At maximum power load the generator can run for up to 4.5 hours.
Running this unit at half load should get you around 7 hours of continuous operation.
One problem with generators of this size is that they are usually very loud.
Since Honda is known for manufacturing some of the quietest generators in the market like the super-popular EU2200i, we were curious to see if they managed to minimize the noise level in their largest generators too.
The EB10000 produces around 73 dB at maximum power load.
This industrial generator is remarkably silent for its size and is quieter than most of its competitors in this wattage range.
One disadvantage of this generator is its hefty price tag.

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 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 operation at a 25% load.

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.
