A small quiet generator is a device so useful, it would be a great addition to every home. Regardless of whether you are an avid camper or live in the area where power outages are common, this item would be a wise investment. At the very least, it would ensure you have some measure of energy in case of an emergency, which is sure to put your mind at ease. The only issues is that there are so many of these devices on the market today that buying the best portable generator becomes a challenge.
This guide would help you understand the important features of these power tools and determine which would suit your particular needs best. Remember that your personal energy requirements must be the most important consideration when shopping for this kind of item.
What to Look for in the Best Portable Generator
A good quiet portable generator must be convenient to use and fuel-efficient. The former means that it should be easy to transport whenever you need and quiet enough to ensure your comfort. Most of these devices operate at under 60 dB, so that’s what you should expect from the best portable generator. However, some models are that quiet only when working on a half or even quarter load. As this is the number listed in most ads, be sure to read the product specifications thoroughly so that you know how noisy the tool truly is when running at full power.
Depending on your personal preferences, you may look for some special features, such as low emissions or a solar power charge. The designs of super-quiet generators vary greatly, and some of them are even stylish enough to be displayed at parties. If portability is an important consideration for you, look for a model with a good handle.
One feature that the truly best portable generator must have is the Clean Energy technology. This is the tech that allows plugging sensitive microcomputers (laptops, smartphones, tablets, etc.) directly into the device. Without it, the delicate electronics can be damaged by power surges. A non0clean energy generator can be used to power these gadgets as well, but it will require an additional inverter that would stabilize the power output.

What Makes a Generator Portable?
An electrical generator is a device transforming some kind of energy into electricity. The equipment that supplies power to the cities are extremely big and, of course, stationary. In order to make this kind of tool portable, one must supply it with an engine. Note that some types of engine generators are stationary as they are large and can produce over a million Watts of electricity. The vast majority of privately owned portable generators are much smaller, and the quietest models among them are tiny, some weighing under 30 lbs.
There is a direct correlation between the size and type of the engine and the level of noise a generator produces. Therefore, if you need the best portable generator power-wise, you would have to accept that it would be heard quite well. Luckily, the inverter technology used in the majority of super-quiet generators, allows minimizing the noise by reducing the RPM. A device like this can offer the output of up to 2000 Watts, which is sufficient for the majority of personal-use needs.
The inverter is the key to Clean Energy technology that makes generators safe to use with sensitive electronic devices, like computers and tablets. The reduced RPM rate allows for a more stable power output, which means that microcomputers will be protected against sudden power surges.
Aside from the engine and inverter, a small portable generator usually consists of a fuel supply, voltage regulator, engine speed regulator, and a lubrication system. Cooling and exhaust systems also are essential parts of this device as no motor can work efficiently without them. The best portable generator of today should feature some type of eco-friendly exhaust system that minimizes the carbon footprint of the device. It’s impossible to make generators 100% ‘green’ yet, but there are some advanced tools that use solar batteries or run on biodiesel.
Many Uses of the Best Portable Generator
The world we live in runs on electricity, so a power outage, no matter how short, can be a huge problem. Large businesses and institutions, such as hospitals, restaurants, etc. have their own, stationary backup power sources that can keep them afloat in case of an emergency. The main reason to buy the best portable generator is to ensure that you also have the power to run all your most essential appliances during a blackout.
However, there are other situations when a quiet portable generator would be of great use:
-
Camping
Nowadays, you can make a trip into the wild a truly enjoyable experience, as you can get closer to the nature without relinquishing all the benefits of civilization. Quiet generators for campers are small, some under 40 lbs., so you can easily fit them into your trunk and carry the device to the campsite. They are powerful enough to support lights and cookers as well as charge laptops, smartphones, GPS navigators, and other gadgets. Please note that you would need to buy the best portable generator featuring the Clean Energy technology, as it’s the only safe type for sensitive electronics.
-
RV adventure
An RV generator is a must for every person who owns (or rents) this fantastic type of vehicle. These devices should be more powerful than the ones used for a short camping trip as they need to support more appliances. The best portable generator for an RV should be able to support the AC system, lights, and essential electrical appliances. You’ll also need a device with a larger tank and very efficient fuel consumption system so that it can support all the energy-reliant devices through the night.
