Types of Generators

There are different generators to choose from for your power needs. Each of the different types is unique in its mode of operation, built, and the fuel it requires. Understanding the types and how they function will help you in your quest to find the best portable generator on the market for your specific needs. Here are some of the most popular generator types and their properties.


Portable generators are light weight devices that run on gasoline, propane, or diesel and provide electricity up to a certain wattage level. They are usually used as an emergency power option at home during blackouts or short-term electricity needs on the job site or during outdoor events. There are also RV and camping generators that are used as a primary source of electricity off-grid. Users can have them connected to a home’s electrical panel or plug appliances directly into them. The market offers a multitude of generators of various power, size, weight, and a multitude of features.


Conventional generators are usually characterized by power surges that are particularly harmful to sensitive electronics. On the other hand, inverter generators convert the direct current into a smooth sine wave current. As a result, they produce more stable and clean alternating current (AC). Compared to a standard generator, an inverter generator will have lower total harmonic distortion levels. Therefore, it is safe to use with sensitive electronics and home appliances. In addition, inverter generators are usually lighter, quieter, and more fuel-efficient. You can learn more about the difference between inverters and generators in our dedicated article.


In contrast to a portable generator, which provides instant but temporary electricity, a standby generator is a more permanent backup solution. Standby generators, also referred to as whole house generators, are powered by liquid propane or natural gas. They are permanently installed and connected to the electrical panel using transfer switches. If the grid goes down they start automatically. They are usually used for whole-home needs and can run an entire house full of major appliances for days when necessary. Additionally, they are widely used in hospitals, factories, and other facilities. A professional electrician is needed to install standby generators safely. Learn more about the difference between portable and standby units in this guide.

Fuel Options

The type of fuel a generator can run on is a crucial feature. Depending on the fuel choice, a unit can be more or less fuel-efficient, eco-friendly, and reliable in emergency use. Here are the most common fuel types used by generators.


gas powered portable generators

Gas-powered generators are the most common type of generators, unlike diesel or propane. Gas-powered portable generators run on gasoline, which is cheap relative to other fuel types. They are fuel-efficient, and they come in various sizes and models, making them simple to transport. Additionally, gasoline is readily available, assuming the power grid is functioning. What is needed to run a fuel pump? Electricity. Ironically, during a blackout it can be impossible for your local gas station to provide gasoline. Therefore, you need to keep some on hand. However, bear in mind that gasoline is an unstable hydrocarbon and will decompose over time. It has a safe shelf life of about three months. The smart, albeit incovenient thing to do is to pour aging fuel into your car, then refill the containers with fresh fuel. The shelf life of gasoline can be extended by using fuel stabilizer which slows down the decomposition process.

As for other fuel types, propane is usually less expensive than gasoline and can be stored indefinitely. However, propane-powered generators are not ideal heavy duty use. The logistics required to install and store them are quite prohibitive. These fuel systems are also very complex and, therefore, are subject to frequent failures.

On the other hand, diesel has a longer shelf life than gasoline. However, diesel-powered generators are slightly more expensive. Moreover, the emissions of such engines are prohibitively high, and it is advisable to limit the amount of time you run these generators in a day for environmental protection.

portable dual fuel generators

Dual Fuel

Dual fuel generators run on either gasoline or propane. They function as units that use one fuel type. But with the added convenience of switching between fuels based on the user’s personal preferences, current needs, or availability. Dual fuel generators can save money since propane is usually cheaper. They are also more fuel-efficient when gasoline is used.

Finally, a dual fuel generator gives you the option and flexibility to choose, and this is always a good thing in emergencies when fuel is not always available.


electric generators

Solar generators trap the sun’s energy using solar panels and convert it into electrical energy. They work differently than a typical generator in that they receive the energy from a solar panel and store it in a battery bank (lithium-ion battery) for later use. They produce clean, free energy, and the fact that solar energy is a renewable resource means that you will hardly run out of ‘juice’ for your generator. Solar generators have no moving parts, which makes maintaining them a breeze. They can be used outdoors as well as indoors since they have no fumes or emissions.

When comparing solar to other fuel types, the total power produced by this passive generator is relatively low compared to other generators. Therefore, they are not ideal for running large appliances such as air conditioners unless you have a big enough solar setup.

Vital Buyers Guide to Find the Best Portable Generator

The history of generators goes a long way. Today, with such a wide range of options for generators, finding the perfect generator for your specific needs and budget is not a trivial task. Below, we have outlined what will help you choose a portable generator for your home emergency backup power or off-the-grid energy requirements. When you’re in the market for a portable generator, these are the points to make a note of to make the best purchase decision.

power requirements for outdoor generators


The amount of backup power supply you need is influenced primarily by the items you intend to use. Appliances are rated in their starting and running wattage. Starting watts are the power required to start up an appliance with a motor (e.g. a refrigerator). The running watts are what is needed to continue to use an appliance once it is up and running. The starting wattage rating is always larger than the running wattage. Keep this in mind when you select the portable generator is right for you.

As you estimate the amount of power that you will need, factor in all the applications you intend to use up and pick a generator size rated slightly higher than that figure just be on the safe side.

Run Time

Most generators indicate their run time at either quarter (25%) or half (50%) of the load. This represents how long it will run on a full fuel tank at the set percentage of its total power. If you intend to use a portable generator for emergencies and during blackouts, and then be sure to have enough fuel on hand to provide you with enough hours of runtime.

