Grate the potatoes and onion on the large holes of a box grater.
Transfer the mixture to a kitchen towel, pull up the sides of the towel, and squeeze out the moisture as much as possible.
Place the potato mixture in a large bowl.
To the potato mixture add the eggs, panko crumbs, salt, and pepper; stir until well combined.
Grease the air fryer racks or basket with cooking spray.
Drop the potato mixture in 2 to 3 tablespoon dollops into the air fryer, flattening the top to make a patty. DO NOT crowd the air fryer - arrange the latkes in one single layer, and cook them in batches.
Spray the tops with cooking spray.
Cook in the air fryer for 8 minutes.
Flip them over, grease with cooking spray, and continue to cook for 5 more minutes, or until golden brown and crisp.
Garnish with fresh chopped chives and serve with sour cream, apple sauce, etc...
