In a large bowl, whisk together water, soy sauce, brown sugar, honey, and garlic powder.
Place chicken in the marinade. We used thighs but other pieces could be used, timing may change depending on thickness of meat. Marinate for 30 minutes or even over night.
Preheat air fryer to 350 degrees. Place chicken in a greased air fryer basket. Air fry for 16 minutes at 350 degrees, flipping halfway through.
Continue cooking until internal temperature reaches 160 degrees.
