A portable electric generator may be a lifesaver in a crisis and a great boon to everyday comfort when you're far from the power grid. Because electricity is integral to our everyday lives, a loss of power may seem more than just an annoyance when it really affects us—no heat or electricity from appliances. Non-functional medical equipment includes CPAP machines. What's worse is that I can't even go online since my house is without electricity. Whole-house electric generators are available. The R.V.'s appliances may be kept running by a modest generator. And portable, battery-operated charging stations ensure that laptops and floor lights stay lit all night long in the house. If you're ever in a power outage, an emergency generator may give you the flexibility to get by. In the event of a hurricane, you may utilize one to protect yourself from the elements. When camping or attending a tailgate party, one is a useful accessory. Using the greatest electric generator, an outdoor celebration may carry on strong into the night.


If you are in the market for an electric generator, then you have come to the right place. This comprehensive guide will teach you everything you need to know about how to buy the best electric generators for home in 2023. We will cover a wide range of topics, including the different types of generators available, the features to look for, and the brands that we recommend. By the time you finish reading this guide, you will be equipped with all of the knowledge you need to make an informed decision about which generator is right for you.

1. Is A Gas-Powered Generator More Practical, Or Would A Generator That Runs Off Batteries Work?

Gas-powered generators are sometimes bulky and loud, but they provide substantial power. It's no simple feat for these lumbering giants to convert fuel into light that can be dimmed. Large gas generators are installed to power a whole home in the event of a power outage, and they can reliably provide emergency power. Some models are designed to connect directly to your house's electrical system. However, expert installation is usually required for whole-house generators, and they are not inexpensive. Portable gas generators can keep essentials like refrigerators and air conditioners operating during power outages, but they need to be vented outside since they release carbon monoxide. (Never use them indoors, not even in an open garage.)

Electric generators that employ batteries are often referred to as power stations despite the fact that they do not generate energy but rather store it. Their popularity is skyrocketing. These generators can power essential electronics like phones and laptops but not power-hungry equipment like refrigerators and washing machines. Compared to gas-powered alternatives, they are more convenient in several ways: they are less expensive, less bulky, and easier to transport. They are also safe for use inside the house.

A portable electric power station powered by a rechargeable battery is the optimal choice if all you need is a means of charging devices and maintaining contact with the outside world.

Appreciating the Importance of Knowing the Rated Power of Your Backup Generator

Even the most basic generator has a bewildering assortment of numbers and symbols on its data plate. Running and surge wattage, or beginning wattage, are the two figures to check.

The amount of electricity required to keep an appliance operational is called its "running wattage." Since most electronics need a little additional charge to begin going, the generator will display a starting wattage to indicate how much juice you'll need to get things rolling.

A whole-house generator might need as much as an 8,000-watt generator. All but the most power-hungry gadgets will be able to function with this. A 100-watt generator won't cut if you need it to charge electronics, but you may get by with less.

Create a list of the essential home electronics and equipment you'd want to keep functioning in the event of a power outage. To get a ballpark estimate of the required watts, use this. Choose a more robust generator to give yourself plenty of leeway.

Many portable generators will include a wattage and hourly output breakdown (Wh). A generator with a 200Wh rating can power a 20W gadget for 10 hours. The generator must be fully charged in order for the mentioned specifications to apply.

Choose the most effective electrical generator by considering its charging time and fuel.

The charging time of a battery-powered electric generator is more crucial than the power output. It is possible to recharge the batteries of many power stations by plugging them into an electrical socket, a car's cigarette lighter, or the sun. It may take some time since a 160-watt battery requires at least five hours of continuous AC-wall-outlet electricity for a full charge. However, there won't be a spare five hours when calamity comes. If you choose a generator that runs on batteries, be sure to keep the charging station topped out regularly. Even more, time is needed for solar-powered generators. Think things through.

Gasoline is an obvious need for gas generators. Although many will run on regular gas, propane tanks have a far longer lifespan. The natural gas line is a reliable source of electricity for whole-house generators and certain portable gas generators. Natural gas generators are more economical and less harmful to the environment than their gasoline counterparts. You should store up on whatever fuel source you utilize and be prepared for any weather.

2. How portable are electric generators, anyway?

The gas generator may still need considerable physical force to move even though it is marketed as portable. Even with wheels and handles, these gas generators may weigh hundreds of pounds, making them difficult to transport on camping excursions.

Energy stations that run on batteries are significantly easier to transport since they weigh less than 20 pounds each. Some portable generators may provide enough power to recharge a phone almost 10 times and weigh as little as two pounds.

A power inverter is explained, along with its uses.


