The biggest here at 11 quarts in two 5.5-quart baskets, a quart more than the DoubleStack, for $60 less. Up to 450°F, a dishwasher-safe basket, a viewing window and a 3-year warranty against 1. Cuisinart publishes no wattage.
What’s the catch?

Not published by Cuisinart, so unproven: Power.

How this page was scored
A two-zone air fryer cooks a main and a side at different settings and can time them to finish together. The numbers that separate one from another are few: total capacity, how many zones run at once, wattage, the top temperature, whether the basket goes in the dishwasher, whether you can see the food without opening it, and how long the warranty runs.
Specs are weighted by how much they matter for a air fryer. An alternative earns full credit for matching or beating the Ninja DoubleStack XL on a spec, a proportional share where it falls short, and half credit for a spec its maker does not list. Models that list too few specs to compare fairly are left off. Read the full method.
Savings use maker or named-retailer list prices on the date shown. Amazon prices, where shown, are labelled with the time they were fetched. Spotted an error? Tell us.

Every number links to its sourceEach spec comes from the sheet the maker published, linked on the page, with the date the price was checked next to it.
We say what we do not knowA spec a maker never published is shown as not listed and scored at half credit. Nothing is estimated, guessed or filled in to make a table look complete.
