Rice Cooker Wattage Key Takeaways

Before we dive deep into rice cooker wattage, here are a few key takeaways.

  • The rice cooker wattage generally lies between 300W and 1500W.
  • Some factors influencing the wattage include size, cooking time, functionality, etc.
  • A small rice cooker can consume nearly3kW of electricity in an hour.
  • If you are using a rice cooker for one hour every day, it will typically draw9kW in a month and 108kW in one year.

How Many Watts Does A Rice Cooker Use?

Any standard rice cooker consumes 400 to 1000W of electricity in cooking mode and draws 30 to 50W in the warm mode. Every time you use the rice cooker, it will draw 0.7kW and cost $0.043 per use. On the other hand, a typical rice cooker uses 0.5kW per hour and $0.048 cents per usage. However, this is not the exact watt consumption. Instead, the rice cooker's wattage varies depending on the brand, model, and size.



Capacity in Liter

Suitable For

Small Rice Cooker

300 to 500 watts

0.2 - 0.7 liters (1 to 3 cups)

Individuals or small households.

Medium Rice Cooker

600 to 900 watts

0.9 - 1.9 liters (4 to 8 cups)

Small to medium-sized families.

Large Rice Cooker

What Factors Affect A Rice Cooker Wattage?

Rice cookers are great appliances, but they consume a lot of energy, which determines the wattage. Here are the key factors affecting the rice cooker wattage.

Size and Capacity: The cooker's size and capacity affect the total energy usage. A large rice cooker uses more energy than a smaller one — even if you are cooking the same quantity of rice.

Rice Cooker Functionality: The more functions a rice cooker has, the more watts it will consume. For example, the "keep warm" function can maintain the cooked rice temperature for a long period. Although the feature is convenient, it draws a lot of electricity and increases the watt consumption.

Cooking Time: The duration for which the rice is cooked directly impacts the wattage consumption. When you cook for long hours, it will require more energy.

Insulation and Construction: A well-insulated rice cooker is designed to retain heat effectively, which reduces the need for additional power to maintain the required cooking temperature.

Water Usage: When you are using too much water, the rice cooker will need more energy to boil off the excess water. The correct rice-to-water ratio is one of the best ways to reduce energy usage and watt consumption.

How Much Does It Cost to Run A Rice Cooker?

A low-wattage rice cooker typically uses between 620 and 700W of electricity during the cooking process. If the rice cooker draws anywhere around 627W or 0.627kW of electricity, the operational cost is around $0.0013. The cost per hour, in this case, is $0.07. If you are leaving the rice cooker on warm for an hour, it will cost $0.14 per day. That means running a rice cooker will cost around $4-5 per month.

One way to offset the high electricity bills is using a solar generator. It uses free solar energy to power home appliances, helping you reduce the high electricity bills. Jackery Solar Generators are portable and powerful charging solutions for most appliances, like rice cookers. They are lightweight, so you can carry the power station anywhere for indoor and outdoor use to supply interrupted power supply.

Jackery Solar Generators for Rice Cookers

Jackery is the leading brand that manufactures solar generators, power stations, and solar panels. The Jackery Solar Generators combine the Jackery Explorer Portable Power Stations and Jackery SolarSaga Solar Panels to charge home or outdoor electrical devices.

The solar generators are portable, lightweight, and powerful batteries that can charge rice cookers during power outages, camping, RVing, blackouts, or brownouts. The solar panels capture the direct sunlight and convert it into DC. The built-in inverter of the power station converts the DC to AC electricity to power devices like rice cookers.

Jackery Solar Generator 2000 Plus 

The Jackery Solar Generator 2000 Plus has a LiFePO4 battery of 2042.8Wh capacity and can be expanded to 24kWh using the additional Jackery Battery Pack 2000 Plus.

How to Save The Cost of Running A Rice Cooker?

Rice cookers draw a significant amount of electricity that eventually contributes to the electricity bills. Here are a few tips to reduce the cost of running a rice cooker.

  • Select the right size rice cooker that aligns with how much rice you want to cook. A small rice cooker would be a great option if you want to cook rice in smaller quantities.
  • Avoid adding excess water, which can often lead to long cooking times.
  • Before cooking rice, soak them for 20-30 minutes. This will reduce the cooking time and even energy consumption.
  • While cooking, keep the cooker's lid closed to avoid heat and pressure loss.
  • Power your rice cooker with the help of solar generators to eliminate the cost of running a rice cooker.
  • The "keep warm” mode consumes a lot of power, so minimize its usage.
  • Always keep the rice cooker clean, as dirty appliances can increase power consumption and reduce its efficiency.

Rice Cooker Wattage FAQs

How many watts does it take to cook rice?

The rice cooker's wattage consumption will depend on the specific recipe and quantity of ingredients. Generally, it takes around 15 or 20 minutes to cook rice in a 1000W cooker.

Do rice cookers use a lot of electricity?

All rice cookers are generally considered to be energy-efficient cooking appliances and consume little electricity. The actual power consumption of the rice cooker will depend on size, specific model, and additional features.

What size of generator do I need to run a rice cooker?

If you are using a 500W rice cooker for 2 hours every day, the daily electricity consumption can be calculated as follows:

Watt-hours or Kilowatt-hour = Wattage × Hours of Operation = 500W × 2H = 1000Wh

Let's take an example to understand better:

Suppose you use Jackery Solar Generator 2000 Plus to charge a rice cooker of 1000W. The running time of the generator can be calculated as follows:

Working Hours = Battery capacity * 0.85 / Operating wattage of the appliance = 2042.8Wh * 0.85 / 500W = 3.4H.

How does the wattage of a rice cooker affect its performance?

The rice cooker's wattage determines how quickly the appliance can cook rice. In other words, higher-wattage rice cookers can cook rice more efficiently and faster than low-wattage rice cookers.

Is it more energy-efficient to use a rice cooker or cook rice on a stove?

A rice cooker is typically more energy-efficient than a stove. This is because a rice cooker is designed to use minimal energy and can switch to a "keep warm" mode automatically after the rice is cooked.

Final Thoughts

With the help of rice cooker wattage, you can understand its usage and efficiency. Rice cookers typically consume 300 to 1500 W of electricity, which can contribute highly to your bills. If you wish to maximize energy efficiency and reduce the high electricity bills, you can trust solar generators. Jackery Solar Generators are designed to power all different sizes and capacities of rice cookers. These solar generators are powerful and portable enough to charge all appliances for long hours.
