What Can a 3500-watt Generator Run? The Right Way To Go About It

A 3500-watt generator can be a lifesaver during a power outage. It can provide enough power to keep your lights on, your refrigerator running, and your phone charged. It can also run a window air conditioner, making it a crucial tool for staying comfortable during a heatwave.

In addition to being a lifesaver during an emergency, a generator can also be a great way to save money on your electric bill.

By running your appliances off of a generator, you can avoid the high cost of using power from the grid. This can also be a great way to reduce your carbon footprint.

How to Choose a 3500-watt Generator?


Type of Generator

There are two main types of 3500-watt generators: portable and standby. Portable generators are smaller and can be moved around, while standby generators are larger and must be permanently installed.

Portable generators are typically used for camping, tailgating, or other outdoor activities. They can be used to power lights, appliances, and other devices. Standby generators are used to power homes or businesses during a power outage.

There are also two types of portable generators: inverter and conventional. Inverter generators are more expensive but more efficient and produce cleaner power. Conventional generators are less expensive but less efficient and produce dirty power.

Type of Fuel

You’ll need to decide what fuel you want your generator to use. Gasoline, diesel, and propane are the most common fuel used in generators. Each has its benefits and drawbacks, so you’ll need to decide which is best for your needs.


You’ll need to decide how much power you need your generator to generate. A 3,500-watt generator can power various small appliances, but if you need to run larger items, you will need a model with more power. A 3500 w generator is a good middle-of-the-road option, but you can choose a higher-wattage generator if you need more power.

Surge Wattage VS Continuous Wattage

If you’re looking at the specs for a power generator, you may notice two different wattage ratings: surge watts and continuous watts. So, what’s the difference?

Surge watts are the maximum amount of power that the generator can produce. You need this power for those big, one-off loads like starting up a power saw or running a fridge.

Continuous watts are the amount of power that the generator can produce continuously. This is the power you need for those smaller, constant loads like keeping the lights on or running a TV.

So, which one is more important? It depends on what you’re using the generator for. If you’re only going to use it for occasional, one-off loads, surge watts are more important. But if you’re using it for continuous loads, then continuous watts are more important.

Of course, the ideal situation is to have a generator that can handle both surge and continuous loads. That way, you’re covered no matter what you need it for.

3500-Watt Generator: What Can It Run?


A 3500-watt generator can power many kitchen appliances, including a refrigerator, a microwave, a coffee maker, and a toaster. With a generator of this size, you’ll be able to keep your kitchen running smoothly even when the power goes out.

A refrigerator is one of the most important appliances to keep running during a power outage, as it can keep food from spoiling. A generator with enough power to run a fridge will be a lifesaver during an extended power outage.

A microwave is another appliance that a 3500-watt generator can power. Microwaves use less power than many other kitchen appliances, so they are a good choice for running on a generator.

A coffee maker is another appliance that a 3500-watt generator can power. Coffee makers can use a lot of power, so ensuring your generator is powerful enough to run one is important.

A toaster is another appliance that a 3500-watt generator can power. Toasters use less power than many other kitchen appliances, so they are a good choice for running on a generator.

Larger appliances, such as washers and dryers, may not work well with a small generator.


A 3500-watt generator can power a lot of different appliances at once. You could simultaneously run a TV, DVD player, laptop, desktop computer, gaming console, external hard drive, sound system, and lights in the living room.

For example, a television may require between 100 and 300 watts, while a desktop computer may require between 300 and 500 watts. You might be able to run a small space heater off of a 3500-watt generator, but it would depend on the model and specs of both the heater and the generator.

It’s important to ensure that your generator can handle the power requirements of everything you want to run off of it, so check the specs before making your purchase.

A 3500-watt generator will run most appliances in an RV, but it may not be able to run all of them simultaneously. Generally, the larger the appliance, the more power it requires. In general, appliances that use gas, oil, or electricity to run (like a refrigerator, air conditioner, or stove) will require more power than appliances that use propane or natural gas.

If you are unsure whether or not your generator can run an appliance, it is best to consult an expert. Some appliances, like a refrigerator, may require a special converter to allow them to run from a generator.


A 3500-watt generator can run small appliances in an office setting. Appliances may include a desktop computer, a small printer, and a small television. The generator will not be able to power larger appliances such as a refrigerator or a window air conditioners.

Additionally, the generator should not be used to power any heating appliance, as this may overload the generator and cause it to malfunction.

What Will the 3500-Watt Generator Run At the Same Time?

A 3500-watt generator electric start can power up to eight standard appliances at the same time. This would include a refrigerator, a television, a computer, a microwave, and a toaster. It is important to keep in mind that while the generator can provide power to eight appliances, the total wattage of the appliances cannot exceed the generator’s wattage.

So, if you have a refrigerator that uses 600 watts and a television that uses 300 watts, those would be the only two appliances that could be run simultaneously. If you have a microwave that uses 1000 watts, that would be the third appliance that could be used.

Frequently Asked Question

What Are the Benefits of Buying a 3500-watt generator?

There are many benefits of owning a 3500-watt generator. Some of these benefits include:

  • The ability to power most household appliances and electronics.
  • The ability to keep the lights on during a power outage.
  • The ability to charge phones and other devices.
  • The ability to run a small air conditioner.
  • The ability to cook food.

How Long Will a 3500-watt Generator Run on a Tank of Gas?

A 3500-running-watt generator can work 9 hours on a gasoline tank. The amount of time the generator will run on a gasoline tank depends on the generator’s wattage, the tank’s size, and the type of gasoline. A 3500-watt generator will run for a shorter time on a tank of high-octane gasoline than on a tank of low-octane gasoline.

Can a 3500-Watt Generator Run 24 Hours a Day?

A 3500-watt generator can run for an extended period, but it is not recommended. The generator will likely overheat if run for more than 12 hours at a time. Additionally, the generator should be allowed to cool down for at least an hour after use before it is stored.
