Firman P03601 3650 Watt
Firman P03601 is a solid portable generator suitable for most job sites or RV camping.
It provides 4550 starting watts and 3650 running watts of power.
That makes it suitable for powering electrical tools such as air compressors, drills, or belt sanders.
You could also use it to run the most crucial devices in your home during a power outage.
Don’t expect to use it as a complete backup supply, though. You would need a much larger generator to power multiple large devices at your home.
The 10,000-watt Firman H08051 is the best choice for a home.
This 10,000-watt Firman generator would be the best choice for a home. It’s the right fit if you live in Canada.
If you need a generator for your RV, you will find the Firman P03601 perfectly sufficient. P03601 can handle a 15,000 air conditioner without problems. The same applies to other equipment you might want to run in the AC (as long as you don’t try to turn on everything at once).
Depending on the load, the generator can last up to 14 hours. This time is bound to significantly shorter if you run the generator at a 100% load.
Firman P03601 has got a simple and user-friendly design. It has a standard set of 120V AC outlets and a primary interface, including the low oil level indicator.
Note that this generator is quite heavy to carry around. Sadly, you need to order the wheel kit separately, which is quite a nuisance. On the positive side, the wheels are easy to attach, and you won’t have problems connecting them to the generator.
- Convenient remote start
- Long run time
- High wattage
- Good price-to-quality ratio
- A bit heavy
Firman W03083 3000 Watt
Firman W03083 is currently one of the most popular Firman generators. This inverter generator has 3300 starting watts and 3000 running watts of power.
This is enough wattage to make it a reasonable RV choice.
It should easily handle a typical 13,500 BTU Air Conditioner and a few minor electrical appliances such as a microwave, lightbulbs, and phone charger.
The fuel tank has got a total capacity of 1.8 gallons.
You should be able to run this generator for up to 8 hours, depending on your circumstances. However, remember that you might need to refuel sooner if you run it at a higher load.
However, suppose you only plan to run the air above conditioner in your RV for the night. In that case, Firman W03083 should be able to run without interruption till the morning hours.
W03083 has several outlets: 1 x TT-30R 30A 120V outlet, 1 x 5-20R Duplex 20A 120V, 1 x 12VDV 8.3A, and finally, the USB port for charging portable electronics.
This generator is straightforward to operate thanks to its user-friendly control panel and the electric start.
One thing we dislike about this generator is that it’s louder than some other inverters.
The manuf lecturer advertises its noise level as 58dB which is already more than some of its competitors.
HoweTherefore, this is the sound level at 25% load. The generator can become much louder if you run it at the max load.
The noise level is an issue with many other Firman genera. That’s where the company has room for improvement.
Overall we would say it’s a decent inverter generator. On the other hand, other 3000-watt inverter generators cost a similar price and perform better. Champion 3100-watt generator or its dual fuel cousin are some of the prime examples.
- Best choice for RV
- Lightweight
- Inverter Technology
- Reasonable price-to-quality ratio
- It could be slightly quieter
The generator delivers 4550 starting watts and 3650 running watts of power. This is enough power for emergencies and constant use. The generator will e, efficiently run trefrigeratorshofreezers, and equipment, including refrigerators, freezers, and lighting circuits. The fuel tank has got a total capacity of 5 gallons. You should be able to run this generator for up to 14 hours, depending on your circumstances. The control panel of P03612 features several outlets, each designed for various purposes. These include a 1 L14-30R Twistlock 30A-120/240VAC, 1 x TT-30R 30A-120VAC and a 5-20R Duplex 20A-120VAC outlet. This generator is straightforward to operate thanks to its user-friendly control panel and the electric start. One thing we dislike about this generator is that it’s pretty heavy and loud at higher loads. However, that won’t be a significant issue if you plan to use it mainly as a home backup source of power or at work. Overall, if you need a mid-sized 4000-watt generator for home or work – this Firman generator won’t disappoint.Firman P03612

This is thanks to the heavy-duty wheels and a comfortable handle.

It sells comparatively cheaper than many other generators, offering good quality.

Firman W01781 2100 watt
This is one of the inverter generators being on offer by Firman. It is primarily designed for camping, boats, or tailgating.
It has 2100 surge watts and 1700 starting watts.
That makes it optimal for small-scale use and sufficient to power one mid-sized electrical device at a time or a few portable electronics such as speakers, laptops, phones, etc.
There are enough outlets to handle all these – 1 x 5-20R Duplex 120V 20A outlet, 1 x 12V (suitable for battery charging cables), and 1 x USB port.
You could use it to work tools like chainsaws or drills unless man W01781 has a 9-gallon tank. Unless you constantly use the generator at total capacity, it should run without interruptions for anywhere between 9 to 12 hours.
It is not very heavy – at 51.6 lbs, it is reasonably easy to carry around.
Firman W01781 comes equipped with a built-in muffler which helps in minimizing the noise. However, this is certainly not the quietest generation performer, some of the top performers, such as Yamaha EF2000iSv2 or WEN56200i.
- Lightweight
- Cheap
- Not the quietest
Firman H03651 3650 Watt
Firman H03651 is a dual-fuel generator that operates on g, as, and propane.
It is entirely CARB compliant meaning that even the residents of California – the state with the strictest environmental measures – can legally use it there.
It has a solid 208cc dual-fuel engine with standard features such as a low oil shutdown mechanism and cast iron frame.
The tank is not very large – it can house up to 5 gallons of gas.
This would be enough to run the generator continuously for up to 14 hours to run it at the total output and always attempt to run it at the entire production.
The generator has got 4550 starting watts and 3650 running watts, making it powerful enough for moderate-size 30-amp travel trailers.
You can also use it at most job sites (unless you plan to run a 220V MIG welder – this generator is unsuitable for these).
