Ninja has introduced the latest addition to its air fryer lineup with the 9.5 litre Double Stack XL. This innovative model packs four cooking zones into a compact design, perfect for smaller kitchen spaces.
However, Ninja recently unveiled three new Double Stack models at IFA. While these are set to launch in the UK, their availability in the US remains uncertain.
We had the opportunity to get a hands-on look at these new models. You can compare them with the top Ninja air fryers and cookers currently on the market in our comprehensive round-up. Additionally, don’t forget to explore all the standout products from IFA in our IFA awards article.

The new Double Stack SL300, with a capacity of 7.6 litres, is even more compact than its predecessor. Despite its smaller size, it offers the same functionalities as the original model, allowing you to cook with two different methods simultaneously.
This model is designed to fit seamlessly on your kitchen counter without protruding beyond other appliances, making it a versatile choice for any kitchen. It features two cooking drawers, each with a 3.8L capacity, and offers six cooking methods including air fry, roast, bake, and more.
Priced at £229.99, the Double Stack SL300 is available in black and promises to be a convenient and efficient addition to your kitchen.

Featuring six cooking functions, including air fry, roast, bake, and dehydrate, the Double Stack XL with Smart Cook system offers versatility and convenience in the kitchen. Keep an eye out for pricing and release date announcements.

The third model unveiled by Ninja is a limited-edition white Double Stack XL. This model, similar to the original 9.5-litre version, offers a sleek white design and will be exclusively available at Currys.
While the white model adds a stylish touch to any kitchen, it may require more maintenance to keep it looking pristine compared to darker appliances. Keep an eye out for pricing details, and consider the original grey model for easier maintenance.
