From emergency backup use to camping and tailgating, this is the perfect choice as your go-to power supply for open gatherings, outdoor activities, and home use alike. For all that life brings you, the R4400 will keep you connected whether you’re staying in or venturing out.

Zoom on the Rainier R4400

In a nutshell, the Rainier R4400 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 able to use the most necessary devices in their household, even during a blackout

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 R4400 in use

The Rainier R4400

The Rainier R4400's engine, 212 cc (5.9 hp) Rainier OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3600W and reaches a peak wattage of 4400W.

The generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 69 dBA (less noisy than background music).

With a fuel capacity of 4 gallons, the R4400 may run for up to 18 hours with a full tank (fuel consumption around 0.22 GPH).

The powering of sensitive electronic devices with the R4400 is not recommended due to its relatively high THD (<23%).

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

With its dimensions of L23.5 x W23 x H21 in, the conventional, open frame design of the Rainier R4400 offers stability and allows the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

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 111 lbs. However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Rainier R4400

The R4400's control panel

The R4400'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.

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

Regarding its accessories, besides the aforementioned features, the Rainier R4400's box includes the typical documentation and an owner's manual (opens in a new tab), letting you start it right off the bat.

Emissions

The Rainier R4400 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 and thus, may be used in forested areas.

The Rainier R4400 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Rainier R4400 compare to generators of similar power (between 3500 and 4500 W).

  • As its weight is 111 pounds, the Rainier R4400 falls in the expected weight range of the 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 GN400i, 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 devise of a similar running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 52 dBA.
  • The R4400, falls within the average autonomy range compared to generators of a roughly same power, with a run time of up to 18 hours at a 25% load and a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200954, reaching up to 22 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.14 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Rainier R4400 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
