# Ninja Air Fryer PRO 4.7L AF140UK review

> **Our verdict:** The Ninja Air Fryer PRO 4.7L AF140UK ranks 5th of the 10 air fryers we compare, with 7.9 out of 10. It takes our Value for Money badge.

No. 5 of 10 in our [air fryers ranking](https://vettedten.com/kitchen/air-fryers/) · Updated October 2026 · [How we rank](https://vettedten.com/how-we-rank/)

**7.9 out of 10** · Value for Money

The Ninja Air Fryer PRO 4.7L AF140UK has one 4.7 litre drawer and four settings: Air Fry, Roast, Reheat and Dehydrate. It suits a household of one or two; anyone feeding more will want a larger drawer or a dual-drawer model.

Why it's here:

- Small footprint, at about 28cm wide and 36cm deep
- Fits a whole 1kg chicken in the 4.7L drawer
- Owners report crisp chips and wings without preheating long
- Non-stick drawer and plate wipe clean easily

Keep in mind:

- Only four functions, with no bake setting
- Too small for a family of four in one batch
- Tops out at 210°C, with no window to check food

What the review sites say: None of the review sites we read has reviewed this model or named it in a best-of list, so it scores below the ones they have.

## Why the Ninja AF140UK scores 7.9

- What review sites say: 5th of 10
- How happy owners are: 2nd of 10
- How new it is: 4th of 10

### Why it sits behind the Philips 3000 Series Dual Basket Airfryer NA352/00

The Philips 3000 Series Dual Basket Airfryer NA352/00 (8.2) beats the Ninja Air Fryer PRO 4.7L AF140UK (7.9) because it does clearly better with the review sites.

## About the Ninja AF140UK

The AF140UK is a black air fryer with a single 4.7 litre drawer. The body measures 26.5cm high, 28.5cm wide and 36cm deep, and weighs 4.8kg. Ninja says the drawer takes a whole 1kg chicken. Expert Reviews lists room for 500g of fresh chips or 700g of frozen, four burgers or eight sausages, and found that a 1.3kg bird only went in after being flattened. While it runs, the manual asks for 15cm of clear space above and on every side.

There are four settings. Air Fry starts at 200°C, Roast at 190°C, Reheat at 170°C and Dehydrate at 60°C, and the arrow buttons change the temperature and time before or during a cook. The top temperature is 210°C. Expert Reviews gives Dehydrate a range of 40°C to 90°C and up to 12 hours, and Roast up to four hours. There is no manual mode and no bake setting. Pulling the drawer out to shake the food pauses the cook, and it resumes when the drawer goes back in. There is no shake reminder. A beep and End on the display mark the finish.

In the box are the main unit, the drawer, a crisper plate and a recipe guide. The drawer and plate are non-stick and dishwasher safe. The main unit gets a wipe with a damp cloth and never goes in the dishwasher or water. The cord is about 0.8m, the manual rules out extension leads, and the machine runs at 1750W. If food does not cook, the manual's first advice is to check the drawer is pushed fully in. Ninja's guarantee lasts one year, or two if you register the fryer within 28 days of buying.

## What owners report about the Ninja AF140UK

Owners keep returning to the same points: it is simple to use and easy to clean. Buyers commenting on Appliances Direct, with purchases from late 2024 to mid-2026, describe clear instructions and quick cooking, and say it is good value. The one suggestion for improvement there is a fuller recipe leaflet. On Mumsnet, owners call it big enough for two without taking over the worktop, and report using the oven far less.

Size is the caution. Mumsnet posters call this drawer big enough for two where the smallest Ninja is not. The advice on that thread leans towards buying bigger than you think if you will cook daily, because people who start small tend to outgrow the machine. Expert Reviews adds that larger loads are hard to shake in the small drawer, and that frozen hash browns came out crisper on top than underneath.

Long-term reports are thin. The model dates from 2024 and most owner comments cover the first year or two, so there is little yet on how the non-stick coating wears.

## Who the Ninja AF140UK suits

Buy it for one or two people who cook small batches and want an air fryer that stays out of the way. It is an easy first machine: the four settings are labelled on the panel, and Expert Reviews says the guidance and simple controls suit newcomers and light users. It needs a footprint of 28.5cm by 36cm plus 15cm of clearance.

Look elsewhere if you feed three or more or want to bake. The Ninja Max Pro Air Fryer 6.2L AF180UK is a bigger single drawer with six presets, bake among them, and a 240°C top temperature, though Expert Reviews says this smaller Ninja cooks almost as well. For two things at once, the Ninja Foodi Dual Zone AF300UK and the Tefal Easy Fry Dual XXL EY942 have two drawers. If you like to watch food brown, the Instant Vortex Plus Dual Drawer with ClearCook 140-3126-01-UK is the better fit.

## Questions about the Ninja AF140UK

### What wattage is the Ninja AF140UK?

1750W on a 220-240V supply, says Ninja's instruction booklet. Expert Reviews lists the same and found it used 0.617kWh in an hour at 200°C. John Lewis's listing says 2000W, but the 1750W figure is Ninja's own.

### What accessories can you use with the Ninja AF140UK?

Only accessories that Ninja recommends or sells, says its booklet. That booklet rules out paper, cardboard, plastic and roasting bags in the unit because they may cause a fire, and says nothing about foil. Spare parts and extra accessories come from Ninja's website or customer service.

### Where can I find the Ninja AF140UK manual?

On Ninja's product page for the AF140UK, which lists the instruction booklet and a quick start guide under User Guides. The booklet covers safety, the four settings, cleaning and troubleshooting, and how to register for the guarantee.

### How does the Ninja AF140UK compare with the Ninja Crispi?

They are different designs. The Crispi cooks in a 3.8 litre or 1.4 litre glass dish under a PowerPod that clips on top, with four preset modes and no temperature setting, while the AF140UK is one 4.7 litre drawer where you set both temperature and time. Mumsnet's review found the Crispi needs more flipping and attention, since the pod has to come off to turn the food.

### What's the difference between the Ninja AF140UK and the AF110UK?

The AF140UK has a Roast setting and the AF110UK does not: the AF110UK has just Air Fry, Dehydrate and Reheat. Otherwise, Brown Thomas's listing for the AF110UK gives the same 4.7 litre drawer, 26.5 x 28.5 x 36cm body, 4.8kg weight and 210°C top temperature.

## How we score it

Every score here comes from our ranking model; no editor sets the order. Most of each score is what the review sites say: the scores their own reviews give each model, and whether their best-of lists name it. For this guide we read BBC Good Food, Expert Reviews, Good Housekeeping UK, T3, TechRadar and Trusted Reviews. The rest is how happy owners are, held back where few owners have rated a product, and how new it is. Value for money earns its own badge rather than a higher place. We compared 19 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in October 2026.
