The Ninja SL401 is a 10-quart, two-basket air fryer with a stacked design: the baskets sit one above the other so the unit fits under standard cabinets at about 15 inches tall. It runs 6 functions including air fry, broil and bake, with Smart Finish and Match Cook to sync or mirror the two zones, and it can cook two 5-lb chickens at once. It is a large-capacity machine at 1,690 watts and 23 lb, so it suits big households more than small kitchens. The best new price is $209.99 at Best Buy as of November 7, 2026, with 6 stores listing it new.
