How powerful is the average rice cooker? How much electricity does cooking need?

The power of the early rice cooker was 400 watts, and the small one may be 300 watts. Do not rule out that there are more powerful rice cookers.

At present, the common power of (20 18) rice cookers is 860 watts, and the low power version is not excluded.

Examples of half-hour power consumption of several electric rice cookers are provided for your reference:

300 watts: 0. 15 degrees for half an hour.

400 Watts: 0.2 kWh for half an hour.

600 Watts: 0.3 kWh for half an hour.

860 Watts: 0.43 kWh for half an hour.

Note: According to the above, it can be inferred that the power consumption of the rice cooker for half an hour can be calculated as 0.5 ‰ of the power.

Supplement: The heating of the rice cooker is discontinuous. When cooking, the chassis temperature will rise after the water is absorbed by the rice. When it reaches the temperature, it will cut off the power supply and keep the heat. When the temperature drops significantly, heating will be started again. Therefore, the later heat preservation state is intermittent heating, so the power consumption cannot be calculated on time.
