Best Portable Generator 2023 Buying Guide

Electricity has become one of the peculiar things in our day to day life, and it has almost become impossible to live without it. Today, in the digital world, where everything works upon the electricity, a power outage can not only create hindrance in our work but can also, virtually, cease our life. In order to, not let the power outage create a barrier in our life, electricity storage units were made. These electricity units were called generators which converted the mechanical energy, acquired from an external source to electrical energy. Generators became the go-to solution for people facing trouble because of the electricity shortage or power cut.

Though useful, the original generators were very bulkier, and it was a task to get them to a start. With the developing technology, came the portable version of the electricity storage unit known as Portable generators. The introduction of portable generators created a bit of a sensation amongst the people as they were an appropriate solution to the power outage problem. Being portable, it was easy to carry them anyplace due to which the lack of electricity was hardly a problem.

A portable generator comes with an ample amount of uses, and in today’s world, where you cannot afford to have any interruption in your routine, these generators come handy. Though with technical advancements, there have been numerous elevated versions of a simple portable generator available in the market. While a portable generator can ease out many things for you, it becomes a tedious task to select one. With several variants available in the market, choosing the best portable generator for oneself can take a while.

In this guide, we have tried to consolidate all the information related to the portable generator that might help you in choosing the best portable generator.

Types Of Portable Generators

The portable generators can be categorized through various means like categorization based on fuel, categorization based on the mode of input, categorization based on start or classification based on size. While it is vital to own a portable generator, it is of utmost importance to understand its different types and then choose the best portable generator.

Categorization Based On Mode Of Input

Firstly, we will elaborate on the types of portable generator based upon their mode of input. As per the method of input, portable generators can be divided into three categories:

1. Conventional Portable Generators

These types of generators are the classic types. The conventional portable generator uses the mechanical energy produced by the consumption of fuel to generate the output of electrical power. A combustion engine is used in these types of generators to produce electricity. They are built in an open frame and thus, create noise during usage. A conventional generator works upon the old technology and uses the copper windings to produce electricity, which makes it bulkier to use.

Though being heavy and loud, the conventional generators offer a better ratio of price to power and can be used to serve countless purposes. Amongst the numerous uses of the conventional generator, few of them are enlisted below:

  • Can be used at remote job sites
  • As a backup power solution for emergencies
  • At holiday homes or cabins
  • Used by the companies that provide generator on rent
  • For general home usage.

Also, while using conventional portable generators, few things should be kept in mind. It is crucial to maintain a speed of 3600 Rpm while using the generator to provide the standard amount of current. To manage or control the speed of the engine, a governor can be used.

2. Inverter Alternator Generators

The inverter generator works with the help of an engine to generate AC power output. Unlike other generators which use DC as their input and convert it into AC, inverter generator uses a rectifier which allows it to transform the AC into the DC. These generators depend upon the high technology magnets to produce the flow of charge and use advanced electronic circuitry. This sophisticated circuit works in three phases to produce electricity. It generates AC as of the output which is converted into DC using a rectifier, which is finally inverted gain into AC with the help of an alternator.

The inverter generator is built and stored inside a case which helps to reduce the noise. Thus, they tend to be noise-free and come in the compact sizing as compared to the conventional portable generators. Also, these generators are energy and fuel-efficient as they maintain a constant flow of current to an appliance and the engine adjusts its speed depending upon the amount of current required. Other than that, using proper equipment, we can alter the voltage and frequency of the AC as per the need.

Being light weighted and quiet, the inverter generators find their use in many places. Few of the applications of inverter generator are as following:

  • Being portable can be used on a camping trip.
  • Can be fitted into a car or a boat.
  • It can be used in Tailgating
  • Are perfect while planning a weekend party
  • Have significant regular use at home and can be used as a power source for small appliances like TV, laptops, etc.

3. Solar Generator

The solar generator runs on the electricity which is produced using solar energy. These generators constitute of solar panels, battery charger, solar batteries, and inverter. Solar panels use solar energy and generate electricity as output. Battery charger uses the electricity generated by the solar panels to charge the generator battery. The batteries installed in this generator are solar batteries and power generated by the batteries is converted into the AC to be used by the appliances utilizing an inverter.

Though solar generators are noise-free, they come with solar panels handling which can become a task while carrying the generator. Also, the amount of energy stored in these generators is quite less as compared to the inverter or conventional portable generator. While being user-friendly, the solar generator can only be used to charge small devices or appliances like phones, lights, camp fridge, etc. If you are planning a camping trip at a remote location where you have minimal electricity requirement, a solar generator is the best choice for you. The lower levels of recurring electrical load make a solar generator the best portable generator to be used at remote locations.

Categorization Based On Fuel Source

Now, emphasizing upon the types of portable generators on the basis of the fuel used, these can be divided broadly into five categories:

1. Gasoline Fuel Generators

Gasoline fuel generators are the most common types of portable generators. It is due to the easy availability of gasoline along with the lower cost price of these generators. These generators use combustion engines to burn gasoline to produce electricity.


