Zoom on the Rainier R12000DF
In summary, the Rainier R12000DF is a powerful portable generator especially useful for:
- Prudent homeowners who want a backup power source in case of a power outage
- Professionals who want to ensure that a power failure will not prevent them from working
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- RV travellers wishing to enhance their freedom and nomad lifestyle
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
Thanks to its dual-fuel technology, the Rainier R12000DF delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 9,500W and a peak wattage of 12,000W. When propane-powered, it has 8,550 rated watts and 10,800 peak watts.
Enjoying a noise rating of 74 dBA (just slightly more noisy than a shower), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included).
The running time of the R12000DF, with its 6.6 gallons fuel capacity, can reach up to 17 hours on a full tank of gasoline (fuel consumption around 0.55 GPH). With propane, it can reach up to 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH).
As the R12000DF has a high THD (<23%), it is not recommended to use it to power sensitive electronic devices.
The control panel features 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. Its L5-30R receptacle can also be used for a simple RV connection with an L5-30P to TT-30R adaptor. In addition, because the R12000DF is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
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.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 196 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit (⌀10") and its folding handle, which will ease its displacement, once it is on the floor.
The R12000DF and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
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.
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, which makes it suitable for use in forested areas.
The Rainier R12000DF versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Rainier R12000DF compare to dual fuel generators of similar power (between 9000 and 10000 W).
- As far as its dry weight is concerned, the Rainier R12000DF weighs just 196 pounds and thus, it is one of the lightest 9000 to 10000 rated wattage dual fuel generators.
- Since the generator's noise is rated at 74 dBA, it has the roughly average expected noise for a device of similar type and power. If noise emissions are one of your priorities, you may be interested in the A-iPower SUA12000ED, one of the least noisy generators similarly powerful as this one, rated for 69 dBA.
- The R12000DF provides one of the highest run time among similarly powerful dual fuel devices, reaching around 12 hours at 50% load.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator, with an estimated fuel consumption of just 0.55 GPH (gallon per hour) at 50% load, is one of the most fuel efficient generators, for the previously mentioned wattage range.
The bottom line
- GFCI Outlets
