Description
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 outdoor fairs, festivals or events
- 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 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
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 3650W along with a peak wattage of 4550W. While propane-powered, it provides 3300 rated watts and 4100 starting watts.
The generator features a conventional pull-start mechanism. It is rated for a noise of 67 dBA (less noisy than an office).
As for its running time, the H03652, along with its 5 gallons fuel capacity, can run for around 14 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.36 GPH). If propane is used, it can operate for around 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH).
The H03652 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<25%).
Outlets
The control panel features the upcoming 4 AC outlets:
Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Firman generator is RV Ready.
Portability
The design of the Firman H03652 is a typical, open frame, with the dimensions of L25.7 x W21.8 x H21.6 in, offering support and stability and enabling the possibility of raising it above ground level. The device has been designed for tough environments and demanding outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 113 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.
Features
The control panel of the H03652 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
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: oil, tool kit, propane hose and funnel.
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 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 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.
- The generator can be considered average in its noise for its power category, as it is rated at 67 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 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 autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000X, reaching around 16 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. 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 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.
