Prep the wings: Pat the wings very dry with paper towels. Removing surface moisture helps them get crispy.
Mix the dry rub: In a small bowl, combine baking powder, salt, smoked paprika, garlic powder, onion powder, black pepper, and chili powder (if using).
Season the wings: Place wings in a large bowl.
Drizzle with oil and toss. Sprinkle the dry rub over the wings and toss again until evenly coated.
Preheat the air fryer: Set the air fryer to 390°F (200°C) for 3 minutes to heat up the basket.
Arrange the wings: Place wings in a single layer in the basket, leaving a little space between pieces. Work in batches if needed.
Air fry—first cook: Cook at 390°F (200°C) for 12 minutes.
Shake the basket or flip the wings halfway through.
Make the sauce: While the wings cook, stir together barbecue sauce, honey (or brown sugar), and apple cider vinegar in a bowl.
Air fry—crisp finish: Increase the temperature to 400°F (205°C) and cook 4–6 more minutes, until the skin is browned and crackly and the internal temperature hits 165°F (74°C).
Sauce the wings: Transfer hot wings to a clean bowl. Pour half the sauce over and toss to coat. Let them sit 1 minute to set the glaze.
Final gloss: Toss with the remaining sauce for a shiny, sticky finish.
Garnish if you like and serve immediately.
