Top 6 best portable gas generator for home use

You’ve heard about these things before, but now they’re finally within reach. Portable generators are becoming more affordable, efficient, and reliable. They’re also easier to operate than ever before. Are portable generators really worth their higher price tag?

Portable generators are compact devices designed to provide emergency power for homes or businesses. These units are typically powered by gasoline engines, diesel engines, or electric motors. The size of a portable generator depends on its intended purpose. For example, a large unit might be able to power several buildings at once. Smaller models are usually built to run only one building.

Portable generators are great for providing backup power during emergencies such as hurricanes, tornadoes, floods, or other natural disasters. If you live in an area prone to power outages, a portable generator can come in handy. It’s especially useful if your main source of electricity is gone. A portable generator will allow you to continue operating essential appliances like refrigerators, freezers, air conditioners, and computers.

If you need additional electrical outlets, a portable generator may not be the best option. Most portable generators have very limited output, so it won’t be possible to add any extra outlets without purchasing a separate device. However, some models do include multiple outlets.

If you plan to use a portable generator to charge cell phones, laptops, tablets, or other electronic equipment, make sure that the model has enough capacity to handle all of your gadgets. Some models don’t have enough battery storage to keep up with high-powered electronics.

How Does a Portable Generator Work?

A portable generator works by converting mechanical energy into electrical energy. It does this using either a combustion engine or an alternator. In most cases, the engine drives a belt that connects the alternator to the motor.

The engine converts fuel into heat, which turns a turbine inside the alternator. This spinning shaft creates electricity. The amount of electricity produced depends on how much fuel was burned.

The advantage of a portable generator over a standard wall outlet is that it provides continuous power. A conventional outlet requires a steady stream of current from the utility company. When there’s no power coming through the wires, the outlet goes dead. With a portable generator, however, you’ll always have access to electricity.

The essentials of home generators

It’s important to think about how and where you’ll use a generator before buying one. Using them in residential homes, with homeowners associations, at campgrounds, or on construction sites is often subject to laws, rules, and restrictions.

If you choose the right one, you’ll be able to power up your appliances or equipment. By picking the wrong generator, or using it improperly, you could damage it or what’s connected to it, at best. At worst, you could be exposed to fire, electrocution, or carbon monoxide poisoning.

How To choose the best portable gas generator for home use?

Portable generators are useful tools for emergency situations when power outages occur. They provide reliable backup power for homes, businesses, campsites, boats, RV parks, etc.

In addition to being able to run appliances like refrigerators, air conditioners, lights, fans, computers, televisions, cell phones, and so forth, portable generators also come equipped with a number of features that make them much safer than standard gasoline powered generators. These features include automatic shut-down after running for a certain amount of time, battery charging systems, and emergency lighting.

Today, we’ll discuss some of the different types of portable gas generators available on the market and explain how to choose the right model for your needs.

1. Portable Gas Generators vs. Standby Generators

Standby generators are typically larger units that require regular maintenance, but they’re very convenient for camping trips, tailgating parties, and outdoor events. However, these models aren’t suitable for residential applications due to their size. On the other hand, portable generators are smaller units that are easier to transport and store. They may not be as powerful as standbys, but they’re still capable of powering small appliances and providing light during emergencies.

2. Types of Portable Generators

There are several types of portable generators on the market today including diesel, natural gas, propane, and kerosene. Each type provides its own set of advantages and disadvantages, so choosing the right one depends on your specific application.

For instance, diesel engines produce the highest levels of torque, making them well suited for heavy duty tasks like commercial construction sites. Natural gas engines offer the lowest noise level, but they must be refueled every 3 months. Propane and kerosene generators are inexpensive and easy to install, but they require periodic maintenance.

3. Fuel Type

Diesel fuel is commonly used in portable generators because it produces high levels of torque, meaning that they can easily pull large loads. Diesel engines are also durable and last longer than other engine types. Unfortunately, diesel engines tend to emit harmful exhaust fumes, so they’re not recommended for indoor use.

Natural gas engines produce low amounts of pollution, but they require frequent refueling. Propane and kero­senes engines are cheaper and easier to maintain than diesel engines, but they only produce medium levels of torque.

4. Battery Size

Battery sizes range from 1/4 horsepower to 5 horsepower, depending on the type of generator. Smaller batteries are generally lighter, but they won’t produce as much power as bigger ones. Larger batteries usually cost more, but they’re stronger and more efficient.

