Overview

• CHIP’s Testcenter measured 361 Wh to cook 300 grams of fries in a 1,800‑watt unit over 20 minutes at 200 °C, roughly €0.11 at €0.30/kWh.
• The tests explain that heating elements cycle on and off, so peak wattage does not reflect continuous energy draw, and full-size ovens are typically less efficient for small portions.
• Experts recommend matching fryer volume to typical portions to limit waste, with dual-basket models offering savings by running only one chamber for small batches.
• Business Insider reports the Cosori 5.5L XXL has 76,541 Amazon reviews averaging 4.6 stars as of August 2025, with the popular model currently discounted.
• CHIP’s sizing guidance notes mini air fryers around 4 liters can handle about 500 grams of fries, suiting singles or pairs, while larger capacities serve families and whole meals.
