Air fryers do not use a lot of electricity for most meals because, although they draw 1500 to 1800 watts, they cook quickly and need little or no preheat. A typical 15 to 20 minute cook uses far less energy than running a full-size oven for the same small portion. They cost more to run only when used for very long cooks where an oven’s larger capacity would do more work per unit of energy.

Quick Answer

Air fryers draw 1500 to 1800 watts but run for short times with little preheat, so they use less electricity than an oven for small and medium portions. For one to four portions they are usually the cheaper appliance to run.

Short Answer

No, air fryers are energy-efficient for everyday cooking. Their small chamber heats fast and finishes quickly, so a normal cook uses modest electricity, less than heating a big oven for the same small dish.

How Much Electricity an Air Fryer Uses

Energy use is power multiplied by time. An 1700 watt air fryer running for 20 minutes uses about 0.57 kilowatt-hours. The same food in an oven needs a 10 to 15 minute preheat plus a longer cook in a much larger cavity, which uses more. For small portions, the air fryer wins clearly.

Appliance Power Typical cook Rough energy
Air fryer ~1700W 20 min, no preheat ~0.57 kWh
Oven ~2000–2500W 15 min preheat + 25 min ~1.3–1.6 kWh

Key Takeaway: The savings come from skipping the oven preheat and heating a much smaller space. For one to four portions, an air fryer is the cheaper choice.

When an Oven Is More Efficient

When you cook large amounts, an oven spreads its energy across more food. Three full trays in one oven run can be more efficient per portion than several air fryer batches. If you regularly cook for a crowd, the oven earns its keep.

How to Keep Running Costs Low

  1. Skip unnecessary preheating for longer cooks.
  2. Cook a full single layer rather than tiny amounts repeatedly.
  3. Use the right size air fryer for your household.
  4. Keep the basket clean so cooking stays efficient.

FAQ

Is an air fryer cheaper than an oven to run?

For small and medium portions, yes. An air fryer heats a small chamber and skips a long preheat, so it uses less energy than an oven for one to four portions.

How many watts does an air fryer use?

Most full-size air fryers use 1500 to 1800 watts. Compact models use around 1000 watts. Higher wattage heats faster but for shorter times.

Does an air fryer use more electricity than a microwave?

An air fryer uses more power than a microwave and cooks for longer, so a microwave is cheaper for simple reheating. For crisping and cooking, the air fryer is still efficient versus an oven.

Bottom Line

Air fryers are energy-efficient for everyday cooking and usually cheaper to run than an oven for small and medium portions. Ovens win only for large batches. For a fuller comparison, see our air fryer vs oven guide and our best air fryers guide.
