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 sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- RV travellers wishing to enhance their freedom and nomad lifestyle
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 9500W and a peak wattage of 12000W. When propane-powered, it has 8550 rated watts and 10800 peak watts.
The generator is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher). Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant electric starter (battery included).
As for its running time, the R12000DF, along with its 6.6 gallons fuel capacity, can run for up to 17 hours with a full tank filled with gasoline (fuel consumption around 0.55 GPH). If propane is used, it can operate for up to 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH).
The quite high THD (<23%) of the R12000DF makes it unsuitable for powering sensitive electronic devices.
The control panel provides the upcoming 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, 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.
The design of the Rainier R12000DF is a typical, open frame, with the dimensions of L29 x W24.5 x H24 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy 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. Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
The control panel of the R12000DF includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).
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. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor and therefore, can be used 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.
