Quietest 4000 Watt Generators 2021: Reviews
1. Pulsar 4000W Portable Quiet Inverter Generator
How convenient! We recommend the Pulsar Inverter Generator due to its many useful features.
It does not only produce relatively less noise but is also the perfect choice for you if you are looking for a portable generator with easy installation.
To begin, we’d like to state that this generator lasts up to 15 hours on 3.4 gallons of fuel. Even at half load, that sort of run time is not something many products can boast about.
We did a full analysis and got to the result that the claim is true and there is a generator that has a running power of 3500W and full power of 4000W.
Its compact design made it portable and easy to handle which is one of the greatest features of this generator. We took this product outdoors and switched it on/off from a max distance of 70 ft. Surprisingly, it worked every time.
Thanks to the Stable sine WAVE mechanism, you’re also guaranteed safe electrical power for charging even sensitive devices such as cell phones and laptops.
- Low noise level
- Great design that maximizes portability
- Remote-controlled operation
- Available for almost 15 hours even on half load
- Need for improvement in customer service and after-sale service.
2. Westinghouse iGen Super Quiet Inverter Generator
It has almost similar features as the first generator in our list.
Especially because it is extremely quiet and portable that makes it one of the best choices.
According to our research, it is as good as a Pulsar generator if not better than that.
Although costlier than our first pick, the Westinghouse generator carries enough features to justify the extra dollars. So it’s definitely worth it if you can afford it.
The first big feature being 18-hours runtime (in comparison to 15) with just 3.4 gallons of gasoline.
That is impressive, considering it runs at 3700W and peaks at 4500W, making the model safe for a broad range of appliances.
Other notable features of this generator that make it unique include it’s LED Data Center, which displays Fuel level, Remaining runtime, and power output. Not to forget the advanced portability made possible by a telescoping handle and convenient top carrying handles.
In case you’re curious about the noise level, let us put your worries to rest and say that it is quieter than the Pulsar. Producing sound as low as 52db, this model is a great choice regardless of where you want to use it.
- Impressive power and portability
- Produces only 52 DB sound, which is very low
- Works efficiently for 15 hours even of half load
- Customer service is mediocre
3. Champion 4000-Watt RV Ready Open Frame Inverter Generator
This generator is a great product of the Champion brand that is also known for tailgating and RV’s.
As compared to other 4000W models they are known to be 20% more light and 50% quieter. Through our research, we’ve found out that it is one of the best.
This item makes bold promises, sure, but it doesn’t live up to only a few of them. For instance, we didn’t find the product to be 50% quieter compared to similar generators.
But that’s not to say it is loud; it produces a max of 64 dBA sound and that is tolerable. What we liked is the fact that it also runs for an average of 15-17 hours.
The company claims that it has an Economy mode that makes it fuel-efficient and saves fuel consumption, giving you a cut in your expenses.
We do not guarantee this feature but we do not have anything to claim otherwise too. Individuals have tried experimenting by connecting another 2800W inverter with and it worked just fine you can use an inverter with higher power too.
- Light, portable, and easy to use
- You can connect other inverters
- It is completely secure for all the appliances at home.
- Noise can be higher than 64 dBA
4. DuroStar DS4000S Generator
The DuroStar DS4000S, for instance, carries many important factors from the previous models such as greater portability, multiple outlets, low-noise rating, etc.
Well, this generator is a worthy purchase because it brings quite a lot of features from more expensive models like the Pulsar 4000 and Westinghouse.
To start, we must applaud the efficiency of this model as we can power everything, from sensitive items like phones and laptops to high-performance power tools.
Like others, this one also runs at 3300W and peaks at 4000W; it has an 8-hour runtime at half load and burns through 3.96 gallons of gas.
While these aren’t figures to be ecstatic about, the product makes up for it by weight, as it measures only 94lbs. We also liked how the steel frame has four-point isolated motors to keep the noise low.
- Quiet operation
- Good portability factor
- Doesn’t cost too much
- Powers a broad range of appliances
- The runtime could’ve been a bit more
5. WEN 56475 Portable Generator With Electric Start
It is a sturdy machine that’s high in portability, extra thanks to the wheel kit, and comes with an electric start for added convenience.
Since portability is a big selling point here, we decided to take this model of a camping trip to test it out.
There is no special fault in these generators that we must mention and we can only guess based on other people’s reviews who have already used this product and have experience.
The most common complaint the users made was problems with easy turning on of the generator or sometimes sudden turnoff. In case of any troubles, you can count on their warranty policy and other terms and conditions.
Like mentioned before, this model comes with an electric start, which is great because the last thing you’d want to do outdoors is use pull starts.
This great keyless generator can get all your appliances like refrigerator, light, and TV running with just a push of a button. We tried the generator at home too, so we can vouch for it.
With a 4-gallon gas tank and 223cc engine, this machine can last up to 11 hours at half load. It is quite impressive performance as compared to the previous model we mentioned.
Its unique features and perfect performance is what makes it a great choice! Other interesting features are low-oil shutdown, overload protection, and auto-voltage regulator.
- Electric start button
- Powers a host of appliances safely
- 11 hours run time
- Availing the warranty could be a problem
Is It Possible to Make A Quiet 4K Generator Virtually Silent?
Adjust the Pipe Positioning
The loud noise of the generator can be due to a common reason of horizontal pipes. Horizontal pipes are the cause because due to this position the sound waves travel directly in the direction of some object.
Usually, the instruction manual of the generator instructs you to face the exhaust of the generator away from your house or rest of the buildings but there is a chance that your neighbors at home of campsite complain about that.
To solve this problem face the exhaust pipes upwards. A more vertical direction ensures that it is not facing any object directly. Hence reduces noise.
You get mufflers in the package of generators usually but if you feel that they are not working properly then you can ask the company for the replacement by contacting their service providers or you can contact the nearest hardware store to ask for the best mufflers for your generator.
Water Bucket Trick
You don’t need to adjust permanently in this method rather you make changes in its functioning. As water is a sound insulator, the noise from the machine is directed towards a bucket of water to reduce noise.
To make this work, connect a hose to the exhaust and have the other end drop into a bucket filled with water. You can change the position of the generator to a higher place to avoid entry of water into the exhaust pipes.
You can also do so by punching a hole in the bucket where the hose reaches the top.
However, this method cannot dampen the noise production by vibration but it is quite effective to reduce noise from exhaust pipes.
