Pre-heat the air fryer to 375 degrees.
Season the chicken wings lightly with kosher salt and dust with garlic powder on all sides.
Place the potato starch in a shallow bowl, then coat the chicken wings on all sides, shaking off any excess starch.
Transfer the wings to the air fryer basket with room between them so they aren't touching to allow for the air to flow on all sides.
Air fry the wings at 375 degrees for 20 minutes.
Increase air fryer temperature to 425 degrees and continue to cook for 15 more minutes; turning the wings a few times while they cook to ensure even crisping.
