Description
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
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Homeowners in need of an emergency backup power for their essentials
- Professionals who want to ensure that a power failure will not prevent them from working
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
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 3650W and a peak wattage of 4550W. When propane-powered, it has 3300 rated watts and 4100 peak watts.
With a noise rating of 67 dBA (less noisy than an office), the generator features a conventional 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.
Since the H03652 has a somewhat high THD (<25%), it is advisable to not use it for the powering of 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
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 status and activity may be monitored conveniently via the control panel, as it features a convenient meter, which displays 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.
As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).
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: oil, tool kit, propane hose 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 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 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 generators in the 3500-4500 rated wattage range. If you are concerned by weight, one of the champions in the above-mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
- Because this generator emits noise as low as 67 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. 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 Cummins Onan P4500i, whose lowest noise levels reach just 52 dBA.
- Since the H03652 boasts with a run time of around 14 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Predator 4375, boasting with around 16 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. This generator reaches an estimated fuel consumption of 0.36 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned 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 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.
