Portable Generators Buyer’s Guide

A portable generator can supply power to important devices around the home in the face of a blackout. When outside the home, this type of small generator can provide power for lights, power tools, small appliances, TVs, and other types of electronics when camping. Larger models can also be used at construction sites in order to operate power tools including air compressors, paint sprayers, saws, and drills. A model that is highly portable can come in handy for a wide variety of uses. Before I discuss the important features to look for, first I’ll go over the many benefits that come with purchasing a portable generator for home or work use.

Benefits of Portable Generators

Nothing can be more frustrating than losing power when you need it the most. Unfortunately, inclement weather during the summer, fall, and winter months can lead to blackouts. Having a portable generator as a backup can help you and your family stay connected to important electronic devices until the power is restored. Below, I’ll go over some of the most important benefits these portable models have to offer.

  • The highly portable design is the first benefit.  These models are durable and made to last. Equipped with never flat tires and a basic design, these models can be taken just about anywhere.
  • They will help to keep the heat running in the winter, the air conditioning going in the summer, and they can power the lights during a blackout.
  • Models that are used in commercial operations, come equipped with a few characteristics that make them more flexible than a standard generator, which is why they’re often used in a variety of operations or businesses.
  • Additionally, they can be relied upon at work sites for construction jobs when a power outlet is not available.
  • These generators come equipped with a number of safety features including circuit breaker protection, automatic shut-off, inverter technology, and spark arrestors.
  • With a generator, you won’t have to worry about the power going out which would normally cause a business to close early or could be a major inconvenience for home life. If there are critical applications that need to be performed on the job site, then a portable generator can provide the power you need.
  • These types of generators are also perfect for disaster recovery efforts. After a natural disaster strikes, a portable model can be dispatched to provide aid and relief.

As you can see, there are many benefits that come with owning a portable generator, whether it’s for home or work purposes. The key will be finding a model that offers a sufficient amount of power for your home or work site.

Important Features

There are many important factors to consider before you buy a generator. Ask yourself the following questions before you buy:

  • What do I need the generator for?
  • Do I need a model that can handle daily use?
  • Is the generator powerful enough to restore power to my home?
  • How many devices is the generator able to power?
  • What are my power needs?

The answers to these questions can help you narrow down your choices and purchase a model that comes loaded with the right type of power based on application, the size of your home, and where and how you plan to use the generator.

Portable Generator Types

For a portable model, you’ll find it much easier to find a generator designed to serve your specific needs. These generators are available in five style options including:

  • Professional
  • Semi-pro
  • Emergency
  • Recreational
  • Solar


This type will power your stuff but it’s also able to power itself as well. Solar powered models are a great choice and they’re in high demand for their portable power increase and renewable energy. With this style option you will not have to deal with gas, fumes, or loud noise. This is what makes this type of generator perfect for areas without primary power sources or camping. Additionally, this type of generator is also safe to use for sensitive electronics. As solar power technology improves over the years it’s quickly closing the gap between other portable power options.


This type of generator is also referred to as a camping generator. Usually, when someone thinks of a camping generator they may think of the louder models. However thanks to new inverter generator technology these models are basically the modern replacements of camping generators of the past.

Using state-of-the-art technology, these generators are now very quiet running and are perfect for camping, tailgating, and RV use.


These generators are perfect for camping or tailgating. However they are not a great option for a power outage at home. Smaller models will only be able to power one or two appliances. Additionally, lower priced models will come equipped with very small gas tanks that must be refilled every 2 to 3 hours. Basically, these generators are not very powerful and they cost a lot to run. However, there are many models that come equipped with more powerful larger engines that are designed to restore power to certain mission-critical appliances such as sump pumps, fridges, breathing machines, and lights. Additionally, higher priced models often come with larger gas tanks that are designed to run for several hours without interruption. While they’re not considered professional grade, they’re comparably durable.


For homeowners these generators are the most popular choice. Aside from their durable components and a high-quality engine, this type of generator is capable of restoring power to a home in the event of a blackout. They’re also a great choice for construction jobs.

While they’re not equipped with many of the same bells and whistles that you’ll find on professional models, they are easily classified as heavy duty.


