We’ve been testing the Champion 4250-watt Generator, and it’s a beast when it comes to power and performance. The dual-fuel feature is super handy—it’s great to have propane as a backup when gasoline isn’t readily available. Switching between the two is a breeze, and the runtime on propane is decent for moderate use.
What really stands out is the Quiet Technology. For an open-frame generator, it’s surprisingly quiet. Even while running several appliances, the noise stayed at a tolerable level, which is perfect for RV parks or outdoor gatherings.
That said, it’s not the most portable option. While it does have a sturdy handle and wheels, the weight can make it a bit challenging to move solo. Also, under heavy loads, propane burns through a little faster than we expected, so it’s worth planning ahead for longer use.
All in all, the Champion Power Equipment 4250-Watt Dual Fuel Generator is a reliable powerhouse. If you need a generator that’s flexible, powerful, and quieter than most open-frame models, this one’s a solid investment. It’s perfect for outdoor enthusiasts and homeowners who want a dependable energy backup.

The standout feature for us is how quiet it is. Even while powering several appliances, the generator hums along without disrupting the environment, which is a blessing if you’re camping or in a residential area. The power output is equally impressive—it easily handled our fridge, microwave, and a few smaller devices without breaking a sweat.
That said, it’s not the most portable option out there. While the wheels and handle help, its weight makes it a bit of a challenge to move around frequently. Also, propane burns through faster than we’d like under a heavy load, so it’s worth keeping extra on hand for longer use.
In conclusion, the Westinghouse 5000 Watt Dual Fuel Generator is a great buy for anyone who needs a generator that will keep it cool (and quiet) on the job. It’s perfect for powering your home during outages, supporting RV trips, or keeping the lights on during outdoor events—all without the usual generator racket!

If you're looking for a compact yet powerful generator that’s perfect for outdoor adventures or light home backup, the Pulsar 2,200W Portable Dual Fuel Quiet Inverter Generator (PG2200BiS) is worth considering. This generator is built for convenience and reliability with its dual-fuel capability, USB outlet, and quiet operation.
We’ve tested the Pulsar PG2200BiS, and it’s a fantastic little generator for on-the-go power needs. The dual-fuel feature is especially useful—it’s great to have propane as a backup option when gasoline isn’t readily available. Plus, switching between the two fuels is smooth and hassle-free.
What stands out is its quiet operation. The quietest of most traditional generators, this is great for camping, or to power sensitive electronics without irritating the neighbors (or the wildlife!). The USB outlet is a nice bonus—we weren’t expecting to be able to simply plug devices in to charge without adapters, but it was great.
All things considered, this generator is designed for light use. It worked like a champ on our smaller appliances and devices, but bigger setups that call for more power did not go well. For light use, the propane runtime is decent; however, if we push it harder, it fails, so we should plan accordingly.
Overall, the Pulsar 2,200W Portable Inverter Generator is a reliable choice for anyone seeking a compact, dual-fuel generator with modern features. It’s great as a back up for smaller household needs or for tailgating or camping. This generator suits you if you value portability and quiet operation.

