The Ninja Double Stack XL SL400EU is a high-capacity air fryer designed to save counter space by stacking two 4.75-liter baskets vertically. With a total capacity of 9.5 liters and 2470 W of power, it allows you to prepare larger meals or two different dishes simultaneously without taking up the footprint of a traditional side-by-side dual fryer. This gray plastic appliance features an LCD display and electronic controls, including a rotary dial, to manage six cooking functions: air fry, max crisp, roast, reheat, bake, and dehydrate. To help with timing, the Sync and Match features ensure that different foods finished at the same time and with consistent settings. An integrated anti-odor filter helps keep your kitchen air fresher during use, while non-slip feet provide stability on your worktop. Measuring 280 x 470 x 385 mm and weighing 10.3 kg, the unit comes with non-stick baskets, crisper plates, and stacked meal racks that expand your cooking area. These components, along with the drawers, are dishwasher-safe, making the cleanup process straightforward for anyone cooking for a family or hosting guests.
