Preheat the Air Fryer to 400, if yours requires preheating.
Set up your dredging station. Place flour in one bowl, eggs in a separate bowl and in the third bowl, combine the Panko, Parmesan, salt, garlic powder and black pepper.
Working in batches, coat the zucchini sticks in flour, shaking off any excess then coat in the eggs then coat in the Panko mixture so they are well covered on all sides.
Place the zucchini sticks in an even layer in the Air Fryer tray, leaving a little room between each one. Cook at 400 for 6-8 minutes, until browned and crispy.
Continue with remaining zucchini sticks until they are all cooked. If needed, you can put all of the zucchini fries in the Air Fryer together and heat for 1-2 minutes to warm all together.
Serve hot with marinara, Ranch, etc. for dipping.
