How much electricity does an air fryer use?

An air fryer uses roughly 0.3 to 0.5 kWh per 15-20 minute session, despite a rated power of 1,400 to 2,000 W. The heating element does not run continuously — it cycles on and off. At the German rate of €0.35/kWh, that is only 10 to 18 cents per cook.

Is an air fryer cheaper to run than an oven?

Yes, significantly. An air fryer uses about 0.4 kWh per cook versus 1.2 to 1.5 kWh for an oven, a saving of 50 to 70 % of electricity for the same amount of food. The gap is even larger for small portions, because the oven must heat a large cavity and needs preheating.

How much does an air fryer cost in electricity per year?

At the German rate of €0.35/kWh, using it 3 times a week costs about €22 a year, and daily use about €51 a year. These figures are estimates based on 0.4 kWh per cook and vary with the model, cooking time and how full the basket is.

Which air fryer models are the most energy efficient?

Models with moderate wattage and good heat management are the most efficient. Xiaomi and Cosori stand out with a good balance of power, cooking time and consumption (around 0.34 to 0.37 kWh per cook). In general, lower wattage for an adequate capacity is a good sign of efficiency.

Is there an EU energy label for air fryers?

No, there is no dedicated mandatory EU energy efficiency class for air fryers yet, unlike for fridges or washing machines. To assess consumption, rely on the wattage, the capacity in litres and real-world measurements from independent tests.

Air Fryer Power Consumption: Real Electricity Cost Explained (2026)

How much electricity does an air fryer really use?

Germany has some of the highest electricity prices in Europe (around €0.35/kWh), which makes the running cost of every kitchen appliance worth checking. The good news: despite a high rated wattage, an air fryer uses very little in practice — roughly 0.3 to 0.5 kWh per session, or about 10 to 18 cents of electricity per cook depending on your rate.

Rated wattage is not actual consumption

The most common mistake is reading the wattage (e.g. 1,700 W) and assuming the appliance uses 1.7 kWh per hour. The wattage only describes the maximum draw of the heating element at full load.

The element heats in cycles: it switches off once the target temperature is reached and restarts when it drops. Over a typical cook it is only active 50 to 70 % of the time. Most dishes are also ready in 12 to 25 minutes, not a full hour.

kWh = (watts ÷ 1,000) × hours × duty factor
Example: 1,700 W ÷ 1,000 = 1.7 kW × 0.25 h × 0.7 = ≈ 0.30 kWh

It also helps to separate the heat-up phase from the cooking phase. In the first few minutes the appliance draws full wattage to reach temperature quickly. After that, consumption drops sharply because the element only tops up the heat. Over a 20-minute cook, only three to five minutes fall in the energy-intensive heat-up phase. If you want your exact figure, a simple plug-in power meter between the socket and the appliance shows the kWh used in real time.

Measured consumption per session (15-20 min)

Appliance type	Wattage	Time	kWh (estimate)	Cost (€0.35/kWh)
Compact (3-4 L)	1,400 W	15 min	≈ 0.30 kWh	≈ €0.11
Standard (4-6 L)	1,600 W	18 min	≈ 0.38 kWh	≈ €0.13
Large (7-8 L)	2,000 W	20 min	≈ 0.48 kWh	≈ €0.17
Dual basket (9-10 L)	2,400 W	22 min	≈ 0.55 kWh	≈ €0.19

Annual cost: 3x a week vs every day

Based on an average of 0.4 kWh per session and a €0.35/kWh rate.

Frequency	Sessions/year	Use/year	Cost/year (€0.35/kWh)
1x per week	≈ 52	≈ 21 kWh	≈ €7
3x per week	≈ 156	≈ 62 kWh	≈ €22
5x per week	≈ 260	≈ 104 kWh	≈ €36
Every day	≈ 365	≈ 146 kWh	≈ €51

Even daily use stays modest at around €51 a year. Three times a week costs barely €22 of electricity annually.

Compared to a traditional oven

This is where the savings come from. An oven must heat a 60-70 litre cavity and needs preheating; an air fryer heats only 3-8 litres.

Appliance	Use per cook	Cost (€0.35/kWh)
Air fryer	≈ 0.40 kWh	≈ €0.14
Fan oven	≈ 1.20 kWh	≈ €0.42
Conventional oven	≈ 1.50 kWh	≈ €0.53

The air fryer saves 50 to 70 % of electricity versus the oven for the same amount of food. More in our guide to air fryer energy savings.

Compared to a deep fryer

A deep fryer must heat and hold 2-4 litres of oil at 170-180 °C.

Deep fryer: ≈ 0.6-0.8 kWh per session.
Air fryer: ≈ 0.3-0.5 kWh per session.

Plus the recurring cost of oil that must be replaced. See our air fryer vs deep fryer comparison.

Tips to cut consumption further

Skip needless preheating: often unnecessary, especially for frozen foods.
Batch cooking: a well-filled basket is more efficient than two small batches.
Use dual-basket models: main and side at once.
Clean regularly: a dirty unit can use 10-15 % more.
Use residual heat: chain cooks while the unit is still warm.

Consumption in everyday situations

Here are realistic estimates for common dishes at the €0.35/kWh rate:

Dish	Temperature / Time	kWh (estimate)	Cost (€0.35/kWh)
Frozen fries (2 people)	200 °C / 18 min	≈ 0.40 kWh	≈ €0.14
Reheat 2 bread rolls	180 °C / 6 min	≈ 0.15 kWh	≈ €0.05
Chicken thighs	190 °C / 25 min	≈ 0.50 kWh	≈ €0.18
Mixed vegetables	180 °C / 15 min	≈ 0.33 kWh	≈ €0.12
Reheated pizza	160 °C / 8 min	≈ 0.18 kWh	≈ €0.06

For reheating or cooking small amounts, the air fryer is unbeatable: firing up the oven would be pure waste. These small, frequent cooks are what create the biggest yearly saving versus the oven.

Connected models: keep an eye on consumption

Many air fryers are now Wi-Fi connected and app-controlled. That can help consumption: precise temperature and time programs avoid overcooking and wasting energy. On the other hand, a connected model with a display and Wi-Fi module draws 1 to 3 watts on standby continuously, roughly 9 to 26 kWh a year (€3 to €9), whether you cook or not. A switched power strip or a smart plug solves this by fully cutting power after use.

Most efficient models and the EU energy label

Models from Xiaomi and Cosori offer a great balance of power, cook time and consumption (around 0.34 to 0.37 kWh per cook). Note that there is no dedicated mandatory EU energy efficiency class for air fryers yet, unlike fridges or washing machines, so rely on wattage, capacity and real-world measurements. As a rule, lower wattage for an adequate capacity is a good sign of efficiency. See our pick of the best budget air fryers.

Conclusion

Even with high electricity prices, the air fryer remains one of the cheapest cooking methods for small to medium portions: around 0.3-0.5 kWh per session and a modest yearly cost (about €22 at three uses a week). It often pays for itself within one to two years on energy savings alone.

Do not be put off by the high wattage printed on the label. What matters is the real consumption in kWh, and it stays low thanks to short cook times, a small cavity and little to no preheating. By choosing an efficient model and applying a few simple tips, you keep electricity costs minimal for the long run, even against high rates.
