The portable power of 4500 watt generators is helpful but they can get noisy. Discover the quietest quality models on the market.

  1. Westinghouse iGen4500 – Quietest and best overall 4500 watt generator (rated 52 dBA)
  2. Powerhorse LC4500i (rated 57 dBA)
  3. WEN 56455i – Budget-friendly quiet 4500 watt generator (rated 58 dB)
  4. Yamaha EF4500iSE (rated 58-60 dBA)
  5. Champion 200986 4500 (rated 61 dBA)

Something important to note is that generator brands don’t always use the same standards when listing their noise levels.

At the same time, besides investing in a warehouse of 4500 watt generators, there is not much else to use to create a list of the quietest models besides manufacturer and customer mentions.

In this category, the quietest model also happens to be the best 4500 watt inverter generator.

So if you want a quiet and quality model with this power level, the Westinghouse iGen4500 is likely the generator for you.

Quietest 4500 watt generators performance on a score of 10 in important categories*

*Compared to similar generators and sometimes based on customer input

1. Westinghouse iGen4500

The Westinghouse iGen4500 is the quietest 4500 watt generator I could find.

Since this is also the best generator in this category, your decision should be relatively straightforward unless you don’t like the Westinghouse brand for some reason.

Westinghouse iGen4500

A normal conversation is about 60 dB so any generator with fewer decibels can be considered quiet.

This definitely includes the 52 dBA (dB converted to human experience) of the Westinghouse iGen4500.

Pros

  • Quietest 4500 watt generator with rated 52 dBA
  • Westinghouse iGen4500 offers 4500 starting watts, 3700 running watts, 30 amps, and 120 volts.
  • Also available with dual fuel
  • Long run time of 18 hours at 25% load
  • Less than 3% THD
  • A lot of performance tracking metrics
  • Optional remote start or CO sensor
  • Weight of 104.7 lbs (47.5 kg)
  • Relatively positive customer reviews
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • Navigating bumpy terrain can be inconvenient
  • Some customers find changing the oil challenging

Besides the noise levels, the Westinghouse iGen4500 also has an impressive run time, number of running watts, number of customers, and much more.

You would expect that all this quality and customizability comes at a high price.

However, this quiet generator is very good for the money too.

One thing you do want to keep in mind is that some customers find that the design makes changing the oil harder than it should be.

That being said, this will likely not stop you from agreeing that the Westinghouse iGen4500 is the best quiet 4500 watt generator for camping, tailgating, and more.

2. Powerhorse LC4500i

Powerhorse LC4500i

The Powerhorse LC4500i may not be quite at the level of the Westinghouse but with 57 dBA at 7 meters with 25% load, you can definitely still call this a quiet 4500 watt generator.

Two other potential reasons to consider this option are the extra low THD of less than 2% and the electric start.

That being said, you also have to know that the Powerhorse LC4500i did not reach our list of the best 4500 watt inverter generators.

This is still a solid generator but it is not quite at the level of the alternatives for a few reasons.

Pros

  • Powerhorse LC4500i offers 4500 starting watts, 3500 running watts, 30 amps, and 120 volts.
  • Relatively low noise levels with 57 dBA
  • Less than 2% THD
  • Has electric start
  • Light weight of 99 lb (44.9 kg)
  • Relatively positive customer reviews
  • 2 years limited residential and 90 days commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • Navigating bumpy terrain can be inconvenient
  • Relatively “short” run time of 10 hours at 25% load
  • Relatively short commercial warranty
  • A few technical issues here and there, including with the electric start
  • Not that fuel-efficient

For example, the run time on a full tank of gas of 10 hours at 25% load is definitely below average when it comes to 4500 watt generators.

Together with the few cases of technical issues and average performance you will likely just prefer other options.

Even if you like the electric start, there are other 4500 watt generators that offer this. Seemingly with fewer cases of defects.

Since these last few paragraphs do sound a bit negative, I do want to emphasize that the Powerhorse LC4500i still is a relatively solid and quiet option.