The style of generator can be used for tailgating, blackout use and construction sites. These heavy-duty models are built in limited quantities for professionals who are willing to spend the money on these powerful reliable generators. This type of generator is made with commercial quality components and they’re designed for daily use.

Generator Sizing

In order to size a generator properly, you’ll need to determine the wattage of each of the appliances that you want to power at once. Whether you have recreational use in mind, looking to run one at a job site, or you need a generator for emergency power, there is a lot to consider when you’re shopping for this style of generator. But by far, the most important thing you need to know is how much power you need. A fridge can only need 600 watts to run, but what  if it needs a total of 2000 watts of startup power? Learning about an appliance’s power needs is simple enough. You can read the appliance’s user manual to look for this information or you can search online. This should be done for every appliance or device that you plan on using with the generator.


Another factor to consider is what type of outlets are needed. A small inverter generator will come with one 220 volt AC Outlets. Some models may also come with a couple of USB ports. Once you reach 400 watts, you’ll notice 240-volt plugs show up along with more 120-volt outlets. You’ll need a 240 volt plug if you’re considering having an electrician wire the generator directly into your panel. Since the generator will be used outdoors, you’ll need to look for one that comes with GFCI protected Outlet


Generally, you’ll need a THD, or total harmonic distortion that’s less than 6% in order to avoid damaging sensitive electronics.  Usually referred to as pure sine wave or clean power, it’s a more predictable and stable level of voltage. Pure sine wave models are often pricier and can be found on lower watt models.

Frequency of Use

Many models will come with a warranty that will cover the appliance for several years. For recreational use or emergency power, many major brands produce models that will work for you. However, if you’re using this model for work purposes on a daily basis then you’ll need to get a generator that is equipped with a commercial engine. Well this type of generator will be a better fit it will also come with a warranty that will cover the appliance for more than four years, as opposed to recreational generators that only have a warranty that will cover it for a period of three to six months.


The most common type of generator runs on gas. However, during the days following a major storm, fuel can be hard to come by.

Diesel generators often provide better fuel efficiency for consumers who are willing to pay for the upgrade. Additionally, you’ll lose the carb that always seems to be clogged at the least convenient moment. If you’re looking into a model designed for whole house use then you’ll be looking at models that run on diesel. Just keep in mind that diesel can be very hard to find in times of emergency.

Propane generators are another option. If you want to use a fuel that’s more environmentally friendly and you don’t mind that it’s more difficult to use, then this type of generator is a great option.

Battery powered models have the advantage of being recharged using solar energy. They have no emissions and run silently. The biggest downside is the initial cost and the lengthy recharge time. Essentially, outside of tailgating and camping they’re not very practical to use.

Fuel Tank Size

If you want to run a generator for several hours, then you need to look for a model with a larger fuel tank. Most models have a fuel tank that can allow you to run it for a period of six to eight hours using a 50% load. If you use a lower percentage of the available power you’ll be able to run it for a longer period of time. However, if you’re given the choice between choosing a smaller or larger tank, always go with the larger.


Electric start engines are much easier to use than pulling a recoil cord. When you’re shopping for a portable model, you’ll find most still rely on lead acid batteries just like a car. However, there are some lithium-ion ones currently on the market.

Always make sure that you charge the battery before use. Most models will be fine leaving the charger unplugged in order to maintain the charge between uses.


Small models are often much quieter than large, high-powered generators. If you’re camping or tailgating your neighbors will definitely appreciate a generator that’s quiet running.

However, if you’re looking at higher powered generators that offer around 4000 watts or more, then you’ll have a very difficult time finding a quiet running generator.

Electronic Fuel Injection

This is a great feature to have because it eliminates the need for a carb, which will make maintaining a generator much easier, since you’ll no longer have to worry about a clogged carburetor. Another bonus is that you won’t have to deal with any issues starting up the generator in cold weather.

Carbon Monoxide Detection

There are many manufacturers that now produce models with carbon monoxide detection. This type of detector will measure the levels of carbon monoxide near the engine, shutting it down if the levels get too high. This type of detector will usually work faster than the ones that are installed in homes and will do a much more efficient job of preventing carbon monoxide poisoning. However, this type of detector can also be very sensitive. Be sure that the generator’s exhaust is pointed downwind from the sensor. To avoid a false reading, you must also avoid placing the generator in a corner.

