Description
Zoom on the Firman H03652
In a nutshell, the Firman H03652 is a portable generator mostly geared towards:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and 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 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
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.
With a noise rating of 67 dBA (less noisy than a normal conversation), the generator features a simple traditional pull-start mechanism.
The H03652, with a fuel capacity of 5 gallons, reaches a run time of around 14 hours at 50% load utilizing gasoline (fuel consumption around 0.36 GPH). Alternatively, it can reach a run time of around 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH) with propane.
As the H03652 has a relatively high THD (<25%), it is not recommended to use it to power sensitive electronic devices.
Outlets
The control panel features the upcoming 4 AC outlets:
This Firman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').
Portability
With its dimensions of L25.7 x W21.8 x H21.6 in, the conventional, open frame design of the Firman H03652 offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.
Since the generator weighs 113 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). Nevertheless, thanks to its wheel kit (⌀8") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
Features
The H03652's control panel
To help you monitor the H03652's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.
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.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman H03652, the following accessories are also included: tool kit, propane hose, funnel and oil.
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.
Product Videos
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).
- Since the generator weighs in at a dry weight of 113 lbs, the Firman H03652 belongs in the expected weight range for devices which can produce between 3500 and 4500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 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 you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
- As the H03652 features an autonomy of around 14 hours at 50% load, it has a higher run time than an average generator of its power range. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Predator 4375, with around 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. This generator has an estimated fuel consumption of roughly 0.36 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.
Price comparison
As you can see from this interactive chart, when compared to other 3500-4500W 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.
