One of our favourite Ninja air fryers has been slashed in price
The Double Stack XL is one of the flagship models from Ninja, the UK’s best-selling air fryer brand, and it has just dropped by £80.
Right now, that two-drawer trick belongs to the Ninja Double Stack XL, down from its £269.99 RRP to £189.99 through Amazon’s limited-time deal, a saving of £80, or 30% off, and one of its better prices in recent months.
Save £80 on the Ninja Double Stack XL, one of our more popular air fryers
The Ninja Double Stack XL has had £80 slashed off its price, making it a brilliant time to grab one of our most in-demand air fryers.
This air fryer has spent most of the past two years above £220, so £189.99 lines up with only a handful of moments when it has ever dipped this low, making now a genuinely good time to buy one.
Ninja Double Stack XL‘s headline trick is DoubleStack technology, which lets two separate 4.75 litre drawers each hold a rack, so four different dishes can cook at once instead of the usual single-basket queue that leaves half the meal waiting its turn.
Sync and Match settings let each drawer run its own temperature and time or copy the other exactly, and six cooking modes cover air frying, roasting, baking, reheating and dehydrating without ever needing a second appliance.
Despite the extra capacity, the Double Stack XL is 30% slimmer than Ninja’s previous AF400 and stands just 38.5cm tall, so it slots comfortably under most kitchen cabinets and still feeds up to eight people.
The bundle also throws in a set of silicone tongs and pairs with the separately sold Ninja Pro Connect app, which sends live cooking updates and finish times straight to a phone for anyone who likes to check dinner without opening the drawer.
Ninja says the DoubleStack technology cooks up to 55% faster than a fan oven while using up to 55% less energy, and the Air Fry function cuts fat by up to 75% versus deep frying. Every part is dishwasher safe, and registering it with Ninja adds a two-year guarantee.
For only £189.99, it is easy to see why the Double Stack XL keeps turning up on our best air fryers of 2026 shortlist at this price.
Stacking its dual drawers on top of each other, the Ninja Double Stack XL 9.5L Air Fryer SL400UK offers a staggering 9.5 litres of cooking space squeezed into a device that only takes up the same counter space as a singe-zone air fryer. New to this model is dual-layer cooking, so you can cook four different things at once, with the slight caveat that it can be fiddly to turn food during cooking. That minor issue aside, brilliant results and intuitive controls make this my favourite dual-basket air fryer.
