Preheat oven to 425F.
In a medium bowl, toss sweet potatoes with olive oil, salt, garlic powder and chipotle chile powder.
Spread potatoes on a baking sheet. Avoid crowding so potatoes get crisp. Bake 15 minutes. Turn and bake an additional 10-15 minutes. Ovens may vary so keep an eye on them and be sure to cut all the potatoes the same size to ensure even cooking.
Preheat air fryer to 400°F.
Slice the potato into even ¼ inch thick fries. Toss with oil, salt, garlic powder, and chipotle chile powder.
Transfer to the air fryer basket, spritz the top with olive oil then cook 400F in a single layer without overcrowding the basket until golden brown and crisp on the outside, about 7 to 8 minutes, turning half way.
