10 things you Must Know Before Buying Portable Generators

Whether you are planning to buy a generator for emergency power or to run work site or to have a recreational use, there are plenty of things to consider when buying a portable generator. So to help you know how to pick a generator among the plethora of options out there, here are few things to concentrate on before you purchase a portable generator.

Noise Level

No one likes the noise. How much noise the generator produces can be one of the factors that you have to consider before you purchase the generator. Of course, a quiet generator will be preferred by all consumers if everything else is equal. Generally, small size generators have the option of a quiet design. If you’re tailgating or camping in an area that allows generators, your neighbours will appreciate the consideration.

Read our Detailed Post onWhat size of portable Generator Should You choose ?”

Fuel Tank

The bigger the fuel tank, the longer you could go between refuelling. Most of the portable generators have a fuel tank that will give you 7 hours to  9 hours of runtime at a 50% load. You will run longer if you use a lower percentage of the available power and shorter if you use more. Given a choice between a smaller and larger tank, it is best to go for larger.

Wheel kits

Most of the generators will not come with a wheel kit. Some require you to purchase the wheel kit separately, so make sure that the generator you buy has wheel kit.

Requirement of voltage

General low voltages of the generators are 120/208 volts three phase, 120/240 volts single phase, 277/480 volts three phase and 120/240 volts 3 phase. If you are unsure of it, then your electrician can provide this information.

Fuel Type

Diesel generators will give you better fuel efficiency if you are willing to pay for the upgrade – plus you lose the carburettor that always seems to be clogged at the least convenient time. If you are thinking about a whole-house generator, you will be looking at diesel. Keep in mind that diesel isn’t as easy to find as gasoline.

Warranty duration

The standard warranty for the portable generator systems typically ranges from 1 year to 6 years depending on the generator type. On the other hand, industrial generator comes with a one or two year warranty along with operational upgraded. Whereas, the residential generator come with a warranty of two to five years and offer optional upgrades. Before you purchase a generator, it is best to understand the warranty duration and coverage of your standby system.

Who will install the equipment?  

It is always better to choose a reputable company that provides installation of generator also. Some purchasers may have a company in mind when deciding to purchase a generator while others may benefit from a referral.

Fuel gauge or fuel level monitor

This feature in generator allows the user to check the fuel level at a glance. It is a very convenient and handy feature to have during long power outages. By this, the user will know just how much more fuel is left in the generator and when to refuel.

Oil Guard

Choosing the generator that could shut down automatically when the engine oil level runs low is very beneficial. This feature of the generator protects the engine from any damage by shutting down the generator if the generator oil level falls below the minimum. However, only more expensive models offer this feature.

Number of outlets

The more outlets the generator has, the better it will be for the user. Three or more outlets provide the best use of a generator’s wattage by spreading the load.

Apart from the above-mentioned points, it is also very important to consider how long can a Generac generator run continuously.


How Much Power Do I Need?

To determine your basic home power needs, just think of a few questions – Do you use well water or city? Is your heating system electric, heat pump, or gas or oil forced air? And Is your hot water heater electric, gas, or oil fired? Homeowners can often power most of their household appliances using between 2500 and 7000 watts. If your house has any little furnace and city water, you can generally expect that 2500 watts to 5000 watts will cover your needs. If you have a good pump or larger furnace, you will likely need a 5000 to 6500-watt generator. Another primary factor you need to consider is the size of your AC unit(s). Also check the power requirement of your blender, coffee pot or other appliances you want to use. To determine your power needs, check out the wattage estimation guide in google that can help you to build a quick estimate.  Appliances with electric motors need additional power to start.


Types of Generators and their Properties

Electric generators are very essentially systems, and in fact, they are of lifesavers. Generators are backup power sources that convert fuel supply—usually gasoline, diesel, propane, into electrical energy. These systems are the primary sources of electrical supply during power outages. This energy is used in an external circuit. Apart from standby generators, the following generators are not permanently installed in one place, so they are easy to start.

Types of Generators

Mainly, there are three types of generators available: standby, inverter, and portable. Despite few differences, all these three generators generally undergo same maintenance to ensure long-term use.

#Portable Generators

A portable generator is powered by diesel or gas fuel and could provide temporary electrical power. Portable generators can be of many types and here are few:

#Portable Construction and Industrial Generators:

These portable construction and industrial generators are the ideal choices for the job site and various industrial applications. High cycle generators offer 60 Hz power for standard tools and 180Hz power for high-cycle vibrators

#Portable Residential Generators

It is a perfect choice to power essential items in your home when the power goes out and for use around your yard. Most residential portable generators run on gasoline. However, some models run on L.P., Natural Gas, or all three.

