How much electricity is my AC unit using when it's on "fan"?

Does my window air conditioner use just as much electricity on the "fan" setting as it does on the "cool" setting?

On cooler days this time of year, I often turn my window AC unit to the "fan" setting to pull in some of that cool air from outside. I have always assumed that if the unit is functioning as a fan, it's not using nearly as much electricity as when I've got it set to "cool." Is that an incorrect assumption? And if it does use less power than when it is cooling, how much less? Is it a negligible difference or is it substantial? Would it be better to just stick a box fan in a window?