5. Power Output

Power output ranges from 500 watts to 2,000 watts, depending on the type and brand of generator. Generally speaking, higher wattage ratings mean that the generator will be able to handle heavier loads.

6. Safety Features

All portable generators feature safety mechanisms that automatically turn off the unit after a specified period of time. Some generators even include automatic shut-downs when the battery charge drops below a certain point. Others are equipped with emergency lighting that shines brightly in dark areas. Finally, all portable generators feature ventilation systems that prevent carbon monoxide poisoning.

7. Warranty

Warranties vary by manufacturer, but most manufacturers provide at least a 1 year warranty. In addition, some companies offer extended warranties for up to 10 years or more.

8. Installation Options

Most portable generators come preassembled, but you’ll need to purchase an extension cord if you want to plug it into an outlet. Most generators have wheels that make transportation easier, but you’llneed a dolly if you plan to move the generator across a lot of uneven terrain.

9. Maintenance Requirements

Most portable generators require routine maintenance to keep them running efficiently. You should check the oil level regularly, replace worn parts, and clean out any debris that may clog the filter system.

10. Noise Level

Noise levels range from very quiet (less than 50 decibels) to extremely loud (over 90 decibels). The lower the decibel rating, the quieter the generator will run.

11. Price Range

The price range for portable generators varies widely, ranging from $300 to over $2000. Prices typically increase with each additional feature offered.

There are several types of generators

STANDBY

A standby generator is permanently installed and connected to a home. During a power outage, these systems may power selected, critical circuits, or they may provide power for the entire house. Generators with standby power monitor utility power and automatically start in the event of a power outage.

Inverter Generators

Despite the fact that inverter-type generators are typically portable, we separate them out because their operation differs significantly from the other two. Inverter generators provide 120/240 volts of AC power like most generators.

Just like the others, they generate AC current, but then convert it to DC (Direct Current), and then reverse the process. Inversion and conversion are controlled by circuitry that flattens surges and cleans up the sine wave (or oscillating wave) of electrical current.

Typical generators produce alternating currents with varying degrees of distortion. Generally, this isn’t an issue for most electrical devices, although sensitive electronics like tablets, laptops, televisions, and other smart devices can be damaged by current distortion or surges. With “clean” power and steady voltage, these devices will last longer. Inverter generators are typically more expensive due to their added complexity.

Portable

When and where power is needed, portable generators, also called backup generators, provide temporary power. Some are more portable than others; portable is a relative term. Smaller models can be picked up and carried, but most have wheels and handles to facilitate transport. It may take two people to load or move them since they weigh over 100 pounds.

On the generator’s front panel, standard outlets are available for plugging in appliances, power tools, or other devices. In addition, many models are equipped with twist-lock plugs that can supply up to 240 volts and can be used to power circuits in a home.

Fuel Options

Gasoline is the most commonly available fuel for portable generators. There are, however, a few issues to consider when using generators for emergency power.

One is that local gas stations may have trouble meeting demand when big, catastrophic storms strike and power outages last days. Second, backup generators are rarely used and may sit for months to years before being used again.

The gummy deposits left in a carburetor by gasoline slowly evaporate over time, making it difficult and even impossible to start the car without a service. By turning off the fuel valve and letting the generator run until it stalls, the fuel left in the carburetor can be used up.

The combustibility of gasoline can decrease over time as it oxidizes or goes “stale.” Water can also be absorbed by gasoline, corroding fuel tanks, and other metal components. These issues can be combated by starting a generator regularly and treating the fuel with a stabilizer.

Dual-fuel generators can run on gasoline or liquified petroleum gas (LPG), also known as propane. Fuel switching is simple, and you won’t be restricted to one type of fuel. One of the biggest advantages of propane is that it is very stable when stored for long periods of time.

Sitting on it won’t cause carburetors to gum up, and it won’t go stale. Also, some homes that use propane for other purposes may already have large storage tanks on-site, minimizing the need for frequent fuel trips.

One disadvantage of propane is that it has fewer BTUs (British Thermal Units, a measurement of energy) than gasoline. A generator that runs on propane will have lower starting and running watts, but will also be quieter than one that runs on gasoline.

Many popular generators can also be converted to run on propane with kits available. Natural gas can also be used in some kits. Prices vary depending on the application, but they begin at around $50.

Does a generator need to be grounded?

You’ll need a professional to pull the necessary permits and perform the installation if you decide to install a permanently installed standby generator. Since all standby generators must comply with local ordinances and/or the National Electrical Code, they will ground it.

