It's a small convection over marketed as an "Air fryer". It's genius marketing!
That's the big difference that I've noticed now that I'm reading about them.
It’s the same thing with instant pot where they probably lose out a bit by not marketing themselves as a serious electric pressure cooker that can also do other stuff.
"to cook something in hot fat or oil; to be cooked in hot fat or oil"
Because of what the word means?
