How tall is it — will it fit under my cupboards?
It's 38.5 cm tall, which fits under most wall cupboards with a little room for steam. Measure your gap first.
How much counter space does it take?
About 28 cm wide and 47 cm deep — around half the width of a side-by-side two-drawer air fryer.
How many people does it cook for?
A family. It has 9.5 L across two 4.75 L drawers. Ninja says up to 8 people; TechRadar thought that was ambitious unless you add sides cooked elsewhere.
Can I cook two foods at once?
Yes. Each drawer has its own temperature and timer, and you can sync them to finish together.
What are the racks for?
Each drawer comes with a crisper plate and a wire rack, so you can cook on two levels per drawer — four in total.
What can it cook?
Air Fry, Max Crisp, Roast, Bake, Reheat and Dehydrate. Max Crisp is fixed at 240°C for frozen food.
Does it cook evenly?
Mostly. T3 found it didn't always cook evenly, so turn or shake food halfway.
How heavy is it?
About 10.3 kg.
Should I get this or the Ninja DualZone?
The Double Stack if your counter is narrow — it takes half the width. The DualZone if you have the space and want wider drawers for bigger items.
