a heating element;
an atomizing chamber;
a reservoir for holding free-flowing source liquid;
a porous wick extending from the atomizing chamber to the reservoir and comprising a heater portion in cooperation with the heating element within the atomizing chamber such that the heating element is external to the heater portion or disposed within the heater portion, and at least one liquid collecting portion within the reservoir, the at least one liquid collecting portion having a maximum cross-sectional area that is greater than a cross-sectional area of the heater portion,
wherein the heating element is formed as a wire and the porous wick is formed from a porous non-fiber-based material with integral interstitial pores.
