Zoom on the Firman H03652
In summary, the Firman H03652 is a portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- 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
Thanks to its dual-fuel technology, the Firman H03652 delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3,650W and a peak wattage of 4,550W. When propane-powered, it has 3,300 rated watts and 4,100 peak watts.
Enjoying a noise rating of 67 dBA (less noisy than background music), this generator gets running thanks to 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 high THD (<25%), it is not recommended to use it to power sensitive electronic devices.
Outlets
The control panel includes the following 4 AC outlets:
This Firman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').
Portability
The dimensions of the Firman H03652, which are L25.7 x W21.8 x H21.6 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 113 lbs. 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
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.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
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.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman H03652 also is packed along with the following accessories: funnel, propane hose, tool kit and oil.
Emissions
The Firman H03652 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.
Moreover, it features a spark arrestor and therefore, can 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 dual fuel generators of similar power (between 3500 and 4500 W).
- As its weight is 113 pounds, the Firman H03652 falls in the expected weight range of the dual fuel devices in the 3500-4500 rated wattage category. If weight is your top priority, one of the champions in this power category is the WEN DF402iX, weighing just 66.1 pounds.
- The generator can be considered average in its noise for its type and power category, as it is rated at 67 dBA. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Westinghouse iGen4500DF, whose lowest noise levels reach just 52 dBA.
- With a run time of around 14 hours at 50% load, the H03652 has one of the higher run times, compared to its similarly powerful peers. 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.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. As this generator uses an estimated 0.36 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4500DF. With a fuel consumption of as little as 0.23 GPH, it is one of the most efficient generators currently on the market.
Price comparison
As you can see from this interactive chart, 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.

User Reviews
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.
