Our Top Inverter Generator Picks
The Westinghouse iGen4500 has been around for a while but it still ranks at the top in our book. It is powerful, compact, quiet and capable of running for a long uninterrupted time.
Getting this generator running is a breeze since it has both a remote start and an electric push button start. It is already ready for use in an RV thanks to its TT-30R outlet while still leaving plenty of opportunity for connecting other devices via the USB ports or two AC outlets.
At the top you find the opening for the 3.4 gallon fuel tank which when full is enough to keep this inverter running for up to 18 hours on a quarter load. That should be enough electricity for the basics such as lighting and an energy-efficient refrigerator.
On a campsite you won’t be bothering the neighbors in the least because the iGen4500 runs very quietly. It is also the perfect design for travelling – it is a compact square shape outfitted with small wheels and a telescopic pulling handle.
This Pulsar inverter generator is very similar to the Westinghouse iGen4500 with only slight differences in its specs. The Pulsar model has slightly less power and runs more loudly but it does have a better fuel economy.
It has the same fuel tank size but runs more efficiently since this Pulsar inverter generator reaches up to 15 hours on a half load. That is a very impressive feature for an inverter generator.
We also like that it comes with a remote start so you can place it at a comfortable distance where the noise won’t be as bothersome. Still, it still runs quieter than any conventional portable generator.
It has many different outlet types making it suitable for anything from RV trips to tailgating or even as an emergency backup generator for homes. The rear wheels and telescopic handle means it is more than easy to move.
We completely understand why the Generac GP3000i is a top rated inverter generator online. It is much more lightweight than you would expect for its power making it a great travel companion.
This is an upgraded version in the popular Generac GP series since it has PowerRush Technology pre-installed. PowerRush Technology is what allows for a higher peak watts which comes in handy when larger electric appliances are connected.
On the control panel you will find two 20 amp AC outlets, an RV ready outlet and two USB ports for connecting sensitive devices such as laptops and cameras. There is no data center on the control panel so you will have to pay close attention to what is connected.
Given it has such a small fuel tank, the run time is somewhat limited. Expect around 6 hours on a quarter load and 4.5 hours on a half load.
WEN is a generator brand that delivers great deals in terms of value and the WEN 56380i is a great example. This unit has a price tag that is several hundred dollars lower than its competitors with the same output.
Not only is it the most powerful option on our list of the best inverter generators but it also has a great fuel economy. On its own it already delivers plenty of power but when joined in parallel capacity the output is enough to power smaller households in emergencies.
We highly recommend this unit if you are in need of quite some power but don’t want to deal with the weight, noise and unstable electricity of a conventional portable generator.
5. Champion 3400-Watt Dual Fuel Inverter Generator – Most versatile
Dual fuel generators are great because it gives you more options. You can choose the type of fuel that is more economical and readily available which can make a big difference in running costs and emergency preparedness.
There are very few dual fuel inverter generators but it is not surprising that Champion Power Equipment manufactures one. Champion has always been known as a very innovative brand.
This model is a perfect example of craftsmanship and smart engineering. From its high performance output to its user-friendly details, it is a fantastic and highly recommended inverter generator.
If you are looking for amazing quality at a fair price you won’t be disappointed by the Firman generators. This US manufacturer with a production plant in Arizona spends extensive time on research and development so that each of their designs run beautifully and are user-friendly.
The first thing we noticed about the Firman W03083 is that it is extremely energy efficient. With a relatively average fuel tank it is still capable of running for 9 hours on a quarter load.
We also like how its continuous power is only 300 watts lower than its peak power which is a rare achievement on any generator. On top of that, its noise level remains below 58 decibels for greater comfort.
This is a durable design with an outer casing that keeps all dirt, dust and debris away from the engine and internal parts. It is one of the best inverter generators made in the USA.
One of the main reasons to buy an inverter generator is that they are the best in terms of portability. That especially rings true with this Rainier R2200i which weighs in at just 44 pounds.
This is a great choice for camping since it can be carried in one hand and runs very quietly. It also has a good fuel efficiency so you don’t have to carry as much extra fuel.
On eco mode the fuel efficiency is even better since it automatically adjusts to the current load. You can also get twice the power by making use of its parallel capability and connecting a second unit.

If you are trying to keep the weight to a minimum during travel then this Tacklife model is the best inverter generator for you. It weighs less than 40 pounds so even bringing along a second unit would not weigh you down much.
This is a smaller capacity unit but it still holds enough power for most sensitive electronics like mobile phones, laptops, lighting and smaller household appliances. There are plenty of outlets for connecting several devices at once.
One downside is the limited run time but that is expected with the small fuel tank. Thus, this is only suitable for light use and for a shorter run time.
Inverter generators are a popular choice for use in an RV and the Yamaha EF2200iS is one of the most popular options. It is a compact design with three carrying handles making it extra portable.
Yamaha has always been a popular brand for power equipment because of their excellent engines. The EF2200iS further supports that reputation since it is fuel efficient, runs reliable and has a smart throttle for that automatically adjusts to the current load.
We like that this unit includes a DC outlet for charging batteries which is a very welcome feature on RVs. Of course, it also has an RV ready outlet and a digital monitoring display.
