Zoom on the Firman P08003

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

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Professionals who want to ensure that a power failure will not prevent them from working
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • RV travellers who wish to upgrade their experience to another level

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 P08003 in use

The Firman P08003

The Firman P08003's core is the 439 cc Firman Max-Pro Series OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 8000W and a peak wattage of 10000W.

Enjoying a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included). For additional convenience, the P08003 may also be remotely started (key fob included).

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

The powering of sensitive electronic devices with the P08003 is not recommended due to its relatively high THD (<25%).

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

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Firman generator is RV Ready. In addition, as it features a twist-lock L14-30R receptacle, the P08003 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 Firman P08003 has the following dimensions: L28.4 x W27.9 x H26.8 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 210.3 lbs make it incredibly difficult to manually lift and transport. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.

Features

Panel of the Firman P08003

The P08003's control panel

The P08003 and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

In addition to this info, a light indicator shows you if its oil levels are insufficient.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman P08003's package also includes these accessories: tool kit, key fob, funnel and oil.

Emissions

The Firman P08003 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, making it usable 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).

  • As its weight is 210.3 pounds, the Firman P08003 falls in the expected weight range of the devices in the 7500-8500 rated wattage category. If weight matters to you, one of the champions in this power range is the Lifan LF8750iEPL with only 185 pounds.
  • The generator can be considered average in its noise for its power category, as it is rated at 74 dBA. If you are concerned with noise, check out the Powermate DF7500E, which is one of the least noisy generators in its power range, with a noise rating of just 68 dBA.
  • The P08003 provides one of the highest run time among similarly powerful devices, reaching around 12 hours at 50% load.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. 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 you wish to acquire one of the most gasoline efficient products of this power range, the Pulsar PG10000B16, with a fuel consumption of 0.55 GPH could be in your good books.
