Our small Cozyna Air Fryer draws 1350 watts when heating.
Below comments applies only to 30 amp limited operation:
At 120 volts AC, that means it draws 11.25 amps when heating and much less when just "convecting" with the fan only.
While a unmodified 13.5k AC draws about 12-13 amps "on speed" cooling, current can spike up to 25 amps (for several seconds - usually not enough of an overload alone to trip the breaker) starting the compressor and fan.
On the face of it, using one AC and the Air Fryer is doable. However, a low battery that is charging, fridge or water heater on electric, or any large AC or DC current draw would pop a breaker (main or pedestal).
