What is a Portable Generator? 

Before you go out in the market to look for a generator, you have to know which one you want and think about how and where you will use it.


There are different types of generators, from portable inverters to standby generators. Purchasing the right generator will help you operate various appliances without any hustle. 


Today we are dealing with portable generators. Portable or backup generators offer temporary power when needed in an emergency or outdoors. This is just a relative term for portable generators because some generators are more mobile than others.


While the small generator models can be carried, most portable generators feature a carrying handle and heavy-duty wheels that make transport simple. 


Portable generators have multiple power outlets to plug extension cords, electrical power appliances, and sensitive ones. Unlike the standby generator systems, they are not installed permanently, can be moved anywhere, and can be manually started.


They are rated in watts, and the more the watts, the more items you can power. A typical portable generator has the following components when fully assembled in a single unit: 

  • Starter
  • Internal combustion engine 
  • Alternator 
  • Outlets
  • Fuel tanks


Because you don’t know when you will require a portable generator to power your device, you have to maintain it to make sure it is ready to work. There are different methods you can use to maintain a portable generator, such as:

  • Using a fuel stabilizer to prevent gum from forming and blocking the fuel system 
  • Change your generator oil to keep it running smoothly 
  • Inspect all the replaceable parts regularly. 

How Does a Generator Work?

Portable quiet generators are reliable machinery that offers consistent power for different situations, whether keeping lights on during a blackout, providing electricity to a Jobsite, sporting event, campsite, and many more.


They offer reliable electricity using a gas engine and are more versatile than standby generators installed permanently. So, how do generators work?


Generally, generators don’t create electricity. Instead, they convert chemical energy into clean electrical energy. They capture motion power and turn it into electrical energy by forcing electrons from an external source through an electric circuit. In short, a generator is an electrical motor functioning in reverse. 


A generator contains the following primary components: 


Combustion engine: This is the workhorse of a generator. It determines how much power a generator can provide. 


Alternator: The conversion from mechanical energy to electrical energy occurs here. It contains both moving and stationary parts that work together to create the movement of electrons that generate power. 


Fuel system: This makes it possible for the generator to generate energy. A fuel system includes a fuel pump, a fuel tank, a pipe connecting to the pump, and a return pipe. Besides, it has a filter that removes debris before it gets to the engine. 


Voltage regulator: It is a valuable component that controls the voltage of the electricity produced. Still, it helps convert the power from AC to DC if needed. 


Control panel: A control panel monitors every operation of the generator from startup and running speed to outputs. Modern boards are more improved, and they have safety features that alert you or shut the unit down when the fuel level is low. 


Lubrication system: A generator has multiple moving parts inside. They need to be lubricated adequately with engine oil for a smooth operation and protect them from wear. So, a generator should have a good lubrication system. You should keep checking the lubricant levels, mostly every 8 hours of operation. 

What are the Advantages and Disadvantages of a Portable Generator? 

Electricity is an integral part of our everyday lives that we overlook. Sometimes we forget how much we need and depend on it. Only when there is a power outage problem do we know how important electricity is. However, you can solve this using a portable generator. Here are some of the pros and cons of a portable generator. 



  • Generators offer a reliable power supply. 

Power generators provide clean electricity at any time. Therefore, you will always have backup power in case of a power problem. This way, you can continue with your daily activities. 


  • Flexibility

Unlike traditional generators and models that need permanent installation, a portable generator gives you the flexibility to use it anywhere.


They weigh less, are equipped with sturdy moving wheels and comfortable carrying handles. You can use it both indoor and outdoor with all these features, provided it has everything it needs to run. 


  • Portable generators prevent losses. 

If you primarily rely on power for a living, having a performing portable generator will help you avoid losses. You only have to switch it on in a power outage and continue your everyday operations. For example, a home will prevent the food stored in a refrigerator from spoiling or powering your smart devices. 


  • It can be used to charge multiple devices. 

Unlike some traditional generators that cannot charge sensitive electronic devices, portable generators can charge almost everything. Portable quiet generators have built-in safety features that protect your devices from overcharging, short-circuiting, and other dangers.


This way, you can use a portable generator to charge most of your devices, including a phone, laptop, fan, drone, car fridge, LED light, digital cameras, MP3, and other smart devices.



