How Do Portable Gas Generators Work?

The mechanism of a portable gas generator is quite easy to understand. The unit takes gas and converts its magnetic energy to electrical energy. And it supplies the current to power your appliances. Let’s quickly talk about the main components of a portable gas generator and its functions.

Engine: This is the main part of the generator that converts magnetic energy to electrical energy. The engine is more or less the generator itself.

Fuel Tank: Every generator has a fuel tank in which it stores the fuel of the generator. The tank has a hose or tube through which the fuel will enter the engine from the tank. In an industrial generator, the fuel tank is referred to as the fuel system.

Voltage Regulator: This component regulates the voltage being supplied by the generator. It prevents high voltage, low voltage, or fluctuating voltage. If your generator starts supplying a low voltage, your voltage regulator may be faulty.

Recoil Start Assembly: This component has a cord wound around it. The cord has a handle. This is where the generator is started. After doing the needful, you have to pull the cord swiftly. The generator will start at once.

Spark Plug: This plug helps to ignite the generator. If the plug is dead or dirty, your generator won’t start.

Battery: The function of the battery is to start the generator using the key. If the battery is weak or dead, you won’t be able to start your generator with its key. However, the recoil start does not require a battery.

Having listed the major parts of a portable generator, let’s discuss how it works. Once the generator starts running, the engine generates a magnetic field and converts the magnetic energy to electrical energy.

How Is a Portable Generator Powered?

There are two main types of portable generators. One type of generator is powered by fuel, while the other type is rechargeable. The rechargeable type of generator is also known as an inverter generator.  The inverter generator has an in-built battery. When the battery is weak, it will indicate, and you’ll charge it by plugging it into an outlet.

The other type is the generator that is powered by either gasoline or natural gas. That type of generator has a fuel tank. In fact, some generators are fueled by both natural gas and gasoline. You get to choose which of the fuel types you’d stick to.

If your generator uses gasoline, we suggest that you always fill its fuel tank to capacity before using it. Don’t wait until it runs out of fuel while using it. Although the generator will shut down whenever it runs out of fuel, it’s not a good idea. Once the fuel finishes, the generator may suck some dirt before going off. Over time, the dirt will accumulate in the engine and reduce its performance.

How Does a Portable Generator Power a House?

To make your generator power your house, you have to connect it to either the transfer switch or breaker box. First, an outdoor socket is installed. The generator cord is plugged into the generator outlet, and the other end of the cord will be plugged into the outdoor socket.

The socket is linked to the transfer switch. When there’s an outage, you’ll start your generator and plug the generator cord from the generator to the outdoor socket. Then, you can flip the transfer switch from the main supply to the generator.

When power is restored, switch off the generator and remove the plug. Then, flip the transfer switch back to the main supply. Nowadays, there are automatic transfer switches that do not require manual operation.

How Long Will a Portable Generator Run on a Tank of Gas?

How long your generator runs depends on the following 4 factors.

  1. Rate of fuel consumption: Some generators consume fuel faster than others. You need a generator that will conserve fuel. It will reduce the amount of fuel you’ll buy.
  2. The fuel tank capacity: The amount of fuel the tank of a generator can take matters too. Generators with larger fuel tank capacities will work for a longer period before running out of fuel.
  3. The amount of fuel in the tank: The more the amount of fuel in the tank, the longer a generator will run. If your generator has a full tank, it will run twice longer than when it has a half tank. That’s if you put the same amount of load on it.
  4. The amount of load: This should be pretty explanatory. The more the load, the higher the rate of fuel consumption. And when it runs out of fuel, the generator will shut down.

In general terms, a portable generator runs for about 5 – 12 hours. In fact, some can run longer than 12 hours, but it is better to allow your generator to rest after 12 hours.

Buying Guide – How to Choose the Finest Portable Gas Generator?

How to Choose the Finest Portable Gas Generator

The best portable gas generator for one person may not be all that good for another person. It all depends on your particular circumstances and needs. To pick the right one that’s best for you, these factors must be considered:


You have to consider the running (or rated) watts as well as the peak (or starting) watts. This is the most important consideration, as this will determine what kind of appliances (and how many of them) you can run with the generator. With enough wattage, you can run the usual appliances of an entire household during a power outage.

Running Time

This is usually determined by the size of the fuel tank and the efficiency of the motor. This will also depend on the load you’ve placed on the generator. Normally, you’d expect a gas generator to run for about 8 hours at 50% load.


This normally isn’t a problem, as these generators generally have wheels and a handle. But the weight may be an issue if you’re going alone to a camping site and you need to lift the generator from the car trunk.

Ease of Use

Again, this shouldn’t be a problem. Even average gas generators should be easy enough to figure out by most adult users. They’re usually so simple even children can use them.

However, it’s best if you do have easy to read gauges and indicators for engine and fuel status, and if you also have lots of safety features like auto low oil shutoff.


The bigger ones with the most watts tend to be noisier, so it’s up to you to balance your need for power vs. your need for peace and quiet.

You should be able to get used to a gas generator working at 70 decibels or so, which is as loud as a vacuum cleaner. But some generators don’t make as much noise at all.


How long will the unit last? You may want to stick with well-known brands or to generators made in countries known for good quality control. The length of the warranty can also indicate how long the generator is expected to last.

Who Makes the Quietest Gas Generator?

One of the main drawbacks of using a gas generator is that you have to deal with the noise. It’s one thing to use a rechargeable power station to power your appliances. When you deal with a motor that runs on gasoline, noise is generally part of the deal.

But some generators are noisier than others, and some are run comparatively quieter. Usually, you can thank your lucky stars if your gas generator makes about 70 decibels.

That’s about as loud as a modern vacuum cleaner, or when you turn on your TV at normal sound volume. Some of the more silent gas generators emit even lower noise levels.

  • The HONDA EU3000IS can run at less than 50 decibels. That’s as noisy as a quiet suburb which means it’s very quiet.
  • The Yamaha EF2000iSv2 goes only up to 61 decibels even on a full load. That’s the normal sound volume of a typical office. It’s about as noisy as an air conditioner 100 feet away from you.
  • The Champion Power Equipment 73536i is also good at 53 decibels.

Take note that these decibel readings were taken from 23 feet away. So you may want to get the hint and place your gas generator far from where you usually sit.

Final Verdict

A gas generator is one of those must have items in your home. Sooner or later you’re going to need one because you’ll have a power outage.

These generators are best portable generators for camping, picnics, tailgate parties, beach outings, so you can still have lights, music, and the use of your beloved coffee machine.
