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 H05752 in use

The Firman H05752

With its dual-fuel technology, the powerful and versatile Firman H05752 provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 5,700W along with a peak wattage of 7,125W. While propane-powered, it provides 5,700 rated watts and 7,125 starting watts.

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

As for its running time, the H05752, 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 (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH).

The H05752 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<25%).

Outlets

The control panel includes the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
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, as it features a twist-lock L14-30R receptacle, the H05752 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

The Firman H05752 has a conventional, open frame design, of the following dimensions: L30.2 x W27.5 x H26.3 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

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). Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

The H05752's control panel

The H05752'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.

In addition to this info, when its oil levels are insufficient, you will be informed by the featured light indicator.

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

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman H05752's package also includes these accessories: tool kit, funnel, oil and propane hose.

Emissions

The Firman H05752 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

Product Video

The Firman H05752 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H05752 compare to dual fuel generators of similar power (between 5500 and 6500 W).

  • At a weight of 176.5 pounds, the Firman H05752 places in the expected weight range of the dual fuel generators in the 5500-6500 rated wattage range. In terms of weight, one of the champions in their power range is the Pulsar G65BN, standing at just 126 lbs.
  • 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 Genmax GM7250iEDC, which is one of the least noisy generators in its power range, with a noise rating of just 63 dBA.
  • With a run time of around 12 hours at 50% load, the H05752 has one of the highest run times, compared to its similarly powerful peers.
  • 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. 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 you wish to acquire one of the most gasoline efficient products of this power range, the Genmax GM7250iEDC, with a fuel consumption of 0.45 GPH could be in your good books.

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.
