Zoom on the Rainier R4400DF

In a nutshell, the Rainier R4400DF is a portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Rainier R4400DF in use

The Rainier R4400DF

The dual-fuel technology of the Rainier R4400DF allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3,600W and a starting wattage of 4,400W. If propane-powered, it gives 3,300 rated watts and 4,000 starting watts.

At a noise rating of 69 dBA (less noisy than a normal conversation), this generator can be started via a simple traditional pull-start mechanism, or a simple and elegant electric starter (battery included).

The running time of the R4400DF, with its 4 gallons fuel capacity, can reach up to 18 hours on a full tank of gasoline (fuel consumption around 0.22 GPH). With propane, it can reach up to 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH).

The quite high THD (<23%) of the R4400DF makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel includes the following 4 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120V 30A (TT-30R) receptacle

This Rainier generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The Rainier R4400DF has the following dimensions: L23.5 x W23 x H21 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 113 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Nevertheless, thanks to its wheel kit (⌀8") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Rainier R4400DF

The R4400DF's control panel

The R4400DF's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Rainier also included a propane hose in the R4400DF's packaging.

Emissions

The Rainier R4400DF is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

The Rainier R4400DF versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Rainier R4400DF compare to dual fuel generators of similar power (between 3500 and 4500 W).

  • As its weight is 113 pounds, the Rainier R4400DF falls in the expected weight range of the dual fuel devices in the 3500-4500 rated wattage category. Regarding dry weight, one of the champions in the same power range is the WEN DF402iX, with a dry weight of only 66.1 lbs.
  • This generator, with its lowest possible noise rated at 69 dBA falls into the more noisy category, compared to other devices of a similar running wattage. If you are concerned with noise, check out the Westinghouse iGen4500DF, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Offering up to 18 hours of running time on a full tank at 25% load, the R4400DF is within the average autonomy range of similarly powerful dual fuel generators. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Firman WH03662OF, which is able to run for up to 25 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.22 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Champion 200988, with a fuel consumption of 0.16 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W dual fuel generators, the Rainier R4400DF is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
