Description

The P05703 is a larger open frame portable generator, perfect for portable backup power during an emergency, or for construction. This generator features 7100 starting watts and 5700 running watts, with a recoil, electric and remote start for ease of use. (source: Firman (opens in a new tab))

Zoom on the Firman P05703

In a nutshell, the Firman P05703 is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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 P05703's engine, 389 cc Firman Max-Pro Series OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 5700W and reaches a peak wattage of 7125W.

The generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 72 dBA (just slightly more noisy than a dishwasher). The P05703 can also be remotely started, offering further convenience (key fob included).

With a fuel capacity of 8 gallons, the P05703 may run for around 13 hours at 50% load with a full tank (fuel consumption around 0.62 GPH).

The powering of sensitive electronic devices with the P05703 is not recommended due to its relatively high THD (<25%).

Outlets

The control panel provides the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) 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, as the P05703 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

With its dimensions of L28.4 x W27.9 x H26.8 in, the conventional, open frame design of the Firman P05703 offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough 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 178 pounds. 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

Panel of the Firman P05703

The P05703's control panel

The P05703 and its control panel include a convenient meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

In addition to this info, a light indicator shows you if the oil level is too low.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman P05703, the following accessories are also included: oil, tool kit, key fob and funnel.

Emissions

The Firman P05703 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, so it is adequate for use in forested areas.

The Firman P05703 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman P05703 compare to generators of similar power (between 5500 and 6500 W).

  • As far as its dry weight is concerned, the Firman P05703 weighs just 178 pounds and thus, it is one of the lighter 5500 to 6500 rated wattage generators. If weight is your top priority, one of the champions in this power category is the Lifan LF7250, weighing just 140 pounds.
  • As this generator can emit noise as low as 72 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are one of your priorities, you may be interested in the Honda EU7000iS, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • Thanks to an impressive running time of around 13 hours at 50% load, the P05703 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 Cat RP5500, which is able to run for around 15 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. This generator has an estimated fuel consumption of roughly 0.62 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If fuel consumption is your top priority, we suggest to check out the Lifan ESI 7000iER-EFI, which has a fuel consumption of only 0.38 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 5500-6500W generators, the Firman P05703 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
