Description
Zoom on the Firman H05751
In summary, the Firman H05751 is a portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and festivals
- Food truck owners who do not wish to see their business interrupted under any circumstances
- Homeowners in need of an emergency backup power for their essentials
- Professionals who want to ensure that a power failure will not prevent them from working
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Firman H05751
With its dual-fuel technology, the powerful and versatile Firman H05751 provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 5700W along with a peak wattage of 7125W. While propane-powered, it provides 5700 rated watts and 7125 starting watts.
The generator is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher). Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included).
With a fuel capacity of 8 gallons, the H05751 can operate for around 13 hours at 50% load using gasoline (fuel consumption around 0.62 GPH), or for around 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH) using propane.
Since the H05751 has a somewhat high THD (<25%), it is advisable to not use it for the powering of sensitive electronic devices.
Outlets
The control panel features the upcoming 6 AC outlets:
Even though this Firman generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, because the H05751 is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
Portability
The design of the Firman H05751 is a typical, open frame, with the dimensions of L29.8 x W27.5 x H26.1 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.
Since the generator weighs 196 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). However, this lack of maneuverability is compensated by its wheel kit (⌀10") and its folding handle, with which you can conveniently shift it, once it's on the ground.
Features
The H05751's control panel
The H05751's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, which displays voltage, frequency and lifetime hours.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman H05751 also comes with some accessories: oil, propane hose, funnel and tool kit are included.
Emissions
The Firman H05751 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, so it is adequate for use in forested areas.

The Firman H05751 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman H05751 compare to generators of similar power (between 5500 and 6500 W).
- With a dry weight of 196 pounds, the Firman H05751 finds itself in the expected weight range for generators able to produce between 5500 and 6500 rated watts. Regarding dry weight, one of the champions in the same power range is the Lifan LF7250, with a dry weight of only 140 lbs.
- Because this generator emits noise as low as 74 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU7000iS, whose lowest noise levels reach just 52 dBA.
- As the H05751 features an autonomy of around 13 hours at 50% load, it has a higher run time than an average generator of its power range. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Cat RP5500, with around 15 hours.
- While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. As this generator uses an estimated 0.62 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.38 GPH, the Lifan ESI 7000iER-EFI is a device you should look out for.
Price comparison
As you can see from this interactive chart, when compared to other 5500-6500W generators, the Firman H05751 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.
