Quietest 7500 watt generators performance on a score of 10 in important categories*

*Compared to similar generators and sometimes based on customer input

1. Powerhorse 7500i

The Powerhorse 7500i is the quietest 7500 watt generator with decibel ratings of 55 dBA to 63.9 dBA at 25% to 100% rated load.

If you don’t mind the higher investment required too much, the Powerhorse 7500i is often the best pick thanks to its quiet operation and solid quality.

In combination with the relatively long run time, the Powerhorse 7500i is a great generator for running things like an AC, refrigerator, and/or freezer overnight.

The low THD inverter power helps you avoid damaging any sensitive electronics too.

Pros

  • Quietest 7500 watt generator with noise levels of 55 dBA at 25% load to 63.9 dBA at rated load
  • Powerhorse 7500i offers 7500 starting watts, 6500 running watts, 50 amps, and 240 volts
  • Parallel capability
  • Good run time of 16 hours at 25% load
  • THD of 1.5%
  • Has electric start
  • Four GFCI outlets
  • 2 years limited residential and 90 days limited commercial warranties

Cons

  • Relatively short commercial warranty
  • Expensive for a 7500 watt generator
  • You may need some help moving the weight of 287 lb (130.2 kg)

Additionally, the four GFCI outlets help you avoid overloading the Powerhorse 7500i.

Food truck owners, event organizers, and other people in commercial situations do want to keep the 90 days limited commercial warranty in mind.

Additionally, you may need some help moving the heavy weight of 287 pounds (130.2 kg).

In short, the Powerhorse 7500i is not just the quietest 7500 watt generator but also a solid model in general.

If you really want to keep things quiet and have the budget, this option could be worth the investment.

2. A-iPower SUA7600iED

The A-iPower SUA7600iED is the quietest 7500 watt dual fuel generator thanks to its 63 dB rating.

To put this in perspective, a regular conversation is around 60 decibels.

A-iPower SUA7600iED

Noise levels aside, being able to run on both gasoline and propane can be helpful for certain situations and locations.

First of all, propane typically stores longer than gasoline. The A-iPower SUA7600iED allows you to be prepared for power outages or live off-grid in more convenient ways.

Secondly, if you only plan to use your quiet 7500 occasionally, propane tends to involve less maintenance.

Pros

  • Reasonable noise levels of 63 dBA
  • A-iPower SUA7600iED offers 7850 starting watts, 6100 running watts, 30 amps, and 240 volts
  • Parallel capability
  • Run time of 10 hours at 25% load
  • Less than 3% THD
  • In-depth performance tracking
  • Has electric start
  • Has a CO sensor
  • Weight of 130 lb (59 kg)
  • 3 years limited residential and 1 year limited commercial warranties

Cons

  • Not a lot of customer reviews yet
  • A-iPower does not always have the best generators
  • Pricey compared to other 7500 watt generators

One of the things you do want to keep in mind is that the A-iPower SUA7600iED is relatively new.

This is a downside because there is more uncertainty about the rate of technical issues. There are a decent amount of A-iPower generators that don’t do too well in this area.

In combination with the slightly higher price due to the inverter and dual fuel features, you may prefer one of the A-iPower SUA7600iED alternatives.

At the same time, this does look like a solid generator in terms of features.

There are not that many large and quiet dual fuel inverters like the A-iPower SUA7600iED either.

3. DuroMax XP7500X

At stronger generator power levels like 7500 peak watts, somewhat higher noise levels are more the rule than the exception.

The DuroMax XP7500X does alright with noise levels of 70 dB (typically measured at 25% load and 23 feet away).

However, this amount of decibels is already similar to a vacuum cleaner or freeway traffic.

And even if this noise is still acceptable to you, there are reasons why the DuroMax XP7500X and its dual fuel version are not on the list of the best 7500 watt generators.

Pros

  • DuroMax XP7500X offers 7500 starting watts, 6500 running watts, 30 amps, and 240 volts
  • Good run time of 18 hours at 25% load
  • Weight of 146 lb (66.2 kg)
  • Has electric start
  • Four GFCI outlets
  • 5 years limited residential and 1 year limited commercial warranties

Cons

  • Noise levels of 70 dB are already somewhat louder
  • High THD is not suited for running sensitive electronics
  • Reviews of the dual fuel version are not the most positive

First of all, the DuroMax XP7500X is not an inverter generator.

That means you need your own inverter or another way to clean up the power to run sensitive electronics like a TV, microwave, and many refrigerators safely.

Additionally, the suboptimal reviews of the dual fuel version imply that the reliability of the DuroMax XP7500X is not as great as certain alternatives.

In combination with the average price, you will likely prefer one of the other quietest 7500 watt generators.

4. Westinghouse wGen6000

At 72 dBA, the Westinghouse wGen6000 will not fit all definitions of quiet.

However, if you and your neighbors are okay with these noise levels, the Westinghouse wGen6000 is one of the best 7500 watt non-inverter generators.

Westinghouse wGen6000

It is worth noting again that you don’t want to run sensitive electronics off this generator without a way to clean up the power.

Additionally, there are a few cases where customers have issues with the electric start battery of the Westinghouse wGen6000.

Pros

  • Westinghouse WGen6000 offers 7500 starting watts, 6000 running watts, 30 amps, and 240 volts
  • Great run time of 13 hours at 50% load
  • Electric start
  • Four GFCI outlets
  • Weight of 183 lb (83 kg)
  • Relatively positive customer reviews
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • Noise levels of 72 dBA are already somewhat louder as some customers mention
  • THD of less than 23% is not suited for sensitive electronics
  • There are a few cases of issues with the electric start battery

On the flip side, the Westinghouse wGen6000 positively stands out in its great run time of 13 hours at 50% load.

This can be helpful for powering things through the night or through an event.

It also just allows you to enjoy your power for longer before having to refuel the Westinghouse wGen6000.

The electric start is not the most exceptional feature but it does make operating this “quiet” 7500 watt generator more convenient.

Another detail that really stands out is how budget-friendly the Westinghouse wGen6000 is. Even with all these quality features.

5. Champion 100592 7850

The noise levels of the Champion 100592 7850 may not be that impressive at 74 dBA.

However, in terms of overall quality, this is still one of the 7500 watt non-inverter dual fuel generators on the market.

Before going into detail about why this is, you may want to know about the Champion 201067 9000.

This alternative comes with a few decibels less and a nice amount of extra power.

Alternatives aside, the dual fuel feature of the Champion 100592 7850 adds the extra flexibility and convenience mentioned in the A-iPower SUA7600iED section.

Pros

  • Champion 100592 offers 7850 starting watts, 6250 running watts, 30 amps, and 240 volts
  • Dual fuel feature allows you to run on propane (LPG) too
  • Nice run time of 11 hours at 50% load
  • Has a CO sensor
  • Weight of 172 lb (78 kg)
  • Relatively positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers

Cons

  • Noise levels of 74 dBA are somewhat loud
  • High THD power is not suited for sensitive electronics
  • Relatively bad gasoline fuel efficiency

The 11 hours of run time at 50% load may not be as impressive as the Westinghouse wGen6000 but still really good.

This run time of the Champion 100592 7850 should be more than enough for running devices overnight, long DIY sessions, and similar purposes.

Additionally, the CO sensor adds a layer of safety. When the levels of carbon monoxide get too high around the generator, the machine turns off.

In combination with the relatively positive customer reviews and reasonable price, the Champion 100592 7850 can be the right choice for certain people and situations.

At least if the 74 dBA noise levels are not too loud.