  • Appropriate for portable generator models as they come in a compact size
  • Easy availability of Gasoline


  • Lower cost
  • As electricity is required to pump gasoline, it is often unavailable during a power outage.
  • Gasoline as a fuel is highly flammable
  • The price of Gasoline is comparatively higher than other fuels
  • Combustion gasoline produces high emissions.
  • These generators do not have a long shelf life, and even gasoline can also be stored for less than a year.
  • The Gasoline generators might create a problem while starting in cold weather.

2. Propane Fuel Generators

Propane fuel generators are less common as compared to gasoline fuel generators. This generator runs exclusively on propane gas. The propane generator comes with varied fuel tank sizes, which cause an impact upon the run time of the generator. These generators can be used to provide power backup for tankless water heaters as well.


  • Burns with low emission
  • Environment-Friendly
  • Propane comes with a longer shelf life and can be stored for an infinite period. This reduces the chances of you running out of fuel at the time of power outage.
  • Noise-free
  • Suitable for any environment and works well, even in wet places.
  • Propane burns in a clean manner
  • Fewer chances of spilling due to cylinder packaging


  • Propane is required to be stored under pressure as it is highly flammable and can turn explosive at times.
  • These generators have a complex fuel system and thus, are more prone to failures.
  • The cost of installation of a propane generator is high.
  • Propane fuel generator is comparatively expensive and requires triple the amount of fuel as compared to other fuel generators.
  • Susceptible to low temperatures

3. Dual Fuel Generators

Dual fuel generators are one of the most versatile generators. These generators generally have two fuel tanks, where two different fuels can be stored and as per the necessity, the fuel can be chosen. There are numerous versions of dual fuel generators using a different combination of fuels. While most of the fuel combinations can be used in these generators, the most popular and efficient fuel combination is gasoline and propane. On the one hand, gasoline is readily available, and the usage of gasoline provides efficient results, and on the other hand, propane is more environment-friendly and has a long storage life.


  • Provides you the choice on fuel to be burnt as per the need.
  • Depending upon the size, dual fuel generators can even provide backup power supply to air conditioner
  • Supplied with a transfer switch to change the fuel source
  • Highly efficient


  • The technology used varies with different variants, and at times it might be required to shut down the generator to change the fuel source
  • Dual-fuel source can sometimes cause confusion
  • Needs to be taken care while using outdoors

4. Hydrogen Fuel Generators

Since the past many centuries, research has been done to use hydrogen as a power source to generate electricity. Hydrogen has been quite a preferable source because of the benefits associated with it. Hydrogen can be found in abundance in our environment, which makes it readily available and does not have any harmful reaction, thus non-toxic. Also, apart from burning cleanly, the quantity of energy produced per pound is more than other fuel sources.

Despite being cheap, the hydrogen fuel generators are extremely rare in the market. Though having a minimal presence in the market, hydrogen fuel generators are incredibly safe to be used in any environment and even in laboratories as well.

These portable generators come with an electric start and have a circuit build within themselves that can be triggered using a switch. The switch provides the electrical signal to the engine to start its working. Most of the small portable generators come with an electric start.

2. Pull Start

Most of the heavy-duty or gasoline fuel generators come with a pull start mechanism. In these generators, recoil spring is attached to the clutch and the crankshaft of the engine. So, when the rope is pulled, the spring stretches out, thus engaging the clutch and turning the crankshaft resulting in starting the engine. These generators are required to be started manually every time they are needed.

3.    Remote Start

There are a few of the portable generators which have access through the remote. They catch the signals of the remote and ignite the engine of the generator.

Voltage Regulation Types Used In Portable Generators

While using a portable generator, it is essential to consider whether or not it is providing a constant supply of current to the electronic devices. Since the generator in itself is rotating, it may become a task to provide a continuous power supply. However, it can be achieved using voltage regulation.

There are two main types of the voltage regulators available in the portable generators:

Automatic Voltage Regulation: The technology of the automatic voltage regulation (AVR) uses an assembly of sensors to monitor the speed of the engine. These sensors are also responsible for stabilizing the voltage of the generator.

Inverter Technology: Current portable generators use inverter technology to regulate the voltage, and the inverter technology is being considered as the best means for voltage regulation. The tension generated by the alternator is used by the electric components of the generator and is recreated. Thus, the recreated current by the inverter is considered to be a clean sine wave and is reckoned the perfect current flow. This technology is observed as the best solution while powering sensitive electronic devices like mobiles or laptops. It is also incorporated with the injection mechanism, where the speed of the engine is reduced during the lower loads.

Calculate The Run Time Of The Portable Generator

Portable generators are developed in a way to provide backup power supply at the time of power outage. Every generator is designed to run, uninterrupted, for a particular duration of time depending upon their design and fuel tank capacity. This time for which the generator can run uninterrupted is referred to as the run time.

