Zoom on the Firman H05754

In a nutshell, the Firman H05754 is a portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • 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

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 H05754 in use

The Firman H05754

The dual-fuel technology of the Firman H05754 allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 5,700W and a starting wattage of 7,125W. If propane-powered, it gives 5,700 rated watts and 7,125 starting watts.

The generator features a simple traditional pull-start mechanism. It is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher).

As for its running time, the H05754, along with its 8 gallons fuel capacity, can run for around 12 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.67 GPH). If propane is used, it can operate for around 5 hours (on a 20 lbs tank - propane consumption around 0.94 GPH).

The powering of sensitive electronic devices with the H05754 is not recommended due to its relatively high THD (<25%).

Outlets

The control panel includes the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

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, as it features a twist-lock L14-30R receptacle, the H05754 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

With its dimensions of L30.2 x W27.5 x H26.3 in, the conventional, open frame design of the Firman H05754 offers stability and allows the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Since the generator weighs 176.5 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). 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 H05754's control panel

The H05754's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman H05754 also comes with some accessories: funnel, tool kit, oil and propane hose are included.

Emissions

The Firman H05754 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor and therefore, can be used in forested areas.

Product Video

The Firman H05754 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H05754 compare to dual fuel generators of similar power (between 5500 and 6500 W).

  • As its weight is 176.5 pounds, the Firman H05754 falls in the expected weight range of the dual fuel devices in the 5500-6500 rated wattage category. If weight is your top priority, one of the champions in this power category is the Pulsar G65BN, weighing just 126 pounds.
  • This generator has a somewhat average expected noise for its type and power range, rated at 74 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Genmax GM7250iEDC with only 63 dBA.
  • Thanks to an impressive running time of around 12 hours at 50% load, the H05754 benefits from one of the highest run times among dual fuel generators of a similar output.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.67 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Genmax GM7250iEDC. With a fuel consumption of as little as 0.45 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 5500-6500W dual fuel generators, the Firman H05754 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