An inverter generator works by first converting direct current to alternating current and then back to direct current. What's with all the circling? Put, inverting the power from D.C. to A.C. and back to D.C. will result in more constant and efficient electricity. Such a solution is perfect for laptops and other delicate electrical devices. High-tech equipment is particularly vulnerable to damage from power fluctuations and surges. An inverter generator's safe electrical output comes from its clean design. As a negative, inverter generators are more expensive than regular gas generators. However, they are more efficient and less noisy than gas generators, making the investment potentially worthwhile.

Finally, gas generator noise levels are an important metric to consider. Outdoor events may be ruined by noisy generators that emit noise at 90 dB or more. Battery-powered energy stations are quieter than gas generators since they don't have engines.

Understanding Backup Power Systems for Your House

It would be best if you gave some thought to where and when you may need a generator before rushing out to acquire one. The usage of these devices is generally governed by a number of rules and regulations, whether in a domestic setting, a homeowners' association, a campground, or a building site. It's important to get the proper one so that you can run the necessary electronics and machinery. If you choose poorly or misuse it, you run the risk of damaging the generator or the equipment you have attached to it, or even worse; you run the risk of fire, electrocution, or carbon monoxide poisoning.

3. Where to Find the Best Generator

The size of your home and the appliances you want to run are the two most important factors to consider when selecting a generator. Only the most essential home appliances (like the refrigerator, heating system, and water heater) will typically require the minimum 5,000 to 7,500 watts required to power a typical residence. There are alternatives for portable home generators that can get you through an outage and permanent installations that can power your whole house. If you need continuous electricity, you should choose a generator with at least 20,000 watts of power. This is especially true for those with very big houses or families who consume more energy than a family of two or three.

It's also worth remembering that generators are a substantial investment, but they will last for many years. Depending on the model, a home standby generator can provide power anywhere from 10 to 30 thousand hours. A ten- to thirty-year lifespan is implied by annual usage of 100 hours.

Methods Used to Evaluate and Choose the Selected Generators

In order to decide on these generators, we read popular features, combed through customer reviews, and consulted with product engineers. Even if we have yet to try out the standby models ourselves, we've included them in our recommendations after considering our prior work with and research into comparable generators, as well as feedback from actual consumers who have purchased from the merchants in question. They may fit your requirements well because of their attractive pricing, style, or features.

We put the portable and inverter versions through their paces by drawing on our background utilizing generators for backup power (both with and without transfer switches), on building sites to power tools and equipment, and at outdoor events to power audio and lights. We tested the noise produced by these generators at two and twenty-five feet away when idling and while operating at full capacity. We monitored the A.C. current produced by these devices using an oscilloscope and verified the output voltage using a clamp meter. We also employed enormous air conditioners and portable table saws with significant beginning and operating loads. We chose the best models based on how simple they were to start, how quickly they gained full power, how loud they were, how much they cost, how safe they were, and how reliable they were. We have listed three models that have yet to be thoroughly evaluated but which may suit your requirements because of their attractive pricing, design, or other characteristics.

4. The Four Primary Generating Units

While we've narrowed down on home backup generators for this rundown, there are really four distinct types of generators on the market today.

Automatic backup power systems

As described above, home backup generators are permanent systems that kick on automatically in the event of a blackout. It is unnecessary to worry about whether or not your generator is ready for the next outage since these sophisticated machines are programmed to activate even in the absence of electricity and to test and self-diagnose continuously. Propane, the fuel source for home backup generators, is more secure than gasoline for long-term storage.

Natural gas from your gas line may be used to power these appliances, providing an endless supply. These generators may cost anywhere from $6,000 to $11,000, not including installation. They can produce anything from 5,000 to 520,000 watts.

Portable power generators

Thanks to the device's namesake, there's no mistaking what a portable generator's intended use is. There is a wide range of power and size for portable generators. Depending on their size and power, these generators will cost anywhere from $500 to $2,000.

Carbon monoxide emissions from portable generators may be fatal in confined places. Thus they should never be used inside or near air conditioners or open windows. Standard gasoline is the fuel of choice for portable generators because it is cheap and readily available, although it is difficult to store for extended periods of time.

Affirmative: Inverter-Based Power Sources

Power output-wise, inverter generators are comparable to conventional portable generators, but they use a fraction of the fuel. They tend to be less noisy and less polluting. However, the pricing is greater because of these extras, with most models going for between $1,400 and $4,000. Due to its capacity to automatically throttle up or down to fit the power demand rather than operating at full intensity all the time, inverter generators may be significantly quieter than portable generators.

These units include smarter exhaust systems that are meant to reduce noise levels.

Power Generators That Can Be Moved Around

A more recent addition to the market, portable power stations, is made feasible by the decreasing cost of high-capacity batteries. Instead of using fossil fuels like propane or gas, these generators may be charged with the standard household current or solar panels. Because they don't release harmful byproducts, portable power stations are safe to use anywhere, even within a house or apartment.

