Sorry when I answered your ? I meant to add that the 2 AA batteries are NOT included. I figured you knew that, since you asked what size it needed.

It takes 3 AA batteries but you can also use an AC adapter. It doesn't come with one but it gives you the specifics of what kind to buy in the instructions.

It uses 4 batteries. I've been using mine for 2 months and the batteries are still going strong. You may only have to replace them twice a year.
