Because most air fryers are countertop units that plug into a 15 amp outlet, vs most residential electric ovens that require 2x 240v 30 amp connections, or roughly 8x the available power…
That’s 14kW a whole range doesn’t pull that much on full blast. There’s plenty of ovens in the 3600W range meaning they run off bog-standard 240V@16A lines here but chances are you’re in luck and your kitchen has 20A three-phase… also 14kW (in star configuration), intended precisely for the range, roughly divided into two for the top and one for the oven. Not much more copper so it became standard quite a while back, while 30A would be massive. Also more neutral wires.
That’s a bit of a stretch since most residential ovens also have a range on top, so the power requirements are to cover multiple elements, not the oven alone. It’s probably actually less efficient, but still lower energy because you’re heating a smaller cavity.
Can’t speak for them, but I’ve had a smart monitor which shows live consumption. Took note of the consumption while using the oven against baseline consumption, and the same for the air fryer.
Air fryer consumed approximately half the electricity for an equivalent amount of time in my case, but it’s made better by the air fryer needing less time to reach temperature and cook whatever it is I’m making.
I can monitor my power usage via my solar panels and powerwall. The app lets you see how much you’re using at any given time, so I just turned on one appliance at a time to test their power consumption.
how do you even know that?

Plus the time savings of cooking faster in the air fryer than the regular oven to further compound those savings.

Smart meters have been a thing for over a decade now
This is how I know: https://shop.emporiaenergy.com/products/gen-2-emporia-vue-with-16-sensors-bundle
My air fryer only draws enough power to spin the fan, all the heat comes from natural gas.
You have one that goes on the stove?
Nah, inside. My oven is gas, so the air fryer in it isn’t powered by electricity. I was being a smartass.
