An aerosol delivery device having a check valve therein for use with refilling the aerosol delivery device is provided. The aerosol delivery device may comprise at least one housing defining a refillable reservoir for storing an aerosol precursor composition, and a heating element contained within the at least one housing and configured to activate and vaporize components of the aerosol precursor composition. A connector may be coupled to the at least one housing and sealably connectable with a container of aerosol precursor composition for refilling the reservoir. The connector may include a check valve configured to enable only a one-way flow of aerosol precursor composition from the container into the reservoir when the connector is sealably connected with the container.
