there are many compact and small rice cookers available on the market, but the specific models and sizes may have changed since then. However, the smallest rice cookers are usually designed to cook individual portions or small servings of rice.
One common type of small rice cooker is the "mini rice cooker" or "personal rice cooker." These compact rice cookers typically have a capacity of around 1 to 3 cups of uncooked rice, which yields approximately 2 to 6 cups of cooked rice. Some mini rice cookers are specifically designed for dorm rooms, small apartments, or single-serving meals.
For the most up-to-date information on the smallest rice cooker currently available, I recommend checking online retailers or visiting local appliance stores to see the latest models and sizes. Keep in mind that manufacturers are continually innovating and introducing new products, so there may be even smaller rice cookers on the market now.
