capacity
1-2 people: Choose a rice cooker with a capacity of 1.6-3 liters, such as the Midea 1.6-liter rice cooker, which is compact and lightweight, suitable for single people or couples. It can quickly cook a small amount of rice without wasting energy.
3-5 people: A 3-4 liter electric rice cooker is more suitable, such as a 4-liter electric rice cooker in Supor, which can meet the daily dining needs of ordinary families. The cooked rice tastes good, and can also be used to cook Congee, soup, etc.
More than 5 people: It is recommended to choose a rice cooker with a capacity of 5 liters or more, such as the Panasonic 5-liter rice cooker, which can cook enough rice for the whole family at once, even if there are guests visiting, it can be easily handled.
Heating method

Chassis heating: simple structure and affordable price. The heat is transferred to the inner pot through the bottom heating plate, which heats up relatively slowly. Rice is prone to inconsistent taste between the top and bottom, but it can basically meet the daily needs.
IH electromagnetic heating: Using electromagnetic coils to generate an alternating magnetic field at the bottom of the pot, the inner pot heats up on its own, heating more evenly and quickly, which can make the rice grains plump and taste better. However, rice cookers that use this heating method are usually more expensive. High end rice cookers from brands such as Xiangyin and Fuku often use IH electromagnetic heating technology.
Inner liner material

Aluminum alloy liner: lightweight, fast thermal conductivity, and relatively affordable price. But the surface usually needs to be coated with a non stick coating to prevent rice from sticking to the pot. If the non stick coating is damaged, the inner pot is easily corroded.
Iron pot liner: It has good heat storage capacity, which can make the rice heated more evenly, and the cooked rice has a sweet and fragrant taste. Moreover, the inner pot of the iron kettle is relatively sturdy and not easily deformed, but it is heavier in weight. For example, Supor's iron pot rice cooker is loved by many consumers.
Ceramic inner pot: Natural and environmentally friendly, with good insulation performance, the cooked food tastes delicious. At the same time, the ceramic inner liner is not easy to stick to the pot and is easy to clean, but its texture is brittle and prone to breakage.