#Portable RV/Recreational Generators

The inverter technology makes them super quiet for recreational use and also provides the cleanest power for sensitive electronics like computers. These generators run on gasoline.

#Properties of Portable Generators

  • Uses a governor to control the engine’s speed
  • Can power tools and lights
  • The engine should run at 3600 rpm to render the standard 60 HZ of current
  • Has enough power to run a freezer and television
  • Can be used in remote sites
  • Can be wired into a facility’s sub panels
  • Can plug into electrical appliances or tools via its sockets
  • Uses a combustion engine to conduct electricity.

#Inverter Generator

An inverter generator generally uses an engine that is connected to an alternator to produce AC power. This generator also uses a rectifier unlike other generators to convert the AC power into DC power.

#Properties of Inverter generator includes

  • Can easily fit into a car, RV or boat.
  • Tends to be little and lightweight.
  • Its AC can be kept to any voltage and frequency when used with proper equipment.
  • More energy-efficient, as the speed of the engine, could be varied depending on the required power.
  • Maintains a constant flowing of current to an appliance.
  • Outputs AC current, convert it to DC current and finally invert it to AC.
  • Undergoes three phases to produce electricity.
  • Uses advanced electronic circuitry.
  • Relies on high-tech magnets.

#Standby generator

A standby generator is a type of generator that works with an automatic transfer switch which commands it to power any device up during power loss.

#Properties of Standby generator includes

  • Used in some safety systems for elevators, standby lighting, medical and life support equipment and fire protection systems.
  • Is constantly monitoring utility power.
  • Undergoes weekly self-tests to check whether it is properly reacting to a loss of power or not.
  • Senses the power loss within seconds and boots up electricity so that power loss is felt very briefly.
  • Uses an internal combustion engine.
  • Will run on the fuel type that is already in use in the facility or home.
  • Could operate on natural gas or liquid propane.
  • Has 2 components: a standby generator and an automatic transfer switch.
  • Delivers permanent power protection.
  • Operates automatically.

  • A standby generator is used for emergency settings and hospital machinery.


Applications of Portable Generators

Portable electric generators are very useful and helpful to have in times of emergency and for planned-out uses as well. Portable generators are more powerful and inexpensive as ever. Best of all, the investment made on this generators could be useful for various purposes at home, off the grid, or for other particular uses.

Here are the few best uses of portable generators:

#Outdoor Events

Portable generators are not only used for emergencies. Many people and venues purchase and use these portable generators to power recreational and outdoor events. There are not always structures available to draw power from, so when having outdoor events such as reunions, campsites off the grid, festivals, large family or outdoor event, or barbecues, the use of these generators are very important  to power up lights for beautiful illumination at parties, power fans to keep the people and things cool, plug in speakers for music, and other uses.


Though this may sound little surprising, the electric generators are highly popular and useful for emergency farm use also. During storms or any other disasters that bring down the power, farms may come to a stand-still. While gas-powered machinery may still work, lighting and providing electrical help to the farms.

#For a Perfect Trip

Whether you go on a small road trip or a camping trip, having a portable generator along with you lets you take all modern conveniences along with you. Generally, camping sites permit generators that are quiet to power portable freezers, radio, television, and lights. Though you can go on such trips with any power, they are going to leave you and your companions groping in the dark once your campfire burns out.

#Power Outages

Some people purchase electric generators solely for the use as an occasional power outage that occurs when a car hits a transformer, or a storm has become particularly bad. Mainly, due to a large amount of elderly in our country, many households have power-dependent medical items such as oxygen-producing machines and scooters that run on electric charges. When the current goes out, you never know how long it will take to come back on, so the occasional user often buys electric generators for small-scale usage as they know it will keep the essentials running until the grid is up and running again.

#Construction Sites

Construction sites rely more on electric generators to use their industrial lighting, use their nail guns, spray guns for painting, and as an outlet for their power tools. 

#Natural Disasters and Emergencies

This is one of the important reasons for use of generators in the country, due to valid concerns over earthquakes, tsunamis, hurricanes, tornadoes, and other disasters that are common in certain areas of the country. While it comes to natural disasters, there is much chaos, and it takes more time for help to arrive. So until then, using an electric generator allows you to be taken care of yourself.



A portable generator would be the fastest way to whirl back into action if you are facing a sudden power cut in your place but want to use your computer for work today. Differing from permanently fixed standby generator, these portable backup generator unit needs less bucks up front — about $500 to $2,500. Best of all, it is also very easy to get up and to run. You can purchase the best portable generator for a home online, or at a local equipment dealer, or at any big store. Then simply drive it home and store it in the garage or shed.
