Small Portable Generator Buying Guide

So, these were the six smallest portable generators available in the market. You can select any one of these Gensets that best suits your specific requirements.

However, we would recommend you to consider some of the critical factors in addition to its portability before buying a small portable Genset.


Your selection would depend on the frequency of using the generator. If you require using the generator almost every day, you must select a good brand offering a high-performance level and fuel efficiency.

You may even pay a higher initial cost. It will get compensated over time by the lower operating price of the generator.

If the requirement is only occasional, go for any renowned model that gives you a fairly reliable performance.

Output Rating

This is one of the most important factors to be considered while buying a generator. The output of a generator is defined as the output power that it generates in watts. The generator manufacturers provide two different ratings. One is the peak or surge output, and the other is the running output.

While the running output signifies the actual power rating during the regular running of the unit, the peak rating takes care of the surge conditions.

To evaluate the power rating required for your purpose, you have to add up the power ratings of all the equipment you want to run through the generator.


Ensure that the generator complies with all the standard safety norms and has approval from the recognized certifying audit agencies.

Fuel Tank Capacity

A bigger fuel tank would mean a longer duration of the non-interrupted operation. So, it is simple. You have to select the generator with a tank capacity as per your running requirements to avoid frequent refilling.

However, the bigger tank’s flip side is that the generator would be more massive with a full tank.

Noise Level

Usually, small generators produce less noise. Therefore, it is comparatively easier to find a quiet generator in the small Genset category.

Other Features

After considering the significant factors, you can choose among the various convenience features like Remote control, Injection type, Auto restart, Auto shut-off, and Level indicator, etc. as per your need.

What are the benefits of a Small Portable Generator?

Portable generators have some distinct benefits over other types of generators. Some of these benefits are presented here:

Easy to Move

The small size and lightweight makes it easy to carry and install at different locations. You can take them outdoors as well for any adventure trip like camping or hunting.

Simple to Use

These generators are highly user-friendly. You do not need to be tech-savvy to operate these machines.

Highly useful in Emergency

There are times when you cannot afford a power cut. It may be a critical task to finish, or there may be a medical condition or any such emergency.

Portable generators are pretty handy in providing power in quick time without any difficulty.

Cost Saving Opportunity

If you require power supply at different locations at different times, you can use the same generator in all areas. This way, you save on your investment cost.

Fuel economy

The fuel economy of a generator depends on multiple factors, including Genset’s size, its operating load, and the operating mode.

Bigger Gensets have better fuel efficiency. The portable generator has a small size and has a lower fuel economy.

However, some manufacturers use advanced technology to offer you higher efficiency even in the small portable category.

For instance, Honda Gensets use the Eco-throttle feature. This feature allows the engine to adjust fuel supply as per the load requirement, thus restricting fuel consumption during lower load conditions.

Moreover, the mechanically powered Gensets have lower efficiency as compared to their electronic powered counterparts.

Noise level

The noise level in a portable generator ranges from 47 dB to 78 dB depending on the Genset’s capacity.

A 1,000-watt generator would be on the lower noise level range, while a 10,000-watt appliance would be on the higher end of the noise level.

However, there are ways to reduce the effect of the noise level. For instance, Yamaha EF1000iS uses acoustic enclosures to reduce the impact of noise.

At your end also you can control its impact by keeping the generator in an enclosed area or an area away from your place of operation.

Energy Source

Different generators use different types of energy sources. It may be gasoline, diesel, or propane.

While diesel offers more efficiency, gasoline has the advantage of easy availability. The propane, on the other hand, provides cleaner burning.

On the flip side, gasoline has a short shelf life and is highly flammable, while diesel availability may be a concern in some areas. Propane has the disadvantage of having a higher initial cost and has a more complex fuel system than others.

Some manufacturers like Jackery Portable Power Station Explorer 160 use a battery as the energy source. Battery operated Gensets have restricted power capacity. However, they offer a fumeless operation.


This is one of the significant features that you would want to have in a portable generator. A small portable generator is easy to move from one location to another and can also be installed in a small space.

The size of the generator is also affected by its capacity. The higher the capacity, the bigger is the size of the Genset.

So, before determining the generator’s power rating, you must include only the essential appliance to connect through it. This will allow you to choose a smaller generator that would offer you higher portability.

Final Thoughts

In the article, you have gone through the top 6 smallest portable generators available in the market. You also came to know the factors to be considered while buying the smaller Genset.

We hope that with this information, you would make an informed decision while purchasing the best small size portable generator for your needs.
