1. An e-vaping device, comprising:
a cartridge, the cartridge including
a housing including first and second ends;
at least first and second reservoirs positioned within the housing between the first and second ends, the first and second reservoirs being configured to hold respective first and second pre-vapor formulations; and
at least first and second vaporizer assemblies positioned within the housing on opposite ends of the first and second reservoirs, the first vaporizer assembly being coupled to the first reservoir, the first vaporizer assembly being configured to vaporize the first pre-vapor formulation to generate a first vapor closer to the first end than the second end, the second vaporizer assembly being coupled to the second reservoir, the second vaporizer assembly being configured to vaporize the second pre-vapor formulation to generate a second vapor closer to the second end than the first end; and
a power supply section configured to selectively supply power to the first and second vaporizer assemblies, wherein the power supply section includes control circuitry, the control circuitry being configured to independently control vapor generation by the first and second vaporizer assemblies.
