Description
Zoom on the Firman P08004
In summary, the Firman P08004 is a portable generator especially useful for:
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Homeowners in need of an emergency backup power for their essentials
- RV travellers who wish to upgrade their experience to another level
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, and the extra features it benefits from.
Power & Run Time
With a 439 cc Firman Max-Pro Series OHV 4-stroke engine, the Firman P08004 operates on gasoline, providing 120/240V, with a running wattage of 8,000W and a starting wattage of 10,000W.
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 an intuitive and practical electric starter (battery included). Additionally, the P08004 features remote starting, offering users increased convenience (key fob included).
With its 8 gallons fuel tank, the P08004 can operate for around 12 hours at 50% load when fully fueled (with fuel usage averaging around 0.67 GPH).
Since the P08004 has a high THD (<25%), it is advisable to not use it for the powering of sensitive electronic devices.
Outlets
The control panel features 5 AC outlets as follows:
If your RV requires a 50-amp service, consider this Firman unit RV-ready, as it includes a 14-50R outlet. In addition, since it features a twist-lock L14-30R receptacle, the P08004 is tailored to be transfer switch ready, making it easy to connect it to your breaker box for home power support during outages.
Portability
Measuring L28.4 x W27.9 x H26.8 in, the Firman P08004 showcases a classic open frame layout, guaranteeing stability and simple maintenance access to components, while facilitating air circulation. This type of design is ideal for tough environments and heavy outdoor use.
Despite its weight of 210.3 lbs, the generator is considered 'portable,' signifying its capability to be moved, albeit its heaviness may hinder easy transport. However, its challenging mobility is solved by its wheel kit (⌀10") and its folding handle, which will ease its displacement, once it is on the floor.
Features
The P08004's control panel
The control panel of the P08004 is equipped with a convenient meter, offering voltage, frequency, and lifetime hours readings, aiding in monitoring its status and activity.
In addition to this info, a light indicator serves to show you when its oil levels are insufficient.
The inclusion of a built-in fuel gauge in the generator streamlines gas level checks for quick and convenient assessments.
As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during use.
Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the Firman P08004 is bundled with additional accessories: tool kit, funnel, oil and key fob.

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. Weight-conscious users may find the Westinghouse ecoGen10000 appealing, as it is one of the top contenders in this power range, weighing just 147.7 pounds.
- The generator's noise output, rated at 74 dBA, falls within the average range expected for devices in its power range. If you wish to prioritize minimal noise, the DuroMax XP9500iH stands out as one of the quietest options among generators of similar power, with a rating of 61 dBA.
- In terms of run time, the P08004 surpasses similarly powerful devices, boasting one of the higher run times at around 12 hours. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 100416, as it provides around 12.5 hours.
- While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. This generator is one of the more fuel-efficient options in its power range, consuming approximately 0.67 GPH (gallon per hour) at 50% load. If gasoline efficiency is at the top of your list, you may want to have a look at the Cummins Onan P9500df, which has great fuel efficiency, with a gas consumption of only 0.6 gallons per hour.
The bottom line
- Several accessories included
- 4 different AC outlet types
- Remote start
- High run time
- Fuel efficient
- Decent weight (210.3 lbs)
- Acceptable noise (74 dBA)
The Firman P08004 doesn't have any notably low specs.
