A large rice cooker can save you from cooking several batches when you feed a family, prepare meals ahead, or host guests. The MOOSUM 20 Cup Cooked Rice Cooker (MO-SMCB05US) combines a 10-cup uncooked rice capacity with a stainless steel inner pot, stainless steel steamer, and multiple cooking modes. Its biggest strengths are capacity and versatility, while its main tradeoffs are a fairly large footprint and some listing details that deserve a careful read. This review breaks down the verified specifications, practical use, cleaning, safety notes, and who should consider it.
Quick Verdict
Rating: 8/10, Recommended with caveats
Best For: Larger households, batch cooking, meal prep, and buyers who want a stainless steel cooking pot plus steaming capability.
Bottom Line: The MOOSUM gives you up to 20 cups of cooked rice and a useful set of cooking modes in one appliance. Its stainless steel pot is a notable advantage, but you should confirm counter space, current seller terms, and the exact program labeling before buying.

What Is the MOOSUM 20 Cup Rice Cooker?
The MOOSUM MO-SMCB05US is a large-capacity electric rice cooker designed to make up to 10 cups of uncooked rice, which the listing describes as up to 20 cups cooked. Amazon also lists the vessel capacity as 5 quarts. That makes it more appropriate for family meals, meal prep, parties, or other situations where a small three- or six-cup cooker would require repeated batches.
It is also meant to work as more than a basic cook-and-warm machine. The listing markets it as an 8-in-1 cooker and names rice, fry, milk porridge, yogurt, pasta, cake, soup, steam, and food warming. Because that wording appears to name more functions than the “8-in-1” label suggests, treat the product page and included controls as the final reference for exactly how each mode is counted.
Before You Buy: This is a high-capacity cooker measuring about 11.06 by 11.27 by 10.55 inches. Measure your counter or cabinet space first, and review the current Amazon listing for seller, warranty, and program details because the warranty term is not clearly stated in the verified listing information.
Key Takeaways
- You can cook up to 10 cups of uncooked rice, with a listed yield of up to 20 cups cooked.
- The stainless steel inner pot and steamer are useful if you prefer steel food-contact surfaces over a coated cooking pot.
- MOOSUM states that 4 cups of uncooked rice can cook in about 19 minutes, while also noting that time varies by rice type and quantity.
- The cooker automatically switches to a keep-warm mode that the listing says can run for more than 24 hours.
- The package includes the main accessories you need for measuring, steaming, stirring, and serving.
- Some details in the current listing, including the “8-in-1” naming and warranty information, are not fully clear, so check the product page before ordering.
Who Should Buy It?
Best For
- Families or hosts who regularly need more than a small batch of rice.
- Meal-prep users who want rice, steaming, soup, pasta, and other functions in one cooker.
- Buyers who specifically value a stainless steel inner pot and steamer.
Skip If
- You cook one or two servings at a time and want the smallest possible appliance.
- You need a clearly documented warranty, wattage, or other technical specification before purchase.
- You want a model with simpler, one-button rice-only operation and do not need extra modes.
Capacity and Cooking Performance
The main reason to consider this MOOSUM is capacity. A maximum of 10 cups uncooked gives you room for larger meals without splitting rice into multiple cooking cycles. For everyday use, you do not have to fill it to capacity, so the extra room can also be useful when your household size changes from day to day.
MOOSUM specifically claims that 4 cups of uncooked rice can finish in about 19 minutes, with the important qualifier that cooking time changes with rice type and quantity. That is a more useful way to read the speed claim than assuming every batch will take 19 minutes. Larger batches, different grains, and different water ratios can change total time.
Stainless Steel Pot, Steamer, and Build
The food-contact components are a strong part of the package. The listing says both the inner pot and steamer are made from food-grade stainless steel, and the general material specification is stainless steel. If you prefer to avoid a coated nonstick rice pot, this design gives you a clear alternative.
