Zoom on the Firman P08003

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

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Professionals in need of safely powering high-intensity work or lighting equipment
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • RV travellers looking for even more independence

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.

With a noise rating of 74 dBA (just slightly more noisy than a shower), the generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included). The P08003 can also be remotely started, offering further convenience (key fob included).

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

The quite high THD (<25%) of the P08003 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel includes 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. The featured design is ideal for the outdoors and all tough environments.

Since the generator weighs 208 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is 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 control panel of the P08003 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

In addition to this info, a light indicator shows you if the oil level is too low.

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

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman P08003 also is packed along with the following accessories: key fob, funnel, tool kit 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, so it is adequate for use in forested areas.

Product Video

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 208 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 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. If noise emissions are one of your priorities, you may be interested in the Predator 9500, one of the least noisy generators similarly powerful as this one, rated for 67 dBA.
  • Thanks to an impressive running time of around 12 hours at 50% load, the P08003 benefits from one of the highest run times among generators of a similar output
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider 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 you are concerned with gasoline efficiency, having a fuel consumption of just 0.55 GPH, the Pulsar PG10000B16 is a device you should look out for.
According to our stats, the following comparison is pretty popular: Firman P08003 vs Firman P08004.

Price comparison

As you can see from this interactive chart, when compared to other 7500-8500W generators, the Firman P08003 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