3. WEN 56455i

WEN 56455i

Besides being relatively quiet with 58 decibels at 25% load, the WEN 56455i is also one of the most budget-friendly quality 4500 watt generators.

Sometimes I like to switch up the order in the quietest generator lists since a few decibels is often worth the extra quality.

The WEN 56455i is just not quite there yet with the low number of customers and how good the top pick is anyway.

Having customers before you can help uncover any potential defects and gives you just a bit more confidence that you will get a quality generator.

Pros

  • Relatively low noise levels with 58 dB
  • WEN 56455i offers 4500 starting watts, 3500 running watts, 29 amps, and 120 volts.
  • Nice run time of 8.5 hours at 50% load
  • Also available with dual fuel
  • Good fuel efficiency
  • Produces clean power thanks to inverter technology
  • Weight of 99.2 lb (45 kg)
  • 2 years limited residential and 90 days limited commercial warranties
  • Budget-friendly

Cons

  • Navigating bumpy terrain can be inconvenient
  • Relatively short commercial warranty
  • Not a lot of customers yet

At the same time, it is definitely worth mentioning that the WEN 56455i could be the right choice anyway for people on the budget.

With how well the WEN brand does with their other generators you do get the impression that this option could battle for the best quiet 4500 watt generator for the money.

At least for residential situations since the commercial warranty is on the shorter side.

4. Yamaha EF4500iSE

If you only look at the sound levels, customer reviews, and features, you would almost invest in the Yamaha EF4500iSE.

That being said, there will not be many people that find the 58 to 60 dBA at rated load and other features worth the really big price jump over other options.

Additionally, even if you get your hands on one, this quiet 4500 watt generator still uses a relatively high amount of fuel and has a weight that is challenging to move around.

Pros

  • Yamaha EF4500iSE offers 4500 starting watts, 4000 running watts, 30 amps, and 120 volts.
  • Relatively low noise levels with 58 to 60 dBA
  • Nice run time of 15.2 hours at 25% load
  • Has electric start
  • “Inverter ensures high-quality electricity”
  • CO sensor
  • Weight of 194 lb (88 kg)
  • 3 years limited warranty
  • Very positive customer reviews

Cons

  • Navigating bumpy terrain can be inconvenient
  • Not that fuel-efficient
  • Very expensive compared to other 4500 watt generators

The things above still apply but you may not mind investing more in a high-quality generator.

When it comes to 4500 starting watt generators the Yamaha EF4500iSE stands out with its 4000 running watts.

It is also just hard to find reviews of customers who had any issues with this model which is generally a good sign.

In short, the Yamaha EF4500iSE is high-quality and quiet but at this price point, many people will prefer one of the other quietest 4500 watt generators.

5. Champion 200986 4500

Champion 200986 4500

With how silent the previous options are it can be easy to forget that the 61 dBA of the Champion 200986 4500 is still about as quiet as a normal conversation.

On top of that, this generator is also a solid option with many happy customers, good fuel efficiency, and the option to choose a dual fuel model.

Because of this combination, you could argue that the Champion 200986 4500 is just a bit better than the Westinghouse iGen4500 for people who want to play things safe for home backup power.

That being said, the Champion 200986 4500 is not perfect either. While this is somewhat normal, there are still a few exceptional cases of technical issues.

Pros

  • Relatively low noise levels with 61 dBA
  • Champion 200986 4500 offers 4500 starting watts, 3500 running watts, 30 amps, and 120 volts.
  • Also available with dual fuel
  • Nice run time of 14 hours at 25% load
  • Nice fuel efficiency
  • Less than 3% THD
  • Weight of 95 lbs (43.1 kg)
  • Very positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers

Cons

  • Navigating bumpy terrain can be inconvenient
  • A few exceptional cases of technical difficulties

Besides the things above, the Champion 200986 4500 has solid run times, THD, warranties, portability, etc.

In short, if you just want a quiet 4500 watt generator for (RV) camping, tailgating, and other simple outdoor activities, you will likely prefer the Westinghouse iGen4500.

On the other hand, people who want a silent generator to rely on for backup power could still consider the Champion 200986 4500.

Especially if there are any good deals.
