Ninja Double Stack XL 2-Drawer Air Fryer SL400UK– Big Capacity, Small Footprint

Description

Wish you could fit a double air fryer in your kitchen but short on counter space? The Ninja Double Stack XL is here to help. With its unique vertical stacked design, this space-saving air fryer gives you all the benefits of a large-capacity dual drawer model, without cluttering your worktop.

Perfect for families and entertaining, it cooks mains and sides at the same time, with evenly crispy results on every level.


🥘 Space-Saving Design, Family-Sized Meals

  • 30% slimmer* than traditional side-by-side air fryers, yet still offers a generous 9.5L capacity.

  • Each 4.75L drawer fits a whole 1.4kg chicken – perfect for feeding up to 8 people.

  • At 38.5cm tall, it easily fits under most kitchen cabinets.


🍟 Double Stack Air Fry Technology™

  • Cook on 4 levels at once with the included stacked racks.

  • Independent heat sources and rear fans deliver 360° air circulation for even, crispy results.

  • Ideal for pairing mains with sides or batch-prepping party food.


🔄 2 Independent Drawers + SYNC

  • Mix and match 6 cooking functions, times, and temperatures in each drawer.

  • Use SYNC to have both drawers finish at the same time—so mains and sides are always served hot together.

  • Cooking for one? Just use a single drawer.


⚡ Fast & Energy Efficient

  • Cooks up to 55% faster than fan ovens*.

  • Uses up to 55% less energy than conventional ovens†.

  • Perfect for quick weeknight dinners or healthier family feasts.


🍰 6 Cooking Functions

Air Fry, Max Crisp, Roast, Bake, Dehydrate, and Reheat—so you can go from crispy fries to baked treats or even homemade jerky.


✨ Easy to Use & Clean

  • Sleek side-positioned control panel for quick, intuitive settings.

  • Dishwasher-safe non-stick drawers, racks, and crisper plates.

  • Includes chef-created recipe guide to get you started.
