Research and luck brought me to Wen 56125i – a lightweight and compact inverter generator – emphasizing with miniscule fluctuations. These are well-known for voltage fluctuation prevention by mimicking natural sine waves.

At full capacity, it generates to limiting harmonic distortions to 1.2%, creating 100% “clean energy” to smoothly run sensitive electronics like smartphone, small TVs, and laptop.

In worst cases, the “Overload Protector” circuit breaker will work its way to keep your devices from damage.

Wen 56125i also releases 51 decibels of noise level from the distance of 22 feet – making it as super silent as a window air conditioner sound. Whether it’s for home use or campsite, nobody would feel disturbed at all.

During a long road in an RV, I understand that some people need more juice. And the parallel compatibility built in this generator can help you pair with another Wen to double the runtime.

But take note that, a Wen 56125i connector kit and some assembly might be required.

Overall, I find this generator is the most compact and versatile option that won’t break your bank.

The Champion 3400-watt inverter generator is built with lots of easy-to-use components. From the attached handle, sturdy wheels to the low-oil auto-shutoff feature.

While 70% generators out there is started by a recoil starter with a pull cable, this highlights the extra electric start option that makes everything easier and more convenient.

What I love the most is its fully RV-ready construction. With the parallel-ready capability, attached wheels, two easy-to-transport handles, one special 50A RV outlet, and 192cc Champion engine that can run any 15,000 BTU AC, what else to ask?

Contrast to such powerful performance, its noise level is just 59 decibels. But it will be quieter if you use Economy Mode and run it a quarter-load.

Take note that the noise level will fluctuate a little bit based on different loads. The higher the load, the louder the generator. But in this case, it’s quite acceptable, at least in my standard, to perfectly a good choice for camping or tailgating.

Generally, this is a good choice for those who are finding for a powerful inverter generator but still want it to be silent.

Contrast to its powerful construction, the generator is rather silent. It is cased carefully to reduce noise down to 62 decibels. From 23 feet, it’s hard to be heard.

If reliable power on-the-go and air pollution are your concerns when considering a generator, the USA-engineered Westinghouse iGen4200 should be in your wish list.

How to choose the quietest inverter generator (buying guide)

Quietest Inverter Generators for Home & RV Use

Noise Level

Not many people know that even inverter generators provide a wide range of noise levels which they’re going to work with. Some of them go within 48 – 51 decibels while others work as higher as 57 – 65 decibels.

And, the definition of “silence” is quite more about a preference issue. You need to find the comfortable noise range of your generator as well as where it’s going to be applied.

I mean if it’s a generator for campgrounds, it should be silent enough for the nights while for home use, choosing a less noisy but powerful enough product is a must. Or, for RVs and job sites, muff moderate noises are allowed.

Find the noise ratings on the body of the generator or on its package.

Power Output

Power output is dependable on how much power you’re going to need as well as your budget. Why does it have the “budget” element here? It’s because of two major consequences when opting for a more powerful generator:

  • The higher price it costs
  • The more fuel it requires

Normally, a 1250-watt inverter generator is enough for people to operate their small lights, fans, TVs, electric razors, and gaming consoles. The higher power consuming devices, the more power output required on your generator.

For example, a 2000-watt model is a nice choice for coffee machines, electric ovens, BBQ grills, and normal equipment. Level up, a 3000-watt generator and up can handle anything you’ve got, which is why it’s the most favorite for campgrounds, tailgates, or RVs.

No doubt, they are mammoths!

Runtime, Fuel Tank, & Fuel Efficiency

These three elements get a close connection with each other.

The longer you need a generator, the higher runtime it should be. Consider:

  • How constant of power outages happened around your living area
  • How frequent of your camping trips
  • How long you spend on the road in your RV?

Then, figure out the suitable runtime range and go for the product(s) that can provide you continuous power supply such that amount of time.

The longer the potential runtime, the more fuel you need than normal. That’s why a bigger fuel tank is highly recommended in this case.

In case there are too many electric appliances or gears to manage while the runtime of your generator can’t afford for that, my advice is joining two products (of the same brand) together.

In this case, a connector kit is great for that task while the runtime is ensured now.

