My favorite air fryer to use for this is my Ninja XL. It has a large basket and heats up quickly. I have made French toast in it so many times without having any issues with the bread getting soggy or sticking.
Once all those ingredients are whisked together well, dunk two pieces of bread into the mixture and coat each side. Hold up the soaked bread and let any extra batter drip away.
Once the basket is pre-heated, place the first two slices of soaked French toast inside your air fryer basket and close the door. Air Fry at 400°F for four to five minutes or until both sides are golden brown.
