Vital Guide to Find the Best Portable Generator in 10 Steps

Portable generators can serve as emergency power backup options in homes, or as the primary source of electricity off grid such as on a construction site, on your camping trip or in your RV. Generators history go a long way. Today, with such a wide range of options when it comes to these portable engines, finding the right generator for your specific needs and budget is not an easy task. Below, we have outlined the things that will help you in picking the right portable generator for your home, or off-the-grid power needs. They include:

  1. Power Requirements

electricity lights

How, and where you intend to use your portable generator determines the power rating of the generator that you should get. The power requirement in a home is different to the power requirements in a camping day or on a construction site, and for each of these situations, you will need generators of different ratings. The amount of power that you need is influenced primarily by the items that you intend to power up.

Appliances are usually rated in their starting, and running wattage. Starting watts are the amount of power required to start-up an appliance, and power consumption is usually highest at this point. The running watts are the amount of power needed to run the appliance continuously. The starting wattage rating is several times larger than the running wattage, and this may mislead you on the amount of power that you require from your portable generator.

As you estimate the amount of power that you will need, factor in all the applications that you intend to power up, and pick a generator that is rated slightly higher than that figure. The extra allowance caters for additional power needs that may arise in the future.

  1. Quiet Operation

Generators that run too loudly can cause hearing damage, and act as a nuisance to your neighbors. You should, therefore, buy a portable generator that runs as quietly as possible, or purchase long cables to be able to set your generator few meters away. The acceptable noise level for generators is 60 decibels and less. At this level, you can comfortably hold a conversation and act less as a disturbance to your neighbors at home, in your business premises or at the camp site. Some examples of noise operation measured in decibel:

  • Whisper talking – 30 dB.
  • Operating refrigerator – 50 dB.
  • Vacuum cleaner – 70 dB.
  • Blender – 80 dB.

Professional generators for factories are a little bit louder because of their high power rating. Professionals using these machines are advised to wear the right protective gear, to safeguard their health and well-being.

  1. Fuel Economy

Efficient fuel consumption is a feature of a good portable generator. Such generators, adjust the rate at which they consume fuel with the applied load. With this setting, the engine runs in full-throttle only when the applied load equals the generator’s maximum rating. Such as Honda generators that use an Eco-Throttle feature, that ensures that the engine consumes fuel efficiently in line with the applied load. Efficient fuel consumption helps you to save money on fuel expenditure.

  1. Run-Time of a Fuel Tank

Generators usually indicate their run time at either quarter (25%), or half (50%) of the load. This represents how long it will run on a full tank of fuel at the set percentage of its total power. If you intend to use the generator for emergencies, and you cannot estimate how long the main power supply will be out, then you should get a generator with a large tank.

  1. Ease of Use

The best rated generator that you can pick is easy to use, and features automatic control options that protect the generator from damage. Low-oil shutdown feature which turns the engine off when the level of oil gets too low. A fuel gauge to easily check the remaining run time. An electric start is another of such features; with an electric ignition, you simply push a button to start the engine. The pull cord method of starting generators is outdated and tiring. However, a good generator has a pull cord as a backup starting option.

  1. Ease of Movement

The weight of a generator is not necessarily tied to the amount of power it generates, but high power generators are usually a bit heavier. The presence of wheels and handles makes it easy to move these engines around. Professional generators are a bit heavier since they pack up more components, and a larger fuel tank to be able to generate all that power that you need for your various power tools and equipment.

  1. Number of Outlets

A generator with several outlets allows you to optimally use your generator by spreading its load. However, using all the outlets on your generator is not advisable as it ‘strains’ the generator, and this puts its longevity in jeopardy. We recommend using all the outlets only in emergency situations, or when the appliances that you are using are low-wattage.

  1. Emissions

Generators that run on fossil fuels are the biggest culprits when it comes to emissions. This includes diesel and gasoline generators. If you are looking for a ‘green’ generator then a solar generator or those that run on propane may be ideal for you. Also look for the exhaust certificates that the generator could obtain, such as EPA, CSA, or CARB.

  1. Budget

The price of a portable generator is influenced by:

  • The amount of power it generates.
  • The ease of use features it has.
  • Its noise rating.
  • The brand manufacturer.

Generators from established brands such as Honda and Yamaha are somehow pricey, but for a good reason. These manufacturers are experienced in making these engines, and you can be sure that their generators are reliable enough to serve you for a very long time.

  1. Warranty and Customer Service

Generators are pricey machines, that could set you back a couple of thousands of dollars if they get damaged. It is for this reason that you should only buy a generator that is backed by a long-term warranty from the manufacturer. This way, you can have your generator repaired, or replaced in the event of a failure. A long warranty also shows the manufacturer’s trust in their product. A good warranty is two, or three years long. Read the warranty information carefully to know what is covered, and what isn’t. And, keep in mind to never accept damaged goods.

