We have plenty of reviews discussing the best portable generators. Opinions will vary, so there can be no definitive top choice. We researched customer ratings on Amazon, and similar sites, in great detail to find out what the buying public considers the number one portable generator.

Analyzing customer reviews is a skill I’ve developed over many years of writing about power equipment. We cannot simply look at the number of stars. A new product may have a 5-star rating on the Amazon, Lowes, or Home Depot websites. That’s easy enough to achieve if there are only a few customer reviews. Three five-star ratings from three reviews look fantastic at first glance. Though this is not really a conclusive overview of the product. The best measure only comes into effect after 1,000 ratings or more. This gives us a better idea of how the majority of generator buyers feel about a particular model.

Taking things a step further, we cannot say which is actually the best portable generator without reading the reviews. I always look for common complaints or compliments. If the overwhelming majority of customers point to a certain defect or alternatively,  something fantastic, we can safely assume this is true.

5-star rating on amazon

This is how I set about determining which are the best rated portable generators. Firstly, the products need to have at least 1,000 customer reviews. To qualify, over 90% of the ratings have to be 4 – 5 stars. I’m not going by my personal opinions or my knowledge of the machines. Not an easy thing to do. I always have a lot to say about generators. This compilation of top-rated portable generators is based entirely on the views expressed by people who have bought the products and shared their experiences.

I don’t totally agree with all the choices. Then again, it’s easy to pick the very best generator when you’re reviewing it and not actually buying it. Often a cheaper generator will be more popular and will receive more reviews than the really expensive models. It’s probably more realistic to check what people are actually buying and how they feel about their purchase.

I can certainly agree with the number one customer’s choice for the best portable generator. I’m not at all surprised to see the Honda EU2200i emerging as the most acclaimed portable generator. I always mention it as the benchmark by which I compare all compact, quiet inverter generators. It is far from being the cheapest, but not exorbitantly expensive. I can fully understand why this is the generator buyer’s top choice.

I will not be reviewing any of the top 5 generators featured in this article. Only basic specs and a summary overview will be provided for each model. Click on the links to the complete generator reviews, if you want to read more about any of the models mentioned.

This article is merely a guide to which generators have received the best customer ratings. Reading the full review will provide a better understanding of what the generator has to offer. The popular choice may not be the perfect fit for your needs, so a comprehensive generator review will help you make a more informed choice.

In the end, all the work is done for you. This guide provides a great insight into what people want. Clicking on the link to the full review will offer all the information you could possibly need before buying any of these great generators.
