Zoom on the Rainier R4400DF

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

  • RV travellers looking for even more independence
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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 3600W and a peak wattage of 4400W. When propane-powered, it has 3300 rated watts and 4000 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 powering of sensitive electronic devices with the R4400DF is not recommended due to its relatively high THD (<23%).

Here are a few examples of what this generator could allow you to simultaneously power:Note: Not all of these items may be able to start at the same time. These examples are based on a maximum load of 75 % and on wattage estimates. Use our wattage calculator to find out if this product will be suitable for your needs.

Outlets

The control panel provides the upcoming 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 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 device has been designed for tough environments and demanding 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. Never less, thanks to a wheel kit (⌀8") and a 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 showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

Besides the usual set of documentation and user manual 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, making it usable 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. If weight is your top priority, one of the champions in this power category is the Energizer eZV4500, weighing just 78 pounds.
  • When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 69 dBA is on the noisier side. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500 with only 52 dBA.
  • As the R4400DF features an autonomy of 18 hours at 25% load, it has a higher run time than an average generator of its power range.
  • 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 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 dynamic 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.