Portable generators don’t need to be grounded if they are powered by plugging them directly into the standard outlets on the front of the generator to power appliances, tools, or other devices. Maybe if you’re using the generator to power circuits in your house.

Your local building officials can provide you with information on the city ordinances, the operator’s manual, and/or licensed electricians. Some localities may have requirements that differ from those in the NEC (National Electric Code).

Electrical circuits need to be grounded in order to operate electrical devices safely so that any current that shorts out or has a fault is directed to the ground, i.e. the actual, literal earth so that the user does not become a conduit to the ground. Generators can be grounded in two ways: bonded neutrals and floating neutrals.

In neutral bonded generators, the neutral wire is connected to the frame of the generator. There is no connection between the frame and the neutral when the neutral is floating. A grounding rod driven into the ground should be connected to the generator’s ground terminal in the latter case.

Generators with GFCI (Ground Fault Circuit Interrupter) outlets must be grounded by connecting the ground terminal to a ground rod, and driven into the ground when they are used to power circuits in your home. In addition to neutral switching transfer switches, three pole transfer switches are also known as neutral switching transfer switches.

How To Use a Portable Gas GeneratorSafely and Effectively

The best way to start a portable generator is to turn it off before disconnecting anything else. If you do this, then there won’t be any electricity flowing through the circuit breaker panel, which could trip the breaker.

If you want to run an appliance while the generator is running, make sure the generator is plugged into a dedicated outlet. This means that the generator can not be plugged into another outlet, such as one in the kitchen or bathroom, because this would cause a short circuit.

If you plan to run appliances while the generator is running and you don’t know how to properly connect the generator to the receptacles, contact a qualified electrician. You can find these professionals at your local hardware store, utility company, or online.

To prevent damage to the equipment, never leave the generator unattended. The exhaust vent should always be open, and the fuel tank filled to capacity. Do not allow children to play near the generator.

When operating a generator, be aware of its noise level. Keep the engine idle until the generator is turned off. It will produce more noise than normal operations.

When working around a generator, wear protective clothing and safety glasses. Never work without hearing protection.

Never attempt to service a generator yourself. Only a trained professional should perform maintenance or repairs.

Always read the owner’s manual thoroughly before starting up your generator. Follow all instructions carefully.

Before starting up a generator, check the oil level. Check the air filter regularly.

Do not use a portable generator indoors unless it has been tested and certified by Underwriters Laboratories (UL).

Be careful if using a portable generator outdoors. Always have someone nearby who knows what he or she is doing.

Use only approved extension cords. Never use a cord longer than 50 feet.

Keep the generator away from water.

Before starting the generator, unplug all other electrical devices.

Make sure the battery terminals are clean and free of corrosion.

Generator Safety

As with grounding, a professional will install your permanent standby generator according to code and at the appropriate distance from all windows, doors, and openings. In this way, carbon monoxide (CO, an odorless, colorless gas in exhaust that can poison and kill people) can’t build up to dangerous levels as it would in an enclosed space or under a window.

It is never a good idea to operate a portable generator or anything with a fuel-powered engine in a closed space, such as a garage or shed. Most manufacturers offer models that shut down when they detect carbon monoxide, which prevents them from running in enclosed spaces.

Running a generator in the garage, with the door open, or in front of the garage with the door open is not recommended – carbon monoxide can still be trapped in the garage and slowly seep into the house.

Due to this, generators should be run outside, at least 20 feet from the house, away from windows and doors, and with exhaust blowing away from the house.

How we tested and selected these generators?

To select these generators, we reviewed popular features, reviewed consumer reviews, and spoke with product engineers. While we haven’t tested the standby models, we recommend them based on our experience using and reviewing similar generators, research into the market, and feedback from customers. Your needs may be met by their price, design, or features.

The portable and inverter models were tested based on our experience using generators for backup power with and without transfer switches, on construction sites to run power tools and equipment, as well as operating sound systems and lighting at outdoor events.

A 2 foot and 25 foot distance was used to measure the sound level of these generators while they were idling with no load, as well as when they were running under load.

In order to observe the sine wave of the AC current generated by these machines, we used an oscilloscope, and to measure the voltage output, we used a clamp meter. Among the devices we used with large starting and running loads were a large air conditioner and a portable table saw.

In order to select the best generators, we evaluated their ease of starting, power response, sound levels, value, safety, and reliability. Additionally, we included three untested models that may meet your needs based on their price, design, or other features.
