Description
Zoom on the Firman H08051
In a nutshell, the Firman H08051 is a portable generator mostly geared towards:
- Food truck owners who do not wish to see their business interrupted under any circumstances
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals who want to ensure that a power failure will not prevent them from working
- RV travellers wishing to enhance their freedom and nomad lifestyle
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Firman H08051
Thanks to its dual-fuel technology, the Firman H08051 delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 8,000W and a peak wattage of 10,000W. When propane-powered, it has 7,250 rated watts and 9,050 peak watts.
With a noise rating of 74 dBA (just slightly more noisy than a dishwasher), the generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included).
The running time of the H08051, with its 8 gallons fuel capacity, can reach around 12 hours at 50% load on a full tank of gasoline (fuel consumption around 0.67 GPH). With propane, it can reach around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH).
The quite high THD (<25%) of the H08051 makes it unsuitable for powering sensitive electronic devices.
Outlets
The control panel features the following 5 AC outlets:
If you own an RV with a 50-amp service, you can consider this Firman 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, due to the featured twist-lock L14-30R receptacle, the H08051 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
Portability
The dimensions of the Firman H08051, which are L30.2 x W27.5 x H26.3 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
As the generator's weight is 212 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed 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 you voltage, frequency and lifetime hours.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
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).
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman H08051 also is packed along with the following accessories: oil, funnel, tool kit and propane hose.
Emissions
The Firman H08051 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 and therefore, can be used in forested areas.

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).
- As its weight is 212 pounds, the Firman H08051 falls in the expected weight range of the dual fuel devices in the 7500-8500 rated wattage category. If weight matters to you, one of the champions in this power range is the Cummins Onan P9500df with only 194 pounds.
- If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 74 dBA can be considered somewhat noisy. If you are concerned with noise, check out the Genmax GM9000iED, which is one of the least noisy generators in its power range, with a noise rating of just 62 dBA.
- The H08051 provides one of the highest run time among similarly powerful dual fuel devices, reaching around 12 hours at 50% load.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator, with an estimated fuel consumption of just 0.67 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Pulsar PG10000B16, which has a fuel consumption of only 0.55 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from this interactive chart, when compared to other 7500-8500W dual fuel generators, the Firman H08051 is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.

Unlike many websites, we did our best to research each of the specs above. That being said, we are not immune to making the occasional mistake or omission. Should you notice any missing or incorrect values, don't hesitate to suggest improvements so we can address the issue.
* Propane runtime is our own estimation, based on a 20 lbs tank and NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs of propane = 1 gal of gasoline.
