Preheat the air fryer to 380°F / 193°C for 3 minutes.
Rub the chicken thighs with olive oil, smoked paprika, garlic powder, and black pepper until evenly coated.
Arrange the chicken in a single layer in the air fryer basket and air fry for 12 minutes, flipping halfway.
Brush the barbecue sauce generously on both sides of the chicken and air fry for 4 to 6 more minutes until sticky, caramelized, and the internal temperature reaches 165°F / 74°C.
Rest for 3 minutes before serving to let the juices redistribute and the sauce set.
