You should consider size, quality and inner core material.
You’d better buy a rice cooker with a moderate size, good quality, and a thicker core.
(1) You should choose a moderately sized rice cooker according to the number of people in your home.
If your family has 2~3 people, you should buy a rice cooker with a capacity of 4L.
If your family’s population is 3~5 people, I suggest you buy a rice cooker with a capacity of 5L.
If your family has more than 6 people, I suggest you buy a rice cooker with a capacity of 6L or 8L.
(2) You should carefully check whether the rice cooker can work normally.
You need to check whether the inner core and heating plate of the rice cooker are energized and heated.
You also need to check whether the control buttons and power button of the rice cooker are damaged.
In addition, you should buy a rice cooker with good power cord insulation.
The power cord with good insulation effect has good corrosion resistance and wear resistance.
(3) You should buy a rice cooker with a thicker core.
A rice cooker with a thinner core is easily deformed and has the problem of uneven heat conduction.
