Each cartridge may comprise a heating element, a chimney contact connector located at a first end of the cartridge, a distal contact connector located at a second end of the cartridge, and one or more electrical connections between the heating element, the chimney contact connector, and the distal contact connector. ## Claims ### Claim 1 A vaporizer cartridge comprising: a housing extending from a first end to a second end; a heating element contained within the second end of the housing; a chimney within the housing and extending from the first end of the housing to the second end of the housing; a chimney contact connector located at a first end of the vaporizer cartridge; a distal contact connector located at a second end of the vaporizer cartridge; and one or more wires electrically connecting the chimney contact connector, the heating element, and the distal contact connector, wherein one of the one or more wires is located within the chimney and electrically connects the heating element to the chimney contact connector. ### Claim 2 (depends on 1) The vaporizer cartridge of claim 1 wherein the heating element is a heating coil. ### Claim 3 (depends on 1) The vaporizer cartridge of claim 1 further comprising a wick housing disposed between the chimney and the heating element. ### Claim 4 (depends on 3) The vaporizer cartridge of claim 3 wherein the wick housing has wick apertures, the chimney has chimney apertures, and the wick apertures are aligned with the chimney apertures. ### Claim 5 A portable vaporizer comprising: a power source, a first cartridge having a first heater electrically connected to the power source; a mouthpiece; and a set of one or more cartridges having a second heater, the set of one or more cartridges removably attached in series between the first cartridge and the mouthpiece, wherein the second heater of the set of one or more cartridges is electrically connected in series to the power source through the first heater of the first cartridge. ### Claim 6 (depends on 5) The portable vaporizer of claim 5 wherein the first cartridge comprises a primary cartridge, the primary cartridge contains a first vaporizing fluid, and one of the set of one or more cartridges contains a second vaporizing fluid. ### Claim 7 (depends on 6) The portable vaporizer of claim 6 wherein the set of one or more cartridges comprises at least one secondary cartridge. ### Claim 8 (depends on 6) The portable vaporizer of claim 6 wherein the set of one or more cartridges comprises at least a first secondary cartridge and a second secondary cartridge. ### Claim 9 (depends on 6) The portable vaporizer of claim 6 wherein the set of one or more cartridges comprises at least a first secondary cartridge, a second secondary cartridge, and a third secondary cartridge. ### Claim 10 (depends on 6) The portable vaporizer of claim 6 wherein the primary cartridge contains a vaporizing liquid that contains nicotine. ### Claim 11 (depends on 7) The portable vaporizer of claim 7 wherein a first secondary cartridge within the set of one or more cartridges contains a vaporizing liquid that contain terpenes. ### Claim 12 (depends on 7) The portable vaporizer of claim 7 wherein a first secondary cartridge within the set of one or more cartridges contains a vaporizing liquid that contain essential oils. ### Claim 13 (depends on 6) The portable vaporizer of claim 6 wherein the primary cartridge contains a vaporizing liquid that contains a cannabis-based substance. ### Claim 14 (depends on 10) The portable vaporizer of claim 10 wherein a first secondary cartridge within the set of one or more cartridges contains a vaporizing liquid that contain terpenes. ### Claim 15 (depends on 10) The portable vaporizer of claim 10 wherein a first secondary cartridge within the set of one or more cartridges contains a vaporizing liquid that contain essential oils. ### Claim 16 (depends on 13) The portable vaporizer of claim 13 wherein a first secondary cartridge within the set of one or more cartridges contains a vaporizing liquid that contain terpenes. ### Claim 17 (depends on 13) The portable vaporizer of claim 13 wherein a first secondary cartridge within the set of one or more cartridges contains a vaporizing liquid that contain essential oils. ### Claim 18 A portable vaporizer comprising: a power source; a first cartridge electrically connected to the power source and comprising: a first housing extending from a first end to a second end; a first heating element contained within the second end of the first housing; a first chimney within the first housing and extending from the first end of the housing to the second end of the housing; a first chimney contact connector located at a first end of the first cartridge; and a first distal contact connector located at a second end of the first cartridge; wherein the first-chimney contact connector, the first heating element, and the first distal contact connector electrically connect, by one or more wires residing in the chimney, the first end of the first cartridge to the second end of the first cartridge; a removable second cartridge electrically connected to the first cartridge and comprising: a second housing extending from a first end to a second end; a second heating element contained within the second end of the second housing; a second chimney within the second housing and extending from the first end of the second housing to the second end of the second housing; a second chimney contact connector located at a first end of the second cartridge; and a second distal contact connector located at a second end of second cartridge; wherein the second chimney contact connector, the second heating element, and the second distal contact connector electrically connect, by one or more wires residing in the chimney, the first end of the second cartridge to the second end of the second cartridge; and wherein the first chimney contact connector is configured to contact the second distal contact connector thereby electrically connecting in series the second cartridge to the power source. ### Claim 19 (depends on 18) The portable vaporizer of claim 18 wherein the first cartridge contains a first vaporizing fluid and wherein the second cartridge contains a second vaporizing fluid. ### Claim 20 (depends on 19) The portable vaporizer of claim 19 wherein the first cartridge contains a vaporizing liquid that comprises nicotine.
