Ninja Double Stack XL DCT651

Manufacturer: Ninja

The Ninja Double Stack XL DCT651 is an oven-style air fryer designed for households that need generous cooking space without sacrificing versatility. With 12 preset functions spanning air fry, roast, broil, bake, toast, dehydrate, reheat, and keep warm, it covers a wide range of everyday cooking tasks from a single countertop appliance. Digital controls and a built-in preheat function make it straightforward to operate, while an interior light and viewing window allow you to monitor food during cooking without opening the door.

On the technical side, the DCT651 offers a 9.5-litre capacity and reaches temperatures between 40°C and 232°C, giving it a broad range suitable for gentle dehydrating as well as high-heat broiling. It draws 1800W during operation and features dual heating elements, which supports more even heat distribution across the cooking chamber. The unit measures 416 mm wide, 472 mm deep, and 337 mm tall, with a total weight of approximately 14.2 kg. Smart home connectivity is not supported, and the basket is not rated as dishwasher-safe. The appliance comes with a one-year warranty.

Who is this for?

This air fryer works well for households that regularly cook large portions, as its 9.5-litre oven-style capacity can handle bigger batches of food in a single session. Users who want versatility from one appliance will appreciate the 12 cooking functions, which range from dehydrating at low temperatures to broiling at up to 232°C. The built-in viewing window, interior light, and preheat function also make it a practical fit for those who prefer attentive, hands-on cooking without constantly opening the door.

Who is this NOT for?

Those with limited counter space will likely find this unit impractical, as its 416 mm width and 472 mm depth demand a generous footprint and its weight of over 14 kg makes repositioning cumbersome. Users who prefer a connected kitchen experience will also be disappointed, since the appliance lacks smartphone control and is incompatible with Alexa or Google Assistant. Additionally, those who prioritize easy cleanup may find the absence of a dishwasher-safe basket inconvenient for regular use.

The DCT651 measures 416 mm wide, 472 mm deep, and 337 mm tall, with a total volume of approximately 66,170 cm³, giving a clear sense of the counter space it occupies. It weighs 14,197 g, making it a notably heavy unit. The basket or pot is not rated as dishwasher-safe, so manual cleaning is required.

Final Verdict

The Ninja Double Stack XL DCT651 is a capable oven-style air fryer built around two clear strengths: a generous 9.5-litre capacity and a broad set of 12 cooking functions that handle everything from low-temperature dehydrating to high-heat broiling. Features like dual heating elements, a viewing window, an interior light, and a preheat function reflect a thoughtful approach to everyday usability. That said, its considerable size and weight mean it is better suited to a dedicated counter position than a flexible kitchen setup, and the lack of smart home connectivity places it firmly in the manual-control camp. For households that prioritize cooking versatility and batch capacity over connectivity and compact design, the DCT651 represents a well-specified, function-rich option within the oven-style air fryer category.
