The quietest 3500 watt generators allow you to power nice amounts of appliances and tools while keeping the decibels down.

Quietest 3500 watt generators top picks

  1. Yamaha EF3000iSEB – Quietest 3500 watt generator (53 to 60 dBA) (25% to 100% load)
  2. Predator 3500 (56 dBA)
  3. WEN 56380i 3800 – Best quiet “3500 watt” generator (57 dBA) (3800 peak watts)
  4. Firman W03381 (58 dBA)
  5. Westinghouse WH3700iXLTc (58 dBA)
  6. Bonus mention: GENMAX GM3500iAED – Quietest dual fuel 3500 watt generator (62 dBA)

To make sure you have good quiet generators to choose from, I also included some models with slightly more than 3500 peak watts.

Additionally, keep in mind that 3500 watt generators with a few extra decibels could still be the right choice for your situation.

5 Quietest 3500 watt generators reviewed in-depth

As mentioned, while decibel levels are definitely relevant, you likely care about other details too.

The more in-depth reviews of the quiet 3500 watt generators below can help you make the right choice.

1. Yamaha EF3000iSEB – Quietest 3500 watt generator (53 to 60 dBA)

The Yamaha EF3000iSEB is the quietest 3500 watt generator with 53 dBA at 25% load and 60 dBA at 100% load.

In combination with the really long run time of 18.6 hours on a tank of gas, this generator can be great for powering something like an RV air conditioner overnight.

At the same time, you can definitely also rely on this quiet generator for things like backup power for a refrigerator with how few technical issues customers mention.

One thing you do need to know is that this 3500 watt inverter generator is very expensive compared to models of similar power levels.

Pros

  • Quietest 3500 watt generator with 53 to 60 dBA (25% to 100% load)
  • Yamaha EF3000iSEB offers 3500 starting watts, 2800 running watts, 29.17 amps, and 120 volts
  • Great run time of 18.6 hours at 25% load
  • Electric start
  • Clean THD power
  • CO sensor
  • Weight of 154.3 lb (70 kg)
  • Very positive customer reviews
  • 3 years limited warranty

Cons

  • Expensive compared to the other quietest 3500 watt generators
  • Bulky weight can be challenging to move around

Additionally, the relatively heavy weight of 154.3 pounds makes the Yamaha EF3000iSEB somewhat challenging to move around even with the wheels included.

That being said, as the positive customer reviews, the Yamaha EF3000iSEB can still be worth the investment for some individuals.

If you don’t mind investing more in a super quiet generator with impressive run times and reliability, this could be the right option for you.

2. Predator 3500 (56 dBA)

While it is not the number one quietest 3500 watt generator, you can still say the Predator 3500 deserves its “super quiet inverter” title.

On top of that, this option is also just a relatively solid generator with a reasonable price.

At the same time, you do want to know that the Predator 3500 does not have the best reputation in terms of durability and reliability.

Because of these things and the price difference, you will likely prefer the WEN 56380i 3800 which has a noise level rating of only one decibel more.

Pros

  • Relatively low noise levels of 56 dBA
  • Predator 3500 offers 3500 starting watts, 3000 running watts, 29.17 amps, and 120 volts
  • Parallel capability
  • Run time of 11 hours at 25% load
  • Clean THD power
  • Electric start
  • CO sensor
  • Weight of 102 lb (46.3 kg)
  • Relatively positive customer reviews
  • 2 years limited emissions control system and 90 days limited product warranties
  • A lot of customers

Cons

  • Short warranties
  • Generally not the most durable generator
  • Can be a bit challenging to move around

In case you don’t like the WEN generator brand, want to avoid all the decibels you can, and/or stumble upon really good deals, you could still consider the Predator 3500 too.

The run time of 11 hours at 25% load, electric start, and positivity of the customer reviews are not necessarily unique but nice at this price point.

So again, you will likely prefer the next quiet 3500 watt generator in terms of quality but the Predator 3500 is an option too.

Especially for things like RVs, camping, and running power tools where reliability tends to be just a bit less essential.

3. WEN 56380i 3800 – Best quiet “3500 watt” generator (57 dBA)

The WEN 56380i 3800 does not get the top spot of the best 3500 watt inverter generator because I give bonus points to models that actually have 3500 peak watts.

