Preheat the air fryer to 380°F.
In a small bowl, mix together garlic powder, paprika, onion powder, salt, and black pepper.
Pat the chicken breasts dry with paper towels and rub the spice mixture all over each piece.
Place the seasoned chicken breasts in the air fryer basket, ensuring they don't overlap.
Cook for 10 minutes, then flip the chicken breasts and cook for an additional 8 minutes.
Brush BBQ sauce over the chicken breasts and cook for 2 more minutes, or until the internal temperature reaches 165°F.
Let the chicken rest for a few minutes before serving.
