How many kWh does an air fryer use per session?

A standard 1,500 to 1,800 W air fryer uses between 0.3 and 0.6 kWh per 20-minute session. This costs roughly 5 to 15 cents in electricity depending on your rate. By comparison, a traditional oven uses 1 to 2 kWh for the same cooking task, which is 3 to 4 times more energy.

How much can you save per year using an air fryer instead of an oven?

Using the air fryer 5 times per week instead of the oven, annual savings range from 40 to 80 euros depending on your electricity rate and habits. In Europe, with an average rate of 0.25 euros per kWh, a household saves about 60 euros per year. The air fryer pays for itself in 1 to 2 years.

Does an air fryer use more or less energy than a microwave?

A microwave uses slightly less energy (about 0.2 kWh for 10 minutes) because it heats food more directly. However, a microwave cannot make food crispy. For simple reheating, the microwave is more efficient. For cooking with texture and browning, the air fryer is the best compromise between energy and results.

Does an air fryer consume energy on standby?

Yes, connected models with digital displays consume 1 to 3 watts on standby, costing about 1 to 2 euros per year. Models with mechanical dials consume nothing when turned off. To eliminate all standby consumption, unplug the appliance or use a power strip with a switch after each use.

Can you power an air fryer with solar panels?

Yes, an air fryer is perfectly compatible with a home solar installation. Its moderate consumption of 0.3-0.6 kWh per use is easily covered by solar panels. Cook during daytime to maximize self-consumption. With a 3 kWp panel system, your air fryer effectively costs nothing in electricity.

Air Fryer Energy Savings: How Much Do You Really Save?

Does the air fryer really use less energy? The hard numbers

With electricity prices rising across Europe, kitchen appliance energy consumption has become a major purchasing factor. The air fryer is often presented as an economical alternative to the traditional oven. But is it true? We measured the real consumption of 12 air fryer models, 4 ovens, and 3 deep fryers to give you precise figures.

Understanding consumption: wattage vs actual energy

The wattage on an appliance label isn't its actual consumption. An 1,800 W air fryer doesn't draw 1.8 kWh per hour continuously — it heats in cycles, stopping once the target temperature is reached and restarting when it drops. In practice, an 1,800 W air fryer consumes about 0.8-1.2 kWh per hour of actual use.

Measured consumption per appliance (cooking 1 kg of chips)

Appliance	Rated power	Cook time	kWh used	Cost (0.25 euros/kWh)
Air fryer 4-5L	1,400 W	22 min	0.35 kWh	0.09 euros
Air fryer 7-8L	2,400 W	18 min	0.45 kWh	0.11 euros
Standard electric oven	2,500 W	35 min + 10 min preheat	1.50 kWh	0.38 euros
Fan-assisted oven	2,200 W	30 min + 8 min preheat	1.20 kWh	0.30 euros
Deep fryer	2,000 W	12 min + 10 min preheat	0.70 kWh	0.18 euros

Key finding: the air fryer uses 70-77% less energy than a standard oven and 40-50% less than a deep fryer for the same amount of chips.

Annual savings calculation

For a household using its air fryer 5 times per week replacing the oven, with an average 20-minute session:

Savings by country (208 kWh saved annually)

Country	Average kWh price (2026)	Annual saving
France	0.25 euros	52 euros
Germany	0.37 euros	77 euros
Belgium	0.33 euros	69 euros
Netherlands	0.29 euros	60 euros
Spain	0.22 euros	46 euros
Italy	0.28 euros	58 euros
UK	0.28 GBP	58 GBP

A 120-euro air fryer pays for itself in energy savings within 2-3 years in France, under 2 years in Germany.

Why the air fryer uses less: 3 technical reasons

Smaller volume: a standard oven is 60-70 litres; an air fryer is 5-10 litres. Heating a space 7-12 times smaller needs far less energy.
Minimal preheating: an oven takes 8-15 minutes to reach 200°C; an air fryer takes 2-4 minutes. Over 260 uses per year, this saves about 90 kWh.
Faster cooking: concentrated airflow and small volume enable 20-30% faster cooking times.

Consumption by meal type

Meal	Oven (kWh)	Air fryer (kWh)	Saving
Chips (1 kg)	1.50	0.40	73%
Whole roast chicken	2.10	0.75	64%
Grilled vegetables	1.00	0.30	70%
Grilled fish	0.80	0.25	69%
Frozen pizza	1.20	0.35	71%

Tips to reduce consumption further

Skip preheating for frozen food: saves 2-3 minutes of energy each time.
Cook in quantity: a two-thirds full basket is more efficient than a nearly empty one.
Clean regularly: a dirty appliance uses 10-15% more energy. See our maintenance guide.
Use dual baskets wisely: cook main and side simultaneously instead of two separate sessions.

Environmental impact

Saving 208 kWh annually reduces a household's carbon footprint by 40-90 kg CO2 (depending on energy mix) — equivalent to 400-900 km by car. The air fryer also eliminates the need for large quantities of frying oil. See our air fryer vs deep fryer comparison. For budget options, see best budget air fryers.
