Zoom on the Firman H05753

In a nutshell, the Firman H05753 is a portable generator mostly geared towards:

  • 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

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

With its dual-fuel technology, the powerful and versatile Firman H05753 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.

At a noise rating of 74 dBA (just slightly more noisy than a shower), this generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included).

As for its running time, the H05753, 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 powering of sensitive electronic devices with the H05753 is not recommended due to its relatively high THD (<25%).

The generator will allow you to simultaneously power various devices, for example:Note: All of these devices might not start simultaneously. Provided examples are based on a maximum load of 75 % and estimated wattages. With the help of our wattage calculator you can find out if this product suits your requirements.

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

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, as the H05753 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 Firman H05753 has a conventional, open frame design, of the following dimensions: L29.8 x W27.5 x H26.1 in, which offers support and allows it to be raised above ground level. The device has been designed for tough environments and demanding 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 196 pounds. Never less, thanks to a wheel kit (⌀10") and a folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

The H05753's control panel

To help you monitor the H05753's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

In addition to this info, a light indicator serves to show you when 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.

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.

Apart from the typical documentation and a user manual, which lets you start it right away, the Firman H05753 also is packed along with the following accessories: tool kit, propane hose, funnel and oil.

Emissions

The Firman H05753 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 H05753 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H05753 compare to generators of similar power (between 5500 and 6500 W).

  • As its weight is 196 pounds, the Firman H05753 falls in the expected weight range of the devices in the 5500-6500 rated wattage category. If you are concerned by weight, one of the champions in the above mentioned power range is the Lifan LF7250, with a dry weight of 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 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.
  • Since the H05753 boasts with a run time of 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 concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Cat RP5500, boasting with 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 reaches an estimated fuel consumption of 0.62 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the Lifan ESI 7000iER-EFI, which boasts with a gas consumption of only 0.38 GPH, may be the right generator for you.

Price comparison

As you can see from this dynamic chart, when compared to other 5500-6500W generators, the Firman H05753 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.