The tradeoff is that stainless steel can require more attention when cooking and cleaning. Rice starch can cling to the pot if ratios or resting time are off. Avoid assuming it will behave exactly like a nonstick insert, and follow the included guidance for rice and water amounts.
Cooking Modes and Versatility
The cooker goes beyond plain rice. The Amazon bullet list names rice, fry, milk porridge, yogurt, pasta, cake, soup, and steam functions, along with food warming. That range can reduce the need to use separate pots for simple one-pot meals, steamed vegetables, soups, or basic desserts.
The important limitation is program clarity. Amazon calls the appliance “8-in-1,” but its bullet wording names more than eight items when food warming is counted. This does not make the appliance unusable, but it is a good reason to review the control panel photos and instructions before buying if one specific mode is essential to you.
Auto Keep-Warm for Serving Flexibility
After rice finishes, the cooker is listed to switch automatically into keep-warm mode for more than 24 hours. That can be useful when family members eat at different times or when you prepare food before guests arrive.
Keep-warm capability is not a promise that rice texture will stay unchanged for an entire day. Moisture and texture can shift the longer cooked rice sits. Use the function as a convenience feature, follow the manufacturer’s instructions, and use normal food-safety judgment when storing leftovers.
Included Accessories
The package includes a stainless steel inner pot, stainless steel steamer basket, rice spoon, soup ladle, and rice measuring cup. That is a practical set because you can measure rice with the supplied cup, steam food above the main pot when the recipe allows, and serve without needing to buy a dedicated paddle or ladle right away.
Use the included measuring cup rather than assuming it matches a standard U.S. kitchen cup. Rice cookers commonly use their own calibrated cup and pot markings, so following the supplied measurements is the safer way to reproduce the intended rice-to-water ratio.
Pro Tip: For your first batch, use the included measuring cup and the cooker’s own water guidance instead of a generic rice ratio. Once you know how your preferred rice behaves in the stainless steel pot, adjust only in small steps.
How It Performs in Real Use
For Family Dinners
The 20-cup cooked capacity gives you more headroom than a small household cooker, so you can prepare rice for a larger table without running a second batch. The automatic keep-warm function also helps if serving time moves later than planned.
For Weekly Meal Prep
A 10-cup uncooked maximum is useful when rice is a regular part of several meals. You can cook a larger batch at once, portion what you plan to use, and refrigerate or freeze leftovers promptly according to normal food-storage guidance.
For Mixed One-Pot Cooking
The listed soup, pasta, porridge, steaming, and other modes make the appliance more flexible than a basic mechanical rice cooker. That is helpful when you want one countertop appliance to cover several simple tasks, but you should still follow the specific mode instructions rather than treating every program as interchangeable.
For Entertaining
The combination of high rice capacity and extended keep-warm is well suited to gatherings where food is prepared before everyone is ready to eat. The steamer basket also gives you another way to prepare vegetables or other suitable foods while keeping the main appliance in use.
Setup and Usage Tips
- Place the cooker on a stable, dry surface with enough open space for steam and lid movement.
- Use the supplied measuring cup and follow the product’s water guidance for the rice you are cooking.
- Do not exceed the cooker’s listed maximum capacity.
- Use the correct program for rice, soup, pasta, steaming, or other foods rather than guessing between modes.
- Let hot components cool before cleaning, and keep the electrical base away from soaking water.
- The Amazon care field says “Do not shake vigorously,” so handle the appliance and removable parts normally rather than shaking the unit to loosen food.
Food-Contact Materials and Safety
The verified listing describes the inner pot and steamer as non-toxic, food-grade stainless steel. That supports a straightforward material advantage, but the listing sections reviewed do not provide a separate certification that should be added to the article. The earlier claims about a heat-resistant exterior, non-slip feet, and a separate automatic shut-off safety system are therefore not repeated here.
As with any electric cooker, use it according to the supplied instructions, keep the base and electrical connection dry, and be careful around steam and hot metal surfaces. If a part is damaged, a cord is worn, or the appliance behaves abnormally, stop using it until the issue is resolved.