-
Outdoor party
Super-quiet generators allow you to have a party anywhere. The device would power any kind of musical equipment and may even support a cooler to ensure a cold drink is always within reach. Advanced models of these devices are so quiet, you wouldn’t even hear them over the hum of conversation.
-
Construction works
The best portable generator can be used not only for fun, but for work as well. Building contractors, or any other professionals who must use various power tools at the sites disconnected from the grid can rely on this source of energy. This may increase the efficiency of their work as the majority of portable construction tools are less powerful than their corded counterparts. Having a good generator on-site solves the problem of energy deficiency.
The most important reason to buy the best portable generator is that it gives you some measure of ‘insurance’ for almost any situation. When you have this device in your home, you will be prepared to handle any energy-related issue.
Super-Quiet Generators: Types and Main Features
The types of generators usually differ based on wattage or fuel type. The vast majority of quiet portable generators produce about 2000 Watts of surge and 1,600 Watts of running power, so they are evenly matched in this regard. However, there are quieter models that give out only about 1,000 Watts max. They can be a good choice for short camping trips, but they can support only a few electric appliances for more than 4 hours, so this might not be the best portable generator for a backup power source.
When you need the best portable generator that is both small and quiet, you must settle for 2000 Watts max. Anything more powerful would be larger, heavier, and producing over 60 dB of noise.
Fuel types that can be used for the engines of portable generators include:
- Diesel
- Gasoline (gas)
- Sewage gas
- Natural gas
- Biodiesel
- Propane
The vast majority of the devices available on the market today run on gas and have a fuel tank capacity of about 1 gallon. This particular feature affects both the weight of the device and its running time. If you are looking for quiet generators for campers, you also need to consider the total weight of the fuel you have to take with you for the trip.
The best portable generator should be able to work about 8 hours on a single tank, but usually at a quarter or half load at most. The main advantage of a gasoline-powered engine is that the fuel itself is easy to come by. However, you need to consider that poor-quality gas would put a strain on the motor and may damage it in the long run.
When looking at the characteristics of the best portable generator, you’ll notice that the power of the device is expressed through two different numbers:
- Running Watts (usually 1,400-1,600)
- Starting/surge Watts (usually 2,000-2,200)
The ‘running’ power is the continuous output generated by the device. The other measurement indicates how much extra power it can produce. This is necessary for starting some types of electrical appliances.
The best portable generator of today must be extremely fuel efficient, and different models feature specialized solutions that improve this particular characteristic. You should consider buying a device with a power-output regulator. Some of the tools available on the market today have an automatic self-adjustment feature that switches between power modes based on the output. A manual system can be more efficient as you have full control of it, but only if you don’t forget to monitor the tool and switch the regimes when necessary. Features to look for:
- Electric Throttle
- Economy Mode/Setting
If you want to have the quietest portable generator, you will need to look one that has an inverter as well as a variety other noise-dampening features. Manufacturers use different methods to reduce the sound of the working engine, such as double-insulation or special cooling fans.
It’s very important to understand that even super-quiet generators aren’t completely noiseless. Usually, they produce between 50 and 60 dB of noise. This isn’t much, because a regular conversation is about 60 dB. While on a camping trip, the best portable generator is the quietest one, because it won’t attract unnecessary attention from local wildlife. The sound of rustling leaves is approximately 40 dB.
Extra Useful Features in the Best Portable Generator
Manufacturers introduce these particular features to make their products more efficient and therefore attractive to the buyer. They aren’t a necessity, but depending on your personal tastes and needs, it’s these extras that can make a difference for your final decision.
-
Spark Arrestor
This is a rather simple screen the main purpose of which is to catch sparks flying from the device. As an added safety-feature, the arrestor is extremely valuable, especially in quiet portable generators for campers. Remember that a forest fire can start with a single spark, and many of the camping tents are flammable. The best portable generator is always the safest one.
