Preheat an air fryer to 400 degrees F (200 degrees C) according to manufacturer’s instructions. Combine garlic powder, paprika, salt, and pepper in a small bowl.
Place drumsticks on a clean work surface. Sprinkle spice mix evenly over all sides of the drumsticks.
Place drumsticks in the basket of the air fryer and cook for 10 minutes. Using tongs, flip chicken over and cook for 10 minutes more. Rest for 5 minutes before serving. An instant-read thermometer inserted near the bone should read 165 degrees F (74 degrees C).
