Abstract
A charging device includes a charging assembly for imparting a charge on a mobile device, a housing for receiving the mobile device to be charged, and for defining a cavity therein for housing the charging assembly. There is at least one air intake port in the housing for allowing air to be drawn into the cavity and at least one air exhaust port in the housing for allowing air to be exhausted from the cavity. There is an ionic wind generator, for generating an airstream to draw air into the housing through the at least one air intake port, through the cavity, and push air out of the housing through the at least one air exhaust port. The ionic wind generator comprises an emitter and a collector, such that when a voltage is applied to the emitter, air ionizes around the emitter and is drawn toward the collector, thereby creating the airstream.
