Zoom on the Firman P08003

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

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Professionals in need of safely powering high-intensity work or lighting equipment
  • Homeowners in need of an emergency backup power for their essentials
  • RV travellers wishing to enhance their freedom and nomad lifestyle

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 design includes a gasoline-fueled 439 cc Firman Max-Pro Series OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 8000W and also a peak wattage of 10000W.

At a noise rating of 74 dBA (just slightly more noisy than a dishwasher), this generator can be started via a conventional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included). To add further convenience, the P08003 can be remotely started (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).

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

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

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready. In addition, as the P08003 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home 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. The design is ideal for rough environments and demanding outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 208 pounds. 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 showing you 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.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman P08003, the following accessories are also included: tool kit, oil, funnel and key fob.

Emissions

The Firman P08003 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used 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).

  • 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 is your top priority, one of the champions in this power category is the Dewalt DXGNR8000, weighing just 183 pounds.
  • The generator can be considered average in its noise for its power category, as it is rated at 74 dBA. 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.
  • As the P08003 features an autonomy of around 12 hours at 50% load, it has a higher run time than an average generator of its power range. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 100416, reaching around 12.5 hours.
  • 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. This generator, with an estimated fuel consumption of just 0.67 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the Pulsar PG10000B16, which boasts with a gas consumption of only 0.55 GPH, may be the right generator for you.
According to our stats, the following comparison is pretty popular: Firman P08003 vs Firman P08004.

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.
