You’ve decided which type that best fits your needs. But now you’re trying to determine which one is the best one you can afford. If you’re reading this, you’re probably the type of person who likes to have all the information before making a purchase decision.

Believe it or not, deciding on where you will mostly use your portable generator is important.

Because each place has different power demands that can influence which inverter generator size you’ll want to purchase.

Home Backup: Simultaneously running various machines and entertainment devices requires extra power.


Champion RV Ready Portable Inverter Generator at a Glance:
  • Large portable generatorsusually tap out at 7000 watts.
  • This range is suitable for powering all your essential appliances, including the TV, refrigerator, freezer, sump pump, and can also be connected to your house with a transfer switch.
  • If power outages are more frequent, then please refer to standby generators.
  • Job Site: Power tools in construction sites require a lot of power to function correctly.

Primarily, during start-up, these include drills, sanders, and circular saws. Portable generators in the range of 2500 to 4500 watts should be sufficient for job sites.

RV, Boat: For extended off-grid living, you want a well-suited size for your plug-in appliances such as the fridge, microwave oven, space heater, and coffee maker.

In this case, the 3000-watt range should be ideal. It is also suitable for running an air conditioning unit.

Camping, Tailgating: If you want to power a fan, a blender, and charge your phone or laptop, then the 2000-watt range will suffice. Since there is not much that needs electricity in the middle of the woods, small inverter generators should be ideal.

You may also be interested in portable solar generators. Please check our guide to learn more about how to calculate your power requirements.

Most inverter generators tend to use gas as the primary fuel type. However, there are also dual-fuel generators that are capable of using either gas or LPG.

Inverter portable generators usually have gas tanks that hold between 1.0 to 3.0 gallons of fuel, which may not seem like a lot in run time at first glance.

Key Features of Inverter Generator

Yamaha Gas Powered Portable Inverter at a Glance:
  • However, most models have an economy mode switch.
  • It is often referred to as Idle-control, Eco-mode, Smart-throttle, or Eco-throttle.
  • This mode uses a load-sensing mechanism that automatically adjusts the engine speed to produce only the required load for your electrical devices.
  • When you connect a few devices, the motor speed increases in response to the electrical draw.

When you disconnect them, the motor speed slows down again. A machine with Eco-throttle control can run at varying speeds to match the output and burn only as much fuel as needed while maintaining the proper voltage and frequency.

Since the engine does not have to run continuously at full speed, it can significantly reduce fuel consumption by 20 to 40%. So you can enjoy an extended power supply.

This further helps reduce the overall exhaust emissions and the noise levels, since a portable generator is loudest when running at full electrical load.

Inverter generators are the very definition of portable generators. They make portability a primary manufacturing goal. There are open frame models for high wattage solutions. However, in most cases, they have a compact enclosed case design.

Portable generators are typically sized around two or three cubic feet. So it’s not unusual to find portable units under 75 pounds.

They are most often light enough to be hand-carried with just a handle.

Inverter Generators Frequently Asked Questions (FAQ)

Westinghouse iGen2200 Portable Inverter Generator at a Glance:
  • Large units usually utilize wheels and handles to maintain portability.
  • One of the best features of some inverter generators is the parallel capability option.
  • This feature allows you to link two generators together to increase your power capacity.
  • Usually, this feature is limited to connecting two identical units to share the load and deliver double the power output.

It allows you to have the portability of inverter generators while achieving higher power output with a capacity to run an entire home during a power outage.

An inverter portable generator can quietly power the devices you need to run. However, it’s necessary to consider the noise rating, since there is a big difference between one machine and the other.

Noise is measured in decibels (dB) for portable power machines. The higher the decibel rating, the louder it is. Most manufacturers measure the noise levels from a distance of 23 feet.

At quarter load, the noise level of some models can drop to 48 decibels. However, at higher loads, the scale is bound to change. So, anything above 60 decibels is higher than average.

As a result, it’s necessary to compare various models from highly-rated brands.

If you’re not familiar with the ins and outs of portable inverter generators, then you will want a unit that has some user-friendly features, such as:. Low-oil indicator: An oil alert system that warns you when your portable generator is running low on oil.

Fuel meter: A fuel gauge is necessary for monitoring the fuel level. Hour meter: An LED display or a digital display is useful for showing the running time, watts in use, and much more.

Wireless remote start: This option allows you to start and stop your unit with a remote start from a distance of up to 300 feet.

CO guard: A carbon monoxide guard allows the generator to automatically shut down if high levels of CO accumulate around the generator.

Vital Guide for the Best Inverter Generators

WEN CARB Compliant Inverter Generator at a Glance:

A good inverter generator will come standard with these features. However, make sure to check and weigh out your options. Avoiding the following mistakes will ensure that you purchase the best one to buy for your power needs.

Be aware of industry jargon and only focus on the specifications of each portable generator.

All manufacturers advertise their models as the best ones on the market. Don’t get caught up in selling tactics. Instead, compare models from different brands to find the best one that fits your budget and needs.

Get an inverter portable generator manufactured by a well-known brand. If you look all over and no one has heard of the company. Then it is best not to purchase from them.

Make sure that you get a good warranty. If two models match your needs equally, then check the warranty.
