Abstract: The e-vaping cartridge includes a housing body with a first tube extending longitudinally within the housing body and defining a central passage, the first tube further defining at least one first hole. One or more layers of absorbent material are positioned within an inner annulus reservoir around at least a portion of the first tube. A wick is in communication with the central passage where distal ends of the wick traverse the first hole and is in communication with an annulus reservoir. A heater is configured to vaporize a pre-vapor formulation communicated to the wick from the annulus reservoir. The e-vaping device includes the cartridge which is connectable to a power section.
