Overview

A busy family kitchen with little counter space is where this Ninja stacked air fryer earns its spot, placing two baskets one above the other. Meal racks add a second level in each basket, so four foods cook together.

Stacked baskets give two-basket capacity without the width, and both zones finish together. The listed voltage looks non-US, which needs checking before purchase.

Who it's for

Households feeding up to eight get large batches and synced finishes. Single cooks will rarely use both baskets.

Pros and cons

Pros
  • Two baskets in a slim footprint
  • Cooks four foods at once
  • Synced finish across zones
  • Fits under standard cabinets
Cons
  • Listed voltage may not suit US outlets
  • Heavy at over eleven kilograms
  • Tall for low shelves

Performance notes

Even crisping relies on superheated air circulating around both levels in each basket. Smart Finish staggers start times so two different foods end together, which matters most for full meals.
