The average air fryer is 1450 watts. And the amount of electricity your air fryer uses will depend on what you are cooking and for how long. Let's say we're cooking some air fryer fried chicken, which will take around 30 minutes at 400*. Air Fryer Wattage: 1450 Time used: .5 hours 1450 watts X .5 hours = 725 watt-hours used 750 watt-hours / 1000 = .75 kWh to cook fried chicken in an air fryer. So if you ate fried chicken every day for a month (yum), in a month your air fryer would use 22.5 kWh of electricity.
