The Ninja Double Stack XL SL400EUWH is a versatile air fryer designed to handle large meals without taking up excessive counter space. Its unique vertical design stacks two 4.75-liter drawers, providing a total capacity of 9.5 liters while maintaining a footprint that is 30% thinner than the AF400EU model. This layout allows you to cook substantial portions, such as a 1.4kg whole chicken in each basket, making it a practical choice for families or those hosting guests. Operating at 2470 W, this appliance offers six distinct functions, including air fry, max crisp, roast, bake, reheat, and dehydrate, with a temperature range from 40 to 240 °C. To help you coordinate your meal, the SYNC and Match functions ensure that different foods finished at the same time regardless of their cooking requirements. You can manage these settings via the side-mounted tactile electronic panel and digital display. Constructed with a white plastic housing, the unit measures 38.5 cm in height, 28 cm in width, and 47 cm in depth, weighing 10.3 kg. The non-stick coated drawers, crisper plates, and grill racks are dishwasher safe, which simplifies the cleanup process after preparing meals that cook up to 55% faster than in a traditional fan oven.
