Electronic smoking article

An electronic smoking article operable to produce an aerosol comprising:

• an outer housing extending in a longitudinal direction and including an upstream end;
• a liquid aerosol formulation;
• a heater operable to at least partially volatilize at least a portion of the liquid aerosol formulation and form an aerosol;
• a power supply operable to apply voltage across the heater;
• a charging button assembly including a conductive post that forms a first external, electrical contact at the upstream end of the electronic smoking article, the charging button assembly operable to be pushed so as to illuminate at least one light emitting diode (LED);
• and
• a second external, electrical contact at an outer surface portion of the outer housing adjacent the upstream end of the electronic smoking article.

A method of charging an electronic smoking article, the method comprising:

• inserting at least a portion of an electronic smoking article into a charger including a well, a first electrical contact and a second electrical contact, the electronic smoking article including:
• an outer housing extending in a longitudinal direction and including an upstream end;
• a liquid aerosol formulation;
• a heater operable to at least partially volatilize at least a portion of the liquid aerosol formulation and form an aerosol;
• a power supply operable to apply voltage across the heater;
• a charging button assembly including a conductive post that forms a first external, electrical contact at the upstream end of the electronic smoking article, the charging button assembly operable to be pushed so as to illuminate at least one light emitting diode (LED);
• and
• a second external, electrical contact at an outer surface portion of the outer housing adjacent the upstream end of the electronic smoking article,
• wherein the first electrical contact of the charger contacts the conductive post of the electronic smoking article during charging and the second electrical contact of the charger contacts the second, external, electrical contact of the electronic smoking article so as to form an electrical connection between the charger and the electronic smoking article and charge the electronic smoking article.
