Buying Guide for Dual Fuel Inverter Generator

Hopefully, you have read about our dual fuel inverter generator reviews. Now you must be familiar with all the good and bad features in a dual-fuel inverter generator. However, if you are still confused, then worry not! Because we have a buying guide ready for you, so you can choose the right generator for yourself.


The first thing that should come to your mind is that what size of generator do you need. Size is a very important factor to consider when buying a generator. There are many different sizes in which the generators are available. The sizes of the generator determine its other factors as well. these factors may include the fuel-tank size, engine, power outage, price, maintenance, and others. If you buy a smaller one. then you will be compromising on the output power; however, if you do not need a large amount of power, you should be fine. It all depends on what you need and what you can afford.

Some people need large dual-fuel inverter generators because they need to power large places, like big houses. Others might need a small dual fuel inverter generator, because they have a small place, or they need portable ones for trips like camping. Moreover, some people have a certain budget that they can buy it with. Large dual fuel inverter generators are more expensive than smaller ones. Therefore, they are many different factors that depend on this factor, which is why it is very crucial to consider.

Additionally, the size of the generator will directly affect the weight of the generator. Hence, if you buy a large generator, it is going to be pretty heavy and bulky. In this case, you need to consider if you will be moving the unit often or using it in a fixed place. If a lot of moving of the unit is involved, then a more bulky size is not the ideal one. This is because you do not want back pain from dragging the large machine everywhere.


2.Fuel Capacity

Another important factor is the fuel capacity of the generator. The fuel capacity is basically how big or small the fuel tank is. The smaller fuel tank means very little fuel capacity. why is that important? This is important to consider because less fuel capacity means that you will run out of fuel quickly and the running time of the generator will be very little. This means that you will need to refuel the generator repeatedly, which can be a hustle in itself. It is worth noting that the size of the fuel tank will also somehow affect the size and cost of the generator. A Large generator will have a larger fuel tank and it will also be expensive.


3.Output Power

Another crucial factor is considering the output power of the generator. It is measured in the unit Watts. The Power output of the generator is shown by the peak power and running output power. The peak watts is the highest value of power that the generator can provide while operating. However,  the running output watts is the average power that it produces while operating.

Dual Fuel inverter generators have two different fuels; therefore, these values double. this means that there are two different peak power values and two different running output power values for each of the fuels. These values will differ depending on the fuels and the manufactures as well. You need to have a minimum output power value in mind that the generator you will buy must have. An easy way to calculate that is to add up the power consumption (watts) of all the devices that you will be using on the generator.  this will give you the minimum power requirement, now just look for generators that meet your needs.


4. Starting Mechanism

The starting mechanism of a generator can be an important factor for some, while not so much for others. However, in our point of view, it is a factor worth considering. There are two main types of starting mechanisms. There is a recoil cord and the other is the electric start switch. The recoil cord needs a lot more effort to start, you need to pull it hard with strength. This type of starting mechanism requires not just more effort, but also more time.

On the other hand, the electric start switch is an easy way to start the generator, just flip a switch or press the button and it’ll start. this type of method requires a little extra electricity, therefore a small internal battery is added for this feature. However, this feature will not work if the internal battery’s charging runs out!

It depends on what you need or wants in your generator, a recoil cord, electric start switch, or both. Generators with both the features also come. however, we would recommend that people who live in places with freezing winters buy a generator with an electric start switch. this will be very convenient because no one wants to freeze out in winter trying to start a generator.


5.Noise Level

Most dual fuel Inverter generators are actually not that noisy compared to the non-inverter ones. However, that does not mean that they are not noisy at all. The one thing that is annoying about a generator is the noise pollution it creates. While some people might get used to the noise, others are pretty sensitive to it. Therefore, you need to decide whether you want a quiet generator or you are okay with a noisy one. Some people live in a neighborhood where it might create a very unpleasant environment for the neighbors because of the loud noise. In these cases, you might consider getting a quiet dual fuel inverter generator. In our list of best dual fuel inverter generators, all the generators are very quiet and peaceful.



Lastly, we have cost us our second factor to consider. It is obvious that we consider the price because everyone has their own budget that they can spend. Therefore, buying the right generator that is worth your hard-earned money is very important. When people are on a tight budget, they often end up buying the cheapest available stuff, which ends up being useless.

Even though you might have a tight budget, you should not buy the cheapest of the cheap generator. This is because, quality comes with a price; therefore, you cannot expect it to be even the slightest good. however, that does not mean that all cheap generators are bad. There are many budget-friendly options in the market like the one on our list as well. you just need to know the right features to look for!


The market has everything from best to worst, and you have to be smart and choose the right product for yourself. And this is why we have this buying guide made just for you, so you can buy the right dual fuel inverter generator. Hopefully, our list of best dual fuel inverter generators and our buying guide was helpful to you in any way. I hope you liked our article, which was written after immense hard work and research.

What’s an Inverter Generator?

An Inverter Generator is different from a non-inverter generator because it first converts the AC current to DC current and then again converts it back into AC current. The inverter generator throttles the engine in an up and down. This mechanism results in much more fuel efficiency because of which you do not run out of fuel easily. Moreover, this type of generator is much quieter and gives out fewer emissions. overall, they are an advanced and much better unit than the non-inverter ones.

What is the best dual fuel inverter generator?
