This generator is covered under a 3-year limited warranty with free lifetime technical support. With a nationwide network of service and support from dedicated experts, this warranty is unbeatable.

Having a warranty and free lifetime technical support from a network of service centers is standard with most Champion power equipment. Champion Power is committed to providing great service, so any of their nationwide service centers will back the warranty.

Customer Ratings and Reviews

Reviews for this piece of Champion Power equipment are overwhelmingly positive.

Let’s start with the negative reviews online about the generator. To begin, there is no electric start. Some people also say that the generator is loud. However, at 3500 running watts, you can expect it to be a little loud. The generator has a noise level of 68 dba from 23 feet, which is actually quieter than a modern-day vacuum cleaner. It might be loud for some, but it’s really up to you to decide if the noise level is too much to handle.

One other negative review about this generator is that it doesn’t have a wireless remote start like its big brother, Model #100433. Although having a wireless remote start would be a convenient feature, most of the time you might want to be there to start your generator in person. It’s disappointing to not have the wireless remote start option, but keep in mind that this is a more budget-friendly generator. Wireless remote start is an expensive feature to have, so it makes sense that this unit doesn’t have it.

Moving on from the lack of a wireless remote and the noise level, let’s move on to the positive reviews On Amazon, the product has a 4.6/5 star rating based on 2.8k reviews. From other sites such as Harbor Freight Tools,, and Tractor Supply Co., the ratings don’t dip below 4 stars.

Some of the most popular points made in reviews across the web include the oil shut-off sensor. People love that the generator is “smart” enough to know when it has low oil and that it’ll shut off if it needs to. In these same reviews, people also enjoy the built-in surge protector that prevents overloads and keeps appliances and equipment safe.

Others rave about the limited warranty and free lifetime technical support. People enjoy that it includes 3-year limited warranty so if any parts become damaged or break, Champion Power Equipment will work with them to get the problem fixed. Finally, people love the Intelligauge system that keeps you updated on the voltage frequency and operating hours.
