This unit might be hard to find. For your convenience, we gathered the following alternatives with similar specs:

Description

The P08004 is a larger open frame portable generator, perfect for portable backup power during an emergency, or for construction. This generator features 10000 starting watts and 8000 running watts, with a recoil, electric and remote start for ease of use. (source: Firman (opens in a new tab))

Zoom on the Firman P08004

In a nutshell, the Firman P08004 is a portable generator mostly geared towards:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners in need of an emergency backup power for their essentials
  • RV travellers wishing to enhance their freedom and nomad lifestyle

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Firman P08004 is powered by a 439 cc Firman Max-Pro Series OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 8000W as well as 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 simple traditional pull-start mechanism, or a simple and elegant electric starter (battery included). To add further convenience, the P08004 can be remotely started (key fob included).

With a full tank, the P08004 can operate for around 12 hours at 50% load (fuel consumption around 0.67 GPH), thanks to its fuel capacity of 8 gallons.

The powering of sensitive electronic devices with the P08004 is not recommended due to its relatively high THD (<25%).

Outlets

The control panel includes the following 5 AC outlets:

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

If you own an RV with a 50-amp service, you can consider this Firman unit as RV-ready, as it features a 14-50R outlet. Its L5-30R receptacle can also be used for a simple RV connection with an L5-30P to TT-30R adaptor. In addition, as it features a twist-lock L14-30R receptacle, the P08004 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 P08004 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.

Since the generator weighs 210.3 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). 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 P08004's control panel

The control panel of the P08004 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 its oil levels are insufficient.

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

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

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman P08004 also comes with some accessories: key fob, funnel, tool kit and oil are included.

Emissions

The Firman P08004 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, which makes it suitable for use in forested areas.

The Firman P08004 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman P08004 compare to generators of similar power (between 7500 and 8500 W).

  • Since the generator weighs in at a dry weight of 210.3 lbs, the Firman P08004 belongs in the expected weight range for devices which can produce between 7500 and 8500 rated watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Dewalt DXGNR8000, with a dry weight of just 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 you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Champion 100719, whose lowest noise levels reach just 61 dBA.
  • As the P08004 features an autonomy of around 12 hours at 50% load, it has a higher run time than an average generator of its power range. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 100416, which is able to run for around 12.5 hours.
  • 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. 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 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.

Here's a list of the most popular specific comparisons:

Can this model be converted to propane? Is there a conversion kit? (Asked September 04, 2019)

To our knowledge, there is no official Firman propane conversion kit. You may want to have a look at the H08051, which is already dual fuel and has the same power output. It doesn't have the remote start, though.

Can I turn it off with just the remote for overnight? (Asked September 24, 2022)

The remote can be used for both remote start and remote stop.
