Zoom on the Firman P08003

In summary, the Firman P08003 is a portable generator especially useful for:

  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals in need of safely powering high-intensity work or lighting equipment
  • RV travellers looking for even more independence

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 Firman P08003 in use

The Firman P08003

The Firman P08003 houses a 439 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 8,000W along with a peak wattage of 10,000W.

With a noise rating of 74 dBA (just slightly more noisy than a dishwasher), the generator features a conventional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included). Moreover, to offer you even more convenience, the P08003 can also be remotely started (key fob included).

The fuel capacity of 8 gallons allows the P08003 to operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.67 GPH).

As the P08003 has a high THD (<25%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel provides the upcoming 6 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120V 30A (TT-30R) receptacle
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready. In addition, due to the featured twist-lock L14-30R receptacle, the P08003 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The Firman P08003 has a conventional, open frame design, of the following dimensions: L27.1 x W27.5 x H26.8 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy 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 208 lbs. 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.

Features

The P08003's control panel

The P08003'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 shows you if its oil levels are insufficient.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman P08003 also comes with several accessories, including: tool kit, funnel, oil and key fob.

Emissions

The Firman P08003 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The Firman P08003 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman P08003 compare to generators of similar power (between 7500 and 8500 W).

  • With a dry weight of 208 pounds, the Firman P08003 finds itself in the expected weight range for generators able to produce between 7500 and 8500 rated watts. If weight is your top priority, one of the champions in this power category is the Westinghouse ecoGen10000, weighing just 147.7 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 Pulsar PGD95BiSCO, one of the least noisy generators similarly powerful as this one, rated for 62 dBA.
  • Thanks to an impressive running time of around 12 hours at 50% load, the P08003 benefits from a higher run time than many generators of a similar output. 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. 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.
According to our stats, the following comparison is pretty popular: Firman P08003 vs Firman P08004.
