Air Fryer vs. Convection Oven: Which Should You Buy?
As an Amazon Associate, BuyerGuideLab earns from qualifying purchases — at no extra cost to you. It never changes a verdict. How we make money.
An air fryer is essentially a small, powerful convection oven. So why do people own both? Because speed and capacity trade off: the smaller the chamber, the faster and crispier it cooks — and the less it holds.
Quick answer: buy an air fryer if you cook small portions and want speed and crunch. Buy a convection oven if you bake, toast or cook for a family. Want both? An air fryer oven combines them, at a higher price.
Air fryer vs convection oven compared
| Air fryer | Convection (toaster) oven | |
|---|---|---|
| Speed | Fastest for small portions | Slower; larger space to heat |
| Crispiness | Best | Good |
| Capacity | 2–8 qt | Sheet pans, 12–13″ pizza |
| Toast & bake | No (basket models) | Yes |
| Typical power | 1,000–1,800 W | About 1,800 W |
| Counter space | Small | Large |
Which uses less electricity?
For small portions, usually the air fryer. Power draw is similar (roughly 1,500–1,800 W), but an air fryer needs little or no preheat and cooks faster. Example: a 1,750 W air fryer running 20 minutes uses about 0.58 kWh. A 1,800 W oven that needs 8 minutes of preheat plus 30 minutes of cooking uses about 1.1 kWh at full power. For big batches that fill the oven, the gap shrinks.
How we judged these: we compared manufacturer specs, verified owner reviews and independent test data. We did not hands-on test every model — where a claim comes from the manufacturer, we say so. Product boxes show live Amazon prices. Our methodology →

Frequently asked questions
Is an air fryer just a convection oven?
Technically yes — both use a fan to circulate hot air. An air fryer has a much smaller chamber and a stronger fan relative to its size, which is why it cooks faster and crispier.
Can a convection oven replace an air fryer?
Mostly. A convection oven will crisp food, just more slowly. Some convection ovens add an “air fry” setting with a faster fan.
Which is healthier?
Both cook with little oil. The health difference comes from what you cook, not the appliance.
Is an air fryer cheaper to run than an oven?
For small portions, usually yes, because it needs little preheat and cooks faster. For full-oven batches, the difference is small.
