Recent developments in kitchen appliance technology highlight a trend toward vertical, stacked dual-basket air fryers designed to save counter space in smaller kitchens.

The Ninja Double Stack XL features two 4.75-liter baskets stacked vertically to achieve a 9.5-liter total capacity, utilizing side-mounted controls to accommodate its 47-centimeter height. It offers functions such as roasting, dehydrating, and air frying.

Similarly, the Philips 4000 Series Stacked Dual Basket Air Fryer utilizes a vertical design to provide a 10L capacity through two 5L baskets. While noted for its convenience and independent cooking settings, testing indicated the unit requires 15cm of clearance for ventilation and produces some fan noise.
