Zoom on the Firman H03652
In summary, the Firman H03652 is a portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in outdoor fairs, festivals or events
- Homeowners in need of an emergency backup power for their essentials
- Professionals in need of safely powering high-intensity work or lighting equipment
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
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.
At a noise rating of 67 dBA (less noisy than an office), the generator is started via a simple traditional pull-start mechanism.
Regarding its running time, the H03652, with a 5 gallons fuel capacity can operate for around 14 hours at 50% load with a full tank of gasoline (fuel consumption around 0.36 GPH). When using propane, it can run for around 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH).
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 following 4 AC outlets:
This Firman generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').
Portability
The Firman H03652 has a conventional, open frame design, of the following dimensions: L25.7 x W21.8 x H21.6 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
As the generator's weight is 113 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Still, once it is on the ground, its wheel kit (⌀8") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
Features
The H03652's control panel
The H03652 and its control panel include a convenient meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.
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 far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
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, oil, tool kit and propane hose.
Emissions
The Firman H03652 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor, so it is adequate for use 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 dual fuel generators of similar power (between 3500 and 4500 W).
- At a weight of 113 pounds, the Firman H03652 places in the expected weight range of the dual fuel generators in the 3500-4500 rated wattage range. In terms of weight, one of the champions in their power range is the WEN DF402iX, standing at just 66.1 lbs.
- This generator has a somewhat average expected noise for its type and power range, rated at 67 dBA. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500DF, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
- Thanks to an impressive running time of around 14 hours at 50% load, the H03652 benefits from a higher run time than many dual fuel generators of a similar output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Westinghouse iGen4500DF, reaching 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. 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 are concerned with gasoline efficiency, having a fuel consumption of just 0.23 GPH, the Westinghouse iGen4500DF is a device you could look out for.
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.
