Zoom on the Firman H08051
In short, the Firman H08051 is a portable generator adequately designed for:
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals in need of safely powering high-intensity work or lighting equipment
- RV travellers wishing to enhance their freedom and nomad lifestyle
Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.
Power & Run Time
The Firman H08051
With its dual-fuel technology, the powerful and versatile Firman H08051 provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 8,000W along with a peak wattage of 10,000W. While propane-powered, it provides 7,250 rated watts and 9,050 starting watts.
The generator is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher). Its starting mechanisms include a manual recoil starter system and a convenient and efficient electric starter (battery included).
Regarding its running time, the H08051, with a 8 gallons fuel tank, can operate for around 12 hours at 50% load with a full gasoline tank (with fuel consumption estimated at around 0.67 gallons per hour). It also offers around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH) of operation when using propane.
Considering its high Total Harmonic Distortion (THD) of less than 25%, it is not recommended to rely on the H08051 for powering sensitive electronic devices.
Outlets
The control panel features the upcoming 5 AC outlets:
If your RV requires a 50-amp service, consider this Firman unit RV-ready, as it includes a 14-50R outlet. In addition, the H08051's twist-lock L14-30R receptacle makes it transfer switch ready, enabling hassle-free connection to your breaker box for powering your home during outages.
Portability
With a size of L30.2 x W27.5 x H26.3 in, the Firman H08051 features an open frame design, providing stability and simplified maintenance access to components, enhancing air circulation. The design is ideal for rough environments and demanding outdoor use.
With a weight of 212 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. However, the constrained maneuverability is addressed with the assistance of its wheel kit (⌀10") and its folding handle, allowing for easy shifting once the generator is placed on the ground.
Features
The H08051's control panel
To help you monitor the H08051's status and activity, its control panel is equipped with a convenient meter, showing voltage, frequency, and lifetime hours metrics.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
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).
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman H08051's package also includes these accessories: propane hose, tool kit, funnel and oil.
Product Video
The Firman H08051 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman H08051 compare to dual fuel generators of similar power (between 7500 and 8500 W).
- At 212 lbs dry, the Firman H08051 is consistent with the standard weight profile for dual fuel devices ranging from 7500 to 8500 rated watts. In terms of weight, one of the champions in their power range is the Pulsar PGL9000BCO, standing at just 149 lbs.
- With noise emissions rated as low as 74 dBA, this generator falls within the typical noise range expected for devices of similar type and power. If you wish to prioritize minimal noise, the DuroMax XP9500iH stands out as one of the quietest options among generators of similar power, with a rating of 61 dBA.
- At 50% load, the H08051 achieves one of the longest run times compared to dual fuel devices of similar power, sustaining operations for around 12 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. With a fuel consumption rate around 0.67 GPH (gallon per hour) at 50% load, this generator is one of the more fuel-efficient models within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.59 GPH, the Powerhorse s10500id is a device you could look out for.
Price comparison
As you can see from these interactive charts, when compared to other 7500-8500W dual fuel generators, the Firman H08051 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

User Reviews
Overall a nice generator. Did the job for me for 10 straight hours when I lost power. I was happy to find a generator with a 50 amp outlet on it. That feature is hard to find anymore.
My Firman dual fuel failed when the valve stem broke and lodged in the cylinder . It was a right off . I had it for less than a year . Customer service would not honor the warranty because they said I had not done ongoing servicing by adjusting valve settings and not doing clearance checks on the rocker arms and I could not prove I had done proper oil changes . Kiss goodbye to $1600
Not impressed, only got to run it 3 hrs, flip the breaker nothing happens, installed new breaker still dont work !