Noise Level

The operating noise level of portable generators depends on the manufacturer, model, and wattage. It usually ranges from 60 to 90 decibels, with inverter generators being the quietest generators on the market. For comparison, here are some examples of noise operation measured in decibels:

  • Whisper talking – 30 dB.
  • Operating refrigerator – 50 dB.
  • Vacuum cleaner – 70 dB.
  • Blender – 80 dB.

The acceptable range for generators is between 60 and 70 decibels measured from 23 feet away. At this level, you can comfortably hold a conversation and act less as a disturbance to your neighbors at home, on your business premises, or at the campsite.

Starting Methods

There are several methods of starting a generator. Some generators feature just one way to start. But in most cases, there are multiple options. Let’s look at the most common ways to start a portable generator.

  • Recoil Start: Another name for recoil start is manual or pull start. Generators with this starting method ignite by pulling the cord, which activates the internal mechanism to start the engine. Although more affordable, generators with recoil start are not for everyone, especially people with insufficient strength, shoulder/grip problems, or a disability.
  • Electric Start: This method removes the physical aspect of starting a generator completely. It allows you to run your generator by flipping a switch, pushing a button, or turning a key. In general, portable generators with electric start are slightly pricier. So it’s essential to weigh the pros and cons to determine whether the extra cost is worth it in your situation.
  • Remote Start: As the name suggests, portable generators with remote start are powered remotely. This works similarly to an electric start. But the user doesn’t have to be next to the generator when starting it. However, keep in mind that to start the generator remotely, it will have to be in the ‘Ready to Start’ state.

Power Outlets

When it comes to operating, controlling, and monitoring a generator, the control panel comes into play. A generator with several power outlets allows you to use your generator by spreading its load optimally. Most generators supply power like 120V, 240V AC, or 12V DC. Some models feature all three possibilities, while some supply only 120V AC. Also, having a transfer switch-ready outlet means that it allows a safe connection between your home’s wiring and the generator.

You can have various outlets such as 20 amp, 30 amp, and 50 amp, which you can use depending on the device or appliance you’re powering and the wattage you’ve chosen. Other generators also feature ground fault circuit interrupter or GFCI outlets, which is another safety feature that protects you from an electric shock.

Convenient Features

The best-rated portable generator you can pick should be simple to use and feature automatic control options that protect the generator from damage. For example, a low-oil shutdown feature turns the engine off when the oil level gets too low. A fuel gauge is handy to quickly check the remaining fuel. An hour meter tracks power usage, running time, fuel consumption, and ensures you know when maintenance time comes. In addition, a built-in co-monitor to detect high levels of carbon monoxide and automatically shut the generator off before it puts you in danger.


The weight of a generator is not necessarily tied to how much power it generates. But high power generators are usually a bit heavier. Therefore, wheels and handles make it feasible to move these types of generators around. Professional generators are usually heavier since they pack up more components and a larger fuel tank to generate all that power. However, if your home appliances don’t require a large power output, going for a compact portable generator will serve you better.


Generators that run on fossil fuels are the biggest culprits when it comes to emissions. This includes diesel and gasoline generators. If you are looking for a ‘green’ generator, then a solar generator or a portable power station may be ideal for you. Also, look for the exhaust compliance and certificates that the generator could obtain, such as EPA, CSA, or CARB. These certifications confirm that the portable generator meets specific regulations which ensure cleaner air and environmental protection.


Generators are expensive machines that could set you back a couple of thousands of dollars if they get damaged. For this reason, you should only buy a portable generator backed by a reliable generator brand with a long-term warranty from the manufacturer. This way, you can have your generator repaired or replaced in the event of a failure. An extended warranty also shows the manufacturer’s trust in their product. A good warranty is two or three years long. Read the warranty information carefully to know what is covered and what isn’t. And, keep in mind to never accept damaged goods.


The price of a generator is influenced by:

  • The amount of power it generates.
  • The ease of use features it has.
  • Its noise rating.
  • The brand manufacturer.

Generators from established brands will have a higher price because of the manufacturer’s experience in making these reliable engines to serve you for a very long time. You can be sure that they offer the best generators around.

Generator Safety & User Responsibility

The benefits and uses of generators are unlimited. But it’s essential to use generators safely and responsibly. Here are some points to keep in mind:

  • Firstly, generators are for outdoor use only. This means it’s unsafe to have them enclosed in your home or garage because of carbon monoxide emissions.
  • Additionally, you need to set up far enough from your home, windows, and ventilation. Allow a distance of at least 20 feet to avoid the danger of carbon monoxide poisoning.
  • Further, installing a CO detector (carbon monoxide sensor) is an excellent way to ensure safety.
  • Learn how to use your generator safely so that you can stop it quickly in case of an emergency.
  • Moreover, understand all your generator controls, output receptacles, connections, extension cords, and various generator accessories.
  • Store your electric generator in a dry and cool place when not used. And shield it from rain, snow, and other weather conditions. You can use a generator cover or a GenTent to protect it from wet conditions.
  • Also, store the fuel in a safe space and proper containers.
  • Finally, protect the environment and others by responsibly disposing used motor oil. Never pour the oil down the drain or throw it in a trash can.
