That’s kinda cool! Most don’t do that.

As far as differences Alec at Technology Connections has a solid video pointing it out better. It’s more about the ratios involved between fan, element size, and volume of area to cook within. The result is basically the ratio skewed absurdly in the favor of air friers over ovens, plus putting out less total heat. So stronger fan is part of the equation at least!

It’s an air fryer, it’s always on. Otherwise that’s just a toaster oven.
