An electrostatic spray device includes an electrostatic mixing chamber and an electrode pair in the electrostatic mixing chamber. The electrostatic mixing chamber receives an airflow that is driven by a fan of the electrostatic spray device. The electrostatic mixing chamber also receives a flow of fluid from a reservoir of the electrostatic spray device. The electrode pair is configured to apply electrostatic charge to droplets of the fluid suspended in the airflow. A voltage level of the electrostatic charge is adjustable responsive to a first DC output from a first DC convertor. A flow volume of the fluid from the reservoir is adjustable responsive to a second DC output from a second DC convertor. In some cases, a control unit of the electrostatic mixing device modifies the first or second DC outputs based on a target level of the voltage level or the flow volume.
