         4 . The personal vaporizer of  claim 3 , wherein the user input device includes a slider configured to move between a first position corresponding to selection of the first operating mode, a second position corresponding to selection of the second operating mode, and a third position corresponding to selection of the third operating mode. 
     
     
         5 . The personal vaporizer of  claim 3 , wherein the housing further comprises an electronics system configured to control the delivery of power from the power source to one or more of the receiving ports based on a selected operating mode, the electronics system comprising first and second airflow sensors configured to detect airflow through the first and second cartridges, respectively. 
     
     
         6 . The personal vaporizer of  claim 5 , wherein the electronics system selectively activates the airflow sensors based on the selected operating mode. 
     
     
         7 . The personal vaporizer of  claim 1 , further comprising a mouthpiece configured to receive a top end of each of the first and second cartridges, wherein a bottom end of each cartridge is disposed within the housing. 
     
     
         8 . The personal vaporizer of  claim 7 , wherein the mouthpiece comprises a first airway for delivering a vapor produced by the first cartridge and a second airway for delivering a vapor produced by the second cartridge. 
     
     
         9 . The personal vaporizer of  claim 1 , wherein the first and second receiving ports are located substantially side by side at a top end of the housing. 
     
     
         10 . The personal vaporizer of  claim 1 , further comprising a charging port and a movable component coupled to the housing and configured to move between a first position configured to cover the charging port and a second position configured to expose the charging port. 
     
     
         11 . A method of delivering one or more vaporized substances using a personal vaporizer comprising a power source coupled to a first cartridge and a second cartridge, the method comprising:
 receiving, via a user input device, user selection of one of a plurality of operating modes, the operating modes comprising a first operating mode for enabling operation of the first cartridge only, a second operating mode for enabling operation of the second cartridge only, and a third operating mode for enabling simultaneous operation of both cartridges; and   activating one or more of the cartridges based on the selected operating mode.   
     
     
         12 . The method of  claim 11 , wherein activating one or more of the cartridges comprises:
 activating each airflow sensor coupled to said one or more cartridges, and upon detecting airflow at said sensors, delivering power from the power source to the one or more cartridges.   
     
     
         13 . The method of  claim 12 , wherein delivering power to the one or more cartridges causes activation of a heating element included in each of the one or more cartridges, the heating element being configured to heat a substance disposed in the cartridge into a vapor. 
     
     
         14 . A vaping system, comprising:
 a first cartridge comprising a first substance to be vaporized;   a second cartridge comprising a second substance to be vaporized, the second substance being different from the first substance;   a housing configured to receive the first and second cartridges; and   a power source disposed within the housing and configured to selectively deliver power to the first and second cartridges.   
     
     
         15 . The vaping system of  claim 14 , further comprising an electronics module disposed within the housing and electrically coupled to the power source and each of the cartridges, the electronics module being configured to selectively control operation of the first and second cartridges based on a user input. 
     
     
         16 . The vaping system of  claim 15 , further comprising a user input device coupled to the electronics module and configured to enable user selection of one of the following: (1) a first operating mode for activating only the first cartridge, (2) a second operating mode for activating only the second cartridge, and (3) a third operating mode for simultaneously activating both cartridges. 
     
     
         17 . The vaping system of  claim 16 , wherein the electronics module is configured to control delivery of power from the power source to one or more of the cartridges based on a selected one of the operating modes. 
     
     
         18 . The vaping system of  claim 17 , wherein the electronics module comprises first and second airflow sensors configured to detect airflow through the first and second cartridges, respectively, the electronics module being further configured to:
 identify the airflow sensor corresponding to each cartridge being activated by the selected operating mode,   activate each identified airflow sensor, and   upon detecting airflow at said sensor or sensors, deliver power to the corresponding cartridge or cartridges.   
     
     
         19 . The vaping system of  claim 18 , wherein each cartridge includes a heating element for heating the respective substance into a vapor, the heating element being activated upon receiving power from the power source. 
     
     
         20 . The vaping system of  claim 14 , further comprising a mouthpiece configured to receive a top end of each of the first and second cartridges, wherein a bottom end of each cartridge is disposed within the housing.
