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 truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners in need of an emergency backup power for their essentials

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'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 vacuum cleaner), this generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included). To add further convenience, the P08004 can be remotely started (key fob included).

The fuel capacity of 8 gallons allows the P08004 to 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%).

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

This Firman generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. 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.

Portability

The design of the Firman P08004 is a typical, open frame, with the dimensions of L28.4 x W27.9 x H26.8 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy 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 210.3 pounds. 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.

Features

Panel of the Firman P08004

The P08004's control panel

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.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman P08004's package also includes these accessories: funnel, tool kit, oil and key fob.

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 weight matters to you, one of the champions in this power range is the Dewalt DXGNR8000 with only 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.
  • Thanks to an impressive running time of around 12 hours at 50% load, the P08004 benefits from a higher run time than many generators of a similar output. 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.
  • 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 acquire one of the most gasoline efficient products of this power range, the Westinghouse WPro8500, with a fuel consumption of 0.55 GPH could be in your good books.

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

Price comparison

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.

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.
