The power of coffee machine generally refers to the nominal rated power of power supply. Take household power supply as an example, 300W power supply refers to the maximum rated power of 300W, and its actual operating power can reach the peak of about 420 W in a short time. Peak power, the maximum power that the power supply can achieve in a short time, usually lasts only about 30 seconds.
In general, the peak power of the power supply can exceed about 50% of the maximum output power, because the energy required by the hard disk in the startup state is much greater than that in normal operation.
Good quality can be pulled to 600W, generally 550W, for reference only. You can run your generator, measure the voltage with a multimeter and turn it on until you find that the motor voltage drops sharply. This point is the peak power of your generator.
