5 Quietest propane generators reviewed
People in a hurry can use the overview of the quietest propane generators and the performance table to make a choice.
On the other hand, the detailed reviews of all the options below will likely be helpful for finding the best generator for your situation.
1. A-iPower SUA2000iD – Quietest propane generator
The first four quietest propane generators have the same decibel ratings but since smaller models tend to be less noisy, this A-iPower SUA2000iD gets the top spot.
At the same time, it is important to note that you will likely prefer one of the other options in terms of power capacity, reliability, and price.
There are a decent number of cases where the first A-iPower SUA2000iD customers got did not function as desired.
You may also not like the potential of challenging starts, the somewhat lower amount of power, and the uncertainty about the exact propane consumption.
Pros
- Relatively low noise levels of 52 dB
- A-iPower SUA2000iD offers 1800 starting watts, 1500 running watts, 15 amps, and 120 volts (propane)
- Parallel capability
- Dual fuel means generator can run on gasoline too
- Good run time of 34 hours at 25% load on a 20-lb propane (LPG) tank
- Less than 3% THD
- Light weight of 48 lb (21.8 kg)
- 3 years limited residential and 1 year limited commercial warranties
Cons
- 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
Even if you want a light or budget-friendly quiet propane inverter generator, there are better options than the A-iPower SUA2000iD.
It is worth noting that the A-iPower SUA2000iD is still a decent generator. You could theoretically consider it if you like the brand or stumble upon good deals.
Especially if you want a small propane generator that is easy to carry in and out of the car for camping trips, fishing, car detailing, etc.
However, it is worth mentioning again that while this propane-compatible generator is quiet, it will likely not be the best option for your situation.
| 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 | ? | <3% | 7 | ? | 7.5 | 9 | $$ | Check Price |
2. DuroMax XP2300iH
The DuroMax XP2300iH is better than the A-iPower SUA2000iD in the sense that it offers more power and propane consumption specifics without raising the decibel rating.
At the time, you need to know that the DuroMax XP2300iH has a decent number of technical issues too.
The result is that this is likely another quiet propane generator you want to pass on. However, I’ll go into the positive points of this option too so you can make the decision.
Its lower power output helps with this to some extent but the DuroMax XP2300iH still has a good run time of 38 hours at 25% load on a 20-lb propane (LPG) tank.
Pros
- Relatively low noise levels of 52 dB
- DuroMax XP2300iH offers 2150 starting watts, 1700 running watts, 17.9 amps, and 120 volts (propane)
- Parallel capability
- Dual fuel means generator can run on gasoline too
- Good run time of 38 hours at 25% load on a 20-lb propane (LPG) tank
- 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
A good run time like this can be helpful for power outages where your propane generator needs to keep appliances like a refrigerator going for a long time.
During all this power generation, the CO sensor of the DuroMax XP2300iH helps you make sure there is not too much carbon monoxide buildup around the machine.
And when your power outage (or camping trip, etc.) is over, it is relatively easy to move the weight of 53 lb (24 kg) back to its storage area.
In case something does go wrong with the DuroMax XP2300iH during all this, you can fall back on the three years limited residential and one year limited commercial warranties.
| 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 | 9.5 | Clean THD | 7 | 8 | 7.5 | 8.5 | $$ | Check Price |
3. WEN DF250i
This WEN DF250i is still not the number one most reliable option but it is the first of the quietest propane generators that is really worth considering.
The main reason for this is the budget-friendly price.
However, the low weight and extra watts of the WEN DF250i are positive points too.
These make it easier to get the propane generator in and out of position and offer just a bit more value.
Pros
- Relatively low noise levels of 52 dBA
- WEN DF250i offers 2250 starting watts, 1800 running watts, 18.7 amps, and 120 volts (propane)
- Parallel capability
- Dual fuel means generator can run on gasoline too
- Run time of 17.5 hours at 50% load on a 20-lb propane (LPG) tank
- 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
Additionally, the nice run time of 17.5 hours at 50% load makes it so the WEN DF250i can run things like a refrigerator overnight.
Something you do want to know is that there are not that many reviews for the WEN DF250i (yet).
Customers tend to receive WEN generators well but there is still a small risk that this model has issues that are not in the specifications list.
So if you don’t necessarily need the most reliable option and/or want to save some money in the short term, the WEN DF250i could be the right quiet propane generator for you.
