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
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals who want to be able to deliver results, even during a power failure
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
The Firman H03652
The dual-fuel technology of the Firman H03652 allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3650W and a starting wattage of 4550W. If propane-powered, it gives 3300 rated watts and 4100 starting watts.
With a noise rating of 67 dBA (less noisy than a normal conversation), the generator features 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 powering of sensitive electronic devices with the H03652 is not recommended due to its relatively high THD (<25%).
Outlets
The control panel features the following 4 AC outlets:
With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready.
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. The device has been designed for tough environments and demanding outdoor use.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 113 pounds. 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
To help you monitor the H03652's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.
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 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.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman H03652 also comes with some accessories: oil, tool kit, propane hose and funnel are included.
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 and therefore, can be used 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 weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
- The generator can be considered average in its noise for its power category, as it is rated at 67 dBA. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of 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. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000X, which is able to run for 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. 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 fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from this interactive chart, when compared to other 3500-4500W generators, the Firman H03652 is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.

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.
