Preheat the air fryer to 360°F for 3 minutes if the appliance manual recommends it.
Blot every wing thoroughly and trim any loose flaps of skin that could burn.
Toss with baking powder, salt, garlic powder, paprika and pepper until the coating is thin and even; add oil only if the skin looks unusually dry.
Arrange one loose layer and cook at 360°F for 12 minutes. Turn each wing and cook 8 minutes more.
Raise the temperature to 400°F and cook 3 to 7 minutes, turning once, until browned. Check several thick pieces and require at least 165°F.
Transfer to an open platter for 5 minutes. Serve plain or toss with a light sauce immediately before eating.
