It's only battery operated. Mine hasn't worked right from the beginning. I would not recommend this product. Hope this helps.

It does not use batteries. It plugs into any standard 120 volt wall outlet.

It uses both a plug and batteries. I have only used it with the plug which would be your best bet. But if you used batteries it reqires 4 AA.

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

It charges the phone and I have only ever used it through AC outlet but I believe it does not have the option to use it on batteries.

Yeah! So I've plugged mine in for a power source, but it takes batteries.However, it doesn't have a speaker/amp so you'd need to orchestrate a way to do that

This device has a battery so you don't have to keep the power plugged in. Still though I wouldn't recommend this product.

It comes with a its own power supply that must be plugged in. While it would be possible to power it from batteries I don't think it would be practical, it would drain them pretty quickly.

Yes it uses batteries or you can plug it in (if you get all that come with it.) see the other reviews. I was apparently lucky to get both lol

I believe I answered this once. The item you mention does not have a power adapter and does not work well with one. Plugging in a powere adapter seems to interrupt the output. It is strictly a portable battery powered device. Deric

It is battery operated with no usb power option. It uses AA batteries. I bought it to use with cheap headphones and my tablet on planes. It works great for that, plenty of volume, 3 ports for others to watch with you and the batteries last much longer than I expected them to.

Its like any other battery power device. It will last as long as the batteries. This one is plugged in (that's how it recharge) but it will last a little while on the battery. Can't tell how long exactly though. Not sure why you need battery only but that's definitely a high-end video monitor, i don't think it will last very long without a power outlet.

It needs to be plugged into the wall socket at all times. No battery operated function.

Hi Beth, This device has no battery. You need to connect it to a power source. -Anthony

Yes, you need to plug it in to an electrical outlet. OR you can also put batteries in it to make it portable. Either way, the transmitter needs a power source.

It comes with an adapter to plug into 120vac wall outlet. It also runs on 4-aa batteries if you want. I use the wall adapter so I don't know how long the batteries would last.

Yes, it plugs into an outlet, however it does not have a rechargeable battery it has to be plugged in to use, but it does take size D batteries if you want to do it that way.
