If you’re wondering how many watts you need in a generator to keep your refrigerator running during a power outage, you’re in the right place. A refrigerator typically requires around 700-800 watts to operate, so it’s important to choose a generator with enough power to keep your food fresh and safe. Let’s dive into the details and find the perfect generator for your needs.

Generators are crucial tools for providing backup power in times of emergencies, like when there are power outages due to natural disasters or maintenance issues. For many households, keeping the refrigerator running during these times is a top priority. But how many watts does a generator need to run a refrigerator?

The power consumption of a refrigerator can differ based on its size, make, and model. Generally, a standard refrigerator needs about 600-800 watts to start up and 100-200 watts to run continuously. This means that a generator with a starting wattage of 800-1000 watts and a running wattage of 200-300 watts should be able to power a refrigerator effectively.

It’s crucial for the generator to handle both the starting and running wattages to ensure the smooth operation of the refrigerator. Having some extra wattage capacity in the generator is also recommended to account for power surges or fluctuations.

When choosing a generator for running a refrigerator, consider other appliances or devices that may also need power during an outage. If you plan on using multiple appliances simultaneously, you may require a larger generator with a higher wattage capacity.

In summary, a generator with a starting wattage of 800-1000 watts and a running wattage of 200-300 watts should be sufficient for a standard refrigerator. However, it’s always wise to check the specific power requirements of your refrigerator and other appliances to ensure that your generator can handle the load. By selecting the right generator, you can ensure that your refrigerator remains operational during power outages, preserving your food and maintaining its safety.


1. What size generator do I need to run a refrigerator?
A: For most standard-sized refrigerators, a generator with a minimum of 1000-2000 watts should be sufficient.

2. Can I use a smaller generator to power my refrigerator?
A: It is possible to use a smaller generator, but it may not be able to handle the starting wattage required by the refrigerator, leading to potential damage or malfunction.

3. Will running a refrigerator on a generator drain the fuel quickly?
A: Running a refrigerator on a generator will use up fuel more quickly than running smaller appliances, as refrigerators require a consistent power supply to maintain temperature. It is important to have enough fuel on hand to keep the generator running for an extended period of time.
