Abstract
An external AC power adapter defines a power conversion chamber that retains power conversion circuitry operable to convert an input power to an output power. The power adapter further include an intake chamber and an outlet chamber, both having an aperture that places the respective chamber in fluid communication with the power conversion chamber. Each chamber may have at least one vent to the ambient environment such that an air mover is operable to circulate ambient air through the power conversion chamber. Each chamber may include a guard that deters liquid that has entered the respective chamber from flowing into the associated aperture.
