Ninja Foodi MAX Dual Zone AF400UK 9.5L Air Fryer - XXL Two Basket Cooking

Ninja Foodi MAX Dual Zone Air Fryer AF400UK puts the brand's two basket idea into a 9.5L countertop appliance that can cook up to six or more portions at once. With two independent 4.75L drawers, a digital control panel and six preset programs, it is positioned as a large-capacity hot air fryer for busy households that want crisp results with less added fat.

Design, Capacity And Core Specs

The AF400UK shares its core design with the AF400EU sold in continental Europe, but for the UK and US audience the most documented model is the AF400UK with a 9.5 liter total capacity split into two equal cooking compartments of 4.75 liters each.Argos lists the Ninja Foodi MAX Dual Zone AF400UK with a 9.5 litre capacity and two cooking compartments. The appliance is rated at 2470 watts of power, which is above many compact air fryers in the 1500-1700 watt range and supports rapid heating for larger loads.The same Argos listing specifies a power rating of 2470 watts. In physical terms, the AF400UK is specified at approximately H32.5 cm, W41.5 cm and D27 cm, with a weight of about 8.8 kg, which translates into a broad, low profile footprint that fits under many kitchen cabinets.Dimensions and weight are detailed on the same Argos product page.

On the front, the AF400-series devices use a drawer-style layout with two rectangular baskets and a central control interface with display and touch buttons. Independent heating elements and fans above each drawer enable separate temperature and time control for each side, which supports cooking two different foods simultaneously. The design is documented as being suitable for around six or more portions, which aligns with the stated 9.5L capacity and two whole chickens or large batches of fries per drawer in European documentation.On the AF400EU page, Ninja highlights capacity for up to 8+ people with two 4.75L drawers.

Cooking Functions, Temperature Range And Controls

The AF400UK is described with six preset cooking programs, which mirror those listed for the AF400EU model: Max Crisp, Air Fry, Roast, Bake, Reheat and Dehydrate.Argos notes pre-set programmes including max crisp, air fry, roast, reheat, dehydrate and bake. These modes apply different combinations of temperature and fan speed to adapt to frozen foods, roasts, baked items or low-temperature dehydrating of fruit and herbs. A variable temperature range from 40°C up to 240°C is specified for the AF400UK, and the AF400EU documentation also confirms the ability to adjust temperatures across a similar span for manual control.The Argos specification lists a variable temperature from 40°C to 240°CA Polish catalog entry for AF400EU also cites manual temperature adjustment in the 40°C to 240°C range.

Control-wise, the AF400UK uses a digital interface that allows selecting each drawer, choosing a program, and setting temperature and time for that side. Synchronization functions are a key part of the dual-zone design across AF400 models. Ninja documents Sync and Match modes on European product pages: Sync allows two drawers with different cook times to finish at the same time, while Match copies the time and temperature from one drawer to the other to cook a larger quantity of the same food.Ninja describes 2 independent cooking zones with SYNC and MATCH functions on the AF400EU page. These functions are also referenced by international retailers describing AF400EU and AF400UK, indicating a consistent feature set.

Included Accessories And Build Details

For the AF400UK, the box contents documented by UK retailers include two non-stick 4.75L drawers and two non-stick crisper plates, along with a recipe guide.Argos lists box contents as 2 x 4.75L non-stick drawers, 2 x non-stick crisper plates and a recipe guide. A German-language data sheet for AF400EU similarly lists a main unit, two air-frying drawers with non-stick coating and two non-stick crisper inserts, and notes a 2-year warranty term.A AF400EU product data sheet describes a 2-year warranty and lists 1 main unit, 2 air-fryer drawers and 2 crisper inserts. Both document non-stick surfaces and dishwasher-safe baskets, which affect everyday usability by simplifying cleanup.

The AF400EU data sheet specifies that each drawer can hold up to a 2 kg chicken or about 1.4 kg of fries, targeting family-sized portions.Capacity per compartment is stated as up to 2 kg chicken or 1.4 kg fries per drawer. When compared with many single-basket air fryers that list total capacities around 4 to 5 liters, this dual-zone design essentially doubles the usable internal space while keeping overall dimensions within typical countertop bounds described earlier.

Brand, Manufacturer And Market Context

Ninja is the consumer brand used on the air fryer itself. In the US, Ninja appliances are marketed and distributed by SharkNinja, a company with headquarters in Needham, Massachusetts and a US sales entity focused on kitchen and home appliances. Corporate information from SharkNinja identifies the brand Ninja as part of its portfolio, placed alongside vacuum and cleaning products under the Shark brand. This positions the Ninja Foodi MAX Dual Zone AF400-series as a kitchen appliance line within a broader consumer electronics and small appliance portfolio.

