TL;DR
- Wattage: most air fryers draw 1000 to 1700 watts, similar to a kettle.
- But they run briefly, so a typical cook uses only about 0.3 to 0.6 kWh.
- Far less than an oven, mainly because there is no long preheat.
- Higher wattage is not worse; a powerful model that finishes fast can use less overall.
- Standby draw is negligible, so unplugging saves almost nothing.

An air fryer’s wattage looks high on the label, often around 1500 watts, which sounds like a lot. But wattage is a rate, not a total. What matters for your bill is watts multiplied by the hours you actually run it, and air fryers run for a short time.
This guide focuses on electricity use and wattage. For the cost in pounds or dollars per meal, see our air fryer running costs guide.
Wattage vs actual use
A 1500 watt air fryer uses 1.5 kilowatts while the element is on. But the element cycles off once up to temperature, and a typical cook lasts 15 to 20 minutes, so real use lands around 0.3 to 0.6 kWh. That is a fraction of what the wattage alone suggests.
Typical figures by size
| Air fryer size | Typical wattage | Energy per 20-min cook |
|---|---|---|
| Compact 2 to 4 qt | 1000 to 1200 W | ~0.37 kWh |
| Mid 5 to 6 qt | 1500 to 1700 W | ~0.53 kWh |
| Dual / large | 1700 to 1900 W | ~0.60 kWh |
| Electric oven | 2000 to 2500 W | ~1.5 kWh* |
*The oven figure includes a preheat, which is where most of the difference comes from.
Why higher wattage can cost less
A powerful air fryer that finishes a job in 15 minutes can use less total energy than a weaker one grinding away for 25. Wattage is the rate; the total is rate times time. So a strong fan and element are not a downside for your bill.
Standby uses almost nothing. A digital display draws a fraction of a watt. Unplugging your air fryer between uses saves so little it is not worth the bother.
Cutting the cost further
Skip the preheat when reheating, cook two things at once in a dual basket, match the size to the meal, and keep the element clean so cooks do not run long. Each small habit trims the total.
Frequently asked questions
Do air fryers use a lot of electricity?
No. Although the wattage is high, around 1500 watts, they run for only 15 to 20 minutes and the element cycles off once hot, so a typical cook uses just 0.3 to 0.6 kWh, far less than heating a full oven.
How many watts does an air fryer use?
Most draw between 1000 and 1700 watts, similar to a kettle, with larger dual and oven models reaching 1900 or 2000 watts. That is the peak rate, not the amount used over a whole cook.
Does a higher wattage air fryer cost more to run?
Not necessarily. Wattage is a rate, so a higher-wattage model that finishes faster can use less total energy than a lower-wattage one that takes longer. What matters is watts multiplied by cooking time.
Do air fryers use more electricity than an oven?
No, they use much less for small and medium meals, mainly because they skip the long oven preheat and heat a smaller space. An oven only pulls ahead when you fill it for a big batch.
Should I unplug my air fryer to save electricity?
There is no real benefit. Standby power for the display is a tiny fraction of a watt, costing pennies a year. Unplugging does no harm but saves almost nothing.
