Does this use batteries or does it plug in?

It plugs into the wall outlet. Low output good for 5 gallons or less. I needed two for my ten gallon but cheap enough that it did not matter to me.

This plugs in - which I prefer so you can set it on a timer. I'm using it on a Picotope 3 gallon and it is the perfect size.

I has a two-prong plug. There is an on/off switch on the side of the lamp below where it attaches to the side of the tank/bowl.

No, you plug it into a power outlet to get it charged. No batteries needed.

It runs on batteries. You can plug in a 12V power source of your choosing. I use a universal power adapter that came with several plugs and found one that fits nicely.

No batteries, you have to plug it in. It does work, beautifully, and so energy efficient.

Yes, if you mean, does it plug into a wall socket. It doesn't run on batteries.

It doesn't use batteries. It gets its power from the USB connection on the laptop or computer.

No batteries, or plugs. It uses the heat from the top of your wood stove to operate.

It doesn't take batteries. You plug it in - either in the USB port in a computer or else in the regular outlet in the wall - you can do either one.

NO! Although it pops up in search for battery operated lights, it plugs in. Yet another in the myriad Amazon search fails.

It only works by being plugged into an outlet. It is not made for batteries.

Does not use batteries, you have to have it plugged into the electric outlet all the time.

No batteries: it plugs in. First one only lasted about 10 years; was still working, butgrips wore out. Can't imagine being without it. Does not go camping in the woods!Bashful3

It has to be plugged in to work. No batteries, but has an on/off button. I have it sitting on top of some files in the lower part of my desk as it doesn't really radiate a lot of heat unless it's close to you. I like it though.

I really don't know as I don't use batteries, I just plug it in when I need it.
