This article is about answering your question: what will a 7000 watt generator run?

In case you’re wondering just how many appliances a 7000-W generator will run, you’d be surprised to discover that it can run your house lights, refrigerator, and much more. 

In other words, a 7000 Watts generator is enough to see you through a prolonged outage, should one occur. So the key to running as many appliances as you want when there’s a disruption in the regular power supply is to pick out a good-quality generator. 

While most people tend to consider 7500 Watts generators to be ideal for homeowners, a 7000-W one would be adequate to see you through an emergency, provided you know how to use it well. 

I’ll take you through how you can use a 7000-W generator to power your appliances in the following sections. 

What Will A 7000 Watt Generator Run? Factors To Consider

When determining whether or not a generator can run your appliances and what appliances it will run, you’ll first need to take a few basic factors into account. I’ve outlined these factors for you below. 

Power Calculation 

To understand how long your generator can run for and how much load it can take, you’ll need first to determine how many watts each of your appliances will add up to. 

You’ll need to add the start-up watts and see if these exceed 7000 watts. If they do, then you might overload the generator. 

However, overloading your generator doesn’t mean that you can’t use it anymore. Instead, it means you can only run the appliances that take up less than 7000 watts in total. 

In other words, you’ll need to switch off the appliances that take up more power and only use those that are essential – such as the lights and fans. 

Other appliances such as refrigerators and air conditioners take up more power, and using them during an outage shouldn’t be a priority if you can help it. 

Besides, it’s important to take into account that you can never be completely sure of how much power all your appliances will add up to. Therefore, it’s always useful to have a set margin for uncertainty, usually around 10%. 

Area And Requirement 

The power output capacity of the generator you purchase should also depend on your house’s area and your specific requirements. 

Broadly speaking, a 7000-W generator should be enough to power a house that’s approximately 3000 sq. feet large. Moreover, you’ll need to consider the length of time of the power outages you usually face before purchasing a generator. 

The length of time of power outages usually depends on the weather and time of year. However, several areas across the country face outages and blackouts in stormy weather, and so those living in these areas should consider purchasing a generator

Depending on how long you’ll be without a power supply from the grid, you’ll need to decide which appliances you’ll need to work in your house. 

Generators should be placed outside the house mainly because they can fill your house with toxic fumes that are a great health hazard. In addition, most people tend to keep their lights, ceiling fans, refrigerators, and water pumps on during an outage. 

A water pump is required to prevent flooding (especially in houses with basements), and you may need to keep your refrigerator running in case there’s food in there that might spoil. 

Most household appliances require 240 or 120 volts to function, which should give you an idea of how much power each of your appliances takes up and use them during a blackout accordingly. Avoid using appliances that take up more power (such as water heaters and air conditioners) if you can do without them. 

Power Output 

We spoke about power calculation and requirements, not let’s discuss how you can measure power output. When it comes to generators, power is measured in terms of watts. 

To determine how much power your appliances require to run, you’ll need to multiply their voltage requirements with the amperes. 

Most appliances use voltage, while some could feature voltage amperes (VA). Depending on the voltage of the appliance, you’ll need fewer or more amperes to run them.

However, bear in mind that the power or wattage matters, not the voltage, when it comes to using a generator. 

The Best 7000 Watt Generators On The Market Right Now

This section will take you through some product reviews of the best 7000 Watt generators I could find online. 

A-iPower SUA7000C 7000-W Gas Powered Portable Generator 

This portable generator comes complete with wheels and is specially designed to power tools on construction sites. Its functionality and durability are apparent in the sturdy design of the generator. 

However, this generator is not useful around construction sites alone; several homeowners use it to power their appliances during a power outage as well. 

What I thought to be the best feature of this generator is that it’s very easy to move around, with its sturdy wheels and folding handle. As a result, it looks more like a mini shopping cart or stroller than a generator, making it aesthetically pleasing. 

However, that’s not important. What’s important is that it contains a 7-gallon large tank for gasoline that could run your appliances for either 8 or 12 hours, depending on how many of them you use at a time and the power requirements of each. 

The engine of this generator is one of the most powerful ones I’ve come across for a 7000-W model being 389 ccs. What’s more – the engine alerts you when the oil is running low with the help of small light and shuts down automatically when the fuel is running low.

Briggs And Stratton ELITE7000 7000—W Portable Generator 

This portable generator features a futuristic design and comes complete with a CO guard and electric ignition. The engine of this generator is extremely powerful at 420 ccs and is known for using up fuel efficiency to provide you with as much power as you need in case of emergencies. 

Using this generator is quite simple as well since it features a control panel that displays all relevant information. The control panel also has protection from circuit breaks, making it one of the safest generators in the market. 

Most of those who have used this generator claim that it makes a significant amount of noise, but this won’t matter if you don’t place it right outside your bedroom or living room window. The fuel tank has a 7-gallon capacity that you’ll find adequate to see you through a prolonged blackout or outage. 

Besides, you’ll find that not having to refuel the generator very often will save a great deal of time and effort in the long run. The wheels of this generator are large and well-designed as well, which makes it easier to transport it across some difficult terrains.

Craftsman 7000-W Portable Generator By Briggs And Stratton 

This generator can run between 7000 and 10500 starting watts, allowing you to use pretty much any appliance you want during a prolonged power outage. Besides, this generator is very easy to use, and you don’t require any technical skills or expertise to be able to use it. 

For instance, starting it is pretty easy as it features an electrical starting system that responds to the touch of a button. The engine built inside the generator is more than just a little powerful at 420 ccs. This engine is long-lasting and can last for nearly 12 hours running several appliances during an outage. 

What I found to be the best feature of this generator is that it features a large fuel tank that can hold no less than 8.5 liters of fuel at a time. This is mainly why this generator can last up to 12 hours when not fully loaded. 

This portable generator is very easy to maneuver as well with its well-rounded wheels and a handle that you can fold when you don’t need to move it.

Is A 7000-W Generator Enough?

Yes, a 7000-W generator is more than enough when it comes to powering a household of essential appliances to see you through an emergency or disruption in the power supply. 

Sure, these generators may not be able to power all the appliances in your house at once or those appliances that require more power, but they can power the appliances you need.

Lights, fans, air conditioners, water pumps, and even air conditioners can be up and running during a power cut with the help of these generators. Moreover, for an average-sized home (less than 3000 sq. feet), a 7000-W generator should more than suffice during a power outage. 


To conclude, a 7000-W generator can power up most household appliances that you’ll need during an outage and lasts for anywhere between 8-12 hours, depending on which appliances you use.
