Parallel Capable: Pulsar PG2200BiS
- The most economical option with a parallel kit
- Ultra-convenient – USB outlets
- Safe to use – feature low oil shutdown & low oil indicators & meet CARB, EPA, CSA standards
- Wish there were more outlets
When it comes to dual-fuel generators for RVs, camping, or other outdoor activities, it’d be better if the unit is parallel capable for even more power output if needed.
The thing is this extra function comes at a cost.
The average price ranges for a dual-fuel parallel-capable generator without a parallel kit included are around $550-$700 while those models with an enclosed kit are usually above $1000.
That’s why we are pleasantly surprised that the Pulsar PG2200BiS not only includes a parallel kit in the package but also retains its price tag at a highly competitive range.
Moreover, it strikes just the right balance of power with consistent performance, ease of use, and quality, with an emphasis on low oil auto-shutdown, low oil indicator, and a 1-year warranty. What else to ask?

Aside from a manual start, it features an electric start that can be easily operated by the push of a button.
It also provides the user with a one-spot control panel where they can easily track and manage different indicators. There come various outlets (including a 120V 30A RV port and two USB adapters) for extra convenience.

How To Choose The Quiet Dual Fuel Generator?
Noise Level
The measuring unit of generators’ noise levels is decibels (dB or dBA).
Our goal at the current is to find out the quietest dual-fuel generator but still powerful enough to fit your power needs. Dual-fuel generators create noise ranges of 50-90dB, based on the power output, fuel used (propane is quieter than gasoline), and the machine size.
To help you easily find out the acceptable noise range created by generators, here are the decibel ratings of some popular sounds:
- Motorcycle: 95-110dB
- Hairdryer: 70-90dB
- Normal two-person conversation: 60dB
- Refrigerator: 50dB
Conventional dual-fuel generators commonly work at 65-70dB while inverter models create noise ranging from 50-60dB.
Power Output
The measuring unit of the power output of generators is watts (W).
There are two related specifications you need to know – starting wattage (means the max quantity of watts provided by a generator at any one time) and running wattage (means the average quantity of watts created when in use).
These two numbers are usually different between gasoline and propane (gasoline is more powerful than the other).
Due to the functionality and size of the dual-fuel generator, the power output ranges from 1,000-12,000W.
You should determine your power needs before choosing the right generator’s power output. Don’t go for one that is far beyond your needs because the more powerful dual-fuel generators will make louder noise.

FAQs
Is a dual fuel generator worth it?
Yes, it is. Dual-fuel generators are cheaper, easier to ignite (especially during the winter), and more effective than gas-powered ones.
Is it cheaper to run a generator on gas or propane?
It is cheaper to run a generator on propane because this fuel has a lower energy density.
How long will a generator run on 100 gallons of propane?
It depends on the generator size and the load percentage. For example, on 100 gallons of propane at full load, a 12,000W generator can last 36 hours while a 7,000W one lasts 66 hours.
Will a generator run longer on gas or propane?
Propane generators are less efficient than gas models because propane makes fewer BTUs/gallon.
Are propane generators quieter than gas?
Yes, they are because this fuel is clean-burning.
Conclusion
We know that, with so many choices in the market, it’s challenging to choose a quiet dual-fuel generator that also meets your power needs and other requirements. Through this article, our team hopes that you can hone in on the right one for you at the best price. Thanks for reading!
