a heater coil housing forming a heater coil chamber; the heater coil housing having a base and a pair of sidewalls, the base having an air inlet; first and second notches between the pair of sidewalls; a heater coil wrapped around a wick; the wick extending through the notches into a recessed pocket between the heater coil housing and a media storage tank wall; the wick perpendicular to a longitudinal axis of the cartomizer; electrical contacts extending through the base and electrically connected to the heater coil; the heater coil housing having an outlet connected to an axial cylindrical neck; a first end of an inner tube inserted into the axial cylindrical neck; a second end of the inner tube inserted to a proximal seal; a chamber between the proximal seal and a mouth piece; an absorbent material in the chamber; and the mouthpiece having one or more outlets. ### Claim 2 (depends on 1) The cartomizer of claim 1 wherein a first end of the cartomizer is adapted to be inserted into a battery assembly. ### Claim 3 (depends on 2) The cartomizer of claim 2 wherein the first end of the cartomizer is adapted to connect to a battery assembly via a friction fit. ### Claim 4 (depends on 1) The cartomizer of claim 1 wherein portions of the wick are compressed by ports in the heater coil housing, the ports having an opening less than a diameter of the wick. ### Claim 5 (depends on 1) The cartomizer of claim 1 wherein the recessed pocket is configured to retain liquid by surface tension. ### Claim 6 (depends on 1) The cartomizer of claim 1 further comprising a cover on the first end of the cartomizer to protect connectors on the cartomizer. ### Claim 7 (depends on 1) The cartomizer of claim 1 wherein the absorbent material is a porous material 0.1-6 mm thick. ### Claim 8 (depends on 1) The cartomizer of claim 1 wherein the absorbent material comprises a porous plastic material. ### Claim 9 (depends on 1) The cartomizer of claim 1 wherein the inner tube and the heater coil housing are connected by an interference fit. ### Claim 10 (depends on 1) The cartomizer of claim 1 wherein the mouth piece is attached to the liquid storage tank with a snap fit. ### Claim 11 (depends on 1) The cartomizer of claim 1 having two air inlets. ### Claim 12 (depends on 1) The cartomizer of claim 1 wherein the absorbent material comprises cotton. ### Claim 13 A cartomizer for use with an electronic smoking device, comprising: a liquid media storage tank; a heater coil chamber formed by a heater coil housing; the heater coil housing having a base and a pair of sidewalls; an air inlet in the base; first and second notches between the pair of sidewalls; a heater coil wrapped around a wick; the wick extending through the notches into a recessed pocket between the heater coil housing and a media storage tank wall; the wick perpendicular to the longitudinal axis of the cartomizer; electrical contacts extending through the base and connected to the heater coil; the heater coil housing having an outlet connected to an axial cylindrical neck; an inner tube inserted into the axial cylindrical neck; the inner tube inserted to a proximal seal; an expansion chamber between the proximal seal and a mouth piece; two absorbent material pieces in the expansion chamber; the mouthpiece having one or more outlets; and the mouthpiece attached to the cartomizer via a snap fit. ### Claim 14 (depends on 13) The cartomizer of claim 13 wherein a first end of the cartomizer is adapted to be inserted into a battery assembly. ### Claim 15 (depends on 13) The cartomizer of claim 13 wherein portions of the wick are compressed by ports in the heater coil housing having an opening less than a diameter of the wick. ### Claim 16 (depends on 13) The cartomizer of claim 13 wherein the recessed pocket is configured to retain liquid by surface tension. ### Claim 17 (depends on 13) The cartomizer of claim 13 further comprising a cover on the first end of the cartomizer to protect connectors on the cartomizer. ### Claim 18 (depends on 13) The cartomizer of claim 13 wherein the absorbent material is a porous material 0.1-6 mm thick. ### Claim 19 (depends on 13) The cartomizer of claim 13 wherein the absorbent material comprises cotton. ### Claim 20 (depends on 13) The cartomizer of claim 13 wherein the absorbent material comprises a porous plastic material. ### Claim 21 (depends on 13) The cartomizer of claim 13 wherein the inner tube and the heater coil housing are connected by an interference fit. ### Claim 22 (depends on 13) The cartomizer of claim 13 having two air inlets. ### Claim 23 A cartomizer for use with an electronic smoking device, comprising: a liquid media storage tank; a heater coil chamber formed by a heater coil housing; the heater coil housing having a base and a pair of sidewalls; an air inlet in the base; first and second notches between the pair of sidewalls; a heater coil wrapped around a wick; the wick extending through the notches into a recessed pocket between the heater coil housing and a media storage tank wall; the wick perpendicular to the longitudinal axis of the cartomizer; electrical contacts extending through the base and connected to the heater coil; the heater coil housing having an outlet connected to an axial cylindrical neck; an inner tube inserted into the axial cylindrical neck of the heater coil housing; the inner tube connected to the heater coil housing by an interference fit; the inner tube inserted to a proximal seal; an expansion chamber between the proximal seal and a mouth piece; an absorbent material in the expansion chamber, the absorbent material comprising a porous material 0.1-6 mm thick; the mouthpiece having one or more outlets; the mouthpiece attached to the cartomizer via a snap fit; and a cover on the first end of the cartomizer to protect connectors on the cartomizer. ### Claim 24 (depends on 23) The cartomizer of claim 23 wherein a first end of the cartomizer is adapted to be inserted into a battery assembly. ### Claim 25 (depends on 24) The cartomizer of claim 24 wherein the first end of the cartomizer is adapted to connect to a battery assembly via a friction fit. ### Claim 26 (depends on 23) The cartomizer of claim 23 wherein portions of the wick are compressed by ports in the heater coil housing, the ports having an opening less than a diameter of the wick. ### Claim 27 (depends on 23) The cartomizer of claim 23 wherein the recessed pocket is configured to retain liquid by surface tension. ### Claim 28 (depends on 23) The cartomizer of claim 23 wherein the mouth piece is attached to the liquid storage tank with a snap fit. ### Claim 29 (depends on 23) The cartomizer of claim 23 having two air inlets. ### Claim 30 (depends on 23) The cartomizer of claim 23 wherein the porous material comprises cotton.
