An aerosol delivery device includes a housing and a reservoir having an open end and an opposing closed end. The reservoir includes an aerosol precursor composition therein. The aerosol delivery device also includes an electrical contact in or on the housing. The device further includes a vaporizing unit. The vaporizing unit includes a liquid transport element, a heating element, and an electrical connector. The vaporizing unit is configured to removably engage the open end of the reservoir such that the liquid transport element is in arrangement with the reservoir to transfer the aerosol precursor composition from the reservoir to the heating element and configured to engage the electrical contact in or on the housing.
