A nebulizer includes an aerosolizer, a controller, a power converter, a power source and a voltage detector. When the aerosolizer is requested to eject aerosolized liquid at a standard spraying speed, the controller sets a parameter value of a conversion parameter based on a stored standard value, transmits the parameter value to the power converter, and controls the power source to supply electric power. The power converter converts the electric power based on the parameter value to power the aerosolizer. Based on a stored expected value and a detected value generated by the voltage detector in response to operation of the aerosolizer, the controller controls the power source to adjust the voltage of the electric power supplied thereby.
