Zoom on the Rainier R4400DF

In summary, the Rainier R4400DF is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • 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 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

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.

With a noise rating of 69 dBA (less noisy than an office), the generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).

With a fuel capacity of 4 gallons, the R4400DF can operate for up to 18 hours using gasoline (fuel consumption around 0.22 GPH), or for up to 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH) using propane.

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

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. The generator is designed for ideal use outdoors and in rough 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

To help you monitor the R4400DF's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.

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

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, 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. 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. 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.

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.
