What are Portable Dual Fuel Generators?

Portable dual fuel generators are generators that use two types of fuel at the same time. In most cases when it comes portable dual fuel generators, they will use gas and propane to power up the engine and generate electricity.

These generators are also portable, meaning that they can be moved around thanks to a set of wheels. Some of them are also appropriate for RVs and for camping, as they are more lightweight than most stationary dual fuel generators.

Depending on the situation and use, dual fuel generators provide more flexibility and better efficiency, as we are able to choose between two types of fuel for powering the generator. For example, when we run out of gas, we can use propane to power the generator, extending the running time of the device.

Here’s how a portable generator works.

How Long Will a Dual Fuel Generator Run on Propane?

A dual fuel generator will run for between 5 to 10 hours on propane. That depends mainly on how much propane the generator can hold, and at what capacity we are using the generator.

Most users tend to run generators at 50% loads, which can increase the running time on propane. Normally, generators will rely primarily on gas, which will last longer than propane. However, when the generator runs out of gas, it will automatically switch to propane, extending the running time.

What Makes a Good Portable Dual Fuel Generator?

So what are some main qualities that we should look out for when choosing a portable dual fuel generator?

1. Power

The biggest factor to consider is arguably the power the generator can provide. A good way to figure out how much power you will need from the generator is to calculate the power all your appliances will need.

For running an entire household, at least 7000W of power will normally be needed, although it can be even less. Some users will find a 12.000W dual fuel generator more helpful, as it will be capable of covering their needs.

If you’re looking for a good portable generator for traveling, then you don’t need that much power. That will save you space and give you some extra points in portability.

2. Portability and Mobility

One key factor to consider is just how portable the generator is. This includes its weight, how easy it is to be transported, and whether it needs additional purchases to make it more portable.

Most of portable generators will come with a set of wheels at the very least. However, some portable generators are specifically made for RVs, which increases their usefulness if you’re someone who likes to go out camping and needs a source of electricity.

3. Noise Levels

A noisy portable generator is something that nobody wants to have. You will want to ensure that the generator is not too noisy for your needs.

Sure, if you’re looking for a generator for industrial needs, then noise levels might not matter that much. But for outdoor use, for camping or RV, or even for home use, a noisy generator can be a nuisance.

Look out for the noise labels on each generator (if they have them), which can make your decision much easier.

4. Ease of Use

A good portable generator should be easy to use. This includes one-touch electric start and easy control over the generator.

If a generator has a monitor where you can see oil levels, fuel levels, and the status of the unit, then that’s a bonus. It enables you to have a more satisfactory and better experience with the unit.

For all beginners out there who have never used a portable generator before, we advise you that you look out for a portable generator that starts easily and has the features we mentioned above. However, most generators are actually quite easy to use, and they also come with manuals. It might take some learning, but it should get easier with practice.

5. Security

Security is a major factor when choosing a portable generator. Ideally, a portable generator should have security measures such as control and safety mechanisms against overheating, low oil shutdowns, and overload.

Look for models that come with additional safety features if you’re that concerned about safety. But most newer models will have these features.

Is It Cheaper to Run a Generator on Gas or Propane?

Running the generator on gas will be cheaper in most cases. Provided that you do not live in an area where propane is proportionally cheaper than gas, then you will most probably spend less on gas and get more out of the fuel.

But the main usage of propane in dual fuel generators is to provide another layer of flexibility in case you get left without gas and you don’t have access to gas. You can expect the costs to be visible on the long-term, although the differences between gas and propane are not that significant.

1. Are Propane Generators Better Than Gas?

A great advantage a propane generator has over gas generators is that it has a much cleaner performance, as it won’t emit nearly as many toxins. It’s better both for you and the environment. When you need more power, gasoline might be better; however, if you’re looking for a cleaner performance, propane is better.

2. Do I Have to Ground a Portable Dual Fuel Generator?

Most portable generators will need to be grounded before you start using them. However, most will feature a design with a metal frame that will provide the path of least electrical resistance for the electricity. Most generators will come with a manual included, where you will see clear instructions as to how to ground your generator. In any case, it’s recommended to consult this manual before you start using the generator so that you can easily ground it.

3. How Big of a Generator Do I Need to Run a House?

Anywhere between 8000w and 12.000W will be enough to power an entire household. Although that will depend on how much electricity your home will need. If you have many appliances at home, then you will need more power to power your appliances. Such generators are relatively larger, but they will also provide much more power. The problem is that these generators can get heavy, so you might compromise on portability slightly.

4. How Often Do I Need to Refuel the Generator?

It will depend on how often you use the generator, what the fuel tank size of the generator is, and how much the generator consumes. Dual fuel generators are great in this respect as you don’t need to refuel them as often, as you can easily switch between gasoline and propane once the gas runs out. Normally, if you use the generator constantly, it will last you anywhere between 8 – 12 hours, depending on how much power you use.
