A "wall-wart" is a small
transformer that converts AC power to DC or some other form of AC.
Digital-diy.com
is now my favorite website for in depth information on every type of
wall transformer and power supply you could imagine. It's open source
electronics that can save you a lot of time when making decisions on
the amount of voltage and amperage you might end up choosing for your
latest contraption of the day.
