Put on disposable gloves and rinse the jalapeños under cold water, patting them dry. Slice each in half lengthwise, then use a small spoon or knife tip to scrape out the seeds and white membrane (pith) from each half.
In a mixing bowl, combine softened cream cheese, shredded sharp cheddar, garlic powder, onion powder, smoked paprika, black pepper, and salt. Mix with a hand mixer or spatula until smooth and creamy.
Using a small spoon, rubber spatula, or piping bag, generously fill each jalapeño half with the cream cheese mixture, pressing slightly to adhere. Fill until flush with or slightly mounded above the rim.
Starting at the narrow tip, wrap one strip of thin-cut bacon tightly around each filled jalapeño half in a spiral, overlapping edges slightly. Secure the bacon end with a toothpick pushed through the bacon and into the pepper.
Preheat your air fryer to 375°F (190°C) for 3-5 minutes.
Place the poppers in the air fryer basket in a single layer, cut-side up with filling facing upward. Ensure they are not touching or overcrowded, cooking in batches if needed.
Cook at 375°F (190°C) for 10-13 minutes. At the halfway point (6-7 minutes), gently flip each popper with tongs to crisp the other side.
Carefully transfer cooked poppers to a serving platter using tongs. Let them rest for 2-3 minutes, then remove toothpicks before serving.