The run time of the fuel-driven generators are measured in “Watts” and are often calculated at either half load, i.e., running the generator at 50% of its power capacity, or quarter load, i.e., running the generator at 25% of its power capacity, with a tank filled with fuel.

However, in the case of the solar generator, the run time is calculated in “WH” or Watts per Hour. In solar generators, with no fuel tank availability, the bigger the connecting loads, the more is the run time. Also significant is the number of sun hours required by the solar generator to charge completely. In solar generator with rechargeable batteries, the run time also depends upon the number of hours for the battery to fully charge.

Running Power and Surge Power

Every generator has two marks or levels in terms of power, referred to as running time and surge time. Both of these power levels are measured in “Watts.”

Running time, also referred to as running watts, is described by the capacity of a generator when ran over a continuous period.

While every appliance requires a continuous flow of power, they tend to consume more power while turning on. Surge power, also known as starting watts or starting power, is that extra amount of flow, held by the generators for a few seconds only, to cater to the need of the increased power by the appliances.

Transfer Switch

A transfer switch is an integral part of the generator which connects it to the home’s wiring through a utility grid. Often with a regular supply of electricity, there is a risk of the generator to turn on simultaneously. This may act as a circuit breaker and result in blown circuits or even fire. Transfer switch blocks the electricity supply to the generator, when not needed, to prevent it from starting gradually.

Another important reason to install a transfer switch in your generator is to prevent the backfeed. Backfeed is referred to as the movement of electric waves in a direction opposite to the normal flow. This can create life-threatening situations. It can occur if the generator is directly connected to the main outlet of the house or is plugged into the primary grid of the area.

Thus, to prevent any damage, it is always recommended to connect the generator to the main utility grid of the building using a transfer switch.

Types Of Outlets

Different portable generators come with a varied number of outlets. However, these outlets can, into two categories:

  • 120 Volt with 20 Amp Plug
  • 120/240 Volt with 30 Amp Plug

These outlets refer to their limit of the volts and amps to be fed. Each device and appliance requires a particular amount of amps and volts to get charged. It is to be kept in mind not to exceed this limit. Also, it is recommended to get a circuit breaker fitted into your generator to protect both the generator and the devices connected, in case of overload.

Also, regarding the number of outlets, it is advised to have multiple outlets in the portable generator. This is because different outlets help in spreading the load. So, when numerous devices are connected to a generator, several outlets help in stabilizing the power of the generator. Also, more the number of outlets with different limits, more devices with varied power requirements can be connected.

Add-On Features For The Portable Generator

Though it is difficult to get a perfect generator for yourself with all the features, it is crucial to have the best portable generator suiting your needs. In your quest to find the best portable generator for yourself, you can add some extra features to the generator to make it more user-friendly.

Following Features Can Be Added To The Portable Generator To Enhance Its Working:

Fuel Gauge: Fuel gauge helps you keep track of the amount of fuel left in the generator. It is essential to keep track of the leftover fuel tank not to let your generator run out of the fuel and leave you helpless in noise-free. As the design of each portable generator varies, it might become a cumbersome task to know the exact amount of the fuel left in the portable generator. This can be eased by installing a fuel gauge into your generator to allow you to keep visual track of the depleting levels of fuel.

Fuel Stabilizer: Though running out of fuel becomes a problematic situation; the same is the case with the leftover fuel in your generator. Every fuel has a particular lifespan to which it can be stored and after which it is ruined. The ruined fuel can have adverse effects on the portable generator. Also, it becomes an even clumsier task to try and empty the fuel tank. Thus, fuel stabilizers are added into the fuel which safeguards your generator from possible corrosion and also prevents the potential starting issues.

Mufflers: Unlike the solar generators and inverter generators, most of the fuel-driven generators make enormous noise while running. Even more the power of the portable generator, louder the noise becomes. This noise can create a nuisance, and even your neighbors can object to this unpleasing noise at the time of power outage. To reduce the sound of the generators, mufflers can fuel-efficient in various designs. Though mufflers don’t make the generator completely silent, they do reduce the noise to a great extent.

Push Start Battery: As studied in different types of starts, many portable generators come with a pull start mechanism. Pulling the rope requires excellent strength and can become a laborious task, especially when it is expected to be drawn numerous times. It can become a roadblock, particularly for older people. Though various portable generators, nowadays, come with electric start. However, if that is not the case, a battery can be installed in the generator with all the necessary wiring being directed to a button, which will act as a push start button.

Wireless Remote Start: Apart from the electric or pull-start, the present-day portable generators come with access to a wireless remote. This is a new feature and can be installed in your portable generator depending upon the design compatibility of the generator. Establishing this feature allows you to control your generator, from a distance, using a wireless key. The range can be extended anywhere up to 80 feet. These wireless remotes are beneficial for portable generators at the worksite.
