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 in need of an emergency backup power for their essentials

In the following paragraphs, we shall explore the power characteristics, available outlets, portability and any additional features of the device, along with its emission compliance parameters.

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 is rated for a noise of 72 dBA (just slightly more noisy than a shower). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included). For additional convenience, the P05703 may also be remotely started (key fob included).

With a full tank, the P05703 can operate for around 13 hours at 50% load (fuel consumption around 0.62 GPH), thanks 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%).

Here are a few examples of what this generator could allow you to simultaneously power:Note: The examples above are based on a maximum load of 75% and estimated wattages. The devices also may not be able to start at the same time. For a more accurate estimation, use our wattage calculator.

Outlets

The control panel features the upcoming 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

The design of the Firman P05703 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. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 178 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). 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.

Features

The P05703's control panel

The control panel of the P05703 includes a convenient meter showing you 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 generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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.

Apart from the typical documentation and a user manual, which lets you start it right away, the Firman P05703 also is packed along with the following accessories: oil, tool kit, funnel and key fob.

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, which makes it suitable 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).

  • Weight-wise, the Firman P05703 has only 178 lbs, which renders it one of the lighter generators which produce 5500 to 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.
  • This generator has a somewhat average expected noise for its power range, rated at 72 dBA. 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.
  • With a run time of 13 hours at 50% load, the P05703 has one of the higher run times, compared to its similarly powerful peers. 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 15 hours .
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. As this generator uses an estimated 0.62 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.38 GPH, the Lifan ESI 7000iER-EFI is a device you should look out for.

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.
