One disadvantage of this generator is its hefty price tag.

10. Green-Power America GPG10000EW

Rainier R12000DF

When buying a 10000 watt generator, you should ideally go with a dual fuel unit.

They offer numerous benefits.

First, running a generator on propane is cheaper in the longer-term than using gasoline.

That’s especially the case with large 10000 watt units as they consume more fuel.

They also offer you more flexibility in terms of the fuel choice and allows you to run the generator for longer.

Based on our comparative analysis, Rainier R12000DF is one of the best hybrid 10000 watt units out there.

It has a  457cc OHV 4 stroke engine providing up to 17 hours of continuous runtime at a 25% load.

It delivers 12500 surge watts and 9500 running watts when running on gasoline.

On propane, the portable generator provides 10800 starting watts and 8550 running watts.

The generator comes with all standard electric outlets and receptacles. These include:

  • 2 x 5-20R 120V AC 20A household outlets
  • 1 x L5-30R 120V 30A outlet
  • 14-50R 120/240V 50A outlet

The control panel has also got a 1L14-30R 120V 30A transfer switch ready outlet making this generator a viable choice for home backup power supply.

The generator has also got a low oil shutdown mechanism.

It also features an overload protection alarm that helps prevent damage to the engine.

Another good thing about this generator is that it’s both CARB and EPA certified.

The generator is 100% legal to use in all US states and is a viable choice for California residents.

10000 watt generators are usually noisy beasts. You certainly can’t expect them to run noiselessly, regardless of the load.

However, when preparing our list of 10 best 10000 watt generators, we examined the noise levels too. We were trying to find a generator that not only performs well but also minimizes the disruption caused by its loud engine.

We have found the Rainier R12000DF to be on the quieter side.

While not as quiet as the unrivaled Honda generators, the RD12000DF makes approx. 72 dB of noise at 25% load.

That is undoubtedly a better score than in case some of the older and bulkier contractor generators.

Overall, it is a quality 10000 watt generator and a good choice both for home and industrial use.

Pros
  • Long runtime

  • Reasonably quiet

  • Low price tag

Cons
  • Heavy
