11 Smallest Portable Generators

Small generators that put out less than two thousand watts are useful for hobbies and recreation. They don’t provide enough power to run multiple appliances during blackouts because of their limited capacity, but their big advantage is their portability. Contractors, campers, farmers, and other people needing to work out in the field or areas with no electricity, will find them helpful in running a few power tools, work lights, and other equipment.

Some of the best brands for small, sub 2,000-watt generators include WEN, Honda, Westinghouse, Yamaha, Buffalo Tools, Pulsar, and Echo. Most small generators are incredibly portable and quiet. They are typically not the best as a backup power source but are great for recreational use.

Many of the smallest portable generators are inverters because they are more fuel-efficient and provide clean power for sensitive devices such as phones, laptops, and other electronics. Inverters generate alternating current (AC), convert it to direct current (DC), and then back to AC. They are generally more expensive than conventional portable generators because of their more complex processes but can save money on fuel and are much quieter.

It runs on gasoline and can run for up to twelve hours on economy mode without refueling. The generator comes with a three-year warranty when not used commercially.

The gasoline petcock allows the carburetor to run dry when you want to store it, preventing stale fuel from sitting for long periods and causing problems. A Smart Throttle senses the load and adjusts the revs accordingly to ensure greater fuel efficiency and noise reduction. In addition, there is an acoustically engineered noise reduction system that makes it one of the quietest portable generators in its class.

An Auto Warm-up feature increases the engine speed for a few minutes to ensure smooth power delivery with cold start-ups. Reviewers gave it a 3.9 out of five stars, with one reviewer noting that it was significantly cheaper than the Honda and started quickly every time.

Another reviewer warned that while it is a really nice generator, it might not be a good backup generator for an RV because you should not use the 12V output to charge batteries of a higher capacity than 40Ah. Also, if you use this generator in the mountains, the engine may require a high-altitude carburetor kit to ensure correct operation above 4000-foot altitudes.

It had several five-star reviews from users who commented on its fuel efficiency, quietness, reliability, and portability.

6. Lifan ESI 860i-CA

This generator is one of the smallest out there and weighs only twenty-three pounds. Start-up watts are 700W while running watts are 600W. It has a four-stroke 40cc OHV engine that provides three hours of run time at half load. Noise levels at twenty-three feet are around fifty-eight decibels. There is only one AC outlet on the control panel and a 12V socket for battery charging.

It is an inverter, so it is safe to use with delicate appliances such as mobile phones and laptops. There is a low-oil feature and an overload preventing circuit breaker. A full tank of fuel yields up to five hours of operation, and it has a recoil start. The fuel tank holds 0.4 gallons of fuel.

Walmart reviewers gave it 2.7 stars, while reviewers have given it only 2.6 out of five stars. One said that although it is a great generator, its assembly leaves much to be desired. The electronics were clean, and none of the internal components looked shoddy, but the manual isn’t good, and the one he ordered came with a broken ignition coil mount, a broken exhaust manifold, and a black spark plug. Another said he used it for around fifty hours before it bricked itself.

7. Westinghouse iGen 1200 Portable Inverter Generator

The Westinghouse iGen 1200 weighs only thirty-three pounds and has a good build quality. It puts out 1000 running watts and 1200 start-up watts and is CARB-compliant.

It is equipped with circuit breakers to prevent overload, and it is CARB-compliant and EPA-approved. Price-wise it is inexpensive and is recommended for hunting, fishing, boating, and camping.

Another satisfied customer said he’d had his for ten months, and it had never let him down. After using it, he cuts the gas valve off to ensure that the carburetor empties of fuel before storing it and says the quality looks pretty good. He has powered a drill press, large shop fan, band saw, bench grinder, angle grinder, radio, and three fluorescent lights on it. Its overall rating was 4.2 out of 5 stars. It did get a few negative one-star reviews from people who said it broke quickly and wasn’t worth the money.

A few Walmart reviewers gave it five-star ratings in 2021, and its overall rating was 3.4 stars.

10. WEN 56105 Portable Generator

The WEN 56105 is another one that is not an inverter and has a two-stroke engine which means it runs on a mix of gasoline and oil.

What to Look for When Buying a Small Portable Generator

When buying a small portable generator, you need to think about what you want to use it for and where. There are many attributes and features that you must pay attention to when choosing a small generator, so here are a few especially important things to consider during your search.

Generator Noise

Noisy generators don’t go down well in campgrounds and parks, so if you’re going to use them for recreation, bear this in mind. Some campgrounds won’t allow a generator at all because they disturb the peace.

A fifty-decibel generator is very quiet and operates below the level of normal conversation in a home to give you an idea of loudness levels. You can compare sixty decibels to the sound of laughter or the noise of people in an office. Anything over sixty decibels is starting to get loud, and seventy decibels, the sound of a vacuum cleaner, for instance, is unpleasantly loud.

A portable generator operating in the fifty-decibel range is barely noticeable. When the manufacturer specifies a generator’s noise levels, the sound output is most often measured from twenty-three feet away. You can hear a sixty-decibel generator from several hundred feet away.

Generator Type

Conventional generator engines running on gasoline or propane run at full speed regardless of the load. In contrast, inverter generators can adapt the engine speed to the actual load, making them a lot quieter.

Conventional generators also do not have much sound-dampening built-in, and the mufflers are usually cheap and noisy. Therefore, small portable generators are best used around the house to power lights, fans, and other non-sensitive appliances or out in the field for small tools, crafting equipment, and pumps.

It is better to buy an inverter generator to use at campgrounds and parks, even though they are more expensive. Anything above sixty decibels is likely to get you into trouble, and you usually cannot use it by camp rangers and neighbors.

Generator Power

Many people buy a generator with the wrong expectations and get frustrated when it doesn’t meet their power needs. You should always do your research, armed with a rough calculation of how much power output is necessary for your particular activities. Small camping generators cam power lights and portable refrigerators but don’t expect them to power your RV’s air-conditioning unit.

Generator Weight

Small generators weigh a lot less and can usually be carried without much effort by one person. This makes a difference if you are going solo fishing or hunting. Portable power stations are not covered in this article as they are not, technically speaking, generators but large re-chargeable batteries that you can use to transport a certain amount of power to sites away from home.

Generator Use

Small portable generators can provide emergency operation of fridges and freezers, preventing food spoilage during blackouts and have low running costs. However, they have small fuel tanks, so you need to think about run time and refuel often. They are all designed for temporary use, so they may not be suitable if you have prolonged power outages in your area.

If you only want it for the odd outdoor event or tailgating party, then a small portable generator will fit the bill. They will only power the bare minimum for household appliances and are probably not ideal as backup generators compared to their medium-sized relatives. You must manually start them, and you cannot use them indoors because their carbon monoxide fumes are deadly.

Usage Environment

The type of environment in which you will be using the generator is also a consideration. If you are exposing it to rough weather conditions, look for one with sturdy housing. If you need a portable generator to power a home office for long periods, it would be better to get a medium-sized or even large one if you have frequent power outages. The small ones are only really suitable for emergency use.


Small portable generators are available for various applications ranging from hobbies and recreation to small construction jobs and DIY projects. They have the advantage of being highly portable, fitting easily into the trunk of a car or the bed of a truck, and inverter generators can power essential electronics such as laptops, cell phones, cameras, and routers. Most of all, they generally have much lower noise levels than their larger cousins.
