No, an air fryer does not use a lot of electricity. At equal wattage to other cooking appliances, air fryers use less electricity thanks to their size, the thermodynamics of air frying and consequently shorter cooking durations, and the lightning-quick preheating period. Unlike deep frying and grilling, baking, or roasting in an electric oven, the thermostat of an air fryer regulates the power consumption on the fly relative to the quantity of food being cooked, which ensures that only as much electricity as is needed is used instead of the full power draw pulled to sustain the heat of a large oven or deep fryer.
