Zoom on the Firman H03651
In summary, the Firman H03651 is a portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- 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 be able to deliver results, even during a power failure
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 H03651
The dual-fuel technology of the Firman H03651 allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3,650W and a starting wattage of 4,550W. If propane-powered, it gives 3,300 rated watts and 4,100 starting watts.
Enjoying a noise rating of 67 dBA (less noisy than background music), this generator can be started thanks to a conventional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included).
With a fuel capacity of 5 gallons, the H03651 can operate for around 14 hours at 50% load using gasoline (fuel consumption around 0.36 GPH), or for around 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH) using propane.
The quite high THD (<25%) of the H03651 makes it unsuitable for powering sensitive electronic devices.
Outlets
The control panel includes the following 4 AC outlets:
This Firman generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').
Portability
The Firman H03651 has a conventional, open frame design, of the following dimensions: L24.7 x W21.8 x H21.6 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.
Since the generator weighs 119.5 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). However, this lack of maneuverability is compensated by its wheel kit (⌀8") and its folding handle, with which you can conveniently shift it, once it's on the ground.
Features
The H03651's control panel
The H03651's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
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).
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman H03651's package also includes these accessories: propane hose, tool kit, oil and funnel.
Emissions
The Firman H03651 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, making it usable in forested areas.
Product Video
The Firman H03651 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman H03651 compare to dual fuel generators of similar power (between 3500 and 4500 W).
- As its dry weight is 119.5 pounds, the Firman H03651 is one of the heavier of the dual fuel products which can generate 3500 to 4500 running watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the WEN DF402iX, with a dry weight of just 66.1 pounds.
- The generator can be considered average in its noise for its type and power category, as it is rated at 67 dBA. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500DF, 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 H03651 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 Westinghouse iGen4500DF, which is able to run for around 15 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. 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 iGen4500DF, which boasts with a gas consumption of only 0.23 GPH, may be the right generator for you.
Price comparison
As you can see from this interactive chart, when compared to other 3500-4500W dual fuel generators, the Firman H03651 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

How much oil does it take? (Asked December 14, 2019)
The oil capacity is 20.3 oz.
When connecting this generator to propane with the supplied hose,.....do I just connect the propane tank with the hose to the generator? Is the propane regulator built into the generator? Or do I need to buy a separate regulator? Thank you. (Asked December 10, 2020)
The regulator is included with the LPG hose.
