Working voltage: 3.7V

Static Current: <=5uA

Charger protection:

If the voltage is higher than 4.28v,The charging circuit will cut off to protect the berrery,

When the voltage is get 4.18v, The chargers will be suitable to the battery,If the charger and the E-cigarette connect sucessfully,the LED will shine 4 times.

Smoking protection:

When you smoke,the LED will gradually light and out.Meanwhile,the atomizer will be hot and produce some fog, one monthful  of the smoking  last more than 5 seconds,the LED continuous to shine 2 times.

Cleaning of the atomizer:

full battery can vapor keep for 300 mouthfuls,the LED will be lighting all the time and the heating wire will be cleaned 3 seconds Protection of the heating wire's short-circuit: if the internal resistance is lower than 2 OMEGA,when you smoke, The LED will be lighting on for 2 seconds,that is  the "protection of Short-circuit ".

Detect of the Voltage:

When the Voltage is lower than 3.0V,The circuit will alarm;If the atomizer doesn't produce fog and the LED continues to shine 20 times before you smoke, It's a sign that the voltage is too low,you should check the Voltage.
