Zoom on the Rainier R4400DF

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

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Rainier R4400DF in use

The Rainier R4400DF

With its dual-fuel technology, the powerful and versatile Rainier R4400DF provides an output of 120V. While gasoline-powered, it gives a running wattage of 3600W along with a peak wattage of 4400W. While propane-powered, it provides 3300 rated watts and 4000 starting watts.

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

The R4400DF, with a fuel capacity of 4 gallons, reaches a run time of up to 18 hours utilizing gasoline (fuel consumption around 0.22 GPH). Alternatively, it can reach a run time of up to 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH) with propane.

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

Outlets

The control panel features the following 4 AC outlets:

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

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

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. This type of design is ideal for tough environments and heavy outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 113 lbs make it incredibly difficult to manually lift and transport. 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 control panel of the R4400DF includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

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, so it is adequate for use 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 generators of similar power (between 3500 and 4500 W).

  • Having a dry weight of 113 lbs, the Rainier R4400DF belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 69 dBA can be judged as noisy. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Cummins Onan P4500i, whose lowest noise levels reach 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 generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 200914, as it provides up to 22 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator has an estimated fuel consumption of roughly 0.22 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.14 GPH and thus, is one of the most efficient devices in our database.