Why Choose Dual Fuel Generator Over Single Fuel?
It’s always good to have options. Believe it or not, there are some regions where gasoline is more expensive or more easily available than propane and vice versa.
Having a generator that lets you choose between two options puts you in a great place as you can pick one that you can easily get your hands on, especially in tough situations where access to fuel is limited.
Which Fuel Type to Use?
Propane is cheaper and easily available while gasoline can be a bit expensive and hard to find.
Apart from that, propane is safer for the environment as it emits less harmful gases when compared to gasoline.
Other than this, consider your regional temperature as well when choosing a fuel.
Gasoline might be a cheaper option but it is consumed very quickly. This is because heat makes it evaporate faster. Hence, it may not be suitable for very hot regions.
Similarly, living in a colder region can be a bit problematic for people who are thinking of using propane. This fuel begins to contract below 40 degrees. Hence, it may not be suitable for very cold regions.
Best Dual Fuel Generator Buying Guide
Now, the question is how to choose a dual fuel generator that offers plenty of features and is suited as per your needs.
There are a number of products on the market, hence picking one can be quite a challenge.
To make it easier for you, here are a few factors you should consider when selecting a dual fuel generator:
- Regional Temperature: Believe it or not, your regional temperature can make a lot of difference when selecting a generator.
First of all, some generators do not start well in winters as the engine may get frozen. This is why for very cold areas, you should go for a generator like Champion 7500-Watt Dual Fuel Portable Generator with Electric Start. Its cold start feature ensures you have no problem in turning it on even when it’s snowy outside. - Power: This is a no brainer. Generators offer limited power, hence you must know exactly how much power you need so that you can pick the right generator.
As a rule of thumb, appliances that involve heating or cooling (ACs, refrigerators) require a lot of power. If you want to run such appliances, you will need to go for a unit that provides at least 5000W of power, such as Pulsar 5,250W Dual Fuel Portable Generator with Switch and Go Technology.
It’s a powerful generator that is made to run almost all home appliances. - Types Of Appliances You Want To Run: This is important to ensure all appliances can run without any trouble.
You have to pay attention to two features: outlets and the sensitivity of appliances. Some appliances, such as laptops, are sensitive and require continuous power as fluctuations can be bad for them.
We suggest you go for Powerhorse Dual Fuel Generator 9000 Surge Watts if you want to run a variety of appliances including sensitive appliances.
It produces a total harmonic distortion of less than 5% and offers 10 connectable outlets, making it suitable for a variety of uses. Plus, you can even use it outdoors and to run RVs. - Safety: Some of the most common safety features you need to look into are: low oil indicator, voltguard protection, voltmeter, and overheating protection. These features are not only important for the safety of generators and other appliances, but also for the safety of your family members.
They ensure the generator shuts down automatically if anything goes wrong, so be sure to look for these features when picking a dual fuel generator. Champion 3800-Watt Dual Fuel RV Ready Portable Generator can be a good choice as it’s safe to use and is also environmentally friendly. - Noise: Pay special attention to this factor as noisy generators can be a pain to handle. While big generators tend to be noisy, some now come with mufflers and other features to suppress the noise so pay special attention to such features.
Anything under 40 dB is said to be acceptable as it only equals to slight whispering but generator above 50 dB can be very noisy.
Every 10 dB increase means the generator is ten times louder. Here’s a small breakdown:
Noise Level (Decibels) | Sound |
|---|---|
20dB | Rustling Leaves |
30dB | Whisper (5 meters) |
40 dB | A bunch of people having a conversation at a distance. |
59dB | Constant laughter |
60dB | People talking right behind you |
70dB | Vacuum Cleaner |
90dB | City Traffic |
110 – 120dB | Night Club / Rock Concert |
- Price: Heavy duty generators will obviously cost more than low-powered dual fuel generators. If you wish to run a few appliances then you won’t need to spend a lot of money and can get a small to medium ranged dual fuel generator.
However, if you wish to run heavier appliances and lots of them then you will need a heavy duty generator like DuroMax Hybrid Dual Fuel XP12000EH 12,000-Watt Portable Generator. It is quite powerful and offers excellent run-time as well.
Best Dual Fuel Generator: FAQS
Q. Is it wise to charge sensitive electronics using a dual fuel generator?
Ans. Sensitive electronics aren’t able to withstand voltage fluctuations and may easily sustain damage. To avoid your delicate electronics from burning up, make sure to choose a generator that offers clean energy.
Some generators use sine wave technology and have features to prevent fluctuations.
Q. How can I lower the noise of a loud generator?
Ans. While it won’t make a lot of difference but keeping them elevated can help. This is because generators vibrate on the ground and produce more sound. Keeping them above the ground will minimize noise.
Apart from that, buy an extension cord and place them at a considerable distance for additional safety.
Q. Can I use dual fuel generators outdoors?
Ans. Yes, depending on the make and model. Many dual fuel generators are perfect for outdoor use.
The Bottomline:
These were some of the best dual fuel generators that you can opt for. Make sure to identify your needs first and then choose the right one.
