Factors That Influence a Used Generator’s Worth 

The worth of used generators is widely influenced by different factors. These factors include:

1. Age of the Generator 

The age of the generator is one of the most significant factors a seller will look at before selling their generator, which is also a factor affecting its worth. That’s to say, a generator that is still new and hasn’t spent many years will generally have a higher value and price than an older generation.

Therefore, if you’re buying a used generator that hasn’t been used for a long time, you should expect it to be worth more than others. But sometimes that’s not the case — older generators tend to cost more than new generators cause of how reliable and durable they are over the past few years.

2. Condition of the Generator 

Secondly, the condition of the generator is another critical factor that determines the worth of used generators. I do sell used generators and if others are to buy them, I tell them “if they want me to repair or service the generator to be working like a brand new generator, which will cost them higher than the expected price.”

But if they’d like it that way, they can get it at the lower and normal price. That’s because a generator that has been well-maintained by the seller and is in good working condition and doesn’t have any faults will have a higher value than one that has been poorly maintained or has been damaged.

3. The Generator’s Brand and Model

Some generator’s brands have already proven to be known for their reliability and durability. So, most generator users turned out to have higher interest in them.

If you’d want a used generator that’s well known just like the Generac, Cummins, Honda, etc, be ready to buy it at a higher price than lesser-known generator brands.

4. Features of the Generator 

The output and fuel type of the generator you want to buy also greatly influences the worth. For instance, a generator that’s 15kw will worth less than a generator that’s 25kw.

Additionally, if you’d want to buy a used standby generator, you should also expect it to cost more than a used portable generator. Because of their size, fuel type, and power output.

5. Demand in the Local Market

Finally, the demand for generators in your local market can affect their worth. There was a time in my area where there was a power outage for more than a month. 

Many construction workers were already tired of renting generators, hence they opted for used generators that can power their equipment and mostly diesel generators.

These made the price of diesel generators higher I’m my area and as a result of that, they became hard to find. We had to move to another state — areas with low demand for used diesel generators to buy. 

Where to Find Used Generators

Looking for a used generator can be a challenging and frustrating task; however, fortunately, there are several ways to locate one. Here are some options you can consider:

Firstly, one option is to use online marketplaces like eBay, Craigslist, and Facebook Marketplace to find used generators. However, before purchasing it, do your research thoroughly and inspect the generator to ensure that it meets your requirements.

Another good source for used generators is local classifieds, such as newspapers and community bulletin boards. Before buying, make sure to inspect the generator and negotiate the price with the seller.

Moreover, generator dealers often sell used generators and can provide warranties and maintenance plans for their products. Although buying from a dealer may be more expensive than buying from an individual seller or owner, they can provide you with the best generator that meets your needs, given their professional experience and knowledge in generator maintenance and services.

Lastly, you can ask friends, family, and colleagues if they know of anyone selling a used generator. This can be an effective way to find a generator that has been well-maintained and in good condition.

Ways to Research Seller and Inspect Used Generator

When considering purchasing a used generator, you do your due diligence and conduct a thorough investigation to ensure that the generator is in good condition and meets your requirements. To achieve this, there are several steps that you can follow.

Firstly, research the seller’s history and reputation before making any commitments. This can be done by checking online reviews, asking for references, and looking for any negative feedback or complaints. By doing so, you can get a better sense of the seller’s credibility and whether they have a good track record.

Secondly, check the generator’s maintenance records. These records will provide you with valuable information about the generator’s history, including any repairs or maintenance it has undergone. By reviewing these records, you can gain insight into the generator’s condition and whether it has been well-maintained.

Next, conduct a physical inspection of the generator. This should involve looking for any signs of wear and tear, rust, or damage. Additionally, you should check the oil and coolant levels, examine the engine and electrical components, and look for any leaks or cracks in the generator’s casing. By doing so, you can get a better sense of the generator’s overall condition and whether it’s in good working order.

To test the generator, you should start it up and run it for a few minutes. This will allow you to check for any unusual noises or vibrations and ensure that the output voltage meets your requirements. Additionally, you should be on the lookout for common problems, such as rust, wear and tear on the engine, damaged electrical components, and leaks in the fuel or cooling systems.

By following these tips and strategies, you can research the seller and inspect the used generator with confidence, knowing that you’re making an informed decision. Remember to take your time and thoroughly inspect the generator before purchasing it to avoid any potential problems down the line.

How to Negotiate the Price of Used Generators 

When it comes to purchasing a used generator, negotiating the price can be a tricky task. However, with some practical tips and techniques, you can negotiate a fair price that fits within your budget. Here’s what you need to know:

First and foremost, it’s crucial to research the market prices of the generator you’re interested in. Look at online classifieds, auction sites, and dealer websites to get a sense of the typical price range for the model you’re looking at. By doing so, you’ll have a realistic idea of what to expect and be better prepared to make a fair offer.

In addition, it’s important to determine your budget for the generator. This should include any installation or maintenance costs. Having a budget in mind will help you negotiate effectively and avoid overspending.

Next, when inspecting the generator, look for any signs of wear and tear or damage. Note any issues that may affect the generator’s performance or lifespan, and use this information to negotiate a lower price if necessary.

Once you’ve inspected the generator, it’s time to make a fair offer. Based on your research and inspection, make an offer that takes into account the market value of the generator, its condition, and your budget. Be prepared to justify your offer with specific details about the generator’s features and any issues you’ve observed.

If the seller doesn’t accept your initial offer, be prepared to listen to their counteroffer. Consider their perspective and be open to negotiation, but don’t feel pressured to accept a price that exceeds your budget or the market value of the generator.

In case you and the seller are close to reaching an agreement on price, consider negotiating additional terms, such as a warranty or maintenance agreement. These can add value to your purchase and provide you with additional peace of mind.

Finally, once you and the seller have reached an agreement, make sure you finalize the details of the sale in writing. Include the agreed-upon price, any additional terms, and a clear understanding of the payment and delivery process.

By following these tips and techniques, you can negotiate the best possible price for a used generator while also ensuring that you’re making a fair and informed purchase. 

Remember to approach the negotiation process with a clear understanding of your needs and budget, as well as a realistic understanding of the market value of the generator you’re interested in.


If you’re in the market for a generator but don’t want to pay the high price of a brand-new model, consider buying a used one instead. 

Used generators can offer significant cost savings, while still providing reliable power when you need it most. However, it’s important to do your research and make sure you’re buying from a reputable seller, to ensure that you’re getting a quality product that will meet your needs.
