Ninja Double Stack XL Air Fryer 9.5L SL400UK White 2 Drawer Air Fryer

Ninja Double Stack XL 2 Drawer Air Fryer 9.5L (SL400UK) – White

The Ninja Double Stack XL SL400UK is a space-saving, high-capacity air fryer designed with two vertically stacked drawers. It delivers powerful, even cooking while taking up less worktop space than traditional side-by-side dual air fryers.

With a total 9.5L capacity, it is built for families and busy households, allowing you to cook different foods at the same time and have them finish together using Ninja’s SYNC function.

Key Features

• 9.5L total capacity (2 × 4.75L drawers)
• Space-saving stacked vertical design
• 6 cooking functions: Air Fry, Max Crisp, Roast, Bake, Dehydrate, Reheat
• Cook 2 different foods at once with independent settings
• SYNC function for finishing both drawers at the same time
• MATCH function for cooking larger portions
• Includes stacked meal racks for multi-layer cooking
• Dishwasher-safe drawers, plates and accessories
• Designed for up to 8 servings
• Energy efficient cooking compared to conventional ovens

Cooking Performance

Each drawer has its own heat source and airflow system, helping to crisp and cook food evenly. The included racks allow up to four cooking layers at once, making it suitable for full meals, sides and batch cooking.

You can cook mains and sides separately while still serving everything together hot and fresh.