-
Alternative Fuel
The capability to use any fuel aside from its main type can be extremely valuable, and would truly be a great addition to the best portable generator. However, it’s a rare type of feature and the devices equipped with such capacity are usually rather big and cumbersome. There might be a possibility to ‘adjust’ your gasoline generator by using a specialized converter kit. However, it’s a huge risk, especially if you attempt to do it on your own.
-
Parallel Connection
This is a feature that allows connecting the same type of generator via a parallel cord in order to double the power output. The best portable generator would definitely have this capacity, but the cord itself is usually not included in the package. In most cases, you must connect the exact same model of the device for the system to work properly. However, some manufacturers offer a bit of leeway in this. The details should be explained in the manual.
-
Remote Start
This is a great feature for convenience, so the best portable generator definitely should have it. Unfortunately, majority of the devices on the market must be started manually. The Remote Start is a useful ability for home as it allows you to store the tool outside and not leave the house to turn it on or off. This would come in handy if the power outage is caused by a storm.
-
Transfer Switch
This switch isn’t included in the regular portable generator kit, but it’s an extremely useful thing, so you should consider getting one. The Transfer Switch connects the generator to the circuit box of the building. This means that using it will allow you to forget about problematic cords. You will only need to get the system unhooked when the power is back on. If you buy the best portable generator for emergencies, this is the feature you must have.
-
Manual Fuel Shutoff
This is a switch that allows protecting the device while it rests in storage. In simple terms, the switch traps fuel in the tank so that the engine can work out the parts that are trapped in the system. This will prevent dangerous leaks as well as ensure no part of the motor is damaged by spoiled gas. The best portable generator safety-wise must be equipped with some type of a fuel shutoff system. Some models available today shut down the fuel automatically. You can get this information from the manufacturer or seller.
-
Spin On Oil Filter
This feature is rarely mentioned because few devices actually have it. However, the best portable generator definitely must be equipped with one as this filter extends the service term of the system as a whole. On average, a device with an advanced lubrication system can last about three times longer than a regular generator. This benefit comes with a significant increase in price, so it won’t be a good choice if you are on a budget. You should weigh the long-tern benefits against the price to decide whether you need to buy a model with a better lubrication system.
Other important features that determine the quality and efficiency of a quiet portable generator are outlets and pollution level. People, who are conscious about the environment, should opt for CARB compliant devices. Some manufacturers add specialized solutions to make these tools more eco-friendly. They should be specified in the product details. Note that non-CARB compliant engines are illegal to use in some states.
The number and variety of outlets determine how convenient your power source really is. The best portable generator should have at least three outlets of the most commonly used types. In case you need the power for an RV, buy specialized RV ready devices as their outlet systems are a bit different.
Please remember that even the best portable generator wouldn’t last long if it continuously works at full capacity. This means you should switch it to the half or quarter load as often as possible. This would also help you save fuel and reduce emissions.
Important Considerations: Safety
Safety is a vitally important factor you must keep in mind when choosing the best portable generator. Every year, thousands of people all over the world die because of the incorrect use of engine generators. Most of these tragic incidents are caused by carbon poisoning, which occurs when a large engine is installed indoors.
A small portable generator is unlikely to cause such a tragedy as the carbon emission rate of its tiny motor is very low. However, it is still a device that includes an engine and fuel, so it’s a potential fire hazard by default.
You should always look for quiet portable generator equipped with highly efficient cooling and exhaust systems as they are directly responsible for reducing the risks associated with this type of device.
Other important safety features include:
- Low Fuel Shutdown
- Low Oil Shutdown
Both of them protect the engine from getting damaged by ‘running dry’. The best portable generator may be equipped with a fuel gauge and a low-oil alarm, so you can keep track of their levels easily.
Note that some devices require the use of specific types of oil. Usually, they are common automotive oils that can be purchased in any store. However, you’d better check the product’s exact specifications before buying.
Safety-wise, you must also remember to follow the instructions on correct handling of the generator. Install it within the recommended distance from your dwelling and remove all flammable materials from the vicinity of the device. Never cover the generator or leave it running in a room without efficient airflow.
If you have children or pets, make sure they stay away from the tool, even when it’s shutdown. Don’t forget to remove the fuel from the tank if you aren’t planning to use the device for a while.