How Much Power Do I Need?

Portable generators are convenient power sources that are used as primary, and backup power options in various situations. You can use a portable generator as:

  1. A backup source of power for your home or business establishment.
  2. For recreational activities as a primary source of power for tailgating, camping, and RVing.
  3. To power up tools in a job, farm or a construction site.

The amount of power that you need in each of these situations depends on various factors, key among the equipment, tools, and appliances that you intend to power up with the portable generator. Here is how to decide about the amount of power that you require in each of these situations.

  • Home Backup Power

wall outlet

The amount of power that you need in your home depends on the electric appliances, and systems that you have installed in your home. You also need to decide which appliances will be running simultaneously in case of a power outage. This will help you determine the size of the portable generator that you should get for your home emergency backup.

If you are using a pump to draw water from a well for home use, and you’d still want to operate it when the main grid power fails, then you will require a powerful generator that is capable of running the pump and other appliances in your home. A well pump may require more than 3800W of power for successful operation. You, therefore, require a generator rated 5000W and above to be able to use the pump, and power other appliances in your home.

Other household appliances that require significant amounts of power to operate include:

  • A small furnace that consumes about 3000W of power.
  • A pressure washing machine rated at 3600W.
  • Electric heaters rated 4500W and above.
  • An electric clothes dryer rated at 5400W.

Portable emergency generators come in different power ratings with the most common in the range of 3000 – 5000 watts. With this amount of power, you can simultaneously run several appliances such as your AC, TV, and kitchen appliances.

  • Recreational Power Requirements

Thanks to portable generators, campers and RVers alike enjoy similar power supply benefits to those who are connected to the grid; such as being able to use their mobile devices to remain in touch with friends, and family. They are able to use various kitchen appliances to prepare meals and to cool down the place with an air conditioner.

  1. Camping Power Requirements

Items that most campers take with them to camp include a digital camera, coffee pot, and a set of lights. They will also need to charge their phones, and maybe laptops. For a small camping trip, you will probably need to power the lights and to charge your phone and laptop. In this case, a small generator rated 1000W or less will do. Heavy campers, with a lot of equipment that require heavier power supply, would require a generator with a higher power rating in the region of 1000W – 2000W.

Here is how much power some of these items consume in operation:

  • Coffee maker – 600W.
  • A Blender – 300W.
  • Laptop charger – 200W.
  • Light bulbs – 100W.

As you camp, you will, therefore, require power in the range of 1000 – 2000 watts.

  1. RV Power Requirements

A portable generator also comes in handy in powering up the different appliances in your motor home. The appliances that you have in your RV consume a lot of power than those that you will find with an average camper. This is due to the presence of heavy-duty appliances such as an air conditioner, a fridge, and other kitchen appliances such as a microwave, and an electric kettle. The AC, which ranks as the highest power consuming appliance in most RVs, can run on 2000W of power but requires about 3000W to start-up. To power up all these appliances you will require a portable generator rated 3500 watts and above.

If you have a larger AC, the best option would be to connect two smaller generators than using one large generator. It’s easier to move two small generators than it is to move a large one. You can learn more about some of the most important efficent items for an RV here.

  • Job Site Power Requirements

Construction and other power tools require a lot of power to be able to function properly. A typical 10 inch saw, for example, requires 4500W starting power, and eventually stabilizes at 1800W running power. The running power increases as you increase the load (cutting through thick timber). You, therefore, require a powerful generator to keep the saw running as well as other power tools such as drills, and grinders.

To effectively meet the power requirements at a job site, you will need a generator rated 7500 watts and above.

How to Determine the Power Requirements of a Specific Appliance?

Typical locations where you can find the power rating of an appliance include:

  • The product stamp at the bottom of the appliance.
  • Its name tag.
  • The data tag found on motors.

Most appliances indicate their power requirements in amps. Determining the appliance’s power requirement in watts can be challenging if you are not familiar with how to perform the conversions. Here is how to convert the power ratings from amps to watts:

  • Watts = Volts x Amps

Most appliances run on 120 volts. There are those that run on 240 volts, and those that can run on either of these voltages. This simple multiplication will help you to figure out the power rating in watts of an appliance.

