Generators are useful in times of power outages. They are also useful during camping trips, outdoor excursions, or in the event of natural disasters like floods, hurricanes, or earthquakes. But generators that run on standard gasoline aren’t ideal for long-term use or large-scale emergencies because of their limited fuel supply. Inverter generator systems are a better alternative because they operate much more efficiently and on a wider variety of fuels.

Our Top Picks

TOP Choice #1 Westinghouse 4500 Watt Super Quiet Portable Inverter Generator
Our Score:
Westinghouse Outdoor Power Equipment

The iGen4500 can run for up to 18 hours on a 3.4-gallon gasoline tank, saving you from making many journeys to the gas station. The Push-Button Electric Start and wireless remote start are conveniently engineered for quick ignition. It is also ideal for operating delicate electronics like LCD/plasma televisions or mobile devices that need clean, consistent power because it has less than 3% THD.

However, the biggest downside of this product is when the temperature is too low, the machine is difficult to start, and sometimes the electric choke does not work correctly. Overall, due to its exceptional build quality, performance, and adaptability, we believe the Westinghouse 4500W is the most excellent inverter generator for use.

Champion Power Equipment

This product has a wireless remote key fob that can start and stop your generator up to 80 feet away. When the 4-gallon fuel tank is complete, the dependable 224cc Champion engine produces 4250 starting watts and 3500 running watts for 22 hours at 25% load.

This inverter features 23 feet at 64 dBA, is slightly louder than everyday speech, and has a 0.6-quart oil capacity and a low oil shut-off sensor. As the electrical load is lessened, it lowers engine speed, extending engine life and improving fuel efficiency. You need to operate this operator carefully because it can turn off unexpectedly if you do not follow the guide that comes with the machine.

When it comes to power, this compact generator is powered by a 79cc engine that can produce 2350 watts of surge power and around 1900 running watts. Although powerful, it is not intended for RVs, so consider it a home backup option instead.

Because it only weighs 39 pounds, the sleek and compact design makes it easier for the user to carry and store. When it comes to outlets, this generator has two three-prong 120V receptacles, one 12V DC receptacle, and two 5V USB ports. Furthermore, the build quality is entirely satisfactory, and WEN even provides a two-year warranty. This generator is quite loud compared with other generators, and there is some oil seepage from the bottom. 

One of the most intriguing aspects of this inverter generator is that it weighs only 50 pounds and has such a compact design that you will never feel awkward carrying it on trips. Despite its small size, the 79cc engine in this generator produces 1600 running watts and approximately 2000 starting watts, which is quite impressive.

In fact, the vibrations and noise are well-controlled, so they are not at all bothersome while running. With a tank capacity of 1.1 gallons, it has a runtime of approximately 7 hours on half-load. So, compared to other generators, the runtime is shorter, but not by much. 

This generator is built to last and has a solid design, making it one of the most premium offerings on the market. It is, in fact, tiny and light. That said, if you need a small generator for home backup, the Honda 662220 EU2200i 2200 Watt Portable Inverter Generator is a good choice. Its 121 cc engine is quite powerful, delivering approximately 2200 starting and 1800 running watts, which is impressive considering its small size.

This generator is parallel capable and includes a 0.95-gallon gasoline tank. With a full tank, this generator can run for up to 9.6 hours, depending on the load. It also has a DC 12V 8.3A outlet and dual 120V 15A household outlets on the back. Unfortunately, this model does not include any USB ports. On the other hand, Honda offers a three-year warranty on this generator to ensure customer satisfaction.

This is one of the best and most potent inverter generator options in the affordable category, with 2300 peak watts and 1800 running watts. Because an 80cc engine powers it, it is also very fuel-efficient and can provide backup for up to 8 hours with a 1.18-gallon tank capacity. It is also one of the lightest generator options, weighing only 47 pounds.

This generator features stable sine wave technology, which ensures the safety of all your connected devices, such as mobile phones, laptops, and other 120V small appliances. It isn't powerful enough to power an RV air conditioner, but it does include two household outlets, a 12V DC 8A outlet, and a 5V DC 1.5A USB outlet that will come in handy.

More To Consider

What to Look For in a most reliable inverter generator?

We're sure you've purchased something and afterward regretted it. We are all concerned about the items we purchase. The easiest method to prevent these concerns is to conduct a thorough study before purchasing the most reliable inverter generator.

That is also why we decided to introduce this post in order to provide you with advice on how to avoid buying errors when selecting the most reliable inverter generator.

