5 Quietest dual fuel generators reviewed in-depth
If you know more or less what you want, the overview of the quietest dual fuel generators and the performance table could be enough to make a decision.
That being said, the more in-depth reviews of all the options below can help you make sure you are choosing the right model.
1. A-iPower SUA2000iD – Quietest dual fuel generator
The first few models have similar decibel ratings and noise levels customer mentions.
However, because the smallest models tend to be the quietest generators, this A-iPower SUA2000iD gets the top spot.
At the same time, it is worth noting that you will likely prefer one of the other quiet dual fuel generators in terms of quality, price, and specifications.
The A-iPower SUA2000iD is not necessarily bad but there are just a few too many cases of challenging starts and technical issues.
Pros
- Relatively low noise levels of 52 dB
- A-iPower SUA2000iD offers 2000 starting watts, 1600 running watts, 16.7 amps, and 120 volts (gasoline)
- Parallel capability
- Run time of 10 hours at 25% load
- Less than 3% THD
- Light weight of 48 lb (21.8 kg)
- 3 years limited residential and 1 year limited commercial warranties
Cons
- Gasoline fuel efficiency is not that good
- Some cases where the first few starts were challenging
- Some cases where the first generator customers got did not work as desired
- You may need more power
Additionally, while 2000 peak watts and 1600 running watts can run things like an energy-friendly refrigerator, coffee machine, TV, etc., this is not the most impressive power capacity either.
The fuel efficiency (kWh per gallon of gasoline) of the A-iPower SUA2000iD is not that good either.
This could cost a bit more if you plan to use your dual fuel generator a lot.
And even if you plan to move your dual fuel generator a lot during your camping, tailgating, fishing, or other activities, you will likely still prefer one of the A-iPower SUA2000iD alternatives.
| Brand Model | Quiet Operation | Power Capacity | Run Time | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| A-iPower SUA2000iD | 9.5 | 6.5 | 8 | <3% | 7 | 6 | 7.5 | 9 | $$ | Check Price |
2. DuroMax XP2300iH
The DuroMax XP2300iH is not just similar to the A-iPower SUA2000iD in terms of noise levels. It has its number of technical issues too.
Some customers also mention they find it hard to get help from support although there are people with good experiences too.
These two quiet dual fuel generators have a few important differences too.
For example, the 13 hours of run time at 25% load and the impressive gasoline fuel efficiency of the DuroMax XP2300iH are better.
Pros
- Relatively low noise levels of 52 dB
- DuroMax XP2300iH offers 2300 starting watts, 1800 running watts, 19.2 amps, and 120 volts (gasoline)
- Parallel capability
- Nice run time of 13 hours at 25% load
- Good gasoline fuel efficiency
- Clean THD is suited for sensitive electronics
- Light weight of 53 lb (24 kg)
- CO sensor
- 3 years limited residential and 1 year limited commercial warranties
Cons
- A few cases of technical issues
These things can be helpful for things like running a refrigerator throughout a night of power outage and/or saving some money on gasoline.
Some people will also like the CO sensor. This adds a layer of safety to avoid too much carbon monoxide buildup around the dual fuel inverter generator.
So the DuroMax XP2300iH is a decent model that definitely deserves a spot on the list of the quietest dual fuel generators thanks to the noise levels.
At the same time, the technical issues make this option feel a bit lacking in terms of price value. You may prefer the next model instead.
| Brand Model | Quiet Operation | Power Capacity | Run Time | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| DuroMax XP2300iH | 9.5 | 7 | 8.5 | Clean THD | 7 | 9 | 7.5 | 8.5 | $$ | Check Price |
3. WEN DF250i
Besides the quiet operation and dual fuel feature, another reason to consider the WEN DF250i is its high place on the list of the best 2500 watt inverter generators.
With a 2500 watt generator, you can run things like an 11k BTU RV air conditioner, an electric grill, and certain circular saws.
You can also use the WEN DF250i to run multiple smaller appliances and tools for your camping trip, construction work day, or even power outage backup challenges.
One thing you do want to keep in mind is that the WEN DF250i specifically does not have that many customer reviews yet.
Pros
- Relatively low noise levels of 52 dBA
- WEN DF250i offers 2500 starting watts, 2000 running watts, 16.6 amps, and 120 volts (gasoline)
- Parallel capability
- Good run time of 6 hours at 50% load
- Less than 1.2% THD
- Light weight of 48.5 lb (22 kg)
- 2 years limited residential and 90 days limited commercial warranties
- Budget-friendly
Cons
- Relatively short commercial warranty
- Not that many customers for this specific model
This low number of customer reviews adds some uncertainty about the quality of this specific model.
At the same time, WEN generator customers tend to be positive overall.
Something that positively stands out is the light weight of 48.5 lb (22 kg). This portability can be helpful for situations like busy camping trips with many stops.
In other areas, the WEN DF250i is relatively standard but solid.
This is actually a benefit when you consider the low investment required for this quiet dual fuel inverter generator.
| Brand Model | Quiet Operation | Power Capacity | Run Time | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| WEN DF250i | 9.5 | 7.5 | 8 | <1.2% | 7.5 | 6.5 | 7.5 | 9 | $ | Check Price |

5. Champion 200961 2500
The extra decibel at 25% load of the Champion 200961 2500 will likely not influence your experience too much.
However, since this is still the list of the quietest dual fuel generators, this quiet Champion generator does get a lower spot.
In turn, this also means that the combination of a better reliability reputation and a portable weight could still make the Champion 200961 2500 the best option for you.

FAQ
Are dual fuel generators quiet?
It is often said that generators running on propane tend to be quieter than models running on gasoline but tests of dual fuel generators do not always conclude the same.
In turn, whether or not dual fuel generators are quiet can vary from brand model to brand model and what you consider to be silent operation.
What is the quietest dual fuel generator?
The A-iPower SUA2000iD is the quietest dual fuel generator on this list with a rating of 52 decibels (typically measured at 25% load and 23 feet away).
That being said, if you want a dual fuel generator with good portability, you will likely prefer the WEN DF250i in terms of quality and price.
Additionally, the Westinghouse iGen4500DF can be a great choice if you want more power and don’t mind the extra weight and dimensions.