Another way to optimize and maximize the runtime of a generator is to make it fuel efficient! This handy ability is only in inverter generators that help to adjust their engine speed based on how much electronic gear they’re providing power to.

And this function is carried out via microprocessors. But for optimal performance, they should be checked in “economy mode”.


To me, a good quiet inverter generator should also be portable, no matter it’s heavy or lightweight.

By attaching some handles at their back or wheels at their feet, it makes the transporting easier and more effortless from A to B.

Who makes the quietest inverter generators?

Quietest Inverter Generators for Home & RV Use

Or should I say: Which brands produce the quietest inverter generators? Well, based on my experience, there are 5 must-try:


In the generator game, Wen (with its long history) is like a king. Their inverter generators have got high appreciation from worldwide fans for the powerful engine, comfortable noise level, and affordable price.


Founded in 1887, this Japanese company has gained a good reputation up to now due to its wide range of inverter generators. They cater to various budget ranges and needs, from 1000 watts to 12,000 watts to perfectly suit your home use or great outdoor occasions.

Briggs & Stratton

Their 3-year warranty always makes their customers feel secure while their inverter generators nail up with silence and fuel efficiency performance. One thing for sure, their products never break your bank.


This international company gets fame for its versatile inverter generators by providing a wide range of designs. From home use to RVs, from campgrounds to tailgates, they are on point. And as always, very silent!


If Wen is the king, Westinghouse is the queen in this industry. The 100-year brand never disappoints its customers about its products’ value and quality. For the most powerful inverter generators on the market, you should pick this.


Quietest Inverter Generators for Home & RV Use

What is difference between inverter generator and regular generator?

The biggest difference and also the distinctive feature making inverter generators more convenient than its siblings is they can dish out DC and AC current while others can’t.

In fact, those traditional models, like the conventional generators just provide AC current. So, they’re not safe for sensitive electronics like smartphone, TVs, or tablets.

Are inverter generators better?

Yes, they are. Compared to traditional generators, inverter generators are superior in:

  • Easier transporting (due to their attached wheels and handles)
  • More compact silhouette
  • Lower noise level
  • More fuel efficient

How many dB is a quiet generator?

In general, the quietest inverter generator should be measured under 65 decibels.

But the its acceptable quietness will be based on each environment and application in which it is used.

For example, a 64-decibel generator is considered silent for RVs and tailgates but a no-no for campgrounds since it turns out to be noisy during the nights.

Based on my experience, a generator for home & RV use should ideally be 52-62 dBA because it will ensure two things: Power output and acceptable silence.

How many kW generator do I need to run a house?

To determine what size of a must-have generator for your house, here are my easy 3-step instruction:

Step 1: List out the appliances and fixtures you want to power

Step 2:  Find on their appliance label to figure out the approximate starting and running wattage of each in your list. If it doesn’t show these numbers, this is a good preference.

Step 3: Sum up the wattage. Then, find a generator that’s powerful enough to exceed that amount.

For example, if your list includes these appliances:

ApplianceStarting/Running Wattage
Incandescent Lights (6 units)360/360 (60W x 6)
Window Air Conditioner (10,000 BTU)2200/1500
Total Wattage3810/2042

In this case, you need at least a 4000W generator, because the combined starting wattage is 3810W.

How much can I run on a 2000 watt generator?

A 2000-watt generator is perfect for big house appliances such as coffee machines, BBQ grills, and electric ovens. Obviously, other smaller equipment is allowed as well.

How long can you run an inverter generator continuously?

It depends on the runtime indicated on the product’s package or body. But the recommended runtime should be at least 5 hours.

Is it safe to leave a generator unattended?

No, it isn’t.

Never leaving a generator (which is running) unattended. You’d better turn it off when away from home or at night.

Should a portable generator be grounded?

Again, it’s a dependable thing that you need to check out its manual to know whether the machine is required grounding or not.

My experience is if the generator is a separately derived system, a grounding rod is highly recommended and vice versa.


There it is. I hope that this ultimate buying guide has helped you figure out the quietest inverter generators. And remember, after copping it home, take good care of your generator to encourage its performance to the best.

Sharing is caring. If this article is helpful for you, it might be with your friends, share it!
