Description
Zoom on the Firman H03655
In a few words, the Firman H03655 is a portable generator perfectly suited for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
The Firman H03655
Thanks to its dual-fuel technology, the Firman H03655 delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3,650W and a peak wattage of 4,550W. When propane-powered, it has 3,300 rated watts and 4,100 peak watts.
The generator is rated for a noise of 67 dBA (less noisy than an office). Its starting mechanism is based on a manual recoil starter system.
Regarding its running time, the H03655, 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 H03655 exhibits a THD of less than 25%, which is high, it is best avoided for powering sensitive electronic devices.
Outlets
The control panel features the following 4 AC outlets:
The inclusion of a TT-30R receptacle (TT for 'Travel Trailer') makes this Firman generator RV Ready, ideal for providing power to recreational vehicles.
Portability
Measuring L25.7 x W21.8 x H21.6 in, the classic open frame build of the Firman H03655 delivers stability and easy maintenance access to components, facilitating air circulation. The design is ideal for rough environments and demanding outdoor use.
Since the generator weighs 112 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Despite the restricted maneuverability, its wheel kit (⌀8") and its folding handle provides a solution, allowing for convenient shifting once the generator is positioned on the ground.
Features
The H03655's control panel
Integrated into the control center of the H03655 are a convenient meter, displaying voltage, frequency, and lifetime hours information, facilitating the monitoring of its status and activity.
Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.
Regarding security, the generator comes with an automatic low oil shut-off and an overload protection (circuit breaker), providing peace of mind during operation.
The H03655 also benefits from Firman’s CO Alert carbon monoxide shutdown, which automatically shuts down the engine when harmful levels of carbon monoxide accumulate around the generator or a CO Alert fault occurs.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman H03655, the following accessories are also included: funnel, propane hose, oil and tool kit.
The Firman H03655 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman H03655 compare to dual fuel generators of similar power (between 3500 and 4500 W).
- At a dry weight of 112 pounds, the Firman H03655 is one of the heavier dual fuel devices which can produce between 3500 and 4500 running watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGX5250BiXCO, with a dry weight of just 64 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 level is one your key decisive factors, you may find the Westinghouse iGen5000DF appealing. It's rated at 52 dBA, making it one of the quietest generators in its power range.
- At 50% load, the H03655 boasts a higher run time than most similarly powerful dual fuel products, reaching around 14 hours. If run time is one of your main concerns, the Westinghouse iGen5000DF could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting around 15 hours.
- Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. The generator burns fuel at a rate of around 0.36 GPH when running at a 50% load, which is consistent with the average fuel usage of models of comparable power output. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen5000DF, which has a fuel consumption of only 0.23 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from these interactive charts, when compared to other 3500-4500W dual fuel generators, the Firman H03655 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

- In the expected price range
- Dual fuel
- CO Alert technology
- Several accessories included
- RV Ready
- High run time
- Acceptable noise (67 dBA)
- Decent fuel efficiency
- No electric start

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.
