Description
This ultimate generator has it all! The FIRMAN P03631 generator stands alone. Equipped with 3650 running watts, 4550 starting watts and 120/240V power, this monster has a little bit of everything.
Zoom on the Firman P03631
To sum up, the Firman P03631 is a portable generator tailored for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in outdoor fairs, festivals or events
- 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 subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.
Power & Run Time
The Firman P03631 is powered by a 208 cc Firman Max-Pro Series OHV 4-stroke engine with cast iron sleeve. It delivers 120/240V, runs on gasoline and offers a running wattage of 3,650W as well as a peak wattage of 4,450W.
Operating with a noise rating of 75 dBA (just slightly more noisy than a shower), this generator offers two starting options: a conventional pull-start mechanism and a hassle-free and practical electric starter (battery included). For additional convenience, the P03631 may also be remotely started (key fob included).
Thanks to a fuel capacity of 5 gallons, the P03631 can operate for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).
The powering of sensitive electronic devices with the P03631 is not recommended due to its high THD (<25%).
Outlets
The control panel is equipped with the following 4 AC outlets:
Moreover, it boasts 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease and two 5V USB ports (USB-A) ensuring convenient charging of devices like mobile phones and tablets, for connectivity on the go.
Featuring a TT-30R receptacle (TT for 'Travel Trailer'), this Firman generator is RV Ready, designed specifically for use with recreational vehicles. In addition, since it features a twist-lock L14-30R receptacle, the P03631 is tailored to be transfer switch ready, making it easy to connect it to your breaker box for home power support during outages.
Portability
At L24.8 x W21.7 x H21.7 in, the Firman P03631 boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The design is ideal for rough environments and demanding outdoor use.
Despite its weight of 119.5 lbs, the generator is still considered 'portable,' meaning it is movable, although its heftiness may restrict portability in certain environments or require additional considerations for transportation and setup. 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 P03631's control panel
The control panel of the P03631 includes a convenient meter, providing voltage, frequency, and lifetime hours data, helpful for the monitoring of its status and activity. To offer you even more control and easy operation during nighttime, the panel is LED-lit.
In addition to this info, the generator's light indicator provides visual feedback when its oil levels are insufficient.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
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).
The P03631 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 P03631, the following accessories are also included: tool kit, funnel, key fob and oil.
The Firman P03631 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman P03631 compare to generators of similar power (between 3500 and 4500 W).
- At 119.5 lbs dry, the Firman P03631 is consistent with the standard weight profile for devices ranging from 3500 to 4500 rated watts. Weight-conscious users may find the WEN 56432iX appealing, as it is one of the top contenders in this power range, weighing just 52.9 pounds.
- If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 75 dBA can be considered somewhat noisy. If you value reduced noise levels, the Westinghouse iGen5000DF could be worth considering. It's one of the quietest generators in its power range, rated at 52 dBA.
- At 50% load, the P03631 boasts a higher run time than most similarly powerful products, reaching around 14 hours. If prolonged run time is essential to your needs, you could consider the NorthStar c5500, which offers one of the highest autonomy among devices with similar power output, lasting around 15.1 hours.
- Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. 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 wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the Westinghouse iGen5000DF, which has an impressively low fuel consumption of 0.23 GPH.
Price comparison
As you can see from these interactive charts, when compared to other 3500-4500W generators, the Firman P03631 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
