Air fryer versus electric oven
Capacity, batches, preheating, cycling, and different cooking durations.
Read the air-fryer and oven comparisonNo universal winner: the Comparison Lab reports what the entered electricity scenarios cost. It does not prove equal cooking performance, food quantity, quality, capacity, or service.
Two comparison methods
Annual scenarios as entered
Each side keeps its own basis, schedule, quantity, and standby assumptions. This answers what the two entered annual scenarios cost; it does not make their output equivalent.
Matched use counts
Both per-use scenarios receive one visible, editable uses-per-week value. This improves arithmetic comparability, but equal counts still do not establish equal portions, batch capacity, runtime, or results.
Why measurement context matters
Equal wattage or identical minutes alone can mislead when appliances preheat, cycle, serve different batch sizes, or complete different tasks. Full-session measured kWh is often the stronger input because it can include real cycling and preheating. Standby remains separate.
The site compares electricity only. Purchase price, gas, water, carbon, food quality, and safety suitability are outside these comparison results. Manufacturer instructions remain controlling.
