Zoom on the Firman P08004
In summary, the Firman P08004 is a portable generator especially useful for food van owners and people participating in sporting competitions, open-air performances and outdoor festivals.
Power & Run Time
The Firman P08004'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 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). For additional convenience, the P08004 may also be remotely started (key fob included).
With a fuel capacity of 8 gallons, the P08004 may run 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 P08004 is not recommended due to its relatively high THD (<25%).
The control panel features the upcoming 5 AC outlets:
This Firman generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, due to the featured twist-lock L14-30R receptacle, the P08004 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
The Firman P08004 has a conventional, open frame design, of the following dimensions: L28.4 x W27.9 x H26.8 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 210.3 pounds. However, its challenging mobility is solved by a wheel kit (⌀10") and a folding handle, which will ease its displacement, once it is on the floor.
The P08004'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 serves to show you when 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.
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.
With the basic documentation and a user manual, letting you start the generator quickly, the Firman P08004 also comes with several accessories, including: key fob, funnel, tool kit and oil.
The Firman P08004 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
Moreover, it features a spark arrestor and therefore, can be used 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).
- With a dry weight of 210.3 pounds, the Firman P08004 finds itself in the expected weight range for generators able to produce between 7500 and 8500 rated watts. If weight matters to you, one of the champions in this power range is the Lifan LF8750iEPL with only 185 pounds.
- As this generator can emit noise as low as 74 dBA, it finds itself in the average expected noise for this kind of 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 Powermate DF7500E, whose lowest noise levels reach just 68 dBA.
- As the P08004 features an autonomy of 12 hours at 50% load, it has a higher run time than an average generator of its power range.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. With an estimated gasoline consumption of 0.67 GPH (gallon per hour) at 50% load, this generator is among the more fuel efficient of the products in the above-mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the Westinghouse WPro8500, which boasts with a gas consumption of only 0.55 GPH, may be the right generator for you.
As you can see from this dynamic chart, when compared to other 7500-8500W generators, the Firman P08004 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
The bottom line
- In the expected price range
- Several accessories included
- Remote start
- High run time
- Fuel efficient
- Decent weight (210.3 lbs)
- Acceptable noise (74 dBA)
- Not CARB-compliant

Questions & Answers
QCan this model be converted to propane? Is there a conversion kit? (Asked September 04, 2019)
ATo 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.
