generac vs duromax generator


Having a generator is absolutely essential, especially if you live in an area where power outages are common. In times of emergency, a generator can be a lifesaver. But with so many brands and models on the market, it can be overwhelming to choose the right one. In this review, I’m going to compare Generac and Duromax, two of the most popular generator brands out there, to help you make an informed decision.

Generac vs. Duromax

Let’s start by comparing the prices of the two brands. Depending on the model, Generac generators can be quite expensive. In comparison, Duromax generators are more affordable, making them a good option for those on a tight budget.

When it comes to durability and build quality, Generac definitely has the edge. They are known for producing high-quality generators that are built to last. Duromax generators, on the other hand, may not have the same level of build quality and may not last as long.

In terms of engine performance and power output, both Generac and Duromax are similar. They both produce enough power to run essential appliances during a power outage.

When it comes to maintenance and repair, Generac generators are generally easier to maintain and repair than Duromax generators. Generac also has a better reputation for customer service and support.

Noise levels are another factor to consider. Generac generators are generally quieter in operation than Duromax generators. This can be an important consideration if you live in a densely populated neighborhood or have neighbors nearby.

Finally, run-time on a full tank of fuel is important to keep in mind. Generac generators are known for having longer run-times than Duromax generators. This means you won’t have to refuel as often and can have peace of mind during longer power outages.

Pros and Cons of Generac and Duromax

Let’s take a closer look at the pros and cons of each brand.

Pros of Generac

  2. Availability of spare parts: Generac has a large network of dealers and repair centers, making it easier to find spare parts when needed.
  3. Better engine performance: Generac generators are known for producing more power and running more efficiently than Duromax generators.
  4. Quieter in operation: Generac generators are generally quieter than Duromax generators, which can be important in residential areas.

Pros of Duromax
  1. Affordable price point: Duromax generators are generally more affordable than Generac generators, making them a good option for those on a tight budget.
  2. Equal performance to Generac: Duromax generators can produce the same amount of power and run just as efficiently as Generac generators.
  3. Long-lasting fuel: Duromax generators have a reputation for being fuel-efficient and using less gas during operation, which can save you money in the long run.
Cons of Duromax

  3. Less reliable: Some users have reported reliability issues with Duromax generators.

Final Thoughts

When it comes down to it, Generac is the better choice for those who want a high-quality, reliable generator that will last for years. However, if you’re on a tight budget, Duromax could be a good option as long as you’re willing to compromise on build quality and durability.


A generator is an essential tool to have, especially in times of emergency. When you’re purchasing a generator, it’s important to choose a brand that is reliable and durable. Generac and Duromax are two popular brands, but Generac is the better choice for those who want long-lasting quality.
