1. An electronic vaping device comprising:
a first cartridge including,
a vaporizer assembly configured to produce a vapor, the vaporizer assembly including,
a first tank configured to store a pre-vapor formulation,
a tube extending from an outlet of the first tank and configured to direct the pre-vapor formulation from the first tank to a mixing chamber, the tube including an inlet fluidly coupled to the outlet of the first tank and an outlet fluidly coupled to the mixing chamber, and
a heater configured to heat the pre-vapor formulation and form a vapor;
a second cartridge, the first and second cartridges configured to generate different dispersions, the second cartridge including,
an atomizer assembly configured to produce an aerosol, the atomizer assembly including,
a second tank having a flexible wall and configured to store a pre-aerosol formulation,
an atomizer configured to atomize the pre-aerosol formulation and form the aerosol without heating the pre-aerosol formulation,
a carbon dioxide capsule configured to apply pressure to the pre-aerosol formulation, and
a dual piston cylinder between the second tank and the carbon dioxide capsule, the dual piston cylinder including two pistons with a spring connected therebetween, the dual piston cylinder configured to at least partially reduce the pressure applied from the carbon dioxide capsule on the second tank;
a second section including a power supply configured to supply power to the heater; and
a cartridge holder extending a width of the electronic vaping device and having a first slot configured to receive the first cartridge and a second slot configured to receive the second cartridge, the first cartridge configured to fill a first diameter of the first slot and the second cartridge configured to fill a second diameter of the second slot.
