Zoom on the Firman H08053
In a nutshell, the Firman H08053 is a portable generator mostly geared towards food van owners who know that just a short power outage could lose them hundreds of dollars.
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
Thanks to its dual-fuel technology, the Firman H08053 delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 8000W and a peak wattage of 10000W. When propane-powered, it has 7250 rated watts and 9050 peak 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 dishwasher).
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).
The quite high THD (<25%) of the H08053 makes it unsuitable for powering sensitive electronic devices.
The control panel features the upcoming 5 AC outlets:
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, since the H08053 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.
The Firman H08053 has the following dimensions: L29.8 x W27.5 x H26.1 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 212 lbs make it incredibly difficult to manually lift and transport. 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.
The H08053'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 shows you if the oil level is too low.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its 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.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman H08053's package also includes these accessories: oil, tool kit, funnel and propane hose.
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.
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 generators of similar power (between 7500 and 8500 W).
- Having a dry weight of 212 lbs, the Firman H08053 belongs in the expected weight range for generators which produce 7500 to 8500 rated watts. If weight matters to you, one of the champions in this power range is the Lifan LF8750iEPL with only 185 pounds.
- This generator has a somewhat average expected noise for its power range, rated at 74 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Powermate DF7500E with only 68 dBA.
- Thanks to an impressive running time of around 12 hours at 50% load, the H08053 benefits from one of the highest run times among generators of a similar output
- While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider 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 fuel consumption is your top priority, we suggest to check out the Pulsar PG10000B16, which has a fuel consumption of only 0.55 GPH and thus, is one of the most efficient devices in our database.

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.