  1. Because a generator uses fuel, it will release combustion gases. Remember, no fuel, no generator. You have to use it in an open place to avoid the combustion gases. 


       2. When purchasing a generator, most manufacturers say it is an ultra-quiet generator, but this is always not true. Some generators are slightly loud, and some are extremely loud. Depending on the model you purchase, the noise level can be more or less intense. 


         3. A generator needs electrical installation to connect it to the home network. If you don’t have the required knowledge in the field, doing the installation by yourself will be tricky. That is why it is always advisable to buy a product with an instruction guide and installation manual. 


         4. Generators must run on gasoline, diesel, or propane on fuel. Meaning, you will require to store a certain amount to keep you ready for an emergency. If not enough, the generator will shut off. So, on the downside, a generator requires a certain amount of diesel fuel or gasoline to run for a certain period. 


        5. When used regularly, it requires regular maintenance, which can be costly. 

Buyer’s Guide

There are many portable generators in the market, and choosing the right one can be tricky. The portable generator you want to purchase should offer reliable power that will suit all your power needs. Below is a guide with the nine crucial factors to consider before buying a generator. 



Portable quiet generators are lifesavers. They are backup power sources that convert gasoline, diesel, or propane gas into energy. A portable generator is helpful in many ways. Depending on your application, you will purchase a medium or powerful generator.


In our guide, we have the best generators that can be used to charge multiple electrical devices, such as TV, laptops, mobile phones, LCD TVs, tablets, power banks, lamp lights, and many more. 


Besides charging devices, you can use a portable generator outdoors in a campsite, hunting, tailgating, hiking, sporting events, boating, family occasions, standby power for business, and emergencies. 


Power Output 

Before you purchase a portable generator, you need to know the size you need. Meaning, you have to know how much power you need. Because you have different appliances to power, the power output is critical.


For instance, a refrigerator needs 700 watts to run, but what happens when it needs 2100 watts of starting power? Therefore, you have to be keen on the startup watts required to run the appliance you want to power and the running watts. 


You have to know the type of outlets you need. Smaller generators have 120V AC outlets and USB ports to charge smart devices. With up to 4000 watts, you will see 240V plugs that show along with 120V outlets. Since the generator will be used outside, it should have GFCI protected outlets. 



Portable generators are powered by diesel, gasoline, or propane. It is always good to look for a generator converted to propane use. Still, propane is environmentally-friendly and very reliable. You can recharge some models via a solar panel, and they have no emissions. However, these are expensive, charge slowly, and offer more than 2000 watts. 


Noise Level

Generators come in different sizes. Depending on how it is built, the bigger the size, the noisy it is. Smaller generators have a subtle design that offers smooth operation.


Buying a generator of more than 4000-watts guarantees no quietness, and you have to know how to handle the noise level. Diesel models make more noise than gas models. However, improved generators in the market are equipped with enhanced features that ensure a noise-reduced operation. 



Multiple factors determine the run time of a portable generator. Some of the factors include the appliances you are charging, the time taken to charge, and the amount of gasoline or diesel it has.


For instance, if you are charging larger appliances, they will drain the power faster than expected. Luckily, you can anticipate this by ensuring you have ample gasoline or diesel. Smaller devices tend to use less energy, and they charge fast. 


Size and weight 

Portable generators come in different sizes and weight capacities. Most of them are lightweight and compact to allow easy carrying using much energy.


Despite people’s belief that large things contain more power than smaller ones, you can find small-sized generators that power any appliance no matter its size. If you don’t have much storage space, buy a compact model to store anywhere without needing much space. 



This is another crucial thing you should not overlook. For the generator to offer good performance for years to come, it should be fitted with reliable safety features that will keep it protected, plus the devices you need to charge.


For example, your devices should be protected from overloading, short-circuiting, overcharging, over-voltage, lock-on protection, and over-heating. In addition, it should be equipped with a sensor or alarm that alerts you when the fuel level is low to protect the engine from damage. 



There are many generators in the market, and they have different prices. The price of a portable generator is designed by its output, noise level, design, construction, safety features, size, and versatility.


Of course, you will have to pay more money for fuel-powered generators because they offer adequate power. Still, the portable models with higher wattages have a higher price. So, you have to know what your budget level is and decide which one to purchase.
