Zoom on the Firman P08004
In a nutshell, the Firman P08004 is a portable generator mostly geared towards food truck owners who do not wish to see their business interrupted under any circumstances.
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Firman P08004's engine, 439 cc Firman Max-Pro Series OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 8000W and reaches 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 simple and elegant electric starter (battery included). For additional convenience, the P08004 may also be remotely started (key fob included).
Thanks to a fuel capacity of 8 gallons, the P08004 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 P08004 is not recommended due to its relatively high THD (<25%).
The control panel includes the following 5 AC outlets:
Even though this Firman generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, because the P08004 is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
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 design is ideal for rough environments and demanding outdoor use.
As the generator's weight is 210.3 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.
To help you monitor the P08004's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.
In addition to this info, when the oil level is too low, you will be informed by the featured light indicator.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
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: tool kit, key fob, funnel and oil are included.
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 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).
- Having a dry weight of 210.3 lbs, the Firman P08004 belongs in the expected weight range for generators which produce 7500 to 8500 rated watts. In terms of weight, one of the champions in their power range is the Lifan LF8750iEPL, standing at just 185 lbs.
- 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 Powermate DF7500E, whose lowest noise levels reach just 68 dBA.
- The P08004 provides one of the highest run time among similarly powerful devices, reaching around 12 hours at 50% load.
- 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. 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.
As you can see from this interactive 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

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.
