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.
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 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 8000W and a starting wattage of 10000W. If propane-powered, it gives 7250 rated watts and 9050 starting watts.
Enjoying a noise rating of 74 dBA (just slightly more noisy than a shower), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included).
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 powering of sensitive electronic devices with the H08053 is not recommended due to its relatively high THD (<25%).
The control panel features the following 5 AC outlets:
While this Firman generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, 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.
With its dimensions of L30.2 x W27.5 x H26.3 in, the conventional, open frame design of the Firman H08053 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.
As the generator's weight is 212 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by its wheel kit (⌀10") and its folding handle, with which you can conveniently shift it, once it's on the ground.
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 the oil level is too low, you will be informed by the featured light indicator.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
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: tool kit, funnel, oil 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).
- Since the generator weighs in at a dry weight of 212 lbs, the Firman H08053 belongs in the expected weight range for 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 Lifan LF8750iEPL, with a dry weight of just 185 pounds.
- This generator has a somewhat average expected noise for its power range, rated at 74 dBA. If noise emissions are one of your priorities, you may be interested in the Powermate DF7500E, one of the least noisy generators similarly powerful as this one, rated for 68 dBA.
- The H08053 provides one of the highest run time among similarly powerful devices, reaching around 12 hours at 50% load.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency 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 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.
