Cosori Air Fryer 4.7L Review: 35,000 Reviews Explain the Hype

What Is the Cosori 4.7L Air Fryer?

The Cosori 4.7L has accumulated over 35,000 Amazon UK reviews at 4.7 stars — a level of real-world validation that most kitchen appliances never reach. It is a square-basket air fryer with nine cooking presets, an LED touchscreen, and a non-stick dishwasher-safe basket. At £69.95, frequently reduced from £99.99, it sits at the value-mainstream crossover point for the category.

Design and Capacity

The square basket is the practical differentiator: it gives roughly 15% more usable cooking area than a round basket of equivalent stated volume. In practice this means a 1.5kg whole chicken lies flat, a 30cm pizza fits with modest trimming, and four large portions of chips cook in one layer without piling. The basket and drawer separate cleanly for loading and are confirmed dishwasher-safe.

Performance

Heat-up to 200°C takes 3–4 minutes. Chips from raw (6mm batons, soaked 15 minutes) take 18–20 minutes with a shake at halfway: crisp outside, fluffy inside without oil spraying. A 1.2kg tray of chicken thighs is done in 25 minutes, juicier than oven-roasted. The nine presets combine optimised temperature and time for each food type; the 11-step temperature range from 75°C to 205°C covers dehydrating through to full searing.

Fan noise at high speed is the main operational note — audible across an open-plan kitchen, comparable to a cooker hood at medium setting. Not intrusive, but present.

Verdict

The review count is not an anomaly. The Cosori 4.7L does the things most people buy an air fryer for — fast even cooking, a basket size that handles a family portion, and a basket that goes in the dishwasher — reliably and at a price that is hard to argue with. It is the default recommendation for a first air fryer in 2026.

Rating: 4.7/5 — The benchmark air fryer under £70.
