Zoom on the Firman H08053
In summary, the Firman H08053 is a portable generator especially useful for food van owners and people participating in sporting competitions, open-air performances and outdoor festivals.
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
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 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).
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). Unfortunately, and despite our research efforts, we couldn't find any information regarding its runtime when using propane. Don't hesitate to let us know if you know it.
As the H08053 has a relatively high THD (<25%), it is not recommended to use it to power 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, 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.
The design of the Firman H08053 is a typical, open frame, with the dimensions of L29.8 x W27.5 x H26.1 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy 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. Never less, thanks to a wheel kit (⌀10") and a 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 showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.
In addition to this info, a light indicator allows you to instantly see if the oil level is too low.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
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.
With the basic documentation and a user manual, letting you start the generator quickly, the Firman H08053 also comes with several accessories, including: oil, tool kit, propane hose and funnel.
The Firman H08053 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
Moreover, it features a spark arrestor, making it usable 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. In terms of weight, one of the champions in their power range is the Lifan LF8750iEPL, standing at just 185 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 WEN GN9500, whose lowest noise levels reach just 64 dBA.
- Thanks to an impressive running time of around 12 hours at 50% load, the H08053 benefits from one of the highest run time of generators of a similar output.
- 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. 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 fuel consumption is your top priority, we suggest to check out the Westinghouse WPro8500, which has a fuel consumption of only 0.55 GPH and thus, is one of the most efficient devices in our database.
