ABSTRACT:
A portable aerator may be operated utilizing either internal direct current power or external alternating or direct current power. The aerator includes a housing in which are mounted an aerator pump and a motor for driving the aerator pump. The motor is connected to positive and negative contacts, which are interengagable by one or more direct current batteries. A jack mounted to the housing is electrically connected to the contacts and the jack is operably interengagable with an external adapter that is selectively attached to an external alternating or direct current power supply for supplying external power to the contacts and thereby to the motor. A switch may be employed to selectively provide power to and disconnect power from the motor.
