These factors help you understand what do you need and what you should get against your hard earn money.

Let’s explore the factors without wasting any more time.

Tank capacity of both fuel sources and running time

The dual-fuel generators are ideal for everyone as it comes with different fuel tank capacities. However, the gas fuel tank may differ from the propane tank but no worries, at the time of purchase you will get to know the appropriate size of propane tank your generator needs.

Yes, the tank size plays a vital role as the running time of your generator depends on it. The large tank you got, the more running time you buy. Also, fuel type decides the running time as you can experience long-running hours with gasoline as compared to the propane.

Starting and Running Watts

It is the most crucial factor that one should consider before buying any generator. It is useful if you know the peak and ratted watts of your generator, but since you are planning to buy a dual fuel generator, you should focus on watt ratings of both fuel sources.

We are hoping that you are clear about your generator need. Like, whether you are buying it for your occasional outdoor parties or your only purpose of buying it to keep your home appliances running through thick and thin. So, if your buying purpose is entertainment, then you can consider low power output provider generator. However, in another case, you may need a high power output to run multiple heavy power tools.


It is going to be an issue if you have to move your generator for different usages. Your generator should be portable and easy to carry. Some generators do come with mobility kits or accessories for users convenience. Do not forget to test their functionality, as if they are strong enough to carry the weight and move around. They must come with comfortable handles for easy movement.

Safety Features

A best dual fuel generator without safety features is a waste of money. Avoid getting a generator that doesn’t come with a low oil shutoff system. This feature automatically senses when your generator is short on fuel and shuts off to protect it from any damage. There are also other features like overload protection and overheating protection that you should consider before choosing any generator.

Conventional Vs. Inverter Generators

There are two major types of dual fuel generators; conventional and inverter. Both are going to meet your power needs and are exceptional in their performances. However, people prefer to buy invertor one as it is more fuel-efficient. Also, the inverter dual fuel generator makes less noise as compared to its alternative and is more portable. Yes, it is quite expensive, but worth the money. So, decide beforehand what type of generator you need and afford to have in a house.


It is better and useful to have a monitoring system over your generator. It would be easy for you to keep track of complete information about oil or fuel levels, and other general requirements of the device.  Many generators have LED light displays and indicator lights for your convenience. Consider buying the one with such features.

Noise levels

We all know that we can measure noise or sound by a unit decibels (dB). And, the higher number of decibels means the possible loud noise. We assume that generators are supposed to make noise; it is the nature of the device. Sometimes, brands produce devices with a calm noise level. We advise you to choose a dual fuel generator with 60 dB or below the numbers to get an ideal noise level.

Emergency Tips for Generator Users

The regular power outage is okay, but if you sense that it is not going to come in the next few hours than you know it’s time to use your adequate investment for power needs. And to have the most benefits out of it, you should consider following these tips for better performance in emergency times.

Propane over Gasoline

We discussed that propane is readily available at your nearby gas stations, and you can get the tank from any hardware store in the area. So it would be a wise decision for any generator owner to store propane over gasoline. Gasoline may harm your health, and you cannot save it for emergency times. Besides, refuelling the propane is mush easy than gasoline. You just have to replace the empty tank of propane with the full one, and boom you are ready to use.

Another reason for opting propane over gasoline is its cost-efficient property. It is a less expensive fuel source for a generator than gas. So, if you have to run the machine for the whole day or night, then switch it to a propane source.

Buy a user-friendly generator

Always watch out functioning and features of the generator before buying. It is best if it is a user-friendly one and comes with a detailed user manual. Because in case of emergencies when you can’t understand the issue, you can at least call your local technician to do the job. Be smart beforehand, and get the easily understandable one.

Kinds of Generators

There are usually two kinds of generators available in the market; single fuel and the dual fuel generator.

  • Single fuel is the standard one that everybody knows about; it usually runs on a single fuel source and can not guarantee running time. Gasoline is a fuel source that is responsible for running a generator.
  • The other kind of generator is dual fuel one. It can rely on both gasoline and propane at the same time. You can easily switch between the sources and increase the running time of the generator. Besides, propane is eco-friendly and less expensive as compared to gasoline.

Why Get a Dual Fuel Generator?

The idea of investing in a dual fuel generator sounds complicated to most people because they are not aware of its usage and durability. However, it is a great and user-friendly device with lots of benefits to enjoy. Of course, it’s a complete package for homeowners who worries for their safety in stormy nights.  If you fear to face any emergency, then having a dual fuel generator will not a wastage for you.

The dual fuel generator is an eco-friendly product because a fuel mixture can offer relatively lower emissions than other usual generators that run solely on diesel. What else is better than a product that not only ideal for your house but also serves the environment. Besides, natural gas can provide a longer running time, so businesses use gas and diesel mixture to run a generator instead of only diesel use.

Natural Gas Availability

Easy availability of natural gas from nearby is another benefit of having a dual fuel generator. Also, it is relatively less expensive than diesel.  In case of emergencies and sudden storms, the natural gas will be available to you. Moreover, natural gas burns cleaner than diesel, that eventually reduces the need for storage and oil maintenance cost.


The best dual fuel generators are economical to run even with increasing prices of natural gas. It will reduce the considerable burden of electricity cost from your shoulders and provide you with an ocean of power at an economical price. In modern times, people use this type of generators in hospitals, schools and other important places where they can not afford to spend hundreds of dollars over electricity while experiencing power outage every hour. As far as you fill-up the generator and fulfil its needs, it won’t let you stay in the dark.

Peace of Mind

You are going to have a peace of mind by having a dual fuel generator even after your area supply company lost hopes. You no longer have to waste hours or days without electricity in your homes. Besides, in case of natural disasters, such as earthquake, heavy rains and storms may restrict you to go out and help yourself for the electricity needs.

However, if you are dependent on the generators that run on that one type of fuel, then you also find yourself in trouble when you would be limited to your gasoline storage at home. But, with dual fuel generators, you may only have to plug in your propane tank. The exciting thing is, you can store propane for a longer time as compared to diesel, and it can be readily available at any gas station or hardware store.

Isn’t it a peace of mind?


You are never going to run out of options with two fuel types in a single generator. You may like to use gasoline, but propane can be your most generous backup under challenging times. The best dual fuel generator is an incredible and reliable product that stays with you for a longer time, as it offers unpredictable lifespan.

Moreover, propane is safer to store as compared to gasoline and diesel. You can keep it for days, months, even for a year. It will be your safety partner and a backup plan in long summer days. Besides, you can easily exchange or fill up the propane tank from any gas station.

Watts Rating

While getting a dual fuel generator, you must know how much power you need and its corresponding wattage because you may feel that each dual fuel model shows the difference in wattage ratings, a lower for propane and a higher for gasoline. So, the wattage output depends on whether the generator is running on propane or gasoline. You should be considerate and learn beforehand about the concept, and make the purchase accordingly.
