A power optimization electronic cigarette device is configured to be reusable for a limited number of refills through use of an easily accessible liquid refilling structure, before ultimately becoming disposable. The electronic cigarette device takes advantage of multiple heating wires that can be selectively operated to vaporize the liquid solution. The selective use of one heating wire, from two or more heating wires serves to extend the life span thereof. A sensor detects the air flow generated from inhaling through the electronic cigarette and triggers the heating wires to generate heat while the electronic cigarette is in use. In another power optimization function, the electronic cigarette device comprises a circuit board that detects available power in a battery, and an illumination member that variably illuminates to indicate remaining battery power. The electronic cigarette also provides a USB charging port for recharging the battery.
