Abstract: A vaporization device including a housing, a plurality of wicks, a plurality of heating elements and a power control circuit. The plurality of wicks are at least partially contained within the housing and include a first wick and a second wick. The plurality of heating elements include a first heating element and a second heating element. The first heating element is proximate to the first wick and the second heating element is proximate to the second wick. The power control circuit powers the first heating element at a first level when the second heating element is not powered. The power control circuit powers the first heating element at a second level when the second heating element is powered.

Abstract: The present invention provides a vapor generator for evaporating a volatile substance into the atmosphere. The vapor generator includes a heat source, a reservoir, and a wick. In one aspect of the invention, the vapor generator output is adjustable by rotating the reservoir. In another aspect of the invention, a visual indicator indicates the relative output setting of the vapor generator. In another aspect of the invention, the reservoir is mounted relative to the heat source by magnetic attraction.
