5 Best 3500 Watt Inverter Generators in 2024

Looking for the quietest 3500 watts generators? Well, you have come to the right place. Welcome to my blog.

I review generators after using them personally or doing a lot of research on them. So, after researching and considering carefully, may I now present the 5 most Quietest 3500 watts generators!

A 3500-watt generator can run off multiple items, including small home appliances, power tools, and lights. You can also run a fridge, TV, microwave, computer, sump pump, and air conditioner with a 3500-watt generator.

I have picked these 5 out of the shinest candidates from the market after testing their sound level, runtime, and even ease of maneuver.

All these generators will act as a home backup and a portable power supply for your job sites. I also kept in mind the budget options and expensive options.

So that you can find a complete guideline while choosing the best generator for yourself.

In this list, all are inverter generators as silence is a key factor, the conventional generators failed to make the cut to this list.

5 Best 3500 Watt Inverter Generators

1. Generac 7682 IQ3500

Most Quietest
Generac 7682 IQ3500


  • 3,000 running watts – 3,500 starting watts
  • 212cc OHV 4-stroke engine
  • 120 Volts at 25 amps
  • Pull cord recoil start
  • Push-button electric start
  • 2.6-gallon fuel tank
  • 8.9 hour run time at 50% electrical load & 14.1 hours at 25% load
  • Quiet! Measured 55 decibels at 23 feet away
  • Parallel Capability (parallel kit sold separately)

The Generac IQ3500 is a strong competitor in the 35000 watts inverter generator category.

This generator comes with a few different operating modes – economy, standard, and turbo and these three modes let you adjust the power output to the connected load.

Having three modes in similar inverter generators is rare, so this feature is pretty eye-catching.

IQ 3500 has advanced inverter technology with a well-laid-out control panel and is pretty easy to operate. This inverter generator features two 20 amp 5-20R outlets, 2 USBs, 1 30 amp L5-30R outlet, and a 25 amp connection point for paralleling two Generac’s together for power outputs. So with a parallel kit, you can double the watts.

On gasoline, the Generac iQ3500 generator produces 3500 starting watts and 3000 operating watts. So now the biggest draw is Generac claims iq3500 is the quietest 3500-watt generator, even 40% quieter than Honda!

Let’s find out if it’s true. When I got my hands on this inverter generator I was quite skeptical as Generac is one of my favorite brands for a portable inverter generator. So the first time I pulled the generator I was like “Is it even working!?” At first, I thought there was something wrong with my generator and it was not running.

But when I realized the generator was running and it is so quiet my eyes nearly popped out of my head. I didn’t even have to engage it in eco mode, which by the way is an option you can use to ramp the engine down and it gets quieter. T

he noise level is 55 decibels. I can talk over the phone with this generator running right beside me. It’s really a super quiet generator! It is perfect for tailgate parties or campsites, or daily basis job sites.

Being an inverter generator you can get nice clean power out of it. The generator features another advanced technology which is Powerrush technology. It can provide the unit with 50% more starting power to start up the pieces of equipment. 

The EasyStart technology of Generac includes a pull start and easily located knobs on the side. You simply start up the generator also by pulling the recoil coil or pushing the electric start button.

It doesn’t take much effort which is pretty cool. The compact design of this generator makes it quite portable. But you will need a wheel kit to carry it around. It also has low fuel consumption. With a 2.6-gallon fuel tank, this inverter generator gave a very nice 6-hour run time with two refrigerators running on it.

Overall, I love this quiet inverter generator. My money is well spent. Can’t recommend this generator enough!
