Firman Generators Reviewed – Are They A Good Choice in 2022?

Firman generators are a popular low-cost alternative to big expensive brands.

But can you trust these generators? Are they reliable enough?

Following hours of research, we have prepared the following Firman generator reviews to help you make the right decision.

We have shortlisted 5 Firman generators which we personally found out to be the best options.

Firman Generators The Top 5

Firman P03601 3650 Watt

Firman P03601 is a solid portable generator suitable for most of the jobsites or RV camping.

It provides 4550 starting watts and 3650 running watts of power.

That makes it just about right 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 in the event of 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.

If you need a generator for 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 run for 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 the standard set of 120V AC outlets and basic 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 any problems connecting them to the generator.


  • Convenient remote start
  • Long run time
  • High wattage
  • Good price to quality ratio

Firman W03083 3000 Watt

Firman generators - W03083

Firman W03083 is currently one of the most popular Firman generators. This inverter generator has got in total 3300 starting watts and 3000 running watts of power.

This is enough wattage to make it a very reasonable choice for RV.

It should easily handle a typical 13,500 BTU Air Conditioner and a few minor electrical appliances such as a microwave, a set of lightbulbs and a phone charger.

The fuel tank has got a total capacity of 1.8 gallons.

Depending on your circumstances you should be able to run this generator for up to 8 hours. Bear in my mind though that you might need to refuel sooner if you run it at a higher load.

However, if you are only planning to run the aforementioned air conditioner in your RV for the night, Firman W03083 should be able to run it without interruption till the morning hours.

W03083 has got 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.

We find this generator to be very easy 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 manufacturer advertises its noise level as 58dB which is already more than in the case of some of its competitors.

However, 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 generators too and that’s where the company has got quite some room for improvement.

Overall we would say it’s a decent inverter generator. On the other hand, there are other 3000-watt inverter generators costing the similar price and performing a bit better. Champion 3100-watt generator or its dual fuel cousin are some of the prime examples.


  • Best choice for RV
  • Lightweight
  • Inverter Technology
  • Decent price to quality ratio


  • Could be slightly quieter

We find this generator to be very easy to operate thanks to its user-friendly control panel and the electric start.

One thing we dislike about this generator is that it’s quite heavy and loud at higher loads.

However, that won’t be a major issue at all 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.

Albeit a bit on the heavier side, the generator is quite easy to move around.

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

The remote start works flawlessly and is one feature of this generator we love the most.

The manufacturer claims the remote start works up to 168 feet away, however, in reality, you might want to stand a bit closer to the generator.

Overall this is a very good generator for a construction job.

RV owners would also be happy with it as it can easily handle pretty much all important RV equipment such as ACs, lights, refrigerators etc.

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

This is one of the inverter generators being on offer by Firman. It is primarily designed for such uses as 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 single mid-sized electrical device at a time or a few portable electronics such as speakers, laptops, phones etc.

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 generator on the market and is a bit behind some of the top performers on this matter such as Yamaha EF2000iSv2 or WEN56200i.