That being said, in terms of price and quality, you will likely prefer the WEN 56380i 3800 and its 3800 peak watts anyway.

WEN 56380i 3800

The 57 dBA are a few decibels louder than the previous options but with the knowledge that a conversation is about 60 dB, it should be clear the WEN 56380i 3800 is still super quiet.

On top of that, you get a good run time of 8.5 hours at 50% load and clean power with the THD of less than 1.2%.

Pros

  • Relatively low noise levels of 57 dBA
  • WEN 56380i offers 3800 starting watts, 3400 running watts, 30 amps, and 120 volts
  • Parallel capability
  • Good run time of 8.5 hours at 50% load
  • Less than 1.2% THD
  • Electric start
  • Weight of 99.2 lb (45 kg)
  • Relatively positive customer reviews
  • 2 years limited residential and 90 days limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • Relatively short commercial warranty
  • Rolling over uneven terrain can be challenging

One detail you do want to keep in mind is the 90 days commercial warranty.

Food truck owners and other people in commercial situations may be a bit hesitant about this.

Additionally, rolling the WEN 56380i 3800 over uneven terrain can be challenging with the small wheels. Carrying the 99.2 pounds is not that straightforward either.

These suboptimal points need to be mentioned but in the end, the WEN 56380i 3800 is still generally better than the Predator 3500 while being more budget-friendly too.

The Yamaha EF3000ISEB is still an option for some individuals too but many people will find the WEN 56380i 3800 worth the decibel price tradeoff.

4. Firman W03383 (58 dBA)

The Firman W03383 is a relatively quiet for a generator around the 3500 watt category and is still a good model but you will likely prefer one of the previous options.

This is mainly because there are a few cases where customers have technical issues with their Firman W03383.

Firman W03383

Additionally, the price tends to be a bit less competitive than other good 3500 watt inverter generators.

Pros

  • Relatively low noise levels of 58 dBA
  • Firman W03381 offers 3650 starting watts, 3300 running watts, 30 amps, and 120 volts
  • Parallel capability
  • Run time of 9 hours at 25% load
  • Has remote start
  • Less than 3% THD
  • Weight of 87 lb (39.5 kg)
  • Relatively positive customer reviews
  • 3 years limited warranty

Cons

  • A few cases of technical issues

The two main things that could change your mind are the remote start and any preferences for the Firman brand.

This remote start makes your camping, tailgating, and/or food truck experiences although you will still need to refuel the Firman W03381 more often than many other models.

In short, the Firman W03381 does deserve its spot in the list of the quietest 3500 watt generators and is still a good model but there are just better options available.

5. Westinghouse WH3700iXLTc (58 dBA)

The Westinghouse WH3700iXLTc does deserve a spot on the list of quietest 3500 watt generators with its 58 dBA but you likely don’t actually want to buy this model.

This is mainly because of how common technical issues are in this WH3700iXLTc which is somewhat uncommon for the Westinghouse generator brand.

Westinghouse WH3700iXLTc

Additionally, the 8 hours of run time at 25% load is below average too.

If you plan to run something like an RV air conditioner overnight, the Westinghouse WH3700iXLTc may be quiet enough but you only get half a night (or less) of actual cooling.

Pros

  • Relatively low noise levels of 58 dBA
  • Westinghouse WH3700iXLTc offers 3700 starting watts, 3000 running watts, 30 amps, and 120 volts
  • Parallel capability
  • Less than 3% THD
  • Weight of 70.5 lb (32 kg)
  • 3 years limited residential and 1 year limited commercial warranties
  • Budget-friendly

Cons

  • Run time of 8 hours at 25% load is below average for 3500 watt generators
  • Good amount of reviews with technical issues

One positive point that is worth mentioning is the light weight of 70.5 pounds (32 kg).

Compared to the other quiet 3500 watt generators, it will be relatively easy to carry the Westinghouse WH3700iXLTc around.

So again, even with the budget-friendly price and solid warranties, you likely don’t want to go for the Westinghouse WH3700iXLTc.

There are higher-quality and quieter 3500 watt generators and the WEN 56380i 3800 even tends to be more budget-friendly.
