This generator 7100 starting Watts and 5700 running watts for both gasoline and LP with a reliable recoil start system. (source: Firman (opens in a new tab))

Zoom on the Firman H05752

In summary, the Firman H05752 is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • 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 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 5700W and a starting wattage of 7125W. If propane-powered, it gives 5700 rated watts and 7125 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.

Regarding its running time, the H05752, with a 8 gallons fuel capacity can operate for around 13 hours at 50% load with a full tank of gasoline (fuel consumption around 0.62 GPH). When using propane, it can run for around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH).

The quite high THD (<25%) of the H05752 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel provides the upcoming 6 AC outlets:

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

This Firman generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, because the H05752 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

With its dimensions of L29.8 x W27.5 x H26.1 in, the conventional, open frame design of the Firman H05752 offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 176 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, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.

Features

Panel of the Firman H05752

The H05752's control panel

The H05752's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with 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 includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman H05752 also comes with several accessories, including: tool kit, oil, propane hose and funnel.

Emissions

The Firman H05752 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 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 generators of similar power (between 5500 and 6500 W).

  • Weight-wise, the Firman H05752 has only 176 lbs, which renders it one of the lighter generators which produce 5500 to 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.
  • Since the generator's noise is rated at 74 dBA, it has the roughly average expected noise for a device of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU7000iS with only 52 dBA.
  • The H05752 provides a higher run time than similarly powerful devices, reaching around 13 hours at 50% load. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Cat RP5500, reaching around 15 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator reaches an estimated fuel consumption of 0.62 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Lifan ESI 7000iER-EFI, which has a fuel consumption of only 0.38 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 H05752 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.

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.
