When the heating element installed at the base of the machine receives a voltage of about 220V, the super kettle will start working. At this time, the electricity from the power source will supply energy to the heating plate and then convert it into heat energy.

All this heat will be transferred directly to the water, thereby heating the water & boiling water in just a few minutes. The boiling time of a super kettle will depend on 2 main factors: kettle capacity & capacity. The larger the capacity, the faster the boiling time will be, usually the boiling time will fluctuate between 3-7 minutes.

When the temperature in the water reaches the required boiling point, the steam that rises will pass through the duct and blow the hot steam into the heater. At this time, the heat rod will bend up & act on the switch. The switch of the kettle will automatically turn off and disconnect the heat source connected to the kettle to ensure optimal safety during use.

If the kettle switch is off, it means the water has been boiled, within a period of 20-30 seconds the user will not be able to turn the kettle back on. Because at this moment the heat bar is still hot & cannot return to its original state.
