The Best Inverter Generator Reviews

The Best Inverter Generator Overall: Honda EU2200i

[compareProducts display=”vertical” ids=311]

Full review here >>> Honda EU2200i Review

We’ve chosen the Honda EU2200i as the best inverter generator available now. The successor to the EU2000i (itself, until recently, our favorite generator), the EU2200i is even better value...

However the EU2200i had some stiff competition – the Yamaha and Champion models are also pretty good – but the Honda won mainly due to the features you get for the money.

In particular we were impressed with

  • the over 8 hours run time per tank of gas
  • how easy it is to maintain
  • its ability to power even the most energy hungry appliances such as TVs and fridges.
  • the wide selection of certified repair shops, vital if you have a problem whilst out and about.

It is, however, one of the priciest generators – but worth it.

The Best Budget Inverter Generator: DuroStar DS4000S

Full review here >>> DuroStar DS4000S Review

The DuroStar DS4000S portable inverter generator is a the cheapest generator we reviewed at under $300.

As you might expect it doesn't have many of the great features of the more expensive models, especially the Yamaha EF2000iS and Honda EU 2000i.

But it does provide a (reasonably) portable experience, 8 hours running time with a high power outage.

The Best Portable Inverter Generator: Yamaha EF2000iS

Full review here >>> Yamaha EF2000iS Review

Japanese electronic devices are famously easy to use and beautifully simple in design. This fresh offering from Yamaha is no exception; their top of the line, notably fuel efficient generator has a peak wattage of 2,000 / 1,600 running wattage. The engine is able to shed heat, so that it doesn’t build up and manages to stay very cool while running.

At $990, this option is considerably more expensive than many that are produced within the United States of America, but Yamaha has a repeatedly validated reputation for being a worthwhile investment. If maintained properly, the longevity of this engine, accompanied with the incredible fuel economy, combine to make the EF2000iS worth every penny of the cost.

This generator carries the rare ability to run at least twenty four hours at a full load and not show the faintest sign of slowing down or succumbing to malfunction. By industry professionals, campers, and others who have experienced this product, it is revered as being one of the most reliable generators on the market.

Features include an electrical overload breaker, which prevent the damage that can occur in many generators from unexpected electrical overload; this is a handy addition, but many owners claim that the slick power of this generator creates an experience where these overloads are very rarely threatening to occur.

The engine comes to life gracefully with a gentle pull of the recoil coil cord, and runs so smoothly and quietly that many have said that it is at least twice as quiet as comparably priced generators, even at a full load. It also comes equipped with Pulse Width Modulation control inverter technology.

This is one of the most stunning, mechanically sound, and generally dependable inverter generators on the market. Consider adding this tool, which represents the best in Japanese innovation, to your repertoire; either as a backup generator for around the house our out on the open road and into the wilderness with your camper, RV, or boat.

The Best Alternative To Yamama ef2000is: WEN 56200i Super Quiet 2000W

The WEN 56200i Super Quiet 2000W portable inverter generator is a cheaper alternative to the Yamaha ef2000is. It boasts many of the features of the ef2000is but at around half the price.

The unit runs at only 2000W and so is more appropriate for outside use rather than as a home back up power source. It is portable and quiet, and has a 9.5 hours running time, making it perfect for camping and RV power generation.

The other key feature it shares with the Yamaha is fuel efficiency.

Buying the Wen is also a great way of getting many of the benefits of the Yamaha ef2000is for less. Wen does not have the same brand recognition as Honda or Yamaha. Yet it produces products of the same high quality.

You could thus buy two Wens for the same price as the Yamaha and generate twice the power. Indeed the 73536i has stacking technology to enable such a set up.

In summary then, the Wen 56200i is a great alternative to the Yamaha ef2000is. This is especially the case for campers and RV owners on a budget or not concerned with brand.

Generac iQ2000 – 1600 Watt Portable Inverter Generator

Generac has created a well-priced, quiet, clean, and effective competitor to market leaders with their iQ2000-model inverter power generator. At $800, this is really is an ideal generator for the average person with small electrical power needs.

Generac’s iQ2000 has been third party tested and proven to be quieter than Honda, and this comparative quietness makes it the perfect companion for those who use their generators in the great outdoors and are wanting to savor the sounds of the wild. Yes, it is very quiet, reliable, and simple to operate, with a fuel economy that is truly commendable.

A major factor to its convenience is that it this ultra-lightweight option weighs under fifty pounds, which makes it very portable, and a wise choice for camping or tailgating. The design was precisely engineered for the main purpose of being low maintenance and portable for travel.

This generator offers three engine speeds (Economy, Standard, and Turbo), which are easily changeable according to your needs, and make a significant impact in keeping a quiet volume and limiting the rate of burning through fuel. It has also been designed for easily accessible parallel capability, allowing one to double the power without sacrificing portability.

Not only is this an innovative generator for its slick design and enviable lack of sound pollution, but those who purchase this inverter generator will also reap the benefits of a LED dashboard which is intuitive and communicative, which clearly shows important information such as remaining runtime, wattage use, and fuel level status.

This option comes with a limited three year Residential and Commercial Warranty.

Briggs & Stratton 30651 P2200 PowerSmart Series 2200-Watt Inverter Generator

This quiet and fuel efficient generator produced 2,200 starting watts and 1700 running watters. As well as being suitable for camping, tailgating, and use in the RV, it is also safe for laptop computers, TVS, and other household electronics, which is not true of all of its competitors.

It is not the quietest option, but it is an effective machine for the price and it packs a lot of power. It also comes equipped with a USB port. Weighing in at about 52 pounds, this generator is designed for portability and easy transport.

This is an affordable option, priced at about $630, and is well suited for parallel capability if you would prefer to have double the power. This is quite a good deal for 4400 Watts, as a single 3000-Watt version of this same general model available for just under double the price. This model can also partner with the 3000-Watt version.

Generally speaking, this is a great option if you are conscious of how much you are spending, and will reliably provide and deliver a lot of portable power.
