Otoh tho 2 uses of the airfyer is almost certainly worse than a bigger single session with an oven. Personally I find meal prepping to be important way of saving time and energy alike.

also in winter both waste no energy since whatever energy is not used for cooking ends up warming your house.

I dint want to yuck anyone’s yum, but I dont have a lot of use for a tool that only has a benefit half the year when doing small batches.
