Begin by preheating your air fryer to 400°F (200°C) as per the manufacturer's guidelines.
In a small bowl, mix together garlic powder, paprika, salt, and pepper to create a flavorful spice blend.
Lay the chicken drumsticks on a clean surface and generously coat them with the spice mixture, ensuring all sides are well-seasoned.
Carefully place the seasoned drumsticks into the air fryer basket and cook for 10 minutes.
After 10 minutes, flip the drumsticks using tongs and continue cooking for an additional 10 minutes.
Once cooked, let the chicken rest for 5 minutes before serving. Check that the internal temperature near the bone reaches 165°F (74°C) for safe consumption.
