Remember that the total wattage of all appliances and tools you plan to run simultaneously should be, at most, the capacity of your 3,500-watt generator to prevent overloading. Additionally, some motor devices, like refrigerators and air conditioners, may have startup surges that temporarily require more power than their running wattage.

Is a 3,500-watt Generator Suitable For Your Power Needs?

A 3,500-watt generator can be a suitable choice for power needs that don’t require much electricity. It’s important to note that the wattage of a generator refers to its output capacity, and different appliances and devices require different amounts of power to function.

For example, a refrigerator typically requires around 600–800 watts, while a window air conditioner may need 1,200–1,500 watts.

With a 3,500-watt generator, you should be able to power smaller appliances and electronics like laptops, TVs, and lights without any issues. However, you want to power more oversized items like a central AC unit or an electric water heater. In that case, you’ll likely need a higher-wattage generator.

It’s also essential to consider the duration of use when selecting a generator. A 3,500-watt generator may be suitable for short-term power outages. Still, you anticipate more extended periods without electricity. In that case, you should invest in a generator with a higher wattage rating or additional fuel capacity.

When deciding on a generator, it’s crucial to assess your specific power needs and choose a model that can provide sufficient power for your needs.


The main difference between the running and starting wattage of a generator is the amount of power it can produce. Running wattage refers to the continuous power output that a generator can sustain over an extended time, typically measured in watts or kilowatts.

Starting wattage, on the other hand, refers to the extra burst of power that a generator can provide for a short time to start up appliances or devices.

Continuous Wattage:

When it comes to generators, the running wattage is simply the amount of power the generator can continuously provide over an extended period. This is usually measured in watts or kilowatts and is a critical factor to consider when choosing the right generator for your needs.

The running wattage will vary depending on the specific make and model of the generator—still, the more powerful the generator, the higher the running wattage.

Surging Wattage:

The starting wattage of a generator refers to the amount of power the generator can provide for short bursts of time to start up appliances or devices that require more energy than to continue running. I also referred to surge or peak wattage, typically much higher than the running wattage.

For example, a refrigerator may only require 600 watts to run, but it could require 1800 watts to start up. Choosing a generator with enough starting wattage capability is essential to handle the startup needs of all the appliances and devices you plan to run during a power outage or other emergency.

In summary, understanding a generator’s running and starting wattage is crucial when selecting the right generator for your needs. The running wattage provides a continuous power supply. In contrast, the starting wattage provides the additional power needed to start up larger appliances or devices.

When calculating your power requirements, take both running and starting wattage into account to ensure that your generator can handle everything you need.

Calculating the required wattage of a generator for your needs involves a few simple steps:

you can simply visit the CAT Website to calculate your required generator or follow the easy steps.

  1. List all the appliances and devices you want to run during a power outage or other emergency.
  2. Determine the running wattage of each appliance and device. You can find this information on the product’s label or the owner’s manual.
  3. Add up the total running wattage of all the appliances and devices you want to run simultaneously. You will get the minimum amount of continuous power output that your generator will need to provide.
  4. Determine the starting wattage of each appliance and device. As mentioned earlier, many appliances and devices require more power to start up than they do to continue running. This information can also usually be found on the product’s label or the owner’s manual.
  5. Add the total starting wattage of all the appliances and devices you want to run simultaneously. This will give you the additional power needed to start these devices.
  6. Add the total running and starting wattage together to get the total wattage needed from your generator. This will give you the minimum wattage rating your generator should have to meet your needs.

It’s worth noting that this is a general guide, and certain appliances and devices may have specific generator requirements or recommendations. Refer to the owner’s manual or contact the manufacturer to clarify your power needs.

Here is a simple formula to check your required wattage:

You want to power a refrigerator (running wattage of 600 watts), a sump pump (running wattage of 800 watts), and a space heater (running wattage of 1500 watts). The space heater has the highest starting wattage at 3000 watts.

Total Running wattage = 600 + 800 + 1500 = 2900 watts. The highest starting wattage is 3000 watts.

Total Wattage Needed = Total Running Wattage + Highest Starting Wattage = 2900 + 3000 = 5900 watts

Therefore, you would need a generator that can produce at least 5900 watts to power all the appliances and devices on your list.

Can I run my appliances on a 3500-watt generator continuously?

Whether or not you can run your appliances continuously on a 3,500-watt generator depends on the specific devices you’re trying to power and their power consumption levels. Most small to medium-sized household appliances, such as lights, TVs, laptops, and refrigerators, typically use less than 1,000 watts.

If you add up the rated wattage of all the devices you plan to use at once, the total should be, at most, the peak capacity of your generator (in this case, 3,500 watts).

However, it’s important to note that running appliances continuously for an extended time can cause the generator to overheat and potentially fail.

I always recommend taking breaks between usages or investing in a higher-capacity generator if you anticipate the need for continuous power supply for long periods.

Additionally, it’s crucial to follow all safety guidelines when using a generator, including proper ventilation and placement, regular maintenance, and avoiding overloading the generator.

Familiarize yourself with the manufacturer’s instructions and consult a professional if you have concerns about safely operating your 3,500-watt generator.
