Abstract: A cordless handheld steamer comprising an interior chamber containing a steam generation unit and a water reservoir. The water reservoir generally encompasses the steam generation unit and the steam generation unit contains a heating element. A precise temperature control unit monitors the heating element's temperature to maintain an optimum steam producing temperature without overheating. The heating element is powered only by an on-board battery pack. A user determined amount of water is pumped from the water reservoir to the flash boiler chamber where the water is converted to steam and the steam travels through a plenum to a target area.
