Oopsie! Still workin' on my coffee . . . xx(

Model No: M5651 (APS-20U) = DC 7.5V x 2.0A = 15W

How to convert amps to watts shuckled into the format intended:

V(V) x I(A) = P(W)

. . . still working on the coffee, but something doesn't quite add up:

Macintosh Portable Power Adapter = Model No: M5163 (SMP-10BB) = 7.5V x 1.5A = 11.5W :O

Is the 15W adapter for the Backlit Portable? :?: Mine's the original Luggable and the adapter's not even listed in the Apple table on mcd's link.
