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 R12000DF

With its dual-fuel technology, the powerful and versatile Rainier R12000DF provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 9500W along with a peak wattage of 12000W. While propane-powered, it provides 8550 rated watts and 10800 starting watts.

At a noise rating of 74 dBA (just slightly more noisy than a dishwasher), this generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included).

The R12000DF, with a fuel capacity of 6.6 gallons, reaches a run time of up to 17 hours utilizing gasoline (fuel consumption around 0.39 GPH). Alternatively, it can reach a run time of up to 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH) with propane.

Since the R12000DF 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 5 AC outlets:

If you own an RV with a 50-amp service, you can consider this Rainier unit as RV-ready, as it features a 14-50R outlet. In addition, as it features a twist-lock L14-30R receptacle, the R12000DF is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The Rainier R12000DF has a conventional, open frame design, of the following dimensions: L29 x W24.5 x H24 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Since the generator weighs 196 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

The R12000DF's control panel

The R12000DF's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours.

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

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

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 R12000DF's packaging.

Emissions

The Rainier R12000DF 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, making it usable in forested areas.
