Um, are you asking about the power adapter that you might take off the 9V
train regulator, for example? My expectation is that this item being
discounted is the brick only, and the brick takes in power at its input plug
but does not come with a walllwart.
(I ordered 5 of these because I do plan to use them with wallwarts that I
will be getting elsewhere...)
