Preheat the air fryer to 400°F (200°C). Pat 2 pounds of split chicken wings thoroughly dry with paper towels, pressing firmly until all surface moisture is gone.
Mix the dry rub in a large bowl. Combine 1 tablespoon aluminum-free baking powder, 1 teaspoon each of kosher salt, garlic powder, and smoked paprika, plus ½ teaspoon black pepper. Add 1 tablespoon oil and toss wings until evenly coated.
Arrange wings in a single layer with gaps between pieces. Cook at 400°F for 12 minutes without opening the basket.
Flip every wing and cook 8–10 more minutes. Skin should be deep golden and blistered — an instant-read thermometer at the thickest part should read 165°F.
Toss in sauce if desired. Warm ¼ cup hot sauce with 2 tablespoons melted butter, add hot wings, toss to coat, and serve immediately.
