Zoom on the Firman H03652

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

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to be able to deliver results, even during a power failure

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.

Power & Run Time

The Firman H03652 in use

The Firman H03652

With its dual-fuel technology, the powerful and versatile Firman H03652 provides an output of 120V. While gasoline-powered, it gives a running wattage of 3,650W along with a peak wattage of 4,550W. While propane-powered, it provides 3,300 rated watts and 4,100 starting watts.

Enjoying a noise rating of 67 dBA (less noisy than an office), this generator gets running thanks to a conventional pull-start mechanism.

The running time of the H03652, with its 5 gallons fuel capacity, can reach around 14 hours at 50% load on a full tank of gasoline (fuel consumption around 0.36 GPH). With propane, it can reach around 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH).

As the H03652 exhibits a THD of less than 25%, which is high, it is best avoided for powering sensitive electronic devices.

Outlets

The control panel is equipped with the following 4 AC outlets:

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

Equipped with a TT-30R receptacle (TT representing 'Travel Trailer'), this Firman generator is RV Ready, ensuring compatibility with recreational vehicles.

Portability

At L25.7 x W21.8 x H21.6 in, the traditional open frame structure of the Firman H03652 ensures stability while facilitating convenient maintenance access to components and promoting air cooling. The generator is designed for ideal use outdoors and in rough environments.

With a weight of 113 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀8") and its folding handle, once it is placed on the ground.

Features

Panel of the Firman H03652

The H03652's control panel

Integrated into the control center of the H03652 are a convenient meter, showing voltage, frequency, and lifetime hours metrics, facilitating the monitoring of its status and activity.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Firman H03652 ships with supplementary accessories: oil, propane hose, tool kit and funnel.

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 dual fuel generators of similar power (between 3500 and 4500 W).

  • Since the generator weighs in at a dry weight of 113 lbs, the Firman H03652 belongs in the expected weight range for dual fuel devices which can produce between 3500 and 4500 rated watts. Weight-conscious users may find the WEN DF402iX appealing, as it is one of the top contenders in this power range, weighing just 66.1 pounds.
  • At 67 dBA, this generator's noise rating is in line with the expected average for devices within its type and power category. If noise level is one your key decisive factors, you may find the Westinghouse iGen4500DF appealing. It's rated at 52 dBA, making it one of the quietest generators in its power range.
  • With around 14 hours of runtime at 50% load, the H03652 provides a higher run time when compared to similarly powerful dual fuel products. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse iGen4500DF, which is able to run for around 15 hours.
  • While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. The generator utilizes approximately 0.36 GPH of gasoline at a 50% load, placing it within the typical range of fuel consumption seen in products of comparable wattage. If minimizing fuel usage is one of your key priorities, the Westinghouse iGen4500DF is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.23 gallons per hour.
According to our stats, the following comparison is pretty popular: Firman H03652 vs Firman H03651.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W dual fuel generators, the Firman H03652 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

Can the Firman H03652 dual fuel model be fitted to use natural gas? (Asked January 20, 2020)

Firman doesn't seem to have an official natural gas conversion kit. You could have a look at this article: https://www.propane101.com/lpgasapplianceconversions.htm. Needless to say, without an official conversion kit, such conversion would immediately void any warranty you may have.

    I purchased the Firman on 8/23/20 and recd it 9/3/20. Well packaged with only having to attach sturdy wheel and front rubber ft. Easily pulled to back yard by my small pool shed. Easy to ck oil and add oil. Gas ready right on top.
    I wanted to run on propane tanks as they are easy to store & last two yrs or more without spoiling. It Was HARD to start comparing to my son’s Champion.
    His pills by 2nd pull. This takes two pulls on choke, then at least 4-5 pulls to get it going on “run“ . After running though, it was nice and smooth for the 5 hours with the light load that the instructions said to use during 5 hrs break in period. I shut her down and put it away. Negative- the plastic choke lever is cheaply done. It seems off center from the “choke” & “Run” markings. I will call “services” about this. I like the meter. I can see Volts-Amps- total hrs run – Gas Fuel Guage is a Nice item too. I live in Texas and our Power goes out in heavy Tropical Storms Hurricanes. My Briggs & Stratton lasted from KY2 1999-2000 until last summer but I kept holding off until last minute before ordering this Firman. (Lucked out and the hurricane struck Lake Charles,La. instead.)
    I made it thur Ike and Harvey with a couple of trees down and 11 days without power) Hope this review helps.
    Steve

    + PROS:
    • Good price with Military Discount for a portable Generator with features that can run two refrig. At one time.
    • And good running time if 14 hrs gas.
    • Hope the propane will be 10 hrs on 20 lb tank.
    - CONS:
    • Cheap plastic choke lever and hard starting pull. Also, it won’t run on Propane tank if small acid-lead battery is low or dead! But, manual does state it would run on Gas with no battery.
