With this much power, it is only natural to worry about the decibels you will cause. Discover the quietest 12000 watt generators.

Quietest 12000 watt generators top picks

The first thing to note is that there are actually that many differences between noise ratings in the online 12000 peak watt generator market.

This means I mostly considered other quality details when putting together the list below since the first four generators are equally quiet.

  1. Pulsar G12KBN-SG – Quietest dual fuel 12000 watt generator (74 dB)
  2. Westinghouse WGen9500TFc – Quietest tri fuel 12000 watt generator (74 dBA)
  3. Champion 200929 9500 – Quietest gasoline-only 12000 watt generator (74 dBA)
  4. DuroMax XP12000EH (74 dB) (dual fuel)
  5. A-iPower SUA12000E (78 dB) (gasoline-only)

Something else to note is that these are non-inverter generators. If you plan to power sensitive electronics, you likely need an inverter instead.

How we selected our top picks

While the top picks are still the quietest 12000 watt generators available online, I also looked at other things since the decibel ratings are often the same.

Some of these other details I considered when putting together the ranking include:

  • Run time, power capacity, outlets, portability, etc.
  • User reviews
  • Anecdotal reviews from experts
  • Price
  • Brand trustability and reputation
  • The performance categories below

5 Quietest 12000 watt generators reviewed

People who already have a preference for fuel options could find the list of top picks and the table of category performances enough to make a choice.

That being said, the more in-depth reviews of the quietest 12000 watt generators below can help you find the best option for your personal situation.

1. Pulsar G12KBN-SG – Quietest dual fuel 12000 watt generator (74 dB)

The Pulsar G12KBN-SG got the top spot for the quietest 12000 watt generator because it has a dual fuel option, a reasonable price, and other solid features.

Pulsar G12KBN-SG

User tests don’t always confirm this but it is often said that generators tend to be quieter when running on propane.

And even if you notice that the Pulsar G12KBN-SG makes less noise on gasoline, you can just use this fuel type if decibels are your main priority.

The Westinghouse WGen9500TFc below is a solid option too but people tend to be less interested in tri fuel and the slightly higher price.

Pros

  • Quietest 12000 watt generator with 74 dB
  • Pulsar G12KBN-SG offers 12000 starting watts, 9500 running watts, 50 amps, and 240 volts (gasoline)
  • Dual fuel feature so you can run on propane (LPG) too
  • Good run time of 12 hours at 50% load
  • Weight of 209 lb (94.8 kg)
  • Has electric start
  • Relatively positive customer reviews
  • 1 year limited warranty
  • A lot of customers

Cons

  • A few very exceptional technical issues
  • Warranty is not that long

Differences aside, the Pulsar G12KBN-SG has a great run time of 12 hours at 50% load on a full tank of gas.

If the noise levels of this relatively quiet 12000 watt generator are low enough for your liking, you could use the Pulsar G12KBN-SG for things like running an air conditioning system overnight.

One thing that can be better is the relatively short warranty of one year.

There are also a few very exceptional cases of technical issues and a few mentions that 12000 watt generators are supposed to be somewhat loud.

That being said, customers are generally very positive about the Pulsar G12KBN-SG so if you want a good 12000 watt dual fuel generator, this could be the right choice for you.

2. Westinghouse WGen9500TFc – Quietest tri fuel 12000 watt generator (74 dBA)

The Westinghouse WGen9500TFc is the quietest tri fuel 12000 watt generator and just a great option for this power level too.

If you don’t need the option to run on natural gas and/or propane, you can also get this generator in dual fuel or gasoline-only version.

Westinghouse WGen9500TFc

These options tend to be just a bit pricier than the Pulsar G12KBN-SG but any temporary deals can swing this difference the other way.

Additionally, even if the Westinghouse WGen9500TFc requires a slightly bigger investment, it could be worth it thanks to the reliability of this generator.

Pros

  • Noise levels of 74 dBA
  • Westinghouse WGen9500TFc offers 12000 starting watts, 9500 running watts, 50 amps, and 240 volts (gasoline)
  • Tri fuel feature so you can run on propane and natural gas too
  • Run time of 12 hours at 25% load
  • Weight of 203.4 lb (92.3 kg)
  • Has electric and remote start
  • Four GFCI outlets
  • CO sensor
  • Relatively positive customer reviews
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers

Cons

  • A few exceptional shipping issues

You really have to dig deep to find customer reviews that are not very positive about the Westinghouse WGen9500TFc.

