5 Best dual fuel inverter generators reviewed
People who know more or less what they want could use the list of top picks and the performance table to make a choice.
That being said, you will likely find it easier to choose the best dual fuel inverter generator for your situation after checking out the detailed reviews below.
1. Westinghouse iGen4500DF – Best dual fuel inverter generator
Our top pick for the best dual fuel inverter generator is the Westinghouse iGen4500DF thanks to its popular power level, solid features, good reliability, and reasonable price.
You can also get this model with remote start and thanks to the TT-30R outlet, the Westinghouse iGen4500DF is easier to connect to certain RVs and campers.
In simpler words, this generator also gets the top pick spots for the best dual fuel inverter generator with remote start & for RVs.
One of the first things that positively stands out is how quiet the Westinghouse iGen4500DF is.
The noise level rating of 52 dBA is the quietest on this list too.
Pros
- Westinghouse iGen4500DF offers 4500 starting watts, 3700 running watts, 30 amps, and 120 volts (gasoline)
- Parallel capability
- Dual fuel feature allows you to run on propane (LPG) too
- Relatively low noise levels of 52 dBA
- Long run time of 18 hours at 25% load (gasoline)
- Less than 3% THD
- Has electric start and optional remote start
- A lot of performance tracking metrics
- Optional CO sensor
- Weight of 104.7 lbs (47.5 kg)
- Very positive customer reviews
- 3 years limited residential and 1 year limited commercial warranties
- A lot of customers
Cons

- Can be challenging to move over bumpy terrain
In combination with the long gasoline run time or a big propane tank, the Westinghouse iGen4500DF is great for running things like a small AC, refrigerator, or freezer throughout the day or night.
Additionally, the performance tracking metrics on the LED screen make it easy to see how many more watts you can use.
The positivity of all the customer reviews also implies the Westinghouse iGen4500DF is a very reliable inverter generator.
One thing you do want to keep in mind is that the small wheels make it somewhat harder to move the Westinghouse iGen4500DF over bumpy terrain.
That being said, with how good this dual fuel inverter generator is in other areas, this is likely still the right choice if 4500 peak watts (gasoline) is enough for you.
| Brand Model | Power Capacity | Run Time | Quiet Operation | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| Westinghouse iGen4500DF | 8 | 9 | 9.5 | <3% | 9 | 8 | 8 | 8.5 | $$$ | Check Price |
2. Champion 201175 – Best dual fuel inverter generator for home backup
When it comes to portable home backup generators, you typically want more power, extra good reliability, and preferably a 50 amp outlet.
If these sound like details you want, the Champion 201175 8500 is often the best dual fuel inverter generator for home backup power.
The main thing you do want to keep in mind is that this is not the most proven Champion generator. There are not that many reviews yet.
If you don’t like this, you could consider the DuroMax XP9000iH (although the reliability does not look ideal).
That being said, because of the low rate of technical issues in other Champion generators, this Champion 201175 still gets the top spot.
Pros
- Champion 201175 offers 8500 starting watts, 7000 running watts, 50 amps, and 240 volts (gasoline)
- Dual fuel means generator can run on propane (LPG) too
- Relatively low noise levels of 61 dBA
- Run time of 14 hours at 25% load (gasoline)
- Less than 3% THD
- Electric start
- Four GFCI outlets
- CO sensor
- Weight of 213.9 lb (97 kg)
- 3 years limited residential and 270 days limited commercial warranties
Cons
- Not a lot of customers yet
- Somewhat pricey dual fuel inverter generator
Another thing that positively stands out in the Champion 201175 8500 are its low noise levels of 61 dBA at this power level.
Considering a regular conversation is around 60 decibels, you could use this generator to power an AC system, refrigerator, and/or freezer throughout the night.
Besides that, the electric start is not quite the remote start of the Westinghouse iGen4500DF but does make your experience more convenient.
So if you don’t mind the lower number of reviews for the Champion 201175 8500 specifically and need a lot of power, you could consider investing in this large dual fuel inverter generator.
| Brand Model | Power Capacity | Run Time | Quiet Operation | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| Champion 201175 | 9.5 | 8 | 8.5 | <3% | 8.5 | 8 | 7.5 | 6.5 | $$$$$ | Check Price |
3. Champion 200977 – Best small for power outages
The Westinghouse iGen4500DF is relatively reliable but for some situations like power outages or off-grid living, you really want all the reliability you can get.
Additionally, you may find the previous Champion generator a bit too big for your needs.
If these things apply to you, the Champion 200977 4250 could be the right dual fuel inverter generator for you.
Something you do want to keep in mind is that this portable generator does not come with wheels.
