Zoom on the Firman H08053

In a nutshell, the Firman H08053 is a portable generator mostly geared towards:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • RV travellers who wish to upgrade their experience to another level

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 H08053 in use

The Firman H08053

With its dual-fuel technology, the powerful and versatile Firman H08053 provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 8,000W along with a peak wattage of 10,000W. While propane-powered, it provides 7,250 rated watts and 9,050 starting watts.

The generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a vacuum cleaner).

As for its running time, the H08053, 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 H08053 is unsuitable for the powering of sensitive electronic devices due to its high THD (<25%).

Outlets

The control panel provides the upcoming 5 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

If you own an RV with a 50-amp service, you can consider this Firman unit as RV-ready, as it features a 14-50R outlet. Its L5-30R receptacle can also be used for a simple RV connection with an L5-30P to TT-30R adaptor. In addition, as it features a twist-lock L14-30R receptacle, the H08053 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 design of the Firman H08053 is a typical, open frame, with the dimensions of L30.2 x W27.5 x H26.3 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 212 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

Panel of the Firman H08053

The H08053's control panel

The control panel of the H08053 includes a convenient meter showing you 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 includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman H08053 also comes with several accessories, including: funnel, tool kit, oil and propane hose.

Emissions

The Firman H08053 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, so it is adequate for use in forested areas.

The Firman H08053 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H08053 compare to dual fuel generators of similar power (between 7500 and 8500 W).

  • Since the generator weighs in at a dry weight of 212 lbs, the Firman H08053 belongs in the expected weight range for dual fuel devices which can produce between 7500 and 8500 rated watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Cummins Onan P9500df, with a dry weight of just 194 pounds.
  • Because this generator emits noise as low as 74 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you are concerned with noise, check out the Pulsar PGD95BiSCO, which is one of the least noisy generators in its power range, with a noise rating of just 62 dBA.
  • Since the H08053 boasts with a run time of around 12 hours at 50% load, it can be safely judged as one of the dual fuel devices with the highest run time among those of a comparable output.
  • 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 can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.67 GPH (gallon per hour) at 50% load, within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Pulsar PG10000B16, which boasts with a gas consumption of only 0.55 GPH, may be the right generator for you.
According to our stats, the following comparison is pretty popular: Firman H08053 vs Firman P08004.

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.

Can this unit be used to run furnaces that are power sensitive with circuit boards? (Asked May 21, 2020)

Probably not. The unit has a THD <23%. You'd have to check with your furnace manufacturer if that power is clean enough for these furnaces.

Can the neutral be unbounded from the frame? (Asked March 18, 2021)

No reason why this would not be impossible. You may refer to our article on neutral conversion.

    Overall a nice generator. Did the job for me for 10 straight hours when I lost power. I was happy to find a generator with a 50 amp outlet on it. That feature is hard to find anymore.

    + PROS:
    • Has 50 amp receptacle. Good power. Started right up with electric start. Ran for 10 hours straight right out of the box.
    - CONS:
    • Quite loud running, awkward putting gas in tank.

    My Firman dual fuel failed when the valve stem broke and lodged in the cylinder . It was a right off . I had it for less than a year . Customer service would not honor the warranty because they said I had not done ongoing servicing by adjusting valve settings and not doing clearance checks on the rocker arms and I could not prove I had done proper oil changes . Kiss goodbye to $1600

    + PROS:
    • Powerful
    - CONS:
    • Warranty is worthless .If their maintenance is so important and needs a schedule record put it right at the top of the generator . They asked for the reading on the hour meter . It does not have one , go figure