Even if you do manage to find a few, these often mention shipping issues like a bent frame. Not something about the generator itself.

This reliability in combination with convenient features like the electric and remote start makes the Westinghouse WGen9500TFc a great home backup power generator.

And in the unlikely case there are any shipping issues, this quiet 12000 watt generator still has solid warranties to fall back on.

3. Champion 200929 9500 – Quietest gasoline-only (74 dBA)

The Champion 200929 9500 is somewhat lower on the list of the quietest 12000 watt generators because you only have the option to try out the gasoline noise levels.

However, if you do not intend to use other fuel types anyway, this model from Champion is basically the most reliable 12000 watt generator available.

Up to the point where the suboptimal customer reviews seem to mostly mention a lack of fuel gauge which Champion already added to the generator.

Pros

  • Noise levels of 74 dBA
  • Champion 200929 9500 offers 12000 starting watts, 9500 running watts, 50 amps, and 240 volts
  • Run time of 8 hours at 50% load
  • Weight of 206 lb (93.4 kg)
  • Has electric and remote start
  • Four GFCI outlets
  • CO sensor
  • Very positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers

Cons

  • Can only use gasoline as fuel

Similar to the Westinghouse, the Champion 200929 9500 has four GFCI outlets, electric and remote start, and a CO sensor.

These features are not unique when it comes to quiet 12000 watt generators but they do add layers of safety and make using the machine more convenient for you.

In short, the Champion 200929 9500 is a great option for people who want a powerful and reliable gasoline-only generator.

Especially if you stumble upon any good deals that make the price-value ratio even more attractive.

4. DuroMax XP12000EH (74 dB)

When investigating the quietest 12000 watt generators you will encounter the DuroMax XP12000EH and very similar generators from DuroMax.

These generators all have a decibel rating of 74 dB with small differences in what fuel you are able to use and what outlets you get.

DuroMax XP12000EH

The DuroMax XP12000EH and its relatives are still solid 12000 watt generators.

However, it is also fair to say there seem to be technical and shipping issues just a bit more often than with the previous options.

Pros

  • Noise levels of 74 dB
  • DuroMax XP12000EH offers 12000 starting watts, 9500 running watts, 50 amps, and 240 volts
  • Dual fuel feature so you can run on propane (LPG) too
  • Good run time of 19 hours at 25% load
  • Weight of 224 lb (101.6 kg)
  • Has electric start
  • Four GFCI outlets
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers

Cons

  • A few cases of technical and shipping issues

Additionally, even with this slightly more suboptimal reliability, these relatively quiet 12000 watt generators from DuroMax tend to be just a bit pricier.

Two details that do positively stand out in these models are the long run time of 19 hours at 25% load on a full tank of gasoline and the number of kWh you get per gallon of fuel.

So while you will likely prefer one of the other options on this list, you could still consider the DuroMax XP12000EH too.

If you don’t care as much about the dual fuel feature, you can also save some money by going for the DuroMax XP12000E instead.

5. A-iPower SUA12000E (78 dB)

The first thing to note is that the A-iPower SUA12000E is actually two decibels louder than the actual quietest 12000 watt generators.

At the same time, knowing about the other generator brands available and their noise levels is more relevant than reviewing four different DuroMax models with tiny differences.

A-iPower SUA12000E

With that in mind, it is also fair to say that you will likely prefer one of the previous generators over the A-iPower SUA12000E or its dual fuel version.

This is not due to the two extra decibels (although those could matter too) but because technical issues seem to be just a bit more common.

Pros

  • Noise levels of 78 dB
  • A-iPower SUA12000E offers 12000 starting watts, 9000 running watts, 50 amps, and 240 volts
  • Nice run time of 14 hours at 25% load
  • Weight of 206 lb (93.4 kg)
  • Has electric start
  • Four GFCI outlets
  • 2 years limited warranty
  • A lot of customers
  • Budget-friendly

Cons

  • A few cases of technical issues

Since many people use their 12000 watt generators for home backup power, suboptimal reliability definitely reduces the overall score.

The two years warranty, electric start, and four GFCI outlets of the A-iPower SUA12000E are welcome but not exceptional either.

It is true that this option tends to be slightly more budget-friendly than the quietest 12000 watt generators.

However, in the bigger picture, this price difference is typically not enough to make anyone consider the A-iPower SUA12000E over alternatives.
