Rainier R4400 Spec Review

Description

Zoom on the Rainier R4400

In summary, the Rainier R4400 is a portable generator especially useful for:

• RV travellers who wish to upgrade their experience to another level
• 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

The Rainier R4400's design includes a gasoline-fueled 212 cc (5.9 hp) Rainier OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3600W and also a peak wattage of 4400W.

The generator is rated for a noise of 69 dBA (less noisy than an office). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included).

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

Since the R4400 has a somewhat high THD (<23%), it is advisable to not use it for the powering of 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

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Rainier generator is RV Ready.

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.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 111 lbs make it incredibly difficult to manually lift and transport. 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

The R4400's control panel

The R4400 and its control panel include a convenient meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

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

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.

Along with the aforementioned features, from an accessory standpoint, the Rainier R4400's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.

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, which makes it suitable 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).

• Since the generator weighs in at a dry weight of 111 lbs, the Rainier R4400 belongs in the expected weight range for devices which can produce between 3500 and 4500 rated watts. 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. For those who are looking for a less noisy device, we suggest the Cummins Onan P4500i. With just 52 dBA, it is one of the most quiet devices in this power range.
• 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 concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 200954, boasting with up to 22 hours.
• 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 is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.22 GPH at a 25% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.14 GPH, may be the right generator for you.

The bottom line

Unlike many websites, we did our best to research each of the specs above. That being said, we are not immune to making the occasional mistake or omission. Should you notice any missing or incorrect values, don't hesitate to suggest improvements so we can address the issue.
