Zoom on the Rainier R4400DF

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

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • 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

Thanks to its dual-fuel technology, the Rainier R4400DF delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3,600W and a peak wattage of 4,400W. When propane-powered, it has 3,300 rated watts and 4,000 peak watts.

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

Regarding its running time, the R4400DF, with a 4 gallons fuel capacity can operate for up to 18 hours with a full tank of gasoline (fuel consumption around 0.22 GPH). When using propane, it can run for 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

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

Portability

The design of the Rainier R4400DF is a typical, open frame, with the dimensions of L23.5 x W23 x H21 in, offering support and stability and enabling the possibility of raising it above ground level. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 113 pounds. However, this lack of maneuverability is compensated by its wheel kit (⌀8") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Rainier R4400DF

The R4400DF's control panel

The control panel of the R4400DF includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

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. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable 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 dual fuel generators of similar power (between 3500 and 4500 W).

  • With a dry weight of 113 pounds, the Rainier R4400DF finds itself in the expected weight range for dual fuel generators able to produce between 3500 and 4500 rated watts. In terms of weight, one of the champions in their power range is the WEN DF402iX, standing at just 66.1 lbs.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 69 dBA can be considered somewhat noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500DF with only 52 dBA.
  • The R4400DF, offering a run time of up to 18 hours with a full tank at a 25% load, falls within the average autonomy range when compared to its peers. 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.22 GPH at a 25% load. If you wish to further improve in the area of fuel efficiency, the Champion 200988, which boasts with a gas consumption of only 0.16 GPH, may be the right generator for you.

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 cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