On European sites, Ninja Foodi MAX Dual Zone AF400EU is described in German and other languages as a hot air fryer with dual zones, and some listings emphasize that the model is fitted with a UK plug for AF400UK versions.An international retailer describes the Ninja AF400EU / AF400UK as a dual drawer air fryer with UK plug and 9.5L capacity. For US readers, the closest equivalent sold through US channels is a dual-drawer Ninja Foodi model with similar capacity and wattage, though exact plug type and part number differ between regions.

Performance Impressions And Independent Tests

Independent tests on AF400EU provide context for what to expect from the AF400UK in similar usage, given the shared hardware platform. A German test by Computer Bild describes AF400EU as a large dual-zone air fryer with two equally sized drawers, each quoted at 4.75 liters, and notes that each basket can take 1.4 kg of fries or a 2 kg chicken.A Computer Bild test of AF400EU highlights the two 4.75L baskets and capacity for 1.4 kg fries or 2 kg chicken per basket. The test notes that the evenly sized drawers offer more flexibility than some competitors with asymmetric capacities.

Another German-language comparison by Chip places the Ninja Foodi MAX Dual Zone AF400EU among the largest air fryers tested, again citing a total of 9.5 liters spread over two baskets and the six automatic cooking programs.Chip describes AF400EU as one of the largest hot air fryers in its comparison, with 9.5L capacity and six automatic programs. These tests typically focus on browning performance, ease of use and cleaning, all of which are influenced by the high wattage, wide temperature range and non-stick, dishwasher-safe baskets documented earlier.

Price Positioning And Value

For US readers looking to gauge price, the AF400UK is sold through UK retailers, while AF400EU appears on European sites. A German data sheet lists AF400EU at 249.99 in its local currency for the main unit.The AF400EU data sheet lists a price of 249.99 and a 2-year warranty. A magazine test from August 2024 cited street prices around 170 for AF400EU and 230 for the copper-accented AF400EUCP in the same period.Computer Bild mentions prices around 170 for AF400EU and 230 for AF400EUCP as of August 2024.

These figures place the AF400-series above the price level of many compact single-basket air fryers, which are often documented in ranges well below those amounts, but in line with other large dual-basket appliances that emphasize capacity and flexibility. When considering the AF400UK as an equivalent, readers should expect pricing that reflects its 9.5L capacity, dual-drawer construction and 2470W power rating as highlighted by UK and European sources, even if exact US dollar prices depend on regional listings and promotions at the time of purchase.

Comparison With Standard Air Fryers

Compared with single-drawer air fryers around 4-5L capacity, the Ninja Foodi MAX Dual Zone AF400UK offers almost double the internal space and the ability to cook two different dishes at once. Each 4.75L drawer can hold substantial portions, with European documentation citing either a full 2 kg chicken or 1.4 kg fries per side.The AF400EU data sheet specifies capacity per drawer at up to 2 kg chicken or 1.4 kg fries. The 2470W power rating also sets it apart from lower-wattage models that may struggle with large, dense loads, especially when both drawers are in use.

In terms of dimensions, the AF400UK's approximate 41.5 cm width and 32.5 cm height make it larger than compact 3-4L air fryers often listed around 30 cm width and under 30 cm height, but still within the range of what many kitchens can accommodate on a countertop.Argos dimensions of H32.5 cm, W41.5 cm and D27 cm illustrate the AF400UK footprint. The dual baskets, Sync and Match functions, and six programmed modes collectively push the AF400-series into a segment of multi-zone air fryers that trade compactness for capacity and versatility.

Use Case And Editorial Verdict

Within the hot air fryer category, Ninja Foodi MAX Dual Zone AF400UK is best understood as a high-capacity dual-drawer model aimed at households that regularly cook for four or more people and want the option to prepare separate dishes simultaneously. Documented capacity figures of 9.5L total volume, 2 kg chicken or 1.4 kg fries per drawer, and a power rating of 2470W support that positioning.The AF400EU specification sheet aggregates these capacity and power figures.

For US readers considering a dual-basket Ninja Foodi air fryer, the AF400UK and AF400EU specification set provides a clear picture of what the brand's large dual-zone models deliver: two equal 4.75L drawers, independent controls with Sync and Match functions, high wattage, non-stick, dishwasher-safe baskets and a two-year warranty period documented in European materials.The AF400EU data sheet confirms a 2-year warranty and lists the included accessories. In return for the larger footprint and higher price class relative to compact single-basket air fryers, the AF400-series offers the practicality of cooking complete meals in one appliance, which is its defining advantage within the air fryer segment.
