Capacities vary widely by model and use. Examples from the listings include a 30‑quart pot for large outdoor fryers, an 8‑liter oil capacity for electric dual tanks (16 QT total as two 8 QT tanks), a 5.3‑quart air fryer capacity, a 1 cubic‑ft interior oven capacity, and some units showing about 200 ounces capacity.
Options include adjustable thermostat controls and external/manual thermometer monitoring. For example, one electric dual fryer lists an adjustable range from 175°F to 390°F (79°C–200°C) and a 30‑minute timer. Outdoor kits often include a long‑probe thermometer that clips to the pot for continuous temperature monitoring.
Many electric fryers and air‑oven models include timers and one‑touch presets. Examples include a 30‑minute timer on a dual electric fryer and air‑oven models that advertise multiple one‑touch cooking functions and easy‑set digital controls for time and temperature.
