Generators can provide emergency electricity in the event of a blackout, run power tools on the job site, and deliver affordable energy for necessities when you’re camping or RVing.

The quietest generators are usually inverter generators which have a computer-controlled inverter, are compact, have small, efficient motors, advanced mufflers, and great fuel-efficiency. While a traditional generator runs at the same speed, an inverter generator self-regulates and the power delivery is more consistent.

It can be difficult to pick the best quiet generator to have on standby. The following recommendations will help clarify their capabilities, so you can be confident in making the right choice.

What to Consider When Choosing the Best Quiet Generator

A variety of important factors go into selecting the best quiet generator for your backup power needs. The info below will help narrow down a unit that provides enough power, portability, and operates at a low decibel.

Power Output

Wattage should be the most critical factor as you shop. Generators come in different wattage ratings and the higher the wattage rating, the higher the power output. Higher wattages usually mean larger, more expensive units, but quiet generators are usually compact and small, providing moderate power output for laptops, smartphones, and other small devices.

Those in the 1,000- to 1,600- watt range are great for camping and job site use, but not for home backup. For that you need a minimum 2,000 watts (which will run an oven or large refrigerator) although you’ll want 3,000 watts or more to run several items concurrently. Every electrical device has a label with the watts rating on it which may help when deciding which generator to buy.

Fuel Type & Capacity

Quiet inverter generators typically use gasoline as a fuel source, and dual fuel generators can run on propane as well. This is a big advantage, as it allows you to choose the fuel you use based on your needs, such as power output requirements, fuel availability in your area, and the fuel type that you have on hand.

Inverter generators have an isolated gasoline tank with a fuel capacity that ranges from as small as 2 gallons to more than 10 gallons. The larger the fuel tank is on the generator, the longer it will be able to provide gasoline-based power, but the size of the generator itself also increases.

Fuel capacity has no bearing on how much propane you can use with the generator; propane gas is stored under pressure in canisters, which attach to the generator with a hose and pressure regulator for direct fuel consumption.

Noise Level

Quiet inverter generators are roughly half as noisy compared to large or open-framed models, often in the 50 to 60 dB range. To better understand generator noise output, consider these common sounds and their equivalent operating dB level:

  • Refrigerator: 50 dB
  • Normal conversation: 60dB
  • Hairdryer: 70 to 90 dB

The quietest generators also use sensors to detect how much power they need to expend, throttling down for smaller loads and producing lower noise levels. Your neighbors, either at home or a campground, will appreciate that you purchased a quiet inverter generator over a noisy, open-framed model.

Size and Weight

Physical size and weight will also be a factor for some shoppers to consider. Since these units are meant to provide power where you need it, small inverter generators are usually top-handled or side-handled units that can be picked up with one hand and carried with ease, as they’re typically lightweight at about 40 to 50 pounds.

Heavier units weighing up to 100 pounds come with wheel kits to make portability easier. Both constructions are compact enough to bring to the campsite, stow in the car, or keep in the garage when you need the backup power.

Additional Features 

The quietest portable generators can be equipped with features that make their operation as convenient as possible. These include:

  • Electric Start: Instead of using a pull-cord to manually start a generator, many modern generators offer an effortless electric start. This mechanism can be in the form of a push-button, a switch, and even an electric start operated by remote control. Automatic transfer switches also fall into this category.
  • Multiple Outlets: Not only are multiple outlets convenient, but they also help distribute the generator’s electrical load when powering multiple devices. Having a quiet generator with at least two household electrical outlets is recommended for efficiently spreading the electrical load. Quiet generators may also have RV outlets and USB outlets.
  • Line sharing: Purchasing a set of like-branded generators will often give you the ability to wire them in parallel, also known as load sharing. This means that by using a brand-specific kit, you can plug one generator into another to combine their wattages and produce even more power. Load sharing can also be a less expensive way to produce enough wattage to run large appliances or power everything in an RV at once.

Our Top Picks

The following products, selected according to the shopping considerations above, represent some of the best quiet generators on the market. Whatever your needs may be, there’s likely to be a generator on this list that’ll hit the mark.

Best Overall

Generators have two ratings: one for startup watts (most electrical devices produce an initial surge) and one for running watts. The latter is usually significantly lower—a drop of as much as 25 percent in real-world performance—but the efficiency of the Honda unit is underlined by a mere 10 percent difference. That makes the EU3000iS with its 2800 running wattage equally useful at home or on the go.

It runs at between 49 and 58 decibels, which is quiet enough for campsite use. You’ll get anywhere from seven hours to as much as 20 hours on one 3.4-gallon tank of gas. Though this model doesn’t score well with fuel consumption, starting is easy, and the motor has both overload protection and low oil alert. There’s no dedicated USB port, but you can always run the required charger off one of the 120V household sockets.

Product Specs 

  • Noise level: 49-58 decibels
  • Wattage: 2,800 watts

FAQs

Looking for more information about the quietest portable generators available? Consider the answers to some of the most frequently asked questions about this particular type of generator.

Q: What is considered quiet for a generator?

Since many generators on the market operate at loud volumes, a generator can qualify as a quiet option if it runs at under 60 dB.

Q: Why are inverter generators so quiet?

Inverter generators don’t use alternators, like typical open-framed models might and which require the engine to work harder and produce more heat. For that reason, inverter generator engines run more quietly. In addition, manufacturers can close them inside plastic housing for even better noise control without overheating.

Q: Do generators have to be maintained?

Just like your car, a generator’s engine requires periodic maintenance. This includes routine oil changes (after 20 hours of use for a brand-new generator and every 100 hours of use afterward), cleaning the air filter after 100 hours of operation, and ensuring that you run it for 20 or 30 minutes at least once every three months.

Q: Can I leave my generator running overnight?

It isn’t recommended to run a generator continuously. Models that rely on gas should not run after their standard runtime which can be determined by their weight, tank size, and power consumption.
