This disclosure relates to a portable ionizer worn in the vicinity of the human face, including, for example, a necklace to diffuse concentrations of negative ions in the facial area of the wearer where the ions are beneficial. As a consequence of this capacity to focus the ion flux, fewer ions must be produced by the source to obtain the benefit to the wearer because of a greater local concentration. The necklace ionizer is given a pleasing external appearance and a useful purpose, such as an advertising display. The negative ions are generated by a high-voltage alternate frequency ion generating needle. A control module including a power management system, a transformer, and a multiplier is used to minimize power drain on a rechargeable battery. Other features of the power management system include an LED display shut-off, battery voltage cut-off, management of needle life, and management of power supply drain time through frequency modulation or voltage control.