Wheel Kits

There’s no doubt that generators are heavy and not all will come equipped with wheels. Some models require you to purchase a wheel kit separately so be sure to take this extra cost into account before you hit that buy now button.

Using some basic tools. The entire process takes just a few minutes.

Lift Hook Bar

For work or commercial use, there’s a good chance that you’ll end up needing to lift the generator to a higher level at some point. Models that come with a lift hook bar will give you a big advantage and can also save you plenty of time and back-breaking work.

Home Use & Connecting a Generator

Having a generator connected directly to your house is a very easy way to ensure you have power in the event of an emergency power outage. The best way to go about this is to purchase a generator that’s designed for this purpose and one that will turn on or off automatically once it detects a power outage. However, this style is more expensive than a portable generator. Fortunately, you can also connect a portable generator to your home. But doing so is not a DIY job. This is because a transfer switch will need to be installed. This job should be done by a qualified electrician only. Additionally, there are other factors to take into consideration as well. The first is making sure the generator you purchase offers enough power. If the generator isn’t powerful enough to run your entire home plus the power needed for startup, then you’ll have to flip some breakers in order to prioritize. If you plan on using a portable generator, then you’ll need to ensure that you know where it’s going to be placed while it’s running and that you have a cable that’s long enough to reach the transfer switch.

Safety Tips for Portable Generator Use

Before you take a look at these usage tips make sure that you read the included owner’s manual that comes with your portable generator. It’s very important that you follow all the instructions carefully in order to safely operate and start the generator. When it comes to safety, never cut corners. The tips I’ve included here are not intended to substitute the directions in the owner’s manual for your specific model.

  • A generator’s exhaust contains carbon monoxide which is a deadly poisonous gas that cannot be smelled or seen. Avoid running a generator indoors or even in a partially enclosed area such as a garage. The generator should only be used outside, far away from crawl spaces, vents, doors, and windows. It should only be placed where there is adequate ventilation. Opening windows and doors or using a fan will not provide sufficient ventilation.
  • If your generator does not have a built-in carbon monoxide detector, I recommend installing carbon monoxide alarms in the home.
  • Most people already know how extremely explosive gasoline is. Avoid overfilling the fuel tank on your generation and make sure to leave enough room to allow the fuel to expand. If you accidentally overfill the tank, the fuel can overflow onto the hot engine, causing an explosion or fire.
  • Avoid adding fuel while the generator is hot or running. Generators need time to cool down completely before fuel is added.
  • A generator should never be stored with fuel left in the tank where gas vapors can reach an open flame, pilot light, or spark.
  • Never smoke near a generator or fuel.
  • Most generator parts can get hot enough that they will burn the user during operation and even during the cooling off process once it’s been shut off. Avoid coming into contact with the generator until it is cooled down completely.
  • Connecting an electric powered portable generator directly to the wiring in your house can be deadly. Generators that are directly connected to a home’s wiring can backfeed onto power lines, injuring utility workers or neighbors.
  • Avoid connecting a generator into a regular household outlet or directly to your home’s wiring.
  • Only stop or start the generator when there are no electric loads connected.
  • Overloading a generator can damage electronics and valuable appliances. Avoid operating more equipment or appliances than the output rating on the generator. Only use this type of generator when necessary and to power essential devices.
  • You the correct power rated power cords. For individual appliances, plug them into the generator using outdoor-rated heavy duty cords that have a wire gauge that’s adequate for the appliance load. A cord that overloads can cause equipment damage or fires. Avoid using extension cords with worn shielding or exposed wires.
  • Never operate a generator in wet conditions including snow and rain.
  • Generators must be grounded properly. If it’s not grounded properly then you’ll risk electrocution.
  • Always allow for a minimum of four feet of clearance on each side of the generator when it’s in use.
  • Generators can be used in a variety of temperatures, but they should be well protected from exposure to the elements.
  • The generator should only be operated on a level surface where it will not be exposed to corrosive vapors, dust, dirt, or excessive moisture.
  • Regularly inspect your generator and contact a local authorized dealer for replacement, repairs or replacement parts.
  • When setting up, adjusting, making repairs, or transporting, make sure that you always disconnect the spark plug wire so that it is unable to contact the spark plug. Doing so will prevent accidental startup.
