Quietest 1000 watt generators top picks

  1. Honda EU1000i – Quietest 1000 watt generator (42 to 50 dBA at 25% to 100% load)
  2. WEN 56125i – Budget-friendly (51 dBA)

  5. GENMAX GM1200i (58 dBA)

Decibel ratings definitely matter but keep in mind that there are other relevant features too.

That means a 1000 watt inverter generator that is lower on the list could still be the best option for your situation.

How we selected our top picks

Decibel ratings and customer reviews about noise levels are the main things that influence the ranking of the quietest 1000 watt generators above.

5 Quietest 1000 watt generators reviewed in detail

As mentioned, you likely also care about other details besides decibel ratings.

You can get an idea of what quiet 1000 watt generator is the best for your personal situation with the detailed reviews below.

1. Honda EU1000i – Quietest 1000 watt generator (42 to 50 dBA)

The Honda EU1000i is the quietest 1000 watt generator and likely just the quietest generator on the market with 42 to 50 dBA at 25% to 100% load.

Besides offering silent operation, this ultra quiet generator from Honda also has a good reputation in terms of reliability and durability.

Honda EU1000i

The CO minder which can help you avoid carbon monoxide levels that are too high also positively stands out.

One thing you do want to keep in mind is that the Honda EU1000i is relatively pricey compared to other quiet 1000 wat generators.

Pros

  • Quietest 1000 watt generator with 42 to 50 dBA at 25% to 100% load
  • Honda EU1000i offers 1000 starting watts, 900 running watts, 8.3 amps, and 120 volts
  • Parallel capability
  • Run time of 6.8 hours at 25% load
  • Less than 3% THD
  • Light weight of 28.7 lb (13 kg)
  • CO minder
  • Relatively positive customer reviews
  • 3 years limited residential and 12 months limited commercial warranties

Cons

  • Pricey compared to other quiet 1000 watt generators
  • Fuel efficiency is not that good

Since this power level is often not enough as home backup power for appliances, there will be many people that don’t find this worth the extra investment.

Additionally, the fuel efficiency of the Honda EU1000i is not that good which means it gets relatively small amounts of kWh out of a gallon of fuel.

Whether the Honda EU1000i is worth the investment for you ultimately depends on details like your budget, how quiet you want your 1000 generator to be, and how many hours you plan to use the machine.

In simple words, you can see this as more of a luxury generator where you invest a bit more for really silent operation and good durability.

2. WEN 56125i – Budget-friendly (51 dBA)

The 51 dBA of the WEN 56125i may sound like and is a big jump over the Honda EU1000i but you do want to keep in mind that a regular conversation is still around 60 decibels.

In simpler words, the WEN 56125i and the other “1000 watt” generators on the list are still relatively quiet.

WEN 56125i

That being said, there are other reasons why you likely want to pass on the WEN 56125i unless you are on a really tight budget.

The first reason is that this generator does not have that many customers yet.

Pros

  • Low noise levels of 51 dBA
  • WEN 56125i offers 1250 starting watts, 1000 running watts, 10.4 amps, and 120 volts
  • Parallel capability
  • Nice run time of 5 hours at 50% load
  • Less than 1.2% THD
  • Light weight of 31.6 lb (14.3 kg)
  • 2 years limited residential and 90 days limited commercial warranties
  • Budget-friendly

Cons

  • Relatively short commercial warranty
  • A few cases of technical issues
  • Not that many customers yet

This is relevant because even models from reputable brands are sometimes not ideal. Customer reviews tend to uncover these.

For now, the reviews of the WEN 56125i do not look that great with a decent number of technical issues.

You still have the warranties to fall back on and WEN generators do tend to be good but these details could be enough to consider other options.

Even with how budget-friendly the WEN 56125i is.

3. Westinghouse iGen1500c – Best quiet 1000 watt generator (52 dBA)

While the Westinghouse iGen1500c is not as quiet as the previous 1000 watt generators, many people will find it the best option for their preferences and needs anyway.

