Terms used in the below table along with their meanings:

  • G stands for Gasoline
  • P stands for Propane

Starting Watts: The maximum watts a generator can produce are known as starting watts. Starting wattage is also known as peak wattage. They are needed to start motor-driven products like a refrigerator, circular, saw, and air conditioner. Once the appliances are started, the starting watts are no longer needed for that particular appliance and can be used for starting other machines/tools/appliances.

Running Watts: The average output of your generator is known as running wattage. They are needed to keep your appliances running. Running watts are also known as rated watts. Running watts are always less than starting watts.

Runtime @ 50% Load (Hours): It defines how much time a full gas tank or a propane cylinder will run with a half load on the generator.

Buyer’s Guide

Output Power

To find out your exact power needs, make a list of all the appliances you plan to run during a power outage or in your RV. Mention the starting and running wattages and then count the total for both. Consider the example below.

Appliances Starting Wattage Running Wattage
Refrigerator 1400 300
1/2 HP Furnace 2350 875
TV 400 400
Lights 300 300
AC 1800 1200
Total 6250 3075

The total starting wattage of all the appliances is 6250 watts, and 3075 is the power needed to keep them running. In this case, a generator with a 3500-watt starting power will be perfect. The trick is to add appliances one by one on your generator. It is better to leave a cushion of 300-400 watts. You can calculate the wattage of your appliances in the same way.

Conventional or Inverter Generator

traditional generator characteristics

The inverter generator can get clean AC power, but you have to go with a conventional unit to get higher output power. Inverter machines are more fuel-efficient and are compact and light in weight. On the other hand, conventional units have big fuel tanks and big bodies.


The first thing to look at when buying a portable generator is how portable your generator is. If it is lightweight, then you may only need a comfortable handle to carry it. On the other hand, make sure your unit has big wheels and a durable handle if it is heavy.

Fuel Type

It is always suggested to go for a dual fuel portable generator. The reason is that when any fuel gets short in your area due to any reason, you can still manage to run your generator on the second fuel option.

As you can take portable generators to any place, dual fuel generators are the best choice for traveling.

Fuel Efficiency and Runtime

Your portable generator must be fuel-efficient to give you extended runtime. During outdoor trips and natural disasters, fuel-efficient generators come in handy. A generator with a big fuel tank and a fuel-efficient engine will benefit you a lot.

Gas Tank

Large generators come with a big gas tank. If you use your generator frequently, then look for a big tank. Otherwise, a small tank will suffice. Apart from the gas tank, it is also essential to consider the run time.

Control Panel

user friendly control panel

A user-friendly machine will give you full features on the control panel. It will come with a digital display to tell you about the total working hours, oil level, wattage being drawn from the unit, and other working parameters.

Starting Mechanism

If you don’t want to pull the starting rope every time the power goes out, look for an electronic starting generator. Some generators also come with remote control start feature. All such features make our life comfortable in one way or another. An electric start generator is costly as compared to a recoil start. The ideal situation is to look for a generator that offers both starting mechanisms.


Your machine must be both EPA and CARB compliant to move with your generator in all the states of America.

Output Power

What is your purpose for buying a portable generator? The answer to this will help you to determine the total power you need. If you need a portable generator for your home or construction site, then a 5,000-watt to 10,000-watt generator would suit you. If you require an RV generator, then a 5000-watt generator is ideal. Or if you need to power your campsites or tailgates, then 2000-watt generators are best suited.

Paralleling Capabilities

You may need more power sometimes. Hence, a generator with a paralleling ability is best under such situations. It is easy to connect two inverters. However, connecting a conventional generator is not always possible. You will have to install a paralleling kit and then connect two generators. Even if it works, you may experience fluctuations in the output.

Noise Level

If you are conscious about your generator’s running sound, buy an inverter as it is quieter than a conventional generator. However, its power output is less than a conventional generator, but it is best to run your sensitive appliances. Conventional generators are loud, but they can be made quieter with a generator box and some other tricks.

Warranty and Customer Service

A generator with a warranty is always better than one without a warranty. A new generator may start troubling you after a year or two. We don’t want you to spend a hefty amount on repairing it. Therefore it is better to look for a generator with a warranty cover. Make sure you read all the terms and conditions. Helpful customer service is a cherry on the top as far as the after-sale service is concerned.


