Zoom on the Firman H05753

In summary, the Firman H05753 is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • 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 in need of an emergency backup power for their essentials

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 H05753 in use

The Firman H05753

Thanks to its dual-fuel technology, the Firman H05753 delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 5700W and a peak wattage of 7125W. When propane-powered, it has 5700 rated watts and 7125 peak watts.

Enjoying a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), this generator can be started thanks to a conventional pull-start mechanism, but also to a simple and elegant electric starter (battery included).

The H05753, with a fuel capacity of 8 gallons, reaches a run time of around 12 hours at 50% load utilizing gasoline (fuel consumption around 0.67 GPH). Alternatively, it can reach a run time of around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH) with propane.

The H05753 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<25%).

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

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 the H05753 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

With its dimensions of L30.2 x W27.5 x H26.3 in, the conventional, open frame design of the Firman H05753 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.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 194.5 lbs. 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 H05753

The H05753's control panel

The H05753'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 the oil level is too low.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

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

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman H05753 also comes with some accessories: propane hose, funnel, oil and tool kit are included.

Emissions

The Firman H05753 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

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

Product Video

The Firman H05753 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H05753 compare to generators of similar power (between 5500 and 6500 W).

  • With a dry weight of 194.5 pounds, the Firman H05753 finds itself in the expected weight range for generators able to produce between 5500 and 6500 rated watts. If weight is your top priority, one of the champions in this power category is the Lifan LF7250, weighing just 140 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. For those who are looking for a less noisy device, we suggest the Honda EU7000iS. With just 52 dBA, it is one of the most quiet devices in this power range.
  • Since the H05753 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 concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Cat RP5500, boasting with 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 is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.67 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Lifan ESI 7000iER-EFI, which boasts with a gas consumption of only 0.38 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 5500-6500W generators, the Firman H05753 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.
