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.

3. Generac GP3000i with PowerRush Technology – Amazon's Choice

Features

  • Running Watts: 2,300 watts
  • Surge Watts: 3,000 watts
  • Fuel Type: Gasoline
  • Tank Size: 1.06 gal
  • Start Type: Manual recoil system
  • Runtime: 5.8 hrs @ 1/4 load
  • Noise Level: N/A
  • Weight: 59.5 lbs

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.

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.
