Zoom on the Firman H05752

In a nutshell, the Firman H05752 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 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 following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Firman H05752 in use

The Firman H05752

The dual-fuel technology of the Firman H05752 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 is rated for a noise of 74 dBA (just slightly more noisy than a shower). Its starting mechanism is based on a simple traditional pull-start mechanism.

With a fuel capacity of 8 gallons, the H05752 can operate for around 12 hours at 50% load using gasoline (fuel consumption around 0.67 GPH), or for around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH) using propane.

As the H05752 has a high THD (<25%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel features the following 6 AC outlets:

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

Even if this Firman generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. Besides, as the H05752 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

The Firman H05752 has the following dimensions: L30.2 x W27.5 x H26.3 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

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). 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

Panel of the Firman H05752

The H05752's control panel

The control panel of the H05752 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.

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

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman H05752, the following accessories are also included: funnel, propane hose, tool kit and oil.

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 and therefore, can be used 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).

  • With its weight of 176.5 lbs, the Firman H05752 is one of the heavier dual fuel generators in the 5500-6500 rated wattage category. In terms of weight, one of the champions in their power range is the Pulsar G65BN, standing at just 126 lbs.
  • This generator has a somewhat average expected noise for its type and power range, rated at 74 dBA. For those who are looking for a less noisy device, we suggest the Genmax GM7250iEDC. With just 63 dBA, it is one of the most quiet devices in this power range.
  • As the H05752 features an autonomy of around 12 hours at 50% load, it has one of the highest run times in comparison to the other dual fuel generators of its power range.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. 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 fuel consumption is your top priority, we suggest to check out the Genmax GM7250iEDC, which has a fuel consumption of only 0.45 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 dual fuel generators, the Firman H05752 is on the average side of the price range.

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

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.
