Fuel-Efficient: DuroMax XP2000EH
- Fuel efficient – the Eco Mode and idle control
- Able to double the power output if wanted - parallel compatibility
- Easy to carry around – lightweight & a handle
- No transportation wheels
- The parallel kit is sold separately
While all inverter generators are fuel-efficient, we find the DuroMax XP2000EH makes it to the next level. It emphasizes an Eco Mode for lowering its idle speed to the minimum propane consumption.
In addition to that, it has idle control to lower its RPMs when less power is required, and as the result, it lasts up to 6.5 hours at ½ load.
Another big bonus is its parallel compatibility, which allows for bridging two XP2000EH generators at a time for higher power output.
You might see that this unit doesn’t have transportation wheels (which is a pity!), in turn, it highlights a handle and the total weight is only 47 pounds. It’s easy to lift up and carry around – perfect for camping, tailgating, or emergency power.

How To Choose The Best Quiet Propane Generator?
Noise level
When you’re seeking a quiet generator, the noise level should always be the highest priority. The noise level is measured in dB, the higher the value, the nosier the machine.
There isn’t a generator that’s completely quiet, but you can find a machine that makes noise lower than the conversational level. As a rule of thumb, a noise rating between 55 and 65 dBA is considered quiet for a propane generator.
Power output
No matter how quiet a generator is, you still need enough output power to run your tools and appliances. The more power produced, the more appliances you can run.
However, you need to first figure out how much power you need by taking into account the essential tools and appliances to use. Then, when shopping, you just have to find the power you need or higher.
For example, a generator as a home backup power source should produce about 8000W to run appliances for a good amount of time.
Runtime
The runtime refers to the duration that a generator can run on a certain amount of fuel, often measured at 25 or 50 percent of the load. A generator with a low runtime tends to consume less fuel, but you should look at this indicator on the machine and choose the one that fits your needs.