Portable power stations have one key drawback: their cost per watt is sometimes much greater than that of standard portable generators. It may be challenging to utilize these power stations for an extended period of time during a blackout since they must be charged by plug-in or solar. Portable power stations are an excellent alternative for tailgating and providing electricity to essential gadgets and appliances during a temporary blackout.

5. Powering Your Home: How to Choose a Generator

The power needs of your house and your most important major electric appliances should be calculated before you purchase a generator. The most important and power-hungry appliances to keep running during a blackout are likely to be refrigerators, air conditioners, sump or well pumps, medical equipment, electric water heaters, and portable space heaters.

If you need help determining what size generator would be suitable for your house, you may use one of the many online wattage calculators offered by generator manufacturers. You can also figure this out by checking the wattage ratings of all of your major home gadgets. Many appliances will clearly mark the "starting watts" and "running watts." As the name implies, the former refers to the power used by an appliance when it is initially turned on, while the latter describes the power consumption when the equipment is really operating.

In general, if the beginning watts are not specified, they may be calculated by tripling the running watts. To ensure that your home is safe, add up the initial wattage of all your appliances and multiply that by 1.5. Many generators supplied in the United States have 7,500-10,000-watt outputs since this is the minimum power needed for a modest to medium-sized home.

Scale and Discord

After determining your electrical requirements, think about the size and noise level of the generator. Whether you have a little front yard or a sprawling estate, you'll still need to keep the generator somewhat close to your house because of the noise it makes.

Our largest generators are about 30 by 30 by 48 inches, while the smallest ones are closer to 24 by 24 by 36 inches. Generators must be kept at least five feet away from any kind of opening, as stipulated by the National Fire Protection Association's (NFPA) regulation.

Local building rules may vary from NFPA standards, but generally speaking, a house generator just has to be placed at least 18 inches from an outside wall.

You should also think about the decibel level of the noise the generator would make if it is situated just outside your house (dB). For comparison, a standard vacuum cleaner emits noise between 70 and 80 DBS, whereas the majority of the generators on our list have a noise level between 60 and 70 DBS.

Modifications to the Fuel Type

All the home generators we've included on this list work on either liquid propane (L.P.), natural gas (N.G.), or both. Those that are biofuel are readily converted to burn any fuel with no special equipment required.

Propane's benefits include low cost and a "cleaner burn," which means it produces fewer byproducts and less pollution. Propane is sold in smaller canisters in grocery shops, lumber stores, and petrol stations, in addition to the larger tanks in some homes.

Natural gas-powered generators may be hardwired into a home's existing natural gas line, providing an endless supply of fuel. Natural gas has two major drawbacks: it is less efficient than propane, so it generates less power, and the generator still has to be connected to the gas grid in case the electricity goes out.

Here Are Four Good Excuses to Buy a Standby Power Supply for Your House

Electric Ignition

Unlike portable generators, residential generators are always ready to go when the power goes out. Many of them can even start by themselves if they detect a power drain at the electrical panel. A house generator's remote start is far more convenient than a portable generator's pull cord, even if it doesn't start immediately.

Interruption-Free Transfer Switch with Automatic Reboot

The use of an Automatic Transfer Switch is required for any home generator with a power output greater than 5,000 watts (ATS). In the event of a power outage, the ATS will immediately switch your home's electrical panel from grid power to the backup generator (this is also what can trigger some generators to start automatically).

The ATS prevents your generator from unintentionally sending electricity into the city's grid. The manual transfer switch used by most home generators with an output below 5,000 watts and most portable generators is inconvenient.

Capacity for Producing Electrical Energy Is Enhanced

Residential generators can often power a full house since they have the highest power output of any non-industrial generator. Home generators often range from 10,000 to 50,000 watts, or even more, but portable generators typically average between 3,500 and 10,000 watts.

A house generator's greater power capacity provides you peace of mind when the electricity goes out. You can keep everything you need running since the typical U.S. home requires a minimum of 5,000 to 7,500 watts for vital equipment. It's possible that you may even assist your neighbors in getting electricity.

Fixedly Positioned

Permanently positioned outside your house, generators may provide instantaneous backup power in the event of a blackout thanks to convenient features like automated transfer switches and electric starters. A portable generator can be moved from the garage to its working location, where an extension cord is attached to it, and the generator is started by pulling a cord.

In addition, most residential generators are powered by liquid propane and or natural gas, which may be permanently connected to your generator to eliminate the need for refueling.


The optimum power source will be robust and reliable while also being highly effective. Depending on your needs, you'll want to choose between several sizes and styles of electric generators. Large gas-powered generators are ideal for use with heavy-duty equipment. Stationary power sources are ideal for portable electronics. Even better, whole-house natural gas generators ensure your family can continue living comfortably even if the power goes out. You should maintain the gasoline tank or battery fully charged in any generator or power source you use so that it is always ready to go when you need it. As long as it is put to good use, even the greatest electric generator may be a potent tool.
