Preheat Air Fryer to 350 F.
In a small bowl combine the salt, pepper, garlic powder, onion powder, smoked paprika and chili powder.
Place chicken drumsticks in a plastic bag and drizzle with olive oil. Toss to coat.
Sprinkle spice mix over the drumsticks to coat on all sides.
Place drumsticks in the air fryer basket and cook for 10 minutes.
Remove basket and flip chicken drumsticks, cooking for an additional 10 minutes until browned and crispy.
Time can vary based on chicken drumstick size so be sure to measure the internal temperature with a meat thermometer so it is at least 165 degrees.