That means you will either have to carry the 79 pounds (35.8 kg) or invest in a separate wheel kit.
Pros
- Champion 200977 offers 4250 starting watts, 3500 running watts, 30 amps, and 120 volts (gasoline)
- Parallel capability
- Dual fuel feature allows you to run on propane (LPG) too
- Reasonable noise levels of 64 dBA
- Long run time of 22 hours at 25% load (gasoline)
- Less than 3% THD
- Weight of 79 lb (35.8 kg)
- Very positive customer reviews
- 3 years limited residential and 270 days limited commercial warranties
- A lot of customers
- Relatively budget-friendly
Cons
- No wheels so moving the generator can be challenging
- A few very exceptional cases where the first model customers got had issues
On the flip side, the Champion 200977 4250 is also good in other areas besides reliability.
For example, if you do decide to use gasoline, you will be able to enjoy the low THD clean inverter power for a long time before having to do a refuel session.
Additionally, while the noise levels of 64 dBA definitely do not make it the quietest dual fuel inverter generator on the list, the Champion 200977 4250 is still reasonable in this area.
So while the Champion 200977 4250 is not perfect, having a reliable dual fuel generator for power outages could save your refrigerator full of food.

4. A-iPower SUA2000iD – Quietest dual fuel inverter generator
You may notice that the A-iPower SUA2000iD has the same noise level rating as the Westinghouse iGen4500DF.
However, in the absence of good noise level tests, this small option gets the top pick for the quietest dual fuel inverter generator
At the same time, while it is nice knowing this model exists, it is likely not the best dual fuel generator for you.
With only 2000 peak watts and 1600 running watts, the A-iPower SUA2000iD is only strong enough for small devices.
A more power-hungry refrigerator is already too much.
Pros
- A-iPower SUA2000iD offers 2000 starting watts, 1600 running watts, 16.7 amps, and 120 volts (gasoline)
- Parallel capability
- Quietest dual fuel inverter generator with noise levels of 52 dB
- 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, there are many people who are happy with their A-iPower SUA2000iD but the rate of technical issues is somewhat high.
The suboptimal gasoline fuel efficiency also makes the kWh you get somewhat pricier.
On the flip side, a benefit of keeping things small is that this portable dual fuel inverter generator is easy to carry and compact to store.
If you really want the quietest dual fuel generator and don’t need that much power, you could consider the A-iPower SUA2000iD.
That being said, you will likely prefer one of the other options on this list anyway.
| Brand Model | Power Capacity | Run Time | Quiet Operation | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| A-iPower SUA2000iD | 5.5 | 6.5 | 10 | <3% | 7 | 6.5 | 7.5 | 10 | $ | Check Price |
5. AIVOLT 10000 – Largest dual fuel inverter generator
The Champion 201175 8500 already offers a good amount of power but if you really want the largest dual fuel inverter generator, you can consider the AIVOLT 10000.
Before doing so, you do want to know this is not the most proven generator brand.
In combination with the low number of reviews for this specific model, there is a certain risk in terms of the quality of the AIVOLT 10000 at a bigger scale.
You may also need some help moving the heavy weight of 299 pounds around (135.6 kg).
At the same time, the AIVOLT 10000 positively stands out in other details than its 10000 peak watts too.
Pros
- AIVOLT 10000 offers 10000 starting watts, 8000 running watts, 50 amps, and 240 volts (gasoline)
- Parallel capability
- Dual fuel feature so you can run on propane (LPG) too
- Relatively low noise levels of 61 dBA
- Good run time of 19 hours at 25% load (gasoline)
- Good gasoline fuel efficiency
- Less than 3% THD
- Has remote and electric start
- Four GFCI outlets
- 2 years limited warranty
Cons
- Not the most proven generator brand
- Heavy weight of 299 lb (135.6 kg) can be challenging to move
For example, the noise levels of 61 dBA make the AIVOLT 10000 the quietest 10000 watt generator on the market.
Additionally, the electric and remote start make your experience a lot more convenient.
After the setup (and potentially a weather-proof cover) you can turn this dual fuel inverter generator on and off from the comfort of your own house, RV, or party tent.
Even if you decide to run on gasoline, the good run time of 19 hours at 25% load makes it so you can enjoy all that clean inverter power for a long time before refueling.
Whether you actually want to get the AIVOLT 10000 ultimately depends on how much you need the extra power in one dual fuel inverter generator, your risk tolerance, and your budget.
| Brand Model | Power Capacity | Run Time | Quiet Operation | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| AIVOLT 10000 | 10 | 9 | 8.5 | <3% | 7.5 | 9.5 | 8.5 | 5.5 | $$$$$ | Check Price |
