Description
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
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners in need of an emergency backup power for their essentials
- Professionals in need of safely powering high-intensity work or lighting equipment
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
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 3650W along with a peak wattage of 4550W. While propane-powered, it provides 3300 rated watts and 4100 starting watts.
The generator is rated for a noise of 67 dBA (less noisy than an office). Its starting mechanism is based on a conventional 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).
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:
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 design is ideal for rough environments and demanding 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, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman H03652 also comes with several accessories, including: propane hose, funnel, tool kit and oil.
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 Video
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.
- As this generator can emit noise as low as 67 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are one of your priorities, you may be interested in the Cummins Onan P4500i, one of the least noisy generators similarly powerful as this one, rated for 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 Predator 4375, which is able to run for around 16 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.
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.
