Take frozen wings directly from the freezer (do not thaw or rinse).
Preheat air fryer to 180°C (356°F) for 3 minutes.
Toss wings in a bowl with salt, pepper, garlic powder, and baking powder (if using).
Place wings in the air fryer basket in a single layer, leaving space between each piece.
Cook at 180°C for 10 minutes.
Open the basket and carefully drain the water released from the wings (very important step).
Increase temperature to 200°C (392°F). Lightly spray with oil if desired.
Cook for another 12–16 minutes, shaking the basket halfway through.
Check that wings are crispy and reach an internal temperature of 74°C (165°F).
Rest for 2 minutes, then serve.
