How much electricity does an air fryer use?

The formula in one line

Energy used in kWh equals watts divided by 1000, multiplied by hours. Multiply that by your electricity rate to get dollars per cook. The US average rate is $0.16/kWh as of 2026; state-by-state it ranges from about $0.10/kWh (Idaho, Washington, Louisiana) to $0.30/kWh (Hawaii, California, Massachusetts), so cooks in high-rate states roughly double the figures in the table below.

Worked example: an 18-minute chicken-breast cook on a 1500 W basket unit is 1500 ÷ 1000 × (18 ÷ 60) = 0.45 kWh, which costs $0.07at the US average rate. The element doesn’t actually run at full draw the whole time — most cooks average 70–80% duty cycle once the chamber is at temperature — so $0.07 is the upper-bound number; real-world is closer to $0.05.

Typical cost per cook

Six representative cooks at the US national average rate of $0.16/kWh. Numbers assume the element runs at full draw — real-world energy is 20–30% lower because the thermostat cycles the element off once the chamber is at temperature.

Cost shown at the US national average of $0.16/kWh. Multiply by your local rate ÷ 0.16 to recalculate — e.g. California at $0.30/kWh ≈ ×1.9, Idaho at $0.10/kWh ≈ ×0.6.

vs running a full oven

Full-size electric ovens preheat for 8–12 minutes (the cavity is 10× the volume of a basket air fryer) at around 3000–4000 W, then cycle at 60–70% duty during the cook. For small-batch food the air fryer wins on energy by roughly half because both the preheat is shorter and the chamber is smaller. The win shrinks once you fill the oven — a sheet-pan dinner for 6 is the same 1.5 kWh whether the oven feeds 2 or 6.

How to reduce cost further

• Batch back-to-back:Cook two items in one session while the chamber is already hot — the second cook skips the preheat entirely. Two back-to-back 15-min cooks run on ~0.7 kWh; two separate cooks (each with preheat) run ~0.85 kWh.
• Don’t over-preheat:2–3 minutes is enough for any basket unit; 4 minutes is enough for oven-style. Past that you’re burning ~$0.005 / minute for no extra texture benefit. See per-brand preheat times for your unit’s exact number.
• Pick basket over oven-style:If energy matters more than capacity, a 1500 W basket unit (Cosori 5.8 Qt, Philips 3000-series, Instant Vortex Plus) uses ~20% less per cook than a 1700–2100 W oven-style unit (Breville Smart Oven Air Fryer Pro, Cuisinart TOA-60). Most home households cook ≤4 servings — basket is the cheaper-to-run choice for that load.
• Reheat at 350 °F, not 400 °F:A 5-min leftover reheat at 350 °F draws ~60% of full wattage on average; the same reheat at 400 °F draws ~75%. Same crisp result for ~20% less energy. Per-food reheat times already use this calibration.

FAQ about air fryer electricity use

How many watts does an air fryer use?

Most home air fryers draw 1400–1800 watts at full power. Basket-style units (Cosori, Ninja, Philips, Instant Vortex Plus, Chefman) sit at the lower end — 1400–1700 W — because the chamber is small and the single heating element does not have to heat a large cavity. Dual-zone basket units (Ninja Foodi DZ-series) draw 1700–1800 W because both chambers run simultaneously when you cook in zone-sync mode. Full-size oven-style units (Breville Smart Oven Air Fryer Pro, Cuisinart TOA-60, Instant Vortex Pro, PowerXL Pro Plus 10 Qt) draw 1700–2100 W because the chamber is larger and there are usually two heating elements. The Philips XXL Premium tops the lineup at ~2100 W. Apartment kitchens running an air fryer alongside a microwave or toaster on the same 15 A circuit are within ~5 % of the breaker limit — running two of those three at once is what trips the breaker.

How many kWh does one air-fryer cook use?

Use kWh = watts ÷ 1000 × hours. A typical 18-minute chicken-breast cook on a 1500 W basket unit is 1500 ÷ 1000 × (18 ÷ 60) = 0.45 kWh — about $0.07 at the US national average rate of $0.16/kWh. Short reheats (5 min) come in around 0.13 kWh ($0.02). Longer cooks scale linearly: a 60-min whole-chicken on a 1700 W oven-style unit is 1.7 kWh (~$0.27); a 90-min pork shoulder is 2.55 kWh (~$0.41). Air fryers don't modulate wattage by cook temperature the way an oven element cycles — the element is at full power whenever it's heating, and what changes between a 350 °F and 400 °F cook is the duty cycle (how often the element is on), which averages out to about 70–80 % of full draw for any sustained cook.

Is an air fryer cheaper to run than an oven?

Yes for small batches — typically about half the electricity per cook because the cavity is one-tenth the volume of a full oven and the preheat is one-quarter the duration. A 1 lb chicken breast cook is roughly 0.45 kWh in an air fryer ($0.07) vs 1.2–1.5 kWh in a conventional oven preheated to 425 °F ($0.19–0.24). The win shrinks once you fill the oven — a sheet-pan dinner for 6 in a full oven is still 1.5 kWh but feeds 6, while running four air-fryer batches end-to-end to feed the same 6 people uses about 1.8 kWh. The /vs/oven page has the full per-axis breakdown. Air fryer vs oven — full breakdown

Does a dual-zone air fryer use more electricity?

Yes — both chambers draw power simultaneously, so a dual-zone unit cooking both zones at once is using around 1700–1800 W (vs 1500–1700 W for a single-basket model of similar capacity). Across one cook the energy difference is small (~10–15 %) because the dual-zone cooks two foods in one cycle that would otherwise take two back-to-back single-basket cooks (each with its own preheat). So if you're regularly cooking a protein and a vegetable side simultaneously, dual-zone is actually slightly more energy-efficient end-to-end. If you usually only cook one item at a time, single-basket is the cheaper-to-run option. See /brand for per-model wattage and zone counts. Per-brand calibration and wattage

Is there a low-power air-fryer mode?

There isn't an industry-standard low-power setting, but two patterns get close. (1) Cosori's Eco Mode (on the Pro II and TurboBlaze) trims the heating-element duty cycle on long cooks above 30 min — saves ~10 % over the run. (2) Lower cooking temperatures inherently draw less power because the duty cycle is lower: a 300 °F bacon cook averages ~60 % of full draw vs ~80 % for a 400 °F fry. The biggest practical saving isn't a mode — it's batching two cooks back-to-back while the chamber is still hot from the first (skip the second preheat entirely). Per-brand notes on energy modes are on /brand. Per-brand calibration

Does preheating cost a lot of electricity?

No — 2–3 minutes of preheat at full wattage is about 0.06–0.09 kWh, which is roughly $0.01–0.02 at the US national average rate. Even on a full-size oven-style unit (1700–2100 W) with a 4–5 minute preheat, you're at $0.02–0.03 per cook. That's an order of magnitude less than the cook itself on any cook longer than 10 minutes, and skipping the preheat to save it costs more in stretched cook time (1–3 extra minutes at full draw) than the preheat would have.
