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)

Zoom on the Firman P05703

In summary, the Firman P05703 is a portable generator especially useful for:

  • RV travellers looking for even more independence
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

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.

With a noise rating of 72 dBA (just slightly more noisy than a shower), the generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included). To add further convenience, the P05703 can be remotely started (key fob included).

The P05703 can operate for around 13 hours at 50% load with a full tank (fuel consumption around 0.62 GPH), due to its fuel capacity of 8 gallons.

The P05703 is unsuitable for the powering of sensitive electronic devices 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

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, since the P05703 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of 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. 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 178 pounds. Still, once it is on the ground, a wheel kit (⌀10") and a folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

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, a light indicator serves to show you when the oil level is too low.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

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.

Besides the classic documentation and a user manual to get you promptly started, the Firman P05703 also comes with some accessories: key fob, tool kit, funnel and oil are included.

Emissions

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

Moreover, 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).

  • Regarding its weight, the Firman P05703 only weighs in at 178 pounds, which means it's one of the lighter generators in the 5500-6500 rated wattage range. In terms of weight, one of the champions in their power range is the Lifan LF7250, standing at just 140 lbs.
  • Since the generator's noise is rated at 72 dBA, it has the roughly average expected noise for a device of similar power. If you are concerned with noise, check out the Honda EU7000iS, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Since the P05703 boasts with a run time of around 13 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Cat RP5500, with 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 has an average fuel consumption among comparably powerful devices, as it reaches 0.62 GPH (gallon per hour) at a 50% load. 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 dynamic 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.