This is because of the solid features, reasonable price, and brand reputation of the Westinghouse iGen1500c.

Westinghouse iGen1500c

It is important to mention that the Westinghouse iGen1500c specifically does not have that many customer reviews yet.

In theory, this could still be a 1000 watt generator with issues that are not visible from a list of features.

Pros

  • Low noise levels of 52 dBA
  • Westinghouse iGen1500c offers 1500 starting watts, 1000 running watts, 12.5 amps, and 120 volts
  • Parallel capability
  • Good run time of 12 hours at 25% load
  • Less than 3% THD
  • Light weight of 20 lb (9.1 kg)
  • CO sensor
  • 3 years limited residential and 1 year limited commercial warranties

Cons

  • Not that many customers for this specific model yet

That being said, with all the quality generators the Westinghouse brand offers and the similar design, this would be very surprising.

Additionally, the Westinghouse iGen1500c has three years limited residential and one year limited commercial warranties to rely on.

Compared to the other options on this list of quietest 1000 watt generators, the Westinghouse iGen1500c has a lot of starting watts.

This can be helpful if you plan to power something like an energy-friendly refrigerator or freezer that needs an extra burst of power to get going.

In short, while more customer reviews would be welcome, the Westinghouse iGen1500c is likely still the best option for you.

4. Sportsman GEN1000i (56 dBA)

The Sportsman GEN1000i is another example of a 1000 watt generator that does deserve its spot on the list of quietest models but does not actually look that great.

A lot more so than the WEN 56125i which is more promising in terms of quality and duration.

The first reason for this is that the Sportsman GEN1000i reviews I could find had a decent number of cases with technical issues.

Pros

  • Relatively low noise levels of 56 dBA
  • Sportsman GEN1000i offers 1000 starting watts, 800 running watts, 8.3 amps, and 120 volts
  • Nice run time of 6.3 hours at 50% load
  • Clean THD
  • Light weight of 20.7 lb (9.4 kg)
  • 1 year limited residential and 30 days limited commercial warranties

Cons

  • Short warranties
  • Seems to be only available in refurbished versions
  • Not the best generator brand reputation

Secondly, it is fair to say that Sportsman generators do not have the best brand reputation in terms of quality.

Add to these things the short warranties and that the Sportsman GEN1000i only seems to be available in refurbished models and you likely don’t want to go for this generator.

Especially not with quieter, higher-quality, and similar-priced 1000 watt generators like the Westinghouse iGen1500c available.

5. GENMAX GM1200i (58 dBA)

Even this low on the list, the GENMAX GM1200i is still relatively quiet with a decibel rating of 58 dBA (at 25% load and 23 feet away) which is fewer decibels than a regular conversation.

At the same time, it is not just the slightly higher number of decibels that makes this GENMAX GM1200i less attractive than other quiet 1000 watt generators.

GENMAX GM1200i

This is another option where there are a decent number of technical issues in the customer reviews.

Additionally, GENMAX has a very average reputation when it comes to quality and customer support. Even when you are still within the short one year warranty.

Pros

  • Relatively low noise levels of 58 dBA
  • GENMAX GM1200i offers 1200 starting watts, 1000 running watts, 10 amps, and 120 volts
  • Parallel capability
  • Run time of 6.8 hours at 25% load
  • Less than 3% THD
  • Light weight of 25.3 lb (11.5 kg)
  • CO minder
  • 1 year limited warranty
  • A lot of customers

Cons

  • Relatively short warranty
  • Fuel efficiency is not that good
  • Decent number of technical issues

The two things that positively stands out in the GENMAX GM1200i are the CO minder and many customers but even these details are not completely unique.

On top of these things, the fuel efficiency and run time are somewhat below average too.

In short, the GENMAX GM1200i is not just low on the list of quietest 1000 watt generators. It is below average in many other areas too.

That means you will very likely prefer one of the previous generators.

Honda EU1000i
