For all that life brings you, the R4400DF will keep you connected whether you’re staying in or venturing out.

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

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

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.

The generator is rated for a noise of 69 dBA (less noisy than an office). Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use 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).

As the R4400DF has a relatively high THD (<23%), it is not recommended to use it to power 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

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Rainier generator is RV Ready.

Portability

The dimensions of the Rainier R4400DF, which are L23.5 x W23 x H21 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 113 lbs. 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 control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

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

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

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 generators of similar power (between 3500 and 4500 W).

  • Since the generator weighs in at a dry weight of 113 lbs, the Rainier R4400DF belongs in the expected weight range for devices which can produce between 3500 and 4500 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • This generator, with its lowest possible noise rated at 69 dBA falls into the more noisy category, compared to other devise of a similar running wattage. For those who are looking for a less noisy device, we suggest the Cummins Onan P4500i. With just 52 dBA, it is one of the most quiet devices in this power range.
  • Since the R4400DF boasts with a run time of up to 18 hours at 25% load, it can be safely judged as one of the devices with the highest run time among those of a comparable output.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.22 GPH (gallon per hour) at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.14 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W 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.
