When a storm hits and the power goes out, generators from one of the best generator brands can keep out hours in the dark. Depending on size, a portable generator can provide up to 15,000 watts of power to keep the lights on and power air conditioners and refrigerators. A good generator is only "good" if it is reliable.

With so many brands on the market, finding a product that provides reliable backup power without breaking the bank can be challenging. Keep reading to learn more about some of the best generator brands and top generators on the market.

1. What is a Generator?

Generators are one of the useful devices that provide electrical energy during power outages and prevent interruption of jobs and operations day and night or interruption of operations in different conditions and locations. All a generator does is convert mechanical energy supplied from an external source into electrical energy to provide enough power for other devices. It works based on Faraday's law of electromagnetic induction.

This law states that wherever a conductor is placed in a different magnetic field, magnetic flux will be induced. There are different electrical and physical configurations for the generator. This variety of configurations is used in different applications. In the following sections, we will detail how a generator works, its different types, and what parts a generator consists of. Read on to get acquainted with the world of this amazing device.

2. Types of Generators

There are 3 main types of generators: portable, inverter, and standby. Portable generators and inverters can power a variety of tools and on-site equipment. Please choose the size you need based on the active wattage of the items you'll be connecting them to and the power spikes when starting them up. Standby generators have some differences from the other two. They are standby for residential, industrial electrical and commercial systems. Safety precautions should be taken to reduce operational hazards.

Portable Generator

Here are some features to note about a typical portable generator:

  • Most run on gasoline, but a few run on diesel fuel, gas/liquid propane, or even gas/liquid propane/natural gas.

  • Half-load runtimes range from about 8 to 32 hours, though most are between 10-15 hours.

  • Most of them will power 120 or 240-volt applications

  • They are capable of withstanding a variety of harsh environments.

Inverter Generator

Some common characteristics of inverter generators are as follows:

  • Almost all run on gasoline.

  • Most models only power a 120-volt outlet, so they typically power smaller or more sensitive appliances and electronics than a portable generator.

  • They are more energy efficient than conventional portable generators, as the motor speed adjusts according to the amount of power required.

  • Inverter Generators are smaller and lighter than portable generators, they can fit in a car, boat or RV.

  • There are also dedicated battery-powered inverter generators that can run wired kits.

Standby Generator

A standby generator is an active electrical system with a toggle switch that commands it to operate automatically in the event of a power failure.

Some characteristics to note about generators are as follows:

  • They operate on diesel fuel, natural gas, liquid propane or some kind of hybrid.

  • They are permanently installed and not portable.

  • Single-phase models support commercial or residential systems, while three-phase models can power industrial systems.

  • Remote monitoring via a smartphone app.

  • Many people will perform weekly automated checks to ensure that they will react properly during a power outage.

3. Components of Generators

So far, we are familiar with the working principle and different types of generators, and gradually we are getting closer to the answer to the question, "what is a generator?" In this section, we are about to acquaint you with the main parts of a generator.


The most important part of every machine is the motor. It is usually part of an entire system that converts fuel into usable energy and helps it move or perform its mechanical function. Therefore, the motor is sometimes called the main engine of the machine. 

A generator's engine fuel source can be gasoline, diesel, natural gas, propane, biodiesel, water, exhaust gas, or hydrogen. The engine uses one of these fuels to generate mechanical energy that the generator converts into electricity. Some engines commonly used in generator design include reciprocating, steam, turbine, and small engines.

Fuel System

All Generators running on one of the different fuel types mentioned earlier have a system that collects and injects fuel into the engine. The fuel system contains a tank containing enough fuel to power the generator for an equivalent number of hours. There is also a pipe connecting the fuel tank and then the engine and a return pipe connecting the engine to the fuel tank to return champion tri fuel generator review.

Generators and Stabilizers

We can say that the main job of the generator is by the alternator. This unit converts the mechanical energy generated by the motor into an electric current. An alternator consists of a stator, a fixed part of a set of windings, and a rotor or armature that generates a stable rotating electromagnetic field around the stator. In general, AC generators produce a voltage that must be adjusted to produce a constant current suitable for use.

Cooling, Exhausting and Lubricating Systems

There is a cooling system to prevent overheating and regulate the temperature of the generator parts during use. Some review champion generators use a fan, coolant, or both to control the temperature of the generac 3300i reviews while it works.

As the generator's combustion chamber converts fuel, the generator will also produce emissions. The exhaust system removes the harmful gasses emitted by the generator during use. The last part is the lubrication system.

4. Top 3 Generators Brands of 2023

We have prepared this list of the most reliable generator brands by considering many factors such as technology, reliability, efficiency, convenience, cost, and warranty.

Honda Generators

Just browse Honda's range of portable generators, and you'll see why they're the most sought-after. Compact design, powerful engine, high fuel economy, and sturdy frame. All the qualities you want in the best quality portable generator.

Moreover, Honda is one of the first generators brands to produce quiet engines for RVs and domestic champion power equipment review. This makes it the best choice when it comes to both commercial and domestic applications.

Yamaha Generators

There is a joke on the Internet surrounding the fact that this 19th-century Japanese company is the largest piano manufacturer in the world and a motorcycle company. But it is also a global household name for electrical appliances and tools. Its USP lies in the muscles and the intellect the company manages to put into its products through cutting-edge research and development, thus also creating stiff competition with the small generators brands domestic compact, Honda.

However, both brands have a distinct style and vision, reflected in the factory's tools and equipment. For example, check out this 1,600-watt portable inverter, the epitome of the best small champion 4500 inverter generator reviews, champion 2500 watt inverter generator review, champion 2000 watt inverter generator reviews, champion 7500 watt generator reviews, champion 4650 inverter generator reviews for home use. At a glance, the uninitiated would assume it's a media player from the mid-2000s.
