Portable Inverter Generator

Spread the love

When there is a power outage because of a storm or equipment failure, some homes and businesses rely on their generators for electricity. However, generators use too much fossil fuel and emit exhaust, which is toxic for the environment and human health.

Fortunately, there is a better and cleaner alternative source of power that they can use, which is an inverter generator. This latest development was introduced more than a decade ago, utilizing the power of a generator and an inverter in one smaller and lighter machine that you can take anywhere. For this reason, some manufacturers describe them as portable inverter generators.

Choosing the right portable inverter generator is not an easy feat. Although it is common knowledge that this machine is safer than generators, it still best to consider certain features to ensure overall safety. For you to learn what these important features are, you should first know how inverter generators are different from a generator and an inverter, how it works, and why it is a better choice.

In this article, you will also learn the answer to the questions: Do you really need this particular type of inverter generator? How do you know which one will be the best for your home, RV, campsite, or boat?

Generator vs. inverter vs. inverter generator

In layman’s terminology, these three power supply terms are often used interchangeably. They either say inverter or generator, when they are actually referring to an inverter generator.

Well, you cannot really blame them because even manufacturers of inverter generators often clip the whole terminology. So aside from the names, how are they different from each other? You will notice that the main difference between the three are the processes or method they use to supply power.


A conventional generator does not have the capacity to create electricity, but it does cause the flow of electricity. To produce AC power, it needs fossil fuel or an energy source like gasoline or propane. Sometimes they also use diesel as their energy source.

Following a mechanical principle called electromagnetic induction, the generator uses a motor to produce AC power. The motor must run at the speed of 3,600 rpm so that the power can be available for consumption of your electronic devices that require 120 volts.

In the creation of a conventional generator, size does not matter because they are commonly used to power up the whole household or the entire business. That is why they are huge machines that need a large amount of fossil fuel. Therefore, the tendency is that they emit harmful exhaust that harms the environment. They also tend to be loud while operating.


Unlike a generator, inverters convert the DC power coming from a fixed source to AC power. The usual source would be a car battery or a solar panel.

Aside from this, an inverter is also capable of producing AC power at any voltage and frequency provided that you have the right equipment.

Inverter generator

An inverter generator, on the other hand, needs both a generator and an inverter to produce a clean and safe AC power. It needs to consume fuel to run a motor and produce AC power. However, that AC power cannot be directly used for your household items.

Therefore, it should be converted first to DC power and inverted back to AC power using an inverter module. Only then will you be able to utilize the electricity (with a single phase and sine wave) for your electronic gadgets even if it is a medical apparatus. These are all made possible because of the advanced electronic circuitry including high-tech magnets present in an inverter generator.

The developers are able to take size, weight, and noise into account when they created this lightweight inverter generator. That is why this new breed is smaller, lighter, and less noisy. They chose quieter engines and sound-dampening technology so that the noise is at the lowest level.

On the other hand, you cannot expect a smaller-than-usual market standard inverter generator to supply power for the whole household. Their average running time is only 8 hours, or 4 hours in full-capacity mode. Most models have a range of 1,000 to 4.000 watts.

When do you need a portable inverter generator?

If an inverter generator cannot supply power for all of your electrical appliances, then why should you buy one? Emergencies can come at the most unexpected time and place. And often during these times, you need to think and act fast.

During this case, having a backup supply of electricity that is easy to carry anywhere is better. The inverter generator might not be able to power your entire kitchen, but it can produce electricity for your electric stove or kettle right there and then. What’s more is that you do not need to worry about power surges because they are safe for your sensitive electronics.

Aside from this, you can also benefit from this when you are at the campsite or on a boat. Simply plug in your laptop, phones, and other devices so that you can keep yourself connected wherever you are.
