How to Choose the Best Portable Inverter Generator

Similar to buying regular generators, the first thing that you need to think of when choosing an inverter generator is its power output versus your wattage needs.

So, I suggest that you first identify all the appliances that you’ll want to power with your portable inverter generator and then add their total wattage demand.

Of course, this will greatly depend on where and when you plan to power up the generator, for instance, at home during an emergency power outage, during a tailgating party, or even in a camp.

When determining your total wattage requirements, there are 2 values that you need to keep in mind – starting watts and running watts.

  • Running watts (a.k.a rated watts or continuous watts) refer to the amount of power that a given appliance requires to run continuously
  • Starting watts is the power that a given appliance requires to start and it’s usually notably higher than the rated watts. For instance, a freezer with a rated wattage of 700 watts may require up to 2200 watts to start

After identifying the total wattage that your ideal inverter generator should output, compare the available options in terms of runtime. This refers to how long a model can run on a full tank at 50% or 25% load. The essence of this is to get the best machine in terms of fuel efficiency.

Why Choose an Inverter Generator Over a Regular Generator?

Your choice between conventional and inverter generators is generally a matter of preference. It will highly depend on a few factors including your wattage needs and where and when you plan to use the generator.

Here are the key strengths of an inverter generator:

Portability at its best

Inverter generators have excellent portability because of their lightweight. It’s undeniable that manufacturers have been able to engineer relatively lightweight regular generators of late- a good example being the Durostar DS4000S that weighs 90 pounds and which I believe is one of the best portable generators out there. But that’s still a far cry from the weight of the best inverter generators that weigh well below 50 pounds while still being able to output enough power for some basic loads. Inverter generators are also much more compact which allows you to transport them easily in your car’s trunk or boat.

Extremely quiet

Portable inverter generators are also substantially quieter in comparison to regular generators. Most inverter generators operate at between 49 and 69 dBA- the same range within which a normal conversation takes place. Regular generators, on the other hand, are found at 70-80 dBA. Just so you know how loud these models can get, power saws and jackhammers fall in the same noise level.

This means that an inverter generator will be a perfect fit if you are to use it in areas with noise regulations particularly at night including your neighborhood, camping grounds and when caravanning. A quiet generator is a prerequisite during a tailgating party too.

High fuel efficiency

The ability to reduce fuel consumption by up to 40% is yet another big reason why you’d want an inverter generator. And it’s not hard to understand why they are able to do so.

You see, a regular portable generator is programmed to constantly make 3,600 RPMs regardless of the load (load refers to the number of appliances that have been plugged in). On the other hand, inverter generators are engineered to adjust the speed of the engine to match the power requirements.

Parallel capability

The major drawback of inverter generators is their relatively lower power output. Most of them max out at 4,000 watts which might not be enough to power up several power-hungry tools and equipment. In such instances, you could simply pair two identically sized units rather than getting a larger traditional generator. This allows you to get more power without sacrificing portability and quiet operations.

Inverter Generators don’t WIN all the time, though…

Don’t fall their strengths just yet. Portable inverter generators have their set of drawbacks that might also influence your decision.

  • Lower power output– the most powerful inverter generators output around 4,000 watts. So, if you want a generator that can power up an entire job site or a mansion, you’ll need either two inverters or a regular generator
  • Price– within the same power rating, inverter generators are much more expensive than conventional generators
  • Fuel tank size– inverter generators are built around optimum portability and compact design- something that they achieve by incorporating smaller components including a smaller fuel tank. This means that everything else held constant, an inverter generator will require regular fills than an identically rated traditional generator.

Where Can You Use a Portable Inverter Generator?

Inverter generators can be used pretty much anywhere where there’s the need for a portable power solution. They are also ideal where a generator with an extremely low noise level is necessary, for instance, in a campsite and when tailgating.

But keep in mind that low power output is the major limiting factor of these machines. That being said, you’ll need to have reasonable wattage demands especially if you want to use it at home and at a job site.

Inverter generators are mostly used in camping and tailgating parties as they can power up pretty much all your appliances in these applications:

  • Electric grill- 1650 watts
  • Box Fan 20’’- 200 watts
  • CD/DVD player- 100 watts
  • AM/FM radio- 100 watts

Important Considerations When Buying an Inverter Generator

Power output

power bolt iconAs I told you earlier on, the very first thing that you need to consider when purchasing an inverter generator is the amount of power that it can supply. The big question here is whether the generator will be able to power up the appliances that you intend to use together whether at home, at a job site, or during outdoor recreational activities (camping, tailgating, boating, caravanning, etc).

