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 who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners in need of an emergency backup power for their essentials

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 is powered by a 389 cc Firman Max-Pro Series OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 5700W as well as a peak wattage of 7125W.

With a noise rating of 74 dBA (just slightly more noisy than a shower), the generator features a conventional pull-start mechanism, but also a simple and elegant electric starter (battery included). For additional convenience, the P05703 may also be remotely started (key fob included).

The fuel capacity of 8 gallons allows the P05703 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 P05703 is not recommended due to its relatively high THD (<25%).

Outlets

The control panel features the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

While this Firman generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, because the P05703 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.

Portability

With its dimensions of L28.4 x W27.5 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 design is ideal for rough environments and demanding outdoor use.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 203 lbs. Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Firman P05703

The P05703's control panel

The control panel of the P05703 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

In addition to this info, the device’s light indicator will display if the oil level is too low.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman P05703's package also includes these accessories: key fob, oil, tool kit 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 and thus, may be used 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).

  • Since the generator weighs in at a dry weight of 203 lbs, the Firman P05703 belongs in the expected weight range for devices which can produce between 5500 and 6500 rated watts. Regarding dry weight, one of the champions in the same power range is the Lifan LF7250, with a dry weight of only 140 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 noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU7000iS with only 52 dBA.
  • Since the P05703 boasts with a run time of around 12 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable 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.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.67 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Lifan ESI 7000iER-EFI. With a fuel consumption of as little as 0.38 GPH, it is one of the most efficient generators currently on the market.

Price comparison

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

It can therefore be a really good buy if you're looking to acquire a budget generator.
