The invention provides a control method of an electronic cigarette. The method comprises the following steps: S100, obtaining a resistance value of an atomization assembly (20), determining whether the atomization assembly (20) has a magnetic material (21), if so, displaying a first display interface, and otherwise, displaying a second display interface; S200, according to the obtained resistance value of the atomization assembly (20) and a preset corresponding table, outputting corresponding power; and S300, determining whether output power/voltages are adjusted, if a determining result is yes, recording the output power after adjustment, and re-generating a corresponding table, and if the determining result is no, ending operation. Further provided is an electronic cigarette using the control method. According to the invention, user operation can be simplified, and the electronic cigarette is better customized.
