Quick Comparison Table
Must Have Features of The Most Efficient Propane Generators
Propane generators must have certain features to be considered efficient and worth their price.
Let me share the most important of these features with you in case you want to find the most efficient propane generator on your own.
If you want to find an efficient propane generator, make sure it has an efficient motor that produces the most wattage while using the least amount of propane.
This way, you can be certain that you are investing in a powerful and efficient generator.
In terms of wattage, I believe the best inverter generator for camping should have at least 2,000 starting watts and 1,500 running watts, which is enough power to juice your most important electronics.
What good is a propane generator that is too large and bulky?
Yes, it will most likely be powerful because it will house a larger motor, but it will be extremely difficult to maneuver.
That’s why I always look for propane generators that are either compact and portable or large but have handles and wheels for easy transportation (you’ll get the best of both worlds this way).
What better way to ensure that your propane powered generator has a longer runtime than by purchasing one with a large propane fuel tank?
After all, the larger the fuel tank, the longer the runtime, right?
Yes, but you should also consider how large and heavy the propane generator will be.
There is, in my opinion, a sweet spot regarding tank size that will provide enough runtime and a good level of portability, which is around 2 gallons.
Anything larger will need to have wheels and handles to make it easier to move around.
Voltage is the electrical current pressure that powers devices and high amperage power tools when they are plugged into an outlet.
If your generator does not provide a steady stream of voltage, you are putting your expensive and sensitive electronics at risk.
This is why I advise people to purchase propane generators that provide a steady stream of voltage. Otherwise, you’ll live to regret it.
Let’s face it: nothing is more annoying than a noisy generator.
Unfortunately, most generator motors are extremely loud when in full operation.
However, there are some that have advanced technologies aimed at reducing as much noise as possible when in full operation.
In that case, I’d say the most efficient generator should be able to operate in a noise range of 50 to 70 decibels.
Frequently Asked Questions
In the following section of this article, I will attempt to answer some frequently asked questions about the most efficient propane generator.
What are the pros and cons of a propane generator?
Let’s start with the advantages of a propane generator:
- It emits fewer harmful combustion gases to the environment than gasoline. As a result, it is more environmentally friendly
- Because propane has no expiration date, it is much more convenient
Now for the drawbacks:
- Propane generators are significantly louder than gasoline generators. Don’t ask me why; they simply are
- They are more expensive
- They can be a bit harder to repair because they are not that popular and due to their more complex internal components
Are propane generators more efficient than gas generators?
Propane generators are inefficient compared to gas generators. They generate fewer BTUs per gallon of propane than gas generators do.
They are, however, more environmentally friendly than gas generators because they emit fewer harmful gases than gasoline-powered generators.
Are propane generators cheaper than gas generators?
This is a difficult question.
Yes, propane is technically less expensive than gas. As a result, running a propane generator is less expensive than running a gas generator.
However, propane generators cost more than gas generators.
To summarize, propane generators will save you money in the long run, but you will have to spend a little more money upfront.
Will a generator run longer on propane?
This is heavily dependent on the technology of each generator, as it is in charge of getting the most out of the propane stored in the fuel tank.
What I can tell you is that most portable generators will run for about 8 hours on a medium load. But again, you should check the specifications of your next propane-powered generator.
How long will a generator run on a 20lb tank of propane?
A propane generator with a 20lb fuel tank, in my experience, will run for 5 to 8 hours on a medium load.
Again, this will be determined by the technology of each propane generator as well as the load that you subject your propane generator to.
