Firman 4550 Generator with Remote Start

Firman generator with remote startThis is one the most popular Firman generators up to date.

It has a very convenient remote start which makes it stand out of the competition.

Few other generators come with a remote start making this Firman gen a really interesting choice.

Its engine produces 4550 starting watts and 3650 running watts of power.

To give you a better idea of what you can run with it these are some the tools and appliances this generator could power:


  • 10″ Table Saw 1
  • HP Air Compressor
  • Bench Grinder
  • Circular Saw

The Firman 3650/4550W has got a 5-gallon fuel tank.

It can last for up to 14 hours at 50% load.

This makes it more fuel-efficient than a lot of competitors.

The generator is fully CARB compliant – California residents can use it legally without problems.

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 really 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 really good quality.

If you need a generator for an emergency home backup power supply – you should also have a look at this Firman generator.

Firman W03083 3000 Watt

Firman generators - W03083Firman 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 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 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 not a bad inverter generator. On the other hand, there are other 3000-watt inverter generators costing the similar price and performing significantly better. Champion 3100-watt generator or its dual fuel cousin are some of the prime examples.

  • Suitable for RV
  • Decent price to quality ratio
  • Loud
  • Struggles a lot in colder temperatures

Firman P03601 3650 Watt

One of the most popular firman generators - P03601

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

It has 4550 starting watts and 3650 running watts of power. This 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 a complete backup supply though. You need a much larger generator to power multiple large devices at your home.

RV owners, on the other hand, could find it 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 100% load.

Firman P03601 has got a simple design. When it comes to any interesting unique features, there is nothing to write home about. If has the standard 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. At least the wheels are easy to attach and you shouldn’t have any problems connecting them to the generator.

  • Inexpensive
  • Decent run time
  • Automatic voltage regulator
  • Wheels need to be purchased separately
  • Heavy

One of a few inverters offered by Firman Generators - W03082

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.

This 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.

There are enough outlets to handle all of these – 1 x 5-20R Duplex 120V 20A outlet, 1 x 12V (suitable for battery charging cables) and 1 x USB port.

You could also use it to run some work tools like chainsaws or drills.

Firman W01781 has got a 9-gallon tank. Unless you constantly use the generator at its full 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 generator on the market and is a bit behind some of the top performers on this matter such as Yamaha EF2000iSv2 or WEN56200i.

  • Lighweight
  • Cheap
  • Not the quietest
