Zoom on the Firman H03652

In a nutshell, the Firman H03652 is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to be able to deliver results, even during a power failure

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 H03652 in use

The Firman H03652

The dual-fuel technology of the Firman H03652 allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3650W and a starting wattage of 4550W. If propane-powered, it gives 3300 rated watts and 4100 starting watts.

At a noise rating of 67 dBA (less noisy than an office), the generator offers the possibility to start the device via a conventional pull-start mechanism.

As for its running time, the H03652, along with its 5 gallons fuel capacity, can run for around 14 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.36 GPH). If propane is used, it can operate for around 8 hours (on a 20 lbs tank - propane consumption around 0.59 GPH).

The powering of sensitive electronic devices with the H03652 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 features the upcoming 4 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120V 30A (TT-30R) receptacle

This Firman generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The Firman H03652 has the following dimensions: L25.7 x W21.8 x H21.6 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Since the generator weighs 112 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). However, its challenging mobility is solved by a wheel kit (⌀8") and a folding handle, which will ease its displacement, once it is on the floor.

Features

The H03652's control panel

The H03652's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours.

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.

While the standard documentation and a user manual, helpful for starting the device promptly, come with the Firman H03652, the following accessories are also included: propane hose, oil, tool kit and funnel.

Emissions

The Firman H03652 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The Firman H03652 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H03652 compare to generators of similar power (between 3500 and 4500 W).

  • With a dry weight of 112 pounds, the Firman H03652 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. If weight is your top priority, one of the champions in this power category is the Energizer eZV4500, weighing just 78 pounds.
  • Since the generator's noise is rated at 67 dBA, it has the roughly average expected noise for a device of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500 with only 52 dBA.
  • The H03652 provides a higher run time than similarly powerful devices, reaching 14 hours at 50% load. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000, boasting with 16 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. Standing at an estimated 0.36 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

Price comparison

As you can see from this dynamic chart, when compared to other 3500-4500W generators, the Firman H03652 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.