Fuel Source

Generators are generally powered by either gasoline, natural gas or propane.
The majority of portable generators run on gasoline and can generally keep fridges and lights running for several hours. These generators can't be relied upon for long-term power backups, such as when there is no electricity for several days.
Propane and natural gas are used more often for large home-standby generators. These fuels can be used for larger home standby generators as they are cleaner-burning and offer on-demand power.
Solar or battery-powered power sources are an alternative to traditional fuel-powered generators. These machines have different capabilities, and their run time can vary widely. However, they might be the best match for you if your power requirements are less than minimal. They are typically used for camping only, not home.


A generator's wattage is the measure of its ability to provide power for whatever it plugs into. This information is crucial to understand about any generator that you are considering.
However, this number does not represent the entire picture. Wattage is made up of three parts: power needed to turn on an appliance and power required to maintain it running. It also includes power necessary to sustain a power surge, which is when regular juice returns to normal and all appliances start to work again. Many appliances use more power for startup than their run energy consumption. You could overload your generator when you turn on appliances and other devices. If the generator can't provide enough power, it could overload. You need to know how many watts your generator can generate, depending on whether it is powering just one item or the whole house.
An increase in generator costs is generally associated with a higher wattage. Most people agree that it's better to have enough power than not to be able to run your fridge or keep cool by a fan.


Installing home generators requires space. So make sure that you consider the dimensions of all models. You can find generators in a variety of sizes, from smaller units measuring less than 3ft to more large units measuring 5ft or more. A general rule of thumb is that the generator with the highest power rating will be larger.
Be aware that the clearance between your home and generator may be determined by local codes or model specifications. A small generator may require only 18 inches of clearance.

Automatic Start

Whole home generators can automatically start when power goes out. This allows the generator to automatically start supplying power when there is no electricity from the utility. This feature is usually only available on standby generators, and not portables. These systems can provide peace of mind and may be more expensive than the security that your generator will automatically turn on without interrupting vital systems like heating and cooling.


A warranty is usually included with the purchase of a generator. The warranty covers both labor and parts for most residential inverter and portable generators. For standby generators which can be larger investments, you will usually get a 3- to 52024 warranty period.
Certain warranties may also include travel expenses for technicians to visit the generator and fix it. However, this depends on which manufacturer you are using.


You need to decide which generator type is best for you: a portable or standby generator. This will help you decide if you just want the lights to stay on or if you need to power other electrical components such as the refrigerator, window, central air conditioner, and the fridge.


Can I Vent The Exhaust Out Of An Enclosed Area?

No. The generator should not be used in enclosed areas or homes. The portable generators can only be run outdoors where there is adequate ventilation. As with all gasoline engines exhaust, generators contain poisonous carbon monoxide.

How Do You Safely Run A Home Generator?

A whole-home generator or standby generator must be connected to a switch. This disconnects your circuit panel and the electrical grid, allowing power to flow through the circuits from the generator.
You must manually start the power transfer for portable generators. These products have different safety requirements.

Where Is The Best Place To Put Your Home Generator?

Natural gas generators do not produce as much fumes than natural gas ranges. Gasoline-powered generators can produce carbon monoxide exhaust fumes, which is why it's important to select the ideal location. These are the reasons why utility companies and local codes often have specific requirements for placement.
A generator should generally be located at least 5ft from any windows or doors. While some generators are able to be mounted as close as 18inches from the house, it is still important that the generator is at least 5ft away from any air intake areas on the property.
It is not advisable to use portable generators in an indoor environment, such as a garage. This type of generator is best placed outdoors, away from windows and doors.

What Regular Maintenance Should Be Performed On A Home Generator?

You should get basic maintenance information from the manufacturer of any generator that you buy. However, most generator models will work fine if you follow these guidelines.
Run the generator at least 30 minutes per month or perform a weekly self test
When storing a gasoline-powered generator, add fuel stabilizer.
Regular oil changes are a must for your generator.

Does The Portable Generator Need To Be Grounded?

Yes. It is important that the generator be correctly grounded in order to protect your safety. The generator must be grounded properly to avoid electrocution. Grounding is a subject matter that must be adhered to by all authorities, federal and state.

Can I Use The Generator During Inclement Weather?

Although you can use your generator in any weather or temperature, protect it from the elements whenever it is not being used to stop it from shorting out and rusting. It is not recommended to run the generator indoors.


Finally, the most reliable inverter generator may be readily used and offers a range of options to meet your needs. When looking for another kind of most reliable inverter generator, which we recommend  A-iPower Portable Inverter Generator, all of these characteristics are significant. 

We've combed through all of this data in order to assist you in making the best decision possible. Let us know if there's anything else we can do to help you discover the most reliable inverter generator in the comments section below!
