Buyer’s Guide

Going without power is challenging. Unless you are really roughing it in the wild, it is handy to have a generator to give you some comfort and basic essentials. You want something reliable and dependable. Modern 3000 watt generators are light and portable, operate relatively quietly and offer enough power for most needs when in an RV or camping. They will also work as an emergency backup at home if there is a power outage. 

If you have used generators in the past you should have a fair idea of what to look for. There might be a few important points you have not considered. It is an important investment so you want to ensure you get the ideal option for your needs. 

There are a few important factors to consider when making your decision:


The first thing you want to be sure of is that you buy a generator that is capable to fulfill your needs and requirements. There are a number of styles, powers, and sizes available so be clear on what you want it for, how much power you need and where you intend to use it. This will help guide your selection. 


As this review looked at 3000-watt inverter generators they are all fairly similar. That is not to say, however, that they are the same. Some have a higher running power and many have a better boost of starting or max power. Consider the power needs of the items you need to use with the generator when making your selection. 

All of these generators have a fairly similar running power but the Champion and WEN generators have a peak of 3100-watts and the Coleman peaks at 3500-watts. 

Size and weight

If you intend to use the generator in an RV, on a camping trip or other outdoor adventure, you want it to be light and compact. Some are much heavier and larger than others. If you want to have a portable generator, ensure it is light or at least has wheels and a handle. If it is to be used in an RV or similar environment check the size of the space that is available and check the dimensions carefully. Remember that it has to have a bit of space to breath and you need room for the outlets and connections. 

The Generac generator is one of the more compact and lightweight options available. 



Noise is often an issue with generators. If it is too loud it will disturb you and those around you. You want to be able to enjoy the benefit of power without the noise of a loud generator. Fortunately, most 3000 watt generators are inverter generators which are pretty quiet. 

The sound is measured in decibels (dBA). Consider where and how often the generator will be used and give some thought to how much noise it will make.  

The Yamaha is designed with a cover of sound-absorbing materials to reduce noise output. 



Prices can vary from highly affordable to somewhat expensive. Obviously quality does cost a bit so avoid the ultra-budget options from unknown companies. These often lack good support and are sometimes of questionable quality. Having said that, there are a number of generators that work well and offer great value for money. 

The Coleman generator is the best option if you are on a really tight budget. 


Start technology

In the past generators were often quite difficult to start. Modern generators are fortunately much easier. The most common technology used is a recoil pull start. Some models have an electric start sometimes even with a remote control option to start the generator from a distance. It is still important to have a recoil starts as a backup in case of a flat battery or other problems starting the generator. 

The Champion and WEN generators both sport a convenient remote start.

Outlets available

You want to have a few options when it comes to outlets. The primary outlets you will find on most generators are a pair of typical household 120V outlets. For RV use you will want an RV ready twist-lock outlet. For appliances or equipment with higher power requirements, a 240V outlet is handy. USB outlets and 12V charging outlets are also very useful. 

The Champion, Briggs and Stratton, Wen and Generac all offer handy USB ports. 


Ease of use

Wase of usehile some generators can cause frustration, most quality inverter generators are easy to use. LCD displays, in particular, make control and management a breeze. They are also able to display warning and service related information for the safety and reliability of the generator. 

A good example is the user-friendly control panels found on the Yamaha, Generac, Atima, and Champion generators. 


Run time

This is determined by the fuel tank capacity as well as how efficient the generator is. Obviously, the more power you are consuming the more fuel you will use and the faster it will run out. 

A generator running at full capacity will run out much faster than one with a lighter load. For comparison, most runtimes are measured at a quarter or half capacity. Ensure you are reading the specs correctly when making a comparison. 

While they are generally quick and easy to fill up, the last thing you want to do is run out of fuel. Remember that a longer run time does not necessarily mean that the generator is more efficient. It might simply be that it has a larger fuel tank. This might mean that you need to carry more fuel with you and the cost might also be a factor. 

The Xtremepower US will deliver an exceptional 15 hours at a half load or 30 hours at a quarter load. 


Parallel ready

Some appliances or environments might need more power than a 3000-watt generator can offer. Many of these generators allow you to connect another generator in parallel to increase the power output. Generally, these need to be the same or similar generators. A parallel cable is needed and these are normally purchased separately. 

The WEN and Firman generators are some of the options with this feature. 


Safety features

You want to ensure the generator is safe and most 3000-watt generators are perfectly safe to use so long as you use them correctly. Most will have a low-oil warning and shutdown to protect the engine and prevent overheating. The outlets are grounded to ensure the power is not overloaded and to protect from surges. 


Some generators are designed and built with greater durability than others. It is a tricky aspect as additional durability might increase the size and weight of the generator. If it is fixed in position in an RV this might not be a huge factor but if you will move it around often you want one that will handle the odd bump. 

The durability of the engine is also important. Names like Honda and Yamaha are known for outstanding engine durability and will last many years. That is not to say the other makes are inferior and many of them have exceptional engines that will go on for many years. 

The Honda, Yamaha, Atima and Briggs and Stratton generators are all examples of tough and durable options.

A decent warranty demonstrates that the manufacturer has confidence in the quality and durability of their product. That is not to say that all generators with a low warranty are inferior but it is worth looking into when making an investment. 

You want to ensure that you are covered for any defects or breakdowns for at least a few years after purchase. Both the Yamaha and WEN generators have a good 3-year warranty. 



We have reviewed some of the leading options for people looking for a 3000-watt inverter generator. We only looked at the best makes and models that have proved themselves in the market. Everyone has different needs so it is important to find the best one for you.
