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
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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 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 convenient and easy-to-use electric starter (battery included). It is rated for a noise of 69 dBA (less noisy than background music).

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

The R4400 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<23%).

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

This Rainier generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The dimensions of the Rainier R4400, 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.

As the generator's weight is 111 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). 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 R4400

The R4400's control panel

The R4400's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, which displays voltage, frequency and lifetime hours.

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

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

Regarding its accessories, besides the aforementioned features, the Rainier R4400's box includes the typical documentation and a user manual, letting you start it right off the bat.

Emissions

The Rainier R4400 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, so it is adequate for use 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).

  • Having a dry weight of 111 lbs, the Rainier R4400 belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • As this generator has its lowest possible noise of 69 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • As the R4400 features an autonomy of up to 18 hours at 25% load, it has a higher run time than an average generator of its power range.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency 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 you are concerned with gasoline efficiency, having a fuel consumption of just 0.14 GPH, the Westinghouse iGen4200 is a device you should look out for.

Price comparison

As you can see from this dynamic 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.
