Place each pork chop between two sheets of plastic wrap. Using a meat mallet or rolling pin, pound them to an even 1/4 inch thickness. Season both sides with salt, black pepper, and garlic powder.
Set up a breading station with three shallow bowls. Place the flour in the first bowl. Place the beaten eggs in the second bowl. In the third bowl, combine the panko breadcrumbs and plain breadcrumbs.
Dredge each pork cutlet in flour, shaking off the excess. Dip in the egg, letting any excess drip off, then press firmly into the breadcrumb mixture on both sides, making sure the coating is thick and even.
Preheat the air fryer to 400°F (200°C) for 3 minutes. Spray the basket generously with cooking spray.
Place 2 schnitzels in the air fryer basket in a single layer. Spray the tops generously with cooking spray. Air fry at 400°F for 5 minutes.
Flip the schnitzels, spray the other side with cooking spray, and air fry for another 4 to 5 minutes until deep golden brown and crispy with an internal temperature of 145°F (63°C).
Repeat with the remaining schnitzels. Serve immediately with lemon wedges for squeezing over the top. The crust should be shatteringly crispy.
