Ninja Double Stack XL SL400UKCP
9.5L, dual drawer, Black/Copper
Editorial review Reviewed 18 October 2026 How we assess products
The Double Stack puts its 9.5 litres above each other instead of side by side. At 28cm wide, it solves a different problem from a small-capacity air fryer: a family can keep two zones while freeing up counter width. The supplied racks let you separate a protein and side in each drawer. Layered cooking is useful, but it adds racks to load, lift and wash. Good chips and mixed meals are within its reach; do not treat four levels as a promise that every food will brown evenly without attention. It is audible in use, tall, and considerably deeper than its narrow front suggests. Hand-washing the non-stick drawers can help preserve their finish. The selected black/copper Amazon listing was unavailable at our 18 October check; confirm stock before choosing this colourway.
