How We Chose the Best Quiet Generators

The quietest portable generators keep electronic devices charged, RV AC units cool, and small appliances running without making too much noise. While sleeping at a campsite or when in earshot of residential areas, quiet generators typically have 49- to 61-decibel volume levels.

Many quiet portable generators have sufficient wattage to power devices, ranging from 1,000 to 3,000 watts. Select models are powered by gasoline only, while others also offer dual-fuel capabilities. Parallel connection is also available in a few generators, though kits or cords are usually sold separately. Convenience is also prioritized with carbon monoxide detectors, easy-to-use electric starts, built-in handles, or LED and LCD screens for monitoring.

Since many of these models are inverter generators, portability is also an important factor. Most are lightweight and have compact designs, while others may be too heavy for some to carry. Finally, each of the quiet generators on our list comes with a variety of outlets, including household outlets, USB ports, RV outlets, or even DC outlets.

Best Overall

The Best Quiet Generator Option: Honda EU3000iS Gas-Powered Portable Inverter

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 quiet generator is underlined by a mere 10 percent difference. That makes the EU3000iS with its 2,800 running wattage equally useful at home or on the go.

Regarding noise, it runs between 50 and 57 decibels. At low power, it’s as close to a noiseless generator as we found, and certainly quiet enough for campsite use. Owners can expect 19.6 hours of runtime on one 3.4-gallon tank of gas. Though this model doesn’t score well with fuel consumption, starting it is easy, and the motor has both overload protection and a low-oil alert. There’s no dedicated USB port, but owners can always run the required charger off one of the 120-volt (v) household outlets.

What to Consider When Choosing a Quiet Generator

There are a variety of factors to consider ahead of buying a quiet generator for backup power needs. In this section, we take a closer look at what these factors are to help shoppers find a model that provides enough power and portability at the lowest decibel levels.

Power Output

Wattage is typically the most critical factor to consider when buying a quiet generator. While generators typically have different wattage ratings, here’s an important point to remember: 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 minor jobsite use, but not for home backup. For that, a minimum of 2,000 watts is recommended (to run an oven or large refrigerator), although 3,000 watts or more will be needed 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 and Capacity

Quiet inverter generators typically use gasoline as a fuel source, and dual-fuel generators can run on propane, too. This is a big advantage, allowing owners to choose the fuel they use based on their needs, such as power output requirements, fuel availability in the area, and the fuel type that they 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 generator fuel tank, 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 can be used 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 usually half as noisy as large or open-framed models, often in the 50- to 60-decibel range. To better understand generator noise output, here are some common comparable sounds:

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

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. Neighbors, either at home or a campground, will appreciate that a quiet inverter generator was chosen over a noisy, open-framed model.

Size and Weight

Physical size and weight will also be factors for some shoppers to consider. Since these units are meant to provide power where it is needed, 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 around 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 for when backup power is needed.

Additional Features 

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

  • Electric start: Instead of using a pull cord to start a generator manually, 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.
  • Load sharing: Purchasing a set of like-branded generators will often provide the ability to wire them in parallel, also known as load sharing. This means that by using a brand-specific kit, owners 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.


Here are some of the most frequently asked questions we get from shoppers who are looking for the best quiet generator for their homes.

Q. What is considered quiet for a generator?

A range of 50 to 60 decibels is considered quiet for a generator. Unlike many traditional generators, which operate at loud volumes, modern inverter models are much quieter. While there is no such thing as a portable silent generator, any that run at under 60 decibels (about the same level as normal conversation) are generally defined as quiet. Some manufacturers suggest a higher limit of 75 decibels, which is similar to office noise or high-quality vacuum cleaners.

Q. Why are inverter generators so quiet?

Inverter generators don’t use alternators like typical open-framed models might, requiring 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 it runs for 20 or 30 minutes at least once every 3 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. Overnight needs can often be supplied by a portable power station that can be recharged using a quiet generator or by using an environmentally friendly solar generator.
