Best Inverter Generator

Last updated

Camping and overlanding don’t mean that we have to completely rough it, as they say. Even if the idea is to get away and unplug, it may be necessary to use computers and phones. If the overland adventure involves driving in an RV, extra power will be needed to take advantage of refrigeration and air-conditioning. 

This is when an inverter generator comes in handy and our list of best portable inverter generators will help you choose the right one for you.

What Is The Difference Between A Generator And An Inverter Generator

Generators have been around for a while now, allowing travelers to keep some modern appliances going out on the road. The idea is fairly simple. 

An alternator is powered by a gas or propane engine, producing the electricity needed to run electrical appliances. Traditional generators are capable of producing electricity with one hitch; they cannot produce clean energy.

Many modern appliances, especially sensitive electronics like computers, can be damaged by power dips and spikes that often occur with generated electricity. 

This is where an inverter generator comes into play, and since you might want to take it with you to the outback, you should look for a portable one.  

An inverter will produce alternating current (AC) power, convert it to direct current (DC), and then turn it into electricity that is “clean.” 

Clean energy is stable and will not damage precious devices. This is what makes the inverter generator one of the most important overlanding accessories.

What follows is a closer look at the best 8 inverter generators, each with its own advantages and limitations.

Buying Guide – Best Inverter Generator

How Does An Inverter Generator Work?

An inverter generator works a bit differently compared to a conventional generator. We can divide the entire process into 3 main steps.

First, the alternator on the inverter generator produces AC (Alternating Current) power. On the second step, the rectifier device in the inverter generator converts that AC power to DC (Direct Current) power.

In the third step, the DC power is again inverted back to clean AC power at the correct voltage.

As the device inverts/converts the DC power to AC power again, it is known as the inverter generator. Due to this mechanism, this type of generator can produce clean and stable power.

Considerations on How to Select an Inverter Generator for Your Goals

Power Capacity or Where Do You Want To Use?

First and foremost, you should figure out the total wattage you will need from your inverter generator. For that, you will have to know where you are going to use the inverter generator.

Depending on that, we can discuss 3 of the most common scenarios of using an inverter generator here. So, let’s go…

Overlanding, Camping, and RV

Many overlanders use inverter generators to power up their electronic devices while on the journey. If you are in need of an inverter generator for camping, then you can go with one that has a minimum of 2000 watts of power capacity.

On the other hand, if you want to use the inverter generator in your RV, then you should go with a bigger one. For instance, a 3100 watts inverter generator would be a sweet spot for powering up an RV refrigerator, air conditions, and other smaller accessories.

On Job Sites

A lot of people use inverter generators in their job sites. A powerful inverter generator would be capable of powering up power tools that don’t need very high power.

For example, you can run drills, rotary hammers, chainsaws, portable jigsaws, and so forth with an inverter generator. Remember, power-hungry power tools like MIG welders, air compressors, and table saws, etc. will not be compatible with portable inverter generators.

As Power Backup at Home

Admit it or not, it is not possible for a portable generator to power up all of the electrical appliances at a typical home at once.

However, if you want to power up a specific number of appliances like the TV, AC, or refrigerators only, then it is possible to do that with a 3000 to 4000 watts inverter generator. 

As always, everything will depend on the amount of power you are going to need in reality. So you have to ensure that you have figured out the amount of total power you will need from your next inverter generator.

Best Inverter Generators

Parallel Capability

The ‘Parallel Capability’ feature is one of the best features of an inverter generator. Remember, this is a rare feature, so only the best inverter generators will have it.

If your inverter generator comes with this functionality, then you will be able to connect another similar inverter generator to it to double the total energy output. Cool feature, isn’t it?

For your convenience, we have tried to include several inverter generators with the ‘Parallel Capability’ function above.

Size and Portability

While camping or overlanding, you will need a portable inverter generator. That is why we have reviewed only the best inverter generators that come with a compact size.

But some of them are bigger and heavier than the other. So make sure you know which one you are choosing — is it lightweight enough for you or is the size perfect for you?

Noise Level

Generators are known for their loud noise. Interestingly, most portable inverter generators are very quiet compared to conventional generators.