Cleaning and Maintenance
The removable inner cover, inner pot, and steamer should make routine access easier than a design with more fixed food-contact parts. However, the current Amazon information reviewed does not state that these parts are dishwasher safe, so do not assume dishwasher compatibility unless the manual or product label confirms it.
For stuck rice or starch, allow the removable pot to cool and soften residue with water before gentle cleaning. Avoid abrasive treatment that could scratch surfaces, and dry the removable parts before putting the cooker back together.
Pros and Cons
Pros
- Up to 10 cups uncooked and 20 cups cooked capacity.
- Stainless steel inner pot and stainless steel steamer.
- Multiple modes for rice and several other cooking tasks.
- Automatic keep-warm listed for more than 24 hours.
- Useful accessory set is included in the package.
Cons
- The “8-in-1” label does not perfectly match the number of functions named in the listing text.
- Warranty terms and some electrical specifications are not clearly stated in the verified listing sections.
- The larger capacity takes more counter space than a compact cooker.
Is It Worth the Price?
The MOOSUM makes the most sense when you will actually use its capacity, stainless steel pot, steamer, and extra cooking modes. Those features can offer strong value for a larger household because one appliance covers both high-volume rice cooking and several basic multicooker tasks.
It is less compelling if you cook tiny portions or want a very compact appliance. Since online pricing and seller offers can change, compare the current cost against similarly sized rice cookers and focus on the features you will use rather than treating the biggest capacity as automatically better.
How It Compares to Alternatives
Two relevant large-capacity alternatives are the Aroma ARC-150SB and Aroma ARC-5200SB, both sold as 20-cup cooked rice and grain multicookers. They are worth comparing if you want another high-capacity digital option. The MOOSUM stands out in this comparison when a stainless steel inner pot and stainless steel steamer are high priorities.
If your household rarely needs a large batch, a smaller six- to twelve-cup cooked model may be easier to store and more proportional to daily use. Capacity should match how you actually cook, not just the largest number on the box.
Frequently Asked Questions
How much rice can the MOOSUM MO-SMCB05US cook?
The listing states a maximum of 10 cups of uncooked rice, yielding up to 20 cups cooked. It also lists the vessel capacity as 5 quarts.
Does it really cook rice in 19 minutes?
MOOSUM says the cooker can prepare 4 cups of uncooked rice in about 19 minutes. The listing also says time varies with the type and amount of rice, so you should not expect every batch to finish in exactly 19 minutes.
Is the inner pot stainless steel?
Yes. The current listing identifies both the inner pot and steamer as food-grade stainless steel. That is one of the clearest reasons to choose this model if you prefer a steel cooking vessel.
What can you cook besides rice?
The listing names fry, milk porridge, yogurt, pasta, cake, soup, and steam functions in addition to rice and food warming. Check the control panel and manual for the exact program names and instructions.
How long does the keep-warm function run?
Amazon states that the cooker automatically switches to keep warm and can maintain that mode for more than 24 hours. Rice texture can still change over time, so use the feature as a serving convenience rather than a guarantee of unchanged texture.
What accessories come in the box?
The verified package list includes the inner pot, steamer basket, rice spoon, soup ladle, and measuring cup. These cover the basic measuring, steaming, stirring, and serving tasks.
What is the warranty period?
A specific warranty term was not clearly stated in the Amazon listing sections verified for this review. Check the current seller and manufacturer information before purchase if warranty coverage is important to you.
Who should skip this rice cooker?
Skip it if you cook only one or two portions, need a very small footprint, or require fully documented electrical and warranty details before ordering. A smaller or more extensively documented model may fit those priorities better.
The Bottom Line
The MOOSUM MO-SMCB05US is a strong fit for larger households and meal-prep users who want up to 20 cups of cooked rice, a stainless steel inner pot, steaming, and multiple cooking modes. It is less suitable for buyers who need a compact cooker or want every technical and warranty detail clearly documented before purchase. Overall, its verified capacity and stainless steel food-contact parts make it easy to recommend with those caveats.
