Zoom on the Firman P08003

In a nutshell, the Firman P08003 is a portable generator mostly geared towards:

  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to be able to deliver results, even during a power failure
  • 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 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.

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). The P08003 can also be remotely started, offering further convenience (key fob included).

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

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

Outlets

The control panel features the following 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

This Firman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer'). In addition, since the P08003 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The dimensions of the Firman P08003, which are L27.1 x W27.5 x H26.8 in, and its typical, open frame design provides stability and enables 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 208 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the Firman P08003

The P08003's control panel

The P08003's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you 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 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.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman P08003 also comes with some accessories: tool kit, funnel, oil and key fob are included.

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, 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).

  • Since the generator weighs in at a dry weight of 208 lbs, the Firman P08003 belongs in the expected weight range for devices which can produce between 7500 and 8500 rated watts. If weight matters to you, one of the champions in this power range is the Dewalt DXGNR8000 with only 183 pounds.
  • Since the generator's noise is rated at 74 dBA, it has the roughly average expected noise for a device of similar power. For those who are looking for a less noisy device, we suggest the Genmax GM9000iED. With just 62 dBA, it is one of the most quiet devices in this power range.
  • 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 you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Champion 100416, with around 12.5 hours.
  • 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. At an estimated fuel consumption of 0.67 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.55 GPH, the Pulsar PG10000B16 is a device you could look out for.
According to our stats, the following comparison is pretty popular: Firman P08003 vs Firman P08004.
