What Appliances Will A 3500 Watt Generator Run?

These days, the market is filled with a wide variety of appliances. What Appliances Will A 3500 Watt Generator Run? The solution might surprise you. The amount of watts that various appliances require varies, so it’s critical to understand how much electricity you’ll need to operate your desired equipment.

We’ll examine some of the most popular appliances and give you an idea of each wattage requirement. We’ll also offer some advice on how to pick the best generator for your requirements. So let’s get going.

What Appliances Can A 3500-Watt Generator Run?

You may use 3500-watt generators to power an extensive selection of appliances. You can utilize the lights, microwave, and other common household appliances. It is also possible to utilize larger appliances, such as washing machines and dryers. However, operating many things at once can tax your generator’s resources.

A 3500-watt generator should be enough to power most of your home’s small appliances. They are often not advised to power significant home equipment, such as the central air conditioning or heating system. Though in some circumstances, it could be feasible.

  • Refrigerators: about 700-1000 watts; (1800-2400 if it has an ice maker)
  • Washing Machines: about 800 watts; (1750 if washing and spinning at the same time)
  • Clothes Dryers: about 3400 watts; (3500-5000 for larger capacity dryers)
  • Microwaves: about 1000 watts; (1800-2400 if it has a light inside)
  • Electric Blankets: about 300 watts.
  • Boilers: these are not recommended for use with 3500-watt generators; (but you can try it if you wish)
  • Central Air Conditioners: these are not recommended for use with 3500-watt generators; (but you can try it if you wish)
  • Pool Pumps: these are not recommended for use with 3500-watt generators; (but you can try it if you wish)

Any generator used to power a central heating system will soon deplete its fuel supply. Put a heater into the generator if necessary, but remember that the generator’s fuel will run out quickly.

If the generator can power the heating system, then there’s no reason it can’t also power the air conditioning. It is because of the strict regulation of the temperature. While centralized heating systems adjust their power use based on demand, central air is designed to run nonstop, rain or shine. While a generator of greater power might accomplish this, a 3500-watt generator isn’t designed for such tasks.

How To Determine The Wattage Of Your Appliances

No appliances demand 3500 watts of power, but you still need to be aware of what each appliance’s wattage needs are. Look at the surge wattage rating if you know how many watts an appliance consumes. The amount of electricity an appliance requires to start depends on its surge rating. The amount of power required drops dramatically once it starts.

You can calculate how much wattage your generator needs to produce if you know how many watts an appliance consumes. However, if you only need a ballpark figure, include the wattage ratings of the devices hooked into the generator.

What Will a 3500-Watt Generator Run?

Most household appliances in a typical house only require 3500 watts of power to run. Here are some products that a 3,500-watt generator can power to give you an idea of what is covered. Although not exhaustive, this list does contain some of the most popular appliances.

  • Full-size freezer or refrigerator
  • Window AC unit
  • A desktop computer – A laptop
  • Numerous TVs and home theatre systems

Remember that your actual outcomes may differ. For instance, a window air conditioner might consume up to 2,700 watts. You may need to replace your generator if you want to use more extensive appliances like an electric stove or microwave.

If you want to go all out, you could run a chest freezer and a tiny window air conditioner simultaneously. Just make sure the two appliances have the same power (2,700 watts) to prevent the generator from being tripped by their operation.

What’s The Difference Between Inverter And Conventional 3,500-Watt Generators?

When looking for a generator, you’ll see two distinct designs: conventional and inverter. Generally, conventional generators are less expensive to operate than inverter generators. Still, they may be more difficult to start while under load or to get your appliances up to full power.

Square Wave

  • The voltage output from conventional generators is called a “square wave,” and it varies in a series of steps instead of constantly. Many appliances may find it challenging to manage this.

Lights and fans are the most delicate applications for conventional generators since they don’t require precise sensitivity. The erratic electricity that a traditional generator produces can harm equipment like computers.

Modified Sine Wave

  • The voltage generated by inverter generators is a “modified sine wave,” which seamlessly transitions between the + and – connections of the inverter. Because they employ a technique that resembles how the power provider provides power, inverter generators handle delicate electronics better.

Inverter generators work best with devices like laptops or televisions that demand precisely regulated electricity. An inverter generator’s “modified sine wave” can harm standard equipment.

Because of their much higher price than conventional generators, inverter generators are not recommended for use by most residential consumers. They work well at building sites and other places where precisely regulated electricity is needed.

Even yet, given that so many appliances are switching to more energy-efficient models, you might not even need a generator. Check the wattage of every appliance you use by looking around your house. You should update or consider buying a generator if you see anything above 1,500 watts.

How To Choose The Right Generator For Your Needs

You must be aware of your power requirements if you want to select the best generator. Here are some practical suggestions for selecting the proper wattage for your generator.

Match It Up

When selecting a generator, consider your appliances. The wattage you require for a window air conditioner is a minimum of 2,700 watts. A typical generator with 5,000 watts or more may be required if you want to utilize bigger appliances, such as a microwave.

Get A Wattage Estimate

Check the wattage on the back of your appliances to find out how much electricity they consume. Include any computers, televisions, or other equipment you may have.

Get The Right Voltage

Use the proper voltage Another crucial factor to consider when picking a wattage is the required voltage. Select a generator with 120 volts if you have appliances that require that voltage. Get a 240-volt generator if you have 240-volt appliances.


Before selecting a generator, it’s crucial to think about what you want to power. A lesser-watt generator can be adequate if you require the item for a brief period. However, it could be wiser to spend money on a sizable generator so you can power several appliances at once if you need to power them for prolonged periods.


How Should I Power Delicate Equipment Like A Computer?

For powering delicate devices, most manufacturers advise utilizing an inverter generator. The voltage generated by inverter generators is a “modified sine wave,” which seamlessly transitions between the + and – connections of the inverter.

What Kind Of Generator Should I Utilize For More Oversized Items, Such As A Microwave?

Standard “sine wave” voltage, which is what you typically receive from power companies, is produced by regular generators. This kind of generator is typically OK for more straightforward goods like a desktop computer. Still, it can harm or even kill delicate electronics. Because of this, most manufacturers advise using an inverter generator while using delicate items.

How Can I Be Sure That My Generator Is The Correct Size?

The wattage of your appliances is the best method to determine this. After that, figure out the generator’s wattage to ensure it satisfies your wattage needs. Before you go shopping, it would be helpful to note the wattage of your appliances.

How Much Electricity Is Used By A Window Air Conditioner?

A window air conditioner typically consumes between 1,500 and 2,700 watts. To divide the wattage, you might use two smaller units or one bigger unit.

Which Generator Size Is Required For My TV?

Estimate your TV’s wattage. An average-sized TV typically requires a 5,000-watt generator. However, a considerable TV may require a 10,000-watt generator since larger TVs use more watts.

What Is The Wattage Of A Microwave Oven?

A microwave typically consumes 1,200 to 1,500 watts of power. It is possible to utilize a more compact generator. Suppose you need to use the generator sometimes for a microwave supper. You could want a more significant generator with several thousand watts if you intend to use it for extended durations.
