Reviews for Cat Portable Generators

"anything with the CAT logo is worth taking a second look."

— Generator Power Source

"The Caterpillar generators are an excellent choice according to most owners. They have enough power to work well in virtually all situations whether you are working or playing. These machines are durable and dependable power sources. They set up easily and work without issues, right out of the box.

They are also very popular for their ability to operate quietly, which is something most other generators cannot do. Perhaps that is why they all hold a rating of 4+ stars."

Cat RP7500 E: "If you want big power generation and a boatload of features...you’ll be satisfied."

— Sensei

"It was designed primarily for construction sites, so it comes with an increased level of power generation and commensurate decibel levels.

This isn’t the generator you’ll want to go with if you need something small and stealthy. If you want big power generation and a boatload of features, though, you’ll be satisfied with this offering from CAT."

Cat RP12000 E: "This is one heavy-duty portable generator."

— HouseholdMe

"This is one heavy-duty portable generator. The Cat RP12000E Gas Powered Portable Generator 502-3699 is user-friendly and safe enough to use for household electricity needs yet tough and powerful enough to withstand rough handling on job sites.

With its extra-large gas tank and V-twin engine, you can run appliances, power tools and electronics for half a day. Although it’s gasoline powered, the generator has an electric-start dial and LED panel for quick startups and night visibility."

CAT INV2000: "Excellent features make this a great buy for your money."

— Chainsaw Journal

"CAT equipment has always been associated with heavy-duty machinery, usually seen on large construction sites. They’ve recently ventured into the domestic user market, producing more affordable generators that are not designed for the same applications as their industrial machines."

"Cat Generators Reviewed – Are They Any Good?"

— Generator Advisor

"Caterpillar is the brand which does not need a long introduction. If you’ve ever visited any construction site in the US you’ve probably noticed that most of the heavy-duty machinery used there is all manufactured by Cat.

What few people know though is that Caterpillar also makes portable generators. In the following article, we’re gonna have a look at some of the Cat generators and see whether they really live up to the reputation of the brand and how do they perform against other generator brands."
