  • 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.

At a noise rating of 69 dBA (less noisy than a normal conversation), this generator can be started via a conventional pull-start mechanism, or 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 powering of sensitive electronic devices with the R4400DF is not recommended due to its relatively high THD (<23%).

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

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

Portability

The Rainier R4400DF has a conventional, open frame design, of the following dimensions: L23.5 x W23 x H21 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

As the generator's weight is 113 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀8") and its folding handle, once it is placed on the ground.

Features

Panel of the Rainier R4400DF

The R4400DF's control panel

The R4400DF and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring 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. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may 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. If weight is your top priority, one of the champions in this power category is the WEN DF402iX, weighing just 66.1 pounds.
  • 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.
  • The R4400DF, falls within the average autonomy range compared to dual fuel generators of a roughly same power, with a run time of up to 18 hours at a 25% load and a full tank. 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.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator reaches an estimated fuel consumption of 0.22 GPH (gallon per hour) at a 25% load, making it average, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Champion 200988, which has a fuel consumption of only 0.16 GPH and thus, is one of the most efficient devices in our database.
