What is the Difference Between Running Watts and Starting Watts?

Knowing this can assist you in the energy consumption planning and the correct backup power selection or the most efficient fridge. 

What Are Running Watts? 

Running watts are the amount of electricity your refrigerator uses when it maintains the coldness of the food in it. This refers to the constant level of the energy consumed once the compressor has been started. In the case of the majority of modern fridges and their running watts can vary between 300-800 watts depending on size and functionality. This is the figure that largely dictates your daily electricity bill. 

What Are Starting Watts?

The surge of power required at the time of the first kick-on of the refrigerator compressor is referred to as the starting watts. This spike is needed to start the motor and it can be 2-3 times greater than the running watts. An example is a fridge that would ordinarily consume 400 watts of power but may temporarily consume 1200 watts upon startup. The compressor load normally results in a higher startup wattage of 2–3× than in running wattage.
