Zoom on the Firman H05752

In a nutshell, the Firman H05752 is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to ensure that a power failure will not prevent them from working

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

With its dual-fuel technology, the powerful and versatile Firman H05752 provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 5700W along with a peak wattage of 7125W. While propane-powered, it provides 5700 rated watts and 7125 starting watts.

The generator features a simple traditional pull-start mechanism. It is rated for a noise of 74 dBA (just slightly more noisy than a vacuum cleaner).

As for its running time, the H05752, along with its 8 gallons fuel capacity, can run for around 13 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.62 GPH). Unfortunately, and despite our research efforts, we couldn't find any information regarding its runtime when using propane. Don't hesitate to let us know if you know it.

The quite high THD (<25%) of the H05752 makes it unsuitable for powering sensitive of electronic devices.

Here are a few examples of what this generator could allow you to simultaneously power:Note: Not all of these items may be able to start at the same time. These examples are based on a maximum load of 75 % and on wattage estimates. Use our wattage calculator to find out if this product will be suitable for your needs.

Outlets

The control panel provides the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
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, due to the featured twist-lock L14-30R receptacle, the H05752 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

With its dimensions of L29.8 x W27.5 x H26.1 in, the conventional, open frame design of the Firman H05752 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.

As the generator's weight is 176 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (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.

The H05752's control panel

To help you monitor the H05752's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.

In addition to this info, the device’s light indicator will display if its oil levels are insufficient.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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.

With the basic documentation and a user manual, letting you start the generator quickly, the Firman H05752 also comes with several accessories, including: tool kit, oil, funnel and propane hose.

Emissions

The Firman H05752 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

The Firman H05752 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H05752 compare to generators of similar power (between 5500 and 6500 W).

  • Weight-wise, the Firman H05752 has only 176 lbs, which renders it one of the lighter generators which produce 5500 to 6500 rated watts. If weight matters to you, one of the champions in this power range is the Lifan LF7250 with only 140 pounds.
  • 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 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 H05752 has one of the higher run times, compared to its similarly powerful peers. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Cat RP5500, reaching 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 average fuel consumption among comparably powerful devices, as it reaches 0.62 GPH (gallon per hour) at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Lifan ESI 7000iER-EFI, with a fuel consumption of 0.38 GPH could be in your good books.

Price comparison

As you can see from this dynamic chart, when compared to other 5500-6500W generators, the Firman H05752 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.
