20 best gasoline generators of 2021: rules and mistakes when buying

Every resident of our country has at least once faced the problem of turning off the light. At such moments, you realize how much we are dependent on electricity. However, technology and science are advancing very rapidly. With the help of our article, you can choose the best gasoline generator for yourself.

What is a gasoline generator for?

The gas generator is irreplaceable in case of complete or partial power failure. It is often used on construction sites where it is not possible to connect to a power source to ensure the normal operation of construction tools. Also, the device is often purchased for summer cottages or private houses. The generator runs on liquid fuel, converting mechanical energy into electrical energy.

In this video, an expert will tell you how to choose the right generator.

Pros and cons

Often, potential buyers cannot choose the type of generator they need. The main dilemma is between diesel and gasoline models. All of these power plants are good, but the advantages and disadvantages are easier to spot by comparison.

Pros of a gas generator:

Good power / size ratio. With their small size and weight, gas generators have a high power up to 10 kW. In addition, they can idle, unlike diesel models.
Ease of use. The operation of gasoline power plants does not require additional technical knowledge. To get started, just start the engine and check the oil level.
The devices are very easy to maintain. It is easier to find spare parts on them, as well as to repair in case of breakdown. The same diesel requires narrower specialists and rare parts. An added benefit: it doesn't take a lot of effort to keep it up and running.
Work in the cold. Even at low temperatures down to -25 ° C, gasoline-fueled power plants start up with ease, which cannot be said about diesel models.
Low noise level. A very important indicator, since high decibels can significantly affect the choice of the device. Compared to a diesel engine, petrol generators are one third quieter.
Affordable price. Unlike units operating on other types of fuel, gasoline units cost almost half the price.

Cons of gasoline power plants:

High economic costs. High power generators require more fuel consumption, which translates into overall operating costs. Since gasoline is much more expensive than diesel, this factor is not in favor of gas generators.
Compared to diesel models, they need frequent breaks between uninterrupted operation.
Requires additional protection. When operating outdoors, the petrol power station must be protected from direct rain, snow or other precipitation.
The need to regularly drain fuel from the tank. The device of the gas generator does not provide for the constant presence of gasoline in the fuel container.

Criterias of choice

What requirements should the best model of a gasoline generator meet? We will try to answer this question by understanding the main selection criteria.

Number of measures

In simple terms, gas generators are internal combustion engines. There are two types of models on the market:

two-stroke;
four-stroke.

Units that have two clock cycles declared are simpler and also cost less. In such engines, there is no gas distribution and lubrication systems. Another plus of two-stroke generators is that they accelerate faster to maximum power. However, the simplicity of the device has its drawbacks:

increased noise;
shorter service life compared to a four-stroke engine;
high fuel consumption due to its partial emission along with the exhaust;
low environmental friendliness;
the need to pre-prepare fuel for refueling by mixing gasoline with oil and strictly observing all proportions.

Power

One of the main parameters when choosing. It is calculated by simply calculating the total power of all electrical appliances that will be powered by a gas generator. To determine the minimum active power of the unit, it is necessary to add another 20-30% to the obtained indicator.

According to this criterion, several types of devices are distinguished:

0.5 kW (inverter, for going outdoors);
up to 3 kW (suitable for powering a refrigerator, TV, light bulbs);
3-5 kW (for working in a workshop and providing electricity for a small cottage);
over 5 kW (power a large room with many electrical appliances at the same time).

It is very important to calculate the required power, since if it is incorrectly calculated, the risk of overheating of the device, its sudden stop increases, fuel consumption increases, and wear and tear occurs much faster.

The total fuel consumption also depends on the power. The higher the indicator in kilowatts, the less economical the generator becomes. The volume of the tank does not affect this parameter. It only indicates how long the unit can operate at one gas station. More volume implies an increase in the overall weight and size of the device.

Working conditions

The gasoline generator is a rather noisy unit. If you are going to use it at home, then it is better to choose a model with a soundproof casing and an anti-vibration system. The permissible noise level of the power plant should be between 55 and 75 dB. When working outdoors, this indicator does not matter.

An important parameter is the battery life. It shows how long the generator can run from one fill to the next. In addition to the volume of the fuel container, the indicator is also influenced by the amount of energy consumed. Four-stroke units with a 20 liter tank can operate continuously for 10 to 15 hours.

Low-power units consume significantly less gasoline, but their operating time is reduced to 1-3 hours.

Additional functions

To improve the performance of gasoline generators, manufacturers are equipping them with additional features. So, a power plant can have one or several startup modes:

manual;
electric;
auto.

Cheap models are equipped with a manual start and are suitable for infrequent use in the country or in the garage. For a private house, it is better to choose a power plant with an automatic starter. It allows for easy start-up and provides information on the required performance indicators.

Most power plants are produced with one phase. They are suitable for a conventional 220 V.

In order to increase the service life, special protective systems are installed on the generators:

For cooling. Most models are fitted with an air engine protection system. It is economical and easy to operate. However, there is also a liquid one, which is used on expensive high-power devices.
Congestion control.Protects the unit from short circuits due to overload or power surges. The electronic mechanism automatically stops the generator when critical values are reached.

Power stations for welding machines have one feature - they are equipped with a system that allows, when starting, to supply a current three times higher than the indicated indicator.

The main mistakes when choosing

A gas generator is a complex unit that needs careful selection. Potential buyers often make the same mistakes, and in order to protect you from possible risks, we will tell you about the most common ones:

Peremptory trust in a consultant. Since the main task of the seller is to sell you a product, he will agree with any decision you make. You should only listen to him when he tries to argue with you or offers a reasonable alternative.
Mistrust. The flip side of the first mistake. If the consultant talks about the pros or cons of the product, he must be able to substantiate his arguments. These can be references, facts or any other adequate argumentation.
Purchase at regular stores. Firstly, they do not have the same assortment as in online stores. Secondly, they do not provide service. In addition, the cost of offline goods can be significantly inflated due to logistics or other factors that influence pricing.
Orientation to the country of origin. According to statistics, 95% of all generators are assembled in China. What you are offered under the brand name "Germany" or "USA" is nothing more than siphoning off money. Therefore, you need to choose a model by brand, and not by country. It is he who acts as the guarantor of quality and reliability.
Selection by characteristics on the site. Blindly trusting all the information written on the site where gas generators are sold is not worth it. To increase sales, the characteristics may be overstated and not true. The only factor that at least somehow tells about the quality of a product is its price.
Choice based on internet reviews. Since most of the reviews are custom-made and are written for money, there is little truth in them.
Rely on price alone. Not always an expensive gas generator is of high quality. Some manufacturers make large markups on their products, while others, on the contrary, lower the retail price. It is best to rely on a conscientious consultant in this matter.
Buy a power plant on the advice of a friend. Even generators of the same model may have different lifetimes. It depends on the manufacturer, batch, parts and the good faith of the manufacturer. If the device does not break before the warranty expires, this does not mean that it will not break later.
Give preference to inverter generators. Units of this type are only suitable for fishing or picnic. If you want to light your house and connect electrical appliances to it, it is better to take the classic model with 3000 rpm.
Ignoring weight. The more the device weighs, the more powerful it is. A 35 kg power plant cannot deliver a power of 5 kW. Therefore, when buying, carefully correlate these two parameters.
The choice of a little-known manufacturer. The high quality guarantee of the gasoline generator is the name of the world brand. If the brand is sold in large American, European or Asian networks, this is a reason to pay attention to such a device.
