No, I don't eat chips much so always done in the combi microwave on fan oven or in the main mutlifunction oven on fan cooking. The fan element for which is rated at 2kW, and is thermostatically controlled. The air fryers I have looked at briefly are 2.4-2.8kW so aren't that much cheaper to run over time.
Rated energy as you know is only what they can pull. They hardly ever actually pull that . Most of time it's pulling 0.5kwh
