this mirror. In fact, I am on my second one. The first one I had for probably 7 years and then the light died. I couldn't find it in stores, so I had to get online to find it. It's a great mirror. You'll be very pleased!!

No batteries are needed. It gets what little power it needs from the USB port

There is no battery with this machine. It has to remain plugged in to be used. Think of this as a desktop machine, not a laptop or tablet.
