Description

The FIRMAN P05706 generator features 7100 starting Watts and 5700 running watts. Power is supplied by our Max Pro Series 389cc FIRMAN engine which runs cool and efficient thanks to its Phoenix Fat Head Block. Our Whisper Series muffler keeps the P05706 running at 72 decibels, and our spark arrester has been approved by the USDA Forest Service. The industry-leading 8-gallon fuel capacity provides a whopping 13 hours of run time. Our rubberized Thresher handle makes recoil starting a snap – even with bulky gloves.

Zoom on the Firman P05706

In summary, the Firman P05706 is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • 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 sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

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 P05706 in use

The Firman P05706

The Firman P05706 houses a 389 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 5700W along with a peak wattage of 7125W.

The generator is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher). Its starting mechanism is based on a conventional pull-start mechanism.

The fuel capacity of 8 gallons allows the P05706 to operate for around 13 hours at 50% load with a full tank (fuel consumption around 0.62 GPH).

As the P05706 has a relatively high THD (<25%), it is not recommended to use it to power sensitive electronic devices.

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

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, as the P05706 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

The dimensions of the Firman P05706, which are L28.4 x W27.5 x H26.8 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. This type of design is ideal for tough environments and heavy 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 178 lbs. 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 P05706

The P05706's control panel

The P05706's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with 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.

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

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman P05706 also is packed along with the following accessories: tool kit, oil and funnel.

Emissions

The Firman P05706 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, making it usable in forested areas.

The Firman P05706 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman P05706 compare to generators of similar power (between 5500 and 6500 W).

  • Weight-wise, the Firman P05706 has only 178 lbs, which renders it one of the lighter generators which produce 5500 to 6500 rated watts. If weight is your top priority, one of the champions in this power category is the Lifan LF7250, weighing just 140 pounds.
  • Because this generator emits noise as low as 74 dBA, it can be considered to have a pretty average expected noise rating for a device of its 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.
  • With a run time of around 13 hours at 50% load, the P05706 has one of the higher run times, compared to its similarly powerful peers. 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 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 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.

The bottom line

STRENGTHS:
  • Several accessories included
  • Lightweight for its kind (178 lbs)
  • High run time
AVERAGE SPECS:
  • Acceptable noise (74 dBA)
  • Decent fuel efficiency
WEAKNESSES:
  • No electric start
  • Not CARB-compliant