Inverters are costly compared to conventional generators. The price you have to pay for a generator depends on the features. Models with advanced control panels, electric starting, dual fuel options, and safety features are expensive than simple generators.

Fuel Type: Gas vs. Propane

Selecting the right fuel type is very important. Before you start using your generator, it is best to know about some of both fuels’ basic properties. These properties are related to the generator and help you get more out of it in the long run.

Power Output: When you compare gas and propane in terms of power output, the gasoline takes a clear lead. The reason is gas has a better energy density as compared to propane. It is the reason why every dual fuel generator gives more power to gas as compared to propane. On the other hand, propane is cheap but does not have a high energy density than gas.

Run Time: When you consider small generators under 5000 watts, propane offers a better run time than gas. However, as the generator size increases, the run time for propane decreases and increases for gas. All the calculations for run time and power output have been made under controlled circumstances.

Availability and Shelf Life: Both fuels are available around the year. However, gas is difficult to find during times of natural disasters. In such situations, propane comes in handy. Why? Because it can be stored for a very long time as compared to gasoline. The shelf life of gas is 10-12 months, and that for propane is 8-10 years.

Safety: Propane is a safer fuel to use. There is no risk of spillage and storing a propane cylinder is more comfortable than storing gas tanks. However, managing propane cylinders is difficult on the go.

Each fuel type has its pros and cons. Therefore, a dual fuel generator is best because it can give you the best of both worlds.


Shall I go for a dual fuel portable generator or single fuel portable generator?

We suggest that you should go for a dual fuel portable generator. Why limit yourself when you can have freedom. A dual fuel generator will ensure that you don’t have to depend on one fuel during emergencies.

Which is better: an inverter generator or a conventional generator?

The answer to this question depends on your usage. If you plan to run only sensitive appliances on your generators like laptops, phones, TV, CCTV cameras, and inverters are the best. However, if power is your main concern, then look for conventional generators.

Is the wheel kit an essential feature to have?

Yes, a wheel kit must be part of your conventional generator to move it quickly. If your selected generator doesn’t come with a wheel kit, then you must buy it separately.

How loud are portable generators?

You will find different portable generators with different noise ratings. Inverter machines make less noise as compared to conventional ones. These portable generators’ decibel rating ranges between 55 dB (A) and 85 dB (A).

How to increase the run time on a dual fuel portable generator?

The best way to enhance the run time on any generator is to keep the load at half of the generator’s total power. However, on a dual fuel portable generator, you can increase the running time in another way. To do this:

  • Fill your generator’s tank with gasoline and connect a propane cylinder at the same time.
  • Let the gas run first.
  • When your generator stops, switch the fuel inlet to propane and start the generator again.
  • In this way, you won’t have to fill the gas tank during working.

What are the maintenance needs of a portable generator?

A portable generator needs a timely oil change, oil/air filter replacement, and spark plug inspection. It must not be overloaded and ensured that it is not run under snow/rain. Care must be taken while storing your generator. The best way to know about all the maintenance needs is to go through the user manual.

What are the pre-requisites for starting a new generator for the first time?

You must ensure that it has oil in it, the battery is charged (for electronic starting models), and there is fresh gas in the tank. It is best to run your new generator idle for 30-40 minutes to ensure that nothing is wrong with it and then add appliances one by one.

Do I need to ground a portable generator?

If you are powering your appliances directly, then you can skip the grounding step. However, grounding is necessary when connecting the generator to your home’s main electric supply.

For how much time a portable generator can last?

A portable generator can last for 1000-2000 running hours. Depending upon the use frequency, it will work for 10-15 years. You can enhance the working life of a portable generator through proper maintenance.

What are the limitations of a portable generator?

The only limitation a portable generator has limited power output. As compared to a standby generator, a portable generator does not deliver too much power. It doesn’t have an automatic on/off feature as well.

Final Words

We have explained everything about portable generators in detail. We hope that all the ambiguities in your mind have now been cleared. Select the best generator from the list above and stop worrying about power outages.
