Preheat the air fryer to 400°F / 200°C for 3 minutes.
Pat the chicken wings dry, then toss with olive oil and arrange in a single layer in the air fryer basket.
Air fry for 18 minutes, flipping halfway, until the skin is golden and crisp and the internal temperature reaches 165°F / 74°C.
While the wings cook, whisk together melted butter, lemon pepper seasoning, lemon zest, lemon juice, and garlic powder in a large bowl.
Transfer the cooked wings to the bowl and toss immediately in the lemon pepper butter until evenly coated.
Serve right away while the coating is bright and the wings are hot.
