Rice Cooker
Luxurious Brand. Many around are seemingly much cheaper.
Their insulation is not as thick so look tiny though cooking about the same amount of rice. They possibly have no steamer insert that than be used as the rice is cooking and steaming. They are unlikely to have a congee button and you could make congee which is a rice porridge. This congee function can be used in hot pot dinners. So put stock or water in and on a congee setting, the water will not shut off upon boiling as in the rice cooking function. In cooking rice, put the switch onto the rice setting. It will automatically turn itself to the keep warm setting. Wait for a few minutes maybe even half an hour after it switches to then enjoy your rice.
450 W, 550 W, and 700W rice cookers.
