An electronic cigarette, including: an atomizer assembly, a battery assembly, and a charger assembly. The atomizer assembly includes: a temperature sensing wire, a first steel tube configured to receive the temperature sensing wire, and a temperature sensing base. The battery assembly includes an adjustment wheel. The charger assembly includes two elastic contact pins. The atomizer assembly is in threaded connection with the battery assembly. The battery assembly is disposed on the charger assembly. The charger assembly is electrically connected to the battery assembly via the two elastic contact pins so as to charge the battery assembly. The temperature sensing wire transmits temperature parameters to the battery assembly, and a power output is adjusted by the adjustment wheel thereby realizing temperature control.