Types of Generators and their Properties

There are different types of generators to choose from for your power needs. Each of the different types is unique in its mode of operation, build, and the type of fuel it requires for operation. Understanding the different types of generators, and how they function will help you in your quest to find the best portable generator for your specific power needs. Here are the different types of generators, showing you a side of their pros, and cons:

  • Gas-Powered Generators

gasoline fuel

Gas-powered generators are the most common type of generators around. They run on gasoline which is relatively cheaper than other types of fuel. Gasoline is readily available as well as this makes owning a gas-powered generator very convenient. They are safe to use, and they come in smaller sizes, and models making them quite portable.

They are, however, not environmentally friendly as they usually produce high emissions when in operation. Gasoline has a shorter lifespan of less than a year and, therefore, storage becomes a challenge. Gasoline generators are not ideal for use in colder environments as they do not start well in such weather.

  • Diesel-Powered Generators

diesel fuel

Of all the fuels that can be used on a generator, diesel is the least flammable. Diesel is just as available as gasoline, and this makes for added convenience. These generators are among the most fuel-efficient generators around. They are powerful machines that last longer under rigorous use, provided they are maintained properly. They generate a lot of power, and if you have some heavy-duty tools to power up, then you are better off with a diesel generator. Diesel has a shelf life of about 24 months, much more than that of gasoline.

They are easy to maintain, but when it comes to pricing, they are slightly expensive than gas-powered generators. The emissions of such engines are also prohibitively high, and it is advisable to limit the amount of time you run these generators in a day for environmental protection.

  • Propane-Powered Generators

propane fuel

Propane generators are clean-running engines that run quietly than other types of generators. They are fuel-efficient machines that ensure economy in fuel consumption. Propane is readily available, and it boasts a better shelf life than diesel or gasoline fuels. They are quite affordable when compared to diesel, and gas generators. They are durable machines as well that can serve you for a long time.

Propane generators are ideal for small appliances, or as a backup power option in the event of a power outage. They are not ideal for large power operations as the logistics required to install, and store them are quite prohibitive. Propane is highly flammable, and potentially explosive since it is usually kept under high pressure. The fuel systems of these generators are very complex and, therefore, they are subject to frequent failures.

  • Solar-Powered Generators

solar fuel

Solar generators trap the sun’s energy using solar panels, convert it into electrical energy, and store it in a battery bank for later use. They produce clean free energy, and the fact that solar energy is a renewable resource means that you will hardly run out of ‘juice’ for your generator. Solar generators have no moving parts, and this makes maintaining them very easy. They can be used outdoor as well as indoor areas since they have no fumes or emissions.

The amount of power produced by solar generators is relatively low when compared to other types of generators. They are not ideal for powering up heavy-duty, or large appliances; unless you have a big area available to mount a lot of solar panels in it.

  • Inverter Generators

Conventional generators are usually characterized by power surges that are particularly harmful to sensitive electronics. Inverter generators on the other hand incorporate built-in inverters, that convert the direct current into a smooth sine wave power by limiting their total harmonic distortion; making them safe to use with delicate appliances and electronics.

Top 10 Most Useful Portable Generator Accessories

Portable generator accessories are essential components that ensure that your generator is functioning properly. Without these components, the operation of your generator gets crippled, and this leaves you without emergency backup power for your home, construction site or the primary power supply for your RV. Here are 10 of the most used portable generator accessories that you will definitely need at some point, to use your generator optimally.

  1. Transfer Switch

transfer switch

This is an electrical switch that transfers the load between the generator, and the main utility power in the event of a power outage. Usually connected to the electrical panel in your home or RV; and when the main power fails, the portable generator carries the load and upon resumption of the main utility, it transfers the load back to the main supply.

Transfer switches are of two types:

  • Manual Transfer Switch

It functions manually. You physically have to flip a switch when there is a power outage to transfer the load to the generator, and when normal power resumes, you have to put the switch off as well.

  • Automatic Transfer Switch

It automatically transfers the load to either the mains, or generator power supply as needed. It can be programmed to carry specific loads depending on your immediate power needs, and the size of the generator.

We’d recommend having a professional install the transfer switch for you. This way you can be sure that the connections are correct, and you avoid any fatalities that may arise as a result of poor connections.

  1. Extension Cords

Extension cords ensure proper delivery of electricity from the portable generator. You, therefore, require some heavy-duty extension cords to connect the various appliances that you intend to power up with the generator. Power cords are rated in amps, and the power cord that you buy should correspond to amp specification of your generator’s outlet. The cord should be of suitable length for added convenience.

  1. A Muffler for Quiet Operation

Most generators have mufflers installed to make them work as quietly as possible, but sometimes this is not enough. Especially at noise enforced campsites, understanding noise-level is important. To reduce the noise further, you can invest in a muffler and install it on your generator. Pick a muffler that fits your generator for the best noise reduction capability.

