What is an inverter portable generator?

An inverter generator consumes gas or propane to normally run their combustion engine. Being portable means that the generator can be carried to any place without any problem or hassle. These generators are usually lightweight.

Furthermore, they are designed to produce electricity in AC, which is then transformed into DC power. Afterwards, this power is supplied to your appliances and they run. Usually the engine speed of the inverter portable generators varies with the demand.

The advantages of an inverter generator

An inverter generator provides you with a number of advantages over the conventional generators. The most favorable and user friendly feature of inverter generators is that they are much quieter. They do not produce loud noise.

Additionally, the inverter generators are lightweight and therefore, are easy to carry around places. This feature makes the inverter generators extremely portable. That is why they are widely used by tour planners and people who often go on camping.

Fuel efficiency is another great feature of the inverter generators. They are much more energy efficient than the other conventional generators. Most of the inverter generators run for 7 – 8 hours at ½ loads.

 In addition, the electricity produced by the inverter generators is in the safe range. You can easily use these generators to charge your mobile phone, laptops and other electronic gadgets.

The difference between inverter generators and portable generators

If you are confused about the choice of the generator. And you are thinking of shifting from a conventional to an inverter generator. Or you are buying a new generator for the first time. We are here to help you.

Below is the list of some of the important differences between a conventional generator and an inverter generator.


The production of type of electricity is the main technical difference between an inverter and conventional generator. A conventional generator produces electricity in AC current. On the other hand, an inverter generator produces Ac current and then a built-in converter converts the AC in to DC which is then again changed to AC. Finally, you will get a stable voltage.

The production of stable voltage prevents any possible damage to your appliances. Therefore, this is said to be a “clean source of electricity”. You do not have to worry about the electronic devices or gadgets getting destroyed because of high voltage.

Fuel efficiency and power:

Another major difference between the convention and an inverter generator is the fuel efficiency. Conventional generators are known to produce more power. Therefore, they consume more fuel. Furthermore, they do not have the capability to adjust to the load.

Contrary to this, the inverter generators have the ability to make adjustments according to the load. Therefore, they consume less fuel and work efficiently. Furthermore, the production of stable AC current is also the reason behind the fuel efficiency in these inverters.


The amount of power produced and the engine power has a major role in the portability of the generators. Inverter generators are lightweight and have a system of producing stable electricity therefore, they are more portable than the others.

On the other hand, the conventional generators produce more power and have a huge fuel tank. Therefore, they are heavier and have wheels installed for their portability. This helps in the movement of these heavy generators.

Noise levels:

The loud noise produced by conventional generators is their major flaw. People get tired of listening to the noise all the time. Especially if you are at a camp side, this noise will ruin your mood. Therefore, the inverter generators are made to produce less noise.

Usually the speed of the inverter generators is 3600 rpm and therefore, the noise production id reduced. The average noise levels produced by inverter generators range from 50 – 60 decibels. Furthermore, you can also get the necessary information about the noise levels from the detailed chart.

Parallel connections:

Parallel connection is needed for the management of the proper stable power output. Conventional generators already produce high amount of power and their portability is also low. Therefore, they do not have the parallel connection option.

On the other hand, the inverter generators produce less amount of power. Therefore, to balance the power demands for the high power intensive things, parallel connections are used. For making a parallel connection, two generators are combining together through a cable and double amount of power is obtained.


Emission of both generators is different. Conventional generators tend to release more toxic gases and therefore, are a threat to the natural environment. Contrary to this, the inverter generators are designed to lessen the emissions to higher extent.

Furthermore, the release of greenhouse gases by the inverters is much lower than that of the conventional ones.

Price range:

The price range of both of the generators is different. Conventional generators tend to be cheaper and are more affordable considering the power it provides. On the other hand, the inverter generators are much expensive because of the use of best quality parts. Furthermore, they are made quieter and fuel efficient, thus, this adds in the price tag.

How to choose the best portable inverter generator?

Power Capacity:

The power capacity of the inverter generator is highly important. It determines the capacity of the generator to power the electronic devices. For instance, if you want to run a water pump, the generator must have a 1000 Watt of running power capacity. For a deep freezer, the 500 Watt of power capacity is enough.


The mobility is highly important because the name shoes it is portable. So, most of the inverter generators are designed to be carried around anywhere. Moreover, they are lightweight, which further ads up to their portability.

Is it ready for RV:

The inverter generators are usually compatible to be used to power up the RV. Therefore, you must check it before buying one. The details of compatibility of the generator are available on the buying page. So, you must look for it, if you want the generator for your RV.


Starting the invertible generators is different. Some of the generators have a complex startup and you will need assistance for that. But most of the inverter generators do not have such a complex system. They usually have a push button that starts the generator.


If you need the generator of recreational places and you are often on the road, then you must look for stability of the generator. Usually wheels that are flat-free are used in such generators that not only add stability but also their mobility.

Fuel Source & Fuel Consumption:

Fuel source and fuel consumption of the inverter generators varies with their manufacturing and other specifications. Usually these generators are made fuel efficient and does not consume much as compared to the conventional ones. The fuel source for most of the generators is gas, but some also have dual system for fuel.


Safeguarding is the most important of any electrical tool and machine. Without an exception a completely safe generator would be better to be used. Safeguarding of not only the surrounding people but also of the generator itself is important. Therefore, for the protection of the generator, the structure is designed in such a way.

Noise Level:

Inverter generators do not produce much noise. Furthermore, the noise level generated by these generators is specified on their sites. Therefore, if you do want to get a rid of the generator noise, have a look at that first.

Product Dimensions & Weight:

Product dimensions and weight of the generator directly effects their mobility and portability. Therefore, if you want a more mobile generator, you must look for its weight and dimensions. Lightweight and low dimension generators are better to be carried around to trips etc.

Warranty & Service:

A better warranty shows that the manufacturer is sure of the quality of his product. Moreover, you will have the opportunity to get the benefit of repairing the generator in case of any issue. Therefore, you must look for a generator that provides you with the long term warranty.