Every good generator manufacturer will specify the noise level of their inverter generators. So you have to make sure you are getting a silent one.

Typically, most inverter generators come with a 50 to 60 decibels noise level.

This is actually very quiet from generators. Still, many campsites might have specific rules and regulations about the noise level of generators.

In this case, the quieter the inverter generator the better. On the flip side, with the increase of the power, the noise level also increases in the case of inverter generators.

Clean Energy

You might think that we are talking about environment-friendly inverter generators when we are saying ‘Clean Energy’.

To be clear, every type of generator releases toxic fumes to the environment. But the inverter generators are actually far more environmentally-friendly compared to the traditional ones.

In reality, we are actually talking about the quality and stability of the power output from the inverter generator.

Normal traditional generators produce modified sine wave power. This is not suitable for operating sensitive appliances like speakers, laptops, smartphones, etc.

On the other hand, pure sine wave energy is the most suitable for operating any kind of electrical appliances. As a result, this is known as ‘Clean Energy’. 

All of these inverter generators on our list produce clean pure sine wave energy. That makes these portable generators perfect to use with any kind of modern electronic devices.

Maintenance and Warranty

It goes without saying that you should choose an inverter generator that has the best warranty policy. Also, you should take care of your inverter generator, if you want long-lasting service from it. 

Most top brands offer their products with a reliable and longer warranty policy. However, their products also tend to be a bit more expensive than the normal ones.

Still, we would recommend going with the top brands even though those are pricier.

What to Avoid When Buying an Inverter Generator

If you are new to buying an inverter generator, chances are you lack knowledge on this topic. So in this section, we will let you know some of the vital things you should avoid while buying an inverter generator. Here we go…

Buying from an Unknown Brand

Most inverter generators would be a bit expensive. So you might be tempted to buy your next one from a no-name brand that is offering the inverter generator for a cheap price.

Yes, it is saving you a few bucks in the first place. But you know it can go out of service anytime soon.

In addition, most cheap no-name brand inverter generators might not produce the specified power. Thus, it would be a problem while powering up multiple power-hungry devices at the same time. 

All in all, it is not worth it to buy an inverter generator from a no-name brand for the sake of saving a few bucks. We would always suggest going with reputed brands while choosing the best inverter generator.

Getting an Overpowered Inverter Generator

Generally, it might seem perfect to use an overpowered inverter generator. But, if you dive a little deeper, you will notice some drawbacks while using inverter generators that are more powerful than your requirements.

First of all, a more powerful inverter generator will be pricier compared to a low powered one. 

Moreover, it will be bulkier and noisier than a smaller one as well. If you use your inverter generator for overlanding trips or camping, then you should opt for a portable one.

For that reason, it is always better to use an inverter generator with the appropriate power relevant to your requirements.

Getting an Underpowered Inverter Generator

Most low-powered inverters will be cheaper as well. So buyers might be tempted to use one of those to save some money. But it is a big mistake you are making. First, you should know how much watts you are going to need exactly.

Also, you should keep the start-up/peak power required for each of your devices in mind as well. Because some devices like power tools require double the power to start-up compared to its normal power requirements.

A Less powered inverter generator could save you some money. But, what is the use of the device if you can’t power up all the required devices at the same time with your inverter generator?

So try to get an inverter generator with enough power for powering all of your devices.

Not Checking the User Feedback of the Previous Buyers

As a rule of thumb, you should always check what the previous buyers are talking about your chosen inverter generator. If the product is performing badly for most of them, you should avoid it.

On the contrary, if everybody is saying it is doing great. You can use their feedback as your inspiration to buy your next inverter generator.

Not Checking the Overall Size and Weight

You might have found the best inverter generator while researching online. It might come with the best features and functionalities.

Also, it could be from a top brand. But don’t pull the trigger yet. First, you should get to know the net dimension and the overall weight of the inverter generator. 

Many people tend to forget this significant factor before deciding on their new inverter generator.

Later, they buy it and see that it is not quite portable as they thought it would have been. So, make sure you are getting the right size inverter generator based on your requirement.