  1. Automatic Voltage Regulator (AVR)

This is particularly important if you have sensitive appliances to power up. An AVR maintains the generator’s voltage at a stable state for effective usage with delicate electronics.

  1. Fuel Stabilizer

A fuel stabilizer is particularly important if you intend to store your portable generator for some time with oil in it. It keeps the fuel fresh and prevents gum buildup. This way you don’t have to drain the fuel before storage.

  1. Maintenance Kit

Just like any other engine with moving parts and components, your portable generator requires regular maintenance for it to function optimally. A good maintenance kit is a perfect solution to keep your generator in top condition. Such a kit usually contains:

  • Several air filters to replace old dirty ones. This ensures proper air circulation for optimal generator operation.
  • Spark plugs in a generator wear out with time. A maintenance kit contains new spark plugs to replace old ones.
  • The oil in the maintenance kit is for replacing the used-up oil.
  1. Cold Weather Kit

If you live in an area with cold weather, then you ought to have a cold weather kit. This kit includes an oil heater, and a battery warmer. A battery warmer, placed below the generator’s battery to heat it up when the temperature gets too low. The oil heater is in the form of a crankcase heater, that heats the oil to prevent it from solidifying.

  1. Wheels Kit

Wheels are great accessories for your generator. If your generator lacks wheels and is heavy, then you’ll need to fix a wheel kit to make it portable. Non-flat wheels are the best as they are easy to maintain.

  1. Generator Cover

A generator could get damaged when it is left exposed without a proper cover. Always cover the generator with a suitable cover to protect it from the elements when it is not in use. A good generator cover is weatherproof, and this ensures that the generator is forever dry and free of dirt, dust, and rust. Make sure that the cover you acquire matches the size of your generator for proper protection.

  1. A Remote Start

Sometimes you want the convenience of being able to run your generator without having to physically walk to its location. In this case, you need a remote start. A remote start allows you to initiate the generator from the comfort of your seat with the push of a button. A remote start comes as a wireless remote or a remote connected by a long cable from the generator.

Simple Steps to Ensure Generator’s Safe Use and Long Life

A generator comes in handy when the mains supply goes off or when you are off-grid, and you still require power for your appliances and equipment. Proper usage of these machines is essential if you are to make the most of your generator. Failure to do so can prove hazardous to you, those around you, and the machine itself. Here are tips on how to use a generator safely to ensure its long life.

  • The Best Location for Your Generator

Where you place the generator as you operate it is just as important as how you use it. The best location for your generator should be:

  1. Dry and Away from Rain

Water is one of a generator’s worst enemies. Operating a generator on a wet surface, in the rain, or any other wet conditions puts you at risk of electrocution. Other than ensuring that the surface is dry, you should never touch a generator if your hands are wet.

  1. Open and Well Ventilated

Carbon monoxide (CO) is one of the products of burning fossil fuels to generate power. Carbon monoxide is very toxic, and if your generator runs on fossil fuels, then you are at risk of carbon monoxide poisoning if you do not channel the exhaust properly. It is for this reason that you should ensure that your generator is always positioned in an open place with lots of fresh flowing air. Never use a generator indoors, and make sure that you do not direct the exhaust to any nearby windows, or to your neighbor’s premises or RV.

  1. Steady and Stable Level

This prevents the generator from falling off in operation. A fall may damage the generator and/or the applications it is powering.

  • Proper Connection and Wiring

Proper connection and wiring ensure proper delivery of power from the generator to your home, recreational vehicle, farm, or construction tools. To use a generator for your motor-home, you should make sure that you have a transfer switch installed by the electric panel for an effective changeover. A transfer switch transfers the load from the mains supply to the generator power, and vice versa as required. It’s advisable to have a professional install this device for you if you are not familiar with electrical installations.

Without a transfer switch, you may be tempted to plug the generator directly into one of the power points in your home or RV. This is very dangerous, and it back feeds power into the power lines. This may electrocute any service men who may be performing repairs on the line, and damage the generator as well.

If you intend to tap power from the generator for your appliances, then you should use a heavy-duty extension cord built for outdoor use. The rating of the cord should equal the power output of the generator. Make sure the cord is not cut or exposed in any way.

  • Fueling the Generator

Only use the type of fuel that is recommended by the manufacturer. Failure to do so may result in extensive damage to the generator, and you void the warranty for generator damage. Before fueling the generator, make sure that it is turned off, and it has cooled down. Fueling a generator when it is hot may cause a fire as the hot parts may ignite the fuel.

  • Storage and Safe Keeping

When you are not using your generator, store it in a cool, and dry place. It is advisable to drain the fuel before storage but if that is not the case, add a fuel stabilizer to prevent gum buildup.
