Description
Zoom on the Firman H08053
In summary, the Firman H08053 is a portable generator especially useful for:
- Food van owners who know that just a short power outage could lose them hundreds of dollars
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- RV travellers wishing to enhance their freedom and nomad lifestyle
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Firman H08053
The dual-fuel technology of the Firman H08053 allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 8,000W and a starting wattage of 10,000W. If propane-powered, it gives 7,250 rated watts and 9,050 starting watts.
The generator is rated for a noise of 74 dBA (just slightly more noisy than a shower). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included).
Regarding its running time, the H08053, with a 8 gallons fuel capacity can operate for around 12 hours at 50% load with a full tank of gasoline (fuel consumption around 0.67 GPH). When using propane, it can run for around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH).
As the H08053 has a high THD (<25%), it is not recommended to use it to power sensitive electronic devices.
Outlets
The control panel features the upcoming 5 AC outlets:
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, due to the featured twist-lock L14-30R receptacle, the H08053 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
Portability
The Firman H08053 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 device has been designed for tough environments and demanding outdoor use.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 212 pounds. 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
The H08053's control panel
To help you monitor the H08053's status and activity, its control panel is equipped with 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 includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman H08053 also is packed along with the following accessories: oil, propane hose, funnel and tool kit.
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, which makes it suitable for use in forested areas.
Product Videos
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).
- At a weight of 212 pounds, the Firman H08053 places in the expected weight range of the dual fuel generators in the 7500-8500 rated wattage range. 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.
- The generator can be considered average in its noise for its type and power category, as it is rated at 74 dBA. For those who are looking for a less noisy device, we suggest the Genmax GM9000iED. With just 62 dBA, it is one of the most quiet devices in this power range.
- With a run time of around 12 hours at 50% load, the H08053 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. 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar PG10000B16. With a fuel consumption of as little as 0.55 GPH, it is one of the most efficient generators currently on the market.

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.

User Reviews
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.
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
Not impressed, only got to run it 3 hrs, flip the breaker nothing happens, installed new breaker still dont work !
