The cooking chambers of the different Deep Fryers built for home use will have capacities made to hold a quart of oil while some larger models will hold several gallons and may be large enough to fry whole ducks or a medium-sized.

Digital temperature controls are common with adjustable thermostats that keep the temperature maintained. Temp controls may have ranges that begin at 300ºF and almost reach 400ºF or more at the upper end. For home use, the cooking oil in many Deep Fryers will heat to over 300ºF within 10 minutes.
