2. DuroMax XP2200EH Portable Generator

Runner Up

The honorable second place belongs to quiet DuroMax.

It’s a well-designed, compact, and lightweight generator which is great for easy portability and outdoor use.

It has all the basic features we look for in a good generator which are an easy push-button start, dual fuel, option for having a parallel connection, and clean power for sensitive electronics.

The generator has a 4-stroke air-cooled engine which runs extremely efficiently on both Gas and Propane.

We can easily switch between gas and propane by turning the fuel selection dial.

The DuroMax XP2200EH Portable Generator has a run time of 6.8 hrs with gasolene at 1/2 load and 19.1 hrs with Propane at 1/2 load. 

It is clear that the generator is designed with portability and compactness as top priorities as the gasoline fuel tank can hold only 1.2 gallons.

The device has a built-in idle control mechanism that automatically lowers the engine RPM when there is no load, thus saving more fuel. This is great in a situation where your power requirement could be intermittent.

A low oil shut-off sensor is also provided which basically shuts-off the engine when it detects that the oil is too low thus helping you avoid costly engine repair work.

The DuroMax XP2200EH Portable Generator has a 5V 1.5A USB port and two 120V GFCI outlets. You can also add more power by connecting a similar generator through the parallel connection port.

Having been designed as a compact and fully covered enclosure, the device is really good at attenuating the noise generated during operation.

It is found to generate a low noise of around 61 dBA which is considerably quieter for any regular portable generator.

The DuroMax XP2200EH Portable Generator has a clear advantage over its competitors in terms of portability and performance although it missed out on the various output ports provided by the Champion 3400-Watt Portable Inverter Generator. 

Pros

  • Great Build
  • Very Efficient

What To Consider When Buying A Silent Propane Generator?

Power Rating

Every silent propane generator is sold based primarily on the power rating. Now it is important to note the caveat in this. 

Most manufacturers use the peak power that a generator is able to provide in the name of the product. This might be a little misleading for some since the actual continuous running power output is a bit lower than that.

For example, the Champion 3400 Watt generator has a peak power output of 3400W but the actual power output that you’ll get continually is 3100W.

Again if you are looking for a propane generator, you must keep in mind that you’ll have to look specifically for the power output rating of the device for propane as fuel.

In the case mentioned above, the Champion 3400 watt generator actually provides a continual power output of 2790 Watts. Hence you need to check the manufacturer’s specifications thoroughly before making a decision.

And of course, in order to do this, you must work out your power requirement when using the generator.

Let’s say your requirement is,

1) Refrigerator – 500W

2) Lights – 100W

3) Water heater – 700W

So your total requirement will come to1300W. Now you must look for a generator that can provide 1300W while running at roughly 80% of its capacity which will be around 1625W.

Parallel Output

The parallel output is an amazing feature that lets you connect two generators to increase the total power output. This is very handy if your buddy has a similar generator and you are in urgent need of surplus power for a house party.

Although the generator that you’re desiring might or might not have this feature, it is usually not mentioned clearly in the marketing material. 

So you’ll have to study the manufacturer’s specification to find out whether the device can be connected parallelly to another generator.

Although this is very useful, you need not worry too much about it if you determine that you won’t be facing such a power requirement in the future.

EPA & CARB Compliance

EPA stands for the United States Environmental Protection Agency and CARB stands for California Air Resources Board. 

Propane or LPG as a fuel for power generators is becoming more popular every day for two reasons, one, they are environment friendly, and second, they make less noise during operation. Nevertheless, any generator will release a bit of harmful gases when burning fuel.

Therefore, it is extremely important that you purchase a generator that has obtained the certificate of compliance from EPA and CARB which have strict guidelines regarding environmental pollution control.

Clean Power

When connecting sensitive electronics to the power supply provided by the generator, there is a high risk of damage due to electrical fluctuation.

The measure of such fluctuation is called the THD%. THD stands for Total harmonic distortion and the lower the value the cleaner the power and safer it is to connect sensitive electronic devices.

Always look for a generator that has 5% or less THD if you will be connecting devices like a Smartphone or a Laptop during the generator usage.

Noise

Manufacturers usually mention the noise generated by the generator in dBA. dBA is the noise level measured at a distance of 23 feet from the generator. The lower the dB value, the quieter your generator will be. 

To get an idea of how much a dBA level feels like,

30dBA – Whisper

50dBA – Moderated rainfall

60dBA – Normal Conversation

70dBA – City Traffic

80dBA – Hair Dryer

120dBA – Jet-plane take-off

You have to keep in mind that the actual noise produced by the generator depends also on whether the device is placed in an open space and whether it has been serviced properly.

An ill-maintained generator is not only noisy but also deteriorates in performance over time.