To arrive at your total wattage requirements, add the total running watts of your appliances and then add the highest starting watt. With this figure in mind, identify the inverter generators whose rated wattage meets your power requirements.

If you already know how much watts you’re going to need, you might want to check our reviews on:

Runtime and fuel efficiency

After identifying several models that output enough power for your need, compare them in terms of runtime. Runtime refers to how long in hours a generator will run on a full tank at a specified power load; 100%, 50% or 25%. The longer a generator can run before the need for refueling, the better for you.

Runtime is not everything, though. You also need to rank your target inverter generators in terms of fuel efficiency. To narrow down to the best contenders, divide the runtime on full load by the capacity of the fuel tank and this will give you a clear picture of how long each generator will power your appliances per gallon.

Portability and maneuverability

Although inverter technology generally makes these generators relatively lightweight and compact, they are not equal. You’ll still find some that are much lighter than others. So, consider the weight of each model and some additional features that have been put in place to boost maneuverability such as handles and wheels.

Reliability

Let’s face it: a generator with a promise of high fuel efficiency, a longer runtime, and higher output will be totally useless if it can’t meet your power demands without failing and tripping the circuit every now and then.

While there are some good inverter generators out there, there are others that will start off nicely only to fail an hour or two later. On this note, I highly recommend that you consider reputable brands and also check out previous users’ feedback on your target generator’s reliability.

Frequently Asked Questions

Do inverter generators require gas to run?

Yes. Similar to a regular generator, inverters also run on gasoline. These models are, however, very efficient because they are built with idle control commonly known as ‘eco-throttle’. This feature adjusts the speed of the engine as necessary and only burns just enough fuel to power up the appliances at hand.

How is an inverter generator different from a regular generator?

An inverter generator works in a similar manner to a conventional generator to some degree. Both of them start by producing raw, high-voltage AC current. And then everything changes from here. After producing raw multiphase AC power, the inverter generator converts it into DC power using an inverter and then back into AC but in a clean, stable, and consistent manner almost similar to what you get from the grid.

What is the 12V DC receptacle on an inverter generator for?

This power outlet comes in handy when you want to charge an automotive battery during emergencies and short –term charges. Keep in mind that it is usually not regulated and will vary in response to the generator’s RPMs. Again, it won’t cut the charge when the battery is full. That’s to say that it’s not a reliable source to charge the battery to capacity.

Can I power my laptop using a portable inverter generator?

Yes, inverter generators are the most recommended especially if you’ll be powering several power-sensitive appliances. This is because they are fitted with a Microprocessor-controlled Sine Wave Inverter which outputs energy in clean power with smooth sine-wave characteristics.

So, yes, you can power your laptop and iPhones from a portable inverter generator with zero risks of damage.

Do inverter generators require maintenance?

Of course, the key to a long-lasting generator is good and timely maintenance. Maintaining an inverter generator isn’t as expensive as a regular generator, though. Inverter generator maintenance mainly involves:

  • Changing the oil usually after the first 20 hours and then after every 3-6 months depending on usage
  • Cleaning the air filter after every 50 hours of runtime or after 3 months (whichever comes first)
  • Adjusting the spark plug after every 100 hours of use and replacing it completely after 1 year or after 200 hours of use
  • Cleaning the spark arrestor

Are inverter generators the best?

Well, it will depend on the features that make the best generator in your opinion. Inverter generators reign in terms of compact design, portability, fuel efficiency, and lower costs of operations. They are also the quietest. On the other hand, manufacturers are yet to make models with lots of power. Most of them max out at 4,000 watts.

Conclusion

I hope our inverter generator reviews have helped you to select the right mode for your power needs. However, if you need some extra help in choosing the best portable inverter generator, I’d highly recommend the Champion 3400-watt generator. It has enough power to run most of your household appliances during emergencies. It can run on either propane or gasoline. And it has a 30-amp port that makes it perfect for RVs. It’s not a cheap inverter generator but you can rest assured it won’t fail you as long as you take good care of it.
