A battery powered nebulizer (10) includes a portable housing (58) containing a battery power supply (13), pump-motor combination (14), air compressor (16) and control circuitry (20). The control circuitry (20) includes a pulse width modulator (24) for switching power to the motor (14) to conserve battery charge and regulate the pump-motor combination (14) to a predetermined volume output. The nebulizer (10) includes a charger (40) for charging the battery (13) and an adapter (34) to be connected to an external battery supply. A monitor (46) monitors the charge on the battery (13) to audibly and visually indicate low battery charge.
