Best Dual Fuel Portable Generator

Not all generators work with the same fuel. Imagine buying a very good generator, but having to spend a lot of money to go and buy the fuel it works with from a far away store. Or how about all those times when you wanted to combine two types of fuel to make your generator more efficient, but weren’t able to do that because the generator didn’t support that option? These can be major inconveniences, and if you’re in a situation like this, it’s time to look for other options. The simplest but best solution to this problem would be to get a dual fuel generator. With a generator like this you’ll be able to use the two types of fuel of your preference both combined and separately. This is a more flexible option than other generators out there, and things are even easier when the generator is also portable. Just in case you were wondering what the best dual fuel portable generator was, here are our top three answers to that question

1. Champion 76533 Dual Fuel Portable Generator

Champion 76533 Dual Fuel Portable GeneratorBriefly on the Generator

This review will go over all the good and bad features of the Champion 76533 generator with a dual fuel which is very portable as well as RV ready with 3800 watts. This generator is quite impressive if we may say as it is incredibly affordable and it produces really good amount of power. Of course, there are some other things that puts this generator on top of the list.

How Powerful Is the 76533?

We should start off with the power output and the engine. The Champion 76533, like said in the title, has a duel fuel and is run on 3800 watts. It’s also powered by a dual fuel hybrid 224 cc engine. This generator, therefore, will be able to run either on gas and propage or, shortened, LPG. This is great news for those who really care about the environment.

There are a few advantages if you decide to use propane gas. One of the reasons is that it makes clean burning possible with low emissions. Another reason is that propane is much more easily transported or stored if you are looking to travel. Also propane doesn’t take much of space once you put it in a compressed form. The generator will also last you much longer with a propane tank than with a gas tank of the same size.

When it comes to the overall power output, the Champion 76533 generator has a running power of 3,800 watts and a startup load (peak power) of 4,750 watts. This power output is like that when you run the generator on gas. However, if you decide to use propane, the power will be less with 3,420 watts of running power and the 4,275 watts of peak power.

No matter which one you choose, you will be able to use any RV. You will also be able to power up any of the household electric devices in case of a blackout. If you’re a contractor or a farmer, you will be happy to find out that you can also power up several tools and the generator will be able to run most water pumps.

General Features?

The Champion 76533 generator has an electric starter. This is a great feature because it’s much more user-friendly and it’s much better for cold weather. A lot of people have problems with starting up a recoil starter but this generator won’t require you to know how to start the recoil starter.

The gas tank can store up three-point-four gallons of oil. This means it can run for six to nine hours (6 hours will be on 60% of the load, 7 hours on the 75% of the load). However this is on gas, but with a 20LB propane tank, you will be able to run it for 10 hours even.

When it comes to power outlets, the generator has one RV power outlet of 120 volt and one 30A locking outlet. There are also two outlets which are standard made for household of 120 volt. There are circuit breakers that cover these outlets. The VoltGuard Technology is built in as well which is great help in protecting electronic devices in case of a voltage surge.

You will be able to find that there is a digital display which shows voltage, running hours and frequency. There are other features such as a low-oil shut off sensor and a USDA approved spark arrestor. The generator is approved by EPA and CARB-compliant and can be used in all 50 states of the US.

Noisy or Not?

If you’re interested in how loud the generator is, you will be impressed by this generator. In fact, the Champion 76533 generator is one amazingly quiet generator despite its size. With 23 feet way, this generator has a noise rate of 68dBA. This can be compared to the noise of a regular talking voice. On a bad note, this generator might be a little heavy for some however it is incredibly sturdy and comes with a large engine. But it is still quite durable and very portable as it comes with a wheel kit.

1. Are dual fuel generators the same as bi-fuel generators?

No, they are not. Duel fuel generators are called that because they can use two different types of fuel at the same time to power your devices and electric appliances. When you’re powering something with a duel fuel generator, you have to mix the two types of fuels on your own. You can choose to put as much or as little from each fuel as you deem to be necessary for a certain situation. However, you can also choose to let your generator run on one type of fuel only by not mixing it with a different type of fuel.

When it comes to bi-fuel generators, they use two types of fuel, but they alternate between them automatically. These kinds of generators toggle between the two fuels depending on the which type of fuel is more suitable to power a device at a given moment.

2. Is it cheaper to use propane or gas for my generator?s?

It is usually gas that is the cheaper option.


These are just some of the best dual fuel portable generators. These types of generators are incredibly useful for all sorts of different activities as they are very convenient. Hopefully you will be able to make an informed decision.
