No. This is a wired mouse (not a wireless one). I highly recommend it if you are spending more than few hours in front of the screen or have issues/pain with wrist

No! It uses batteries. And a lot of them too. The batteries go dead very quick!

It must be plugged in. It doesn't have a battery because it uses too much power for a battery.

It came ready to use. It did not require batteries. Whether there is an existing battery that may run out at some point, that I am not sure about. All I know is that it did not require batteries right out of the box. It has provided hours of music and if pun for our granddaughter.

No. It needs to be plugged in since there is no battery pack on the controller.

It definitely is powered by a battery but I do not recall if it came with one. I seem to think it requires a 9v. Sorry that I could not be sure.

It does not come with a battery, you will need to buy one or use one from another tools you may have.

No, you don't need batteries at all. If you haven't had enough sun for it to be charged thru the solar panel, just crank it a few seconds. It doesn't take much. I love it. It's very small size makes it so cute, yet it's very functional. You can't really tell by the picture the size of it, but the dimensions are in the description. And to give you an idea, it has a wrist strap.

It does come with a battery. If you plan to use it for extended periods of time, you may want to buy a spare.

It does, but it uses very little energy. I have not changed batteries since purchase.

No this does not need a battery. It is plugged into the wall. Also, the only way to turn it off is to unplug it.

No, but the item is good enough to let it run on batteries. You can buy rechargeable batteries with a charger, a good idea.
