Zoom on the Firman H05754

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

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • 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 5700W and a starting wattage of 7125W. If propane-powered, it gives 5700 rated watts and 7125 starting watts.

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

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 quite high THD (<25%) of the H05754 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features the upcoming 6 AC outlets:

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

While this Firman generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, due to the featured twist-lock L14-30R receptacle, the H05754 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

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. This type of design is ideal for tough environments and heavy outdoor use.

As the generator's weight is 176.5 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

Panel of the Firman H05754

The H05754's control panel

The H05754 and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman H05754, the following accessories are also included: propane hose, funnel, tool kit and oil.

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, which makes it suitable for use 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 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 devices in the 5500-6500 rated wattage category. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar G65BN, with a dry weight of just 126 pounds.
  • As this generator can emit noise as low as 74 dBA, it finds itself in the average expected noise for this kind of power. If you are concerned with noise, check out the Honda EU7000iS, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Since the H05754 boasts with a run time of around 12 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. 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 Westinghouse WGen5500, 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.67 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the A-iPower SUA7000L, which has a fuel consumption of only 0.36 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 5500-6500W 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.
