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 sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
The Firman H08053
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.
Enjoying a noise rating of 74 dBA (just slightly more noisy than a dishwasher), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included).
With a fuel capacity of 8 gallons, the H08053 can operate for around 12 hours at 50% load using gasoline (fuel consumption around 0.67 GPH), or for around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH) using propane.
The quite high THD (<25%) of the H08053 makes it unsuitable for powering sensitive electronic devices.
Outlets
The control panel includes the following 5 AC outlets:
This Firman generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, 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 device has been designed for tough environments and demanding 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 212 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
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, a light indicator allows you to instantly see if its oil levels are insufficient.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
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.
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, 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 generators of similar power (between 7500 and 8500 W).
- With a dry weight of 212 pounds, the Firman H08053 finds itself in the expected weight range for generators able to produce between 7500 and 8500 rated watts. In terms of weight, one of the champions in their power range is the Dewalt DXGNR8000, standing at just 183 lbs.
- As this generator can emit noise as low as 74 dBA, it finds itself in the average expected noise for this kind of power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Predator 9500, whose lowest noise levels reach just 67 dBA.
- With a run time of around 12 hours at 50% load, the H08053 has one of the higher run times, compared to its similarly powerful peers. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 100416, boasting with around 12.5 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. With an estimated gasoline consumption of 0.67 GPH (gallon per hour) at 50% load, this generator is among the more fuel efficient of the products in the above-mentioned 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.
The bottom line
- Several accessories included
- Electric start
- Dual Fuel
- High run time
- Fuel efficient
- Decent weight (212 lbs)
- Acceptable noise (74 dBA)
- No remote start
- Not CARB-compliant

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.
