Comparison Table of Firman Generators

Reviews of Firman Generators would not be good without a comparison table. See the table below for details.

Reviews of the Top 5 Best Firman Generators

1. Firman W03083 3000 Watt

This is the first one in our Firman Generators Review article. The W03083 is a famous Firman inverter generator that has 3300 starting watts and 3000 running watts. That’s enough power if you are into RV or looking for a 3000-watt generator.

The generator’s power can handle a 13,500 BTU  air conditioner and a few electrical appliances like microwaves, lightbulbs you may have at home.

Its 1.8-gallon fuel tank can get you up to 8 hours, but it would depend on the lead you have. One thing you need to remember is, you may need to refuel if you operate at a higher load. 

Fortunately, if you plan to operate a basic few devices we have mentioned above like AC, then the W0308 will serve you well without any problem. The W0308 serves your needs with four outlets:

  • 1 x TT-30R 30A 120V outlet
  • 1 x 5-20R Duplex 20A 120v
  • 1 x 12VDV 8.3A
  • A USB port to charge your portable electronic devices like phones.

The generator has a  user-friendly control panel, and the electric start makes it easier to operate. One thing you’ll have to hate about it is that it’s louder than most inverter generator. The manufacturer says that it, it’s noise level is 85dB if you operate at 25% load.

But if you plan to run at a max load, the noise level may be too high. Overall it’s not an awful generator because it performs well. The generator is compact and comes with lots of sound insulation panels.

Since it is an inverter generator, it produces a pure sine wave and has less than 3% Total Harmonic Distortion (THD). In case of emergency, you can use a recoil starter to start the generator.

Besides that, the Firman has parallel connectivity that allows you to use the same generator for dual power. At 100 pounds, the W03083 is a bit heavy for one person to carry, although it has well-placed gripping points and wheels to assist in mobility.

One thing I love about this model is it has features you’ll find in high-end generators like parallel connection parts and remote control starting. 

For that reason it’s safe to say, it beats some high-end inverter generator of the same price.  It matches high-end inverter generators in every way but surpasses them in price.


  • Best inverter generator
  • Four outlets
  • Excellent performance 
  • User-friendly control panel


  • Lots of noise


2Firman P03601 3650 Watt

If you are looking for a Firman conventional generator that you can use at a job site or RV camping. Then the Firman P03601 3650 watts tops the list.

The generator has 4550 starting watts and 3650 running watts. That’s the right amount of energy you need to work with job site electrical tools like air compressors, drills. Or belt sanders. Likewise, you can use it to run essential electrical devices at home in the event of a blackout.

Even if you use it at home, never expect it to backup the whole house. If you want to back up a full house, you’ll need a large generator to power all the devices. 

If you are an RV owner, on the other hand, you’ll find this generator to be sufficient. The reason I say that is because it can handle a 15,000 BTUs AC without any challenge along with the equipment you use in RV.

Depending on how much load you have, the generator can run for 14hours. The time will be shorter if you operate at a 100% load.

One thing you will hate about this generator is it’s heavy to carry and won’t come with a wheel kit. You’ll have to buy the wheel kit separately, which will incur you the extra cost. The wheel will be easy to attach.

The generator also has a whisper series muffler that makes it run at 68 decibels. Thanks to this durable and compact tubular roll cage, this generator will last you years. The generator has the following outlets:

  • 1 TT30R (RV ready)
  • 1 L530R
  • 2 120v Standard (5-20 duplex)

Since it has a low oil indicator, you’ll also get an alert when the oil is little. That way, it protects the engine. Did you know that it has a volt lock?  Its purpose is to ensure clear and consistent power production.

Another feature worth mentioning is the built-in multi-monitor system that tracks how the generator runs and shows the number of voltage you are consuming.


  • Inexpensive
  • Excellent run time


  • Heavy 
  • No wheel kit

3. Firman W01781 2100 Watt

Firman offers the W03082 as an inverter generator to campers, tailgater, and boaters. The generator boast of having 2100 surge watts and 1700 starting watts. That makes it an ideal and sufficient generator for small scale and mid-sized electrical devices like speakers, laptops, phones, and e.t.c.

The Firman W08082 has a built-in muffler that minimizes noises. Although it is not one of the quietest generators on the market, it is behind the top perform like Yamaha EF2000iSV2 or WEN56200i.

As a generator with parallel capability, it can use linked to a second generator for a double the power. Since it is an inverter generator, it produces clean sine waves with less than 3% Total Harmonic Distortion. That means you delicate power appliances using it.

Its light indicator will always tell if the generator is ready, when it’s overloaded and when the oil is level is insufficient. Speaking of security measures, the device has an automatic low oil shut-off, that protects the engine when the fat is low.

Since it comes with the necessary documentation and user manual, it is easy to start this generator. Besides that, it also comes with a lot of accessories such as funnel,  tool kit, and charging cable.

The W01781 is both EPA approved and CARB-compliant, that means you can use it in all 50 states, including California. What’s more, the generator has a spark arrestor. What that means is, you can use it in the forest.

When you compare the W01781 to other generators of 1300-2200W, you’ll find that it has a decent price range. That means it will fit into your budget schedule very well.


  • Parallel connection

4. Firman H03651 4550 Review

If you are looking for a dual fuel generator that operates on both gas and propane. Then the Firman H03651 is ideal for you. Unlike most generators, this one is CARB compliant to mean that residents of California can use it.

The generator also comes with a robust 208cc dual-fuel engine that has standard features like low oil shutdown mechanism and cast iron frame.

Its tank can accommodate up to 5-gallon of gas. That would be enough to get you running for 14 hours if you are not running it at full capacity.

The generator features 4550 starting watts and 3550 running watts, which is so powerful for 30 amp travel trailers. Besides that, this generator can be used at Job Sites. The only thing you need to know is, this generator is not suitable for is 220v MIG welder.

Firman H03651 features a 5.5 feet LPG regular hose. The only thing that will disappoint you is that you have to buy the propane bottle separately.

While on gasoline the generator gives out 3650W as running watts and 4550W as peak wattage. One propane, the generator provides 3300 watts and 4100 starting watt.

The generator is slightly noisy because it provides 75dBA. When it comes to operation, the generator can be quickly started using a simple pull-start mechanism.

Bear in mind that, you should not use this generator to power delicate electrical devices it has a 25% THD. The control panel has 4 AC outlets:

  • Duplex 120V 20A (5-20R) GFCI
  • 120 V 30A (TT-30R) receptacle
  • 120 V 30 A (L5-30R) receptacle

The Firman H03651 features an open-frame design that offers support and stability for raising it from the ground. That’s why it is an ideal generator for outdoors. At 119.5 pounds, the generator is quite heavy to lift and transport it.

But once it is on the ground, you can use the wheel kit for more natural movement. Its control panel houses an army of features such as the voltage, frequency, lifetime hours that are useful for monitoring the generator status and activity.

If you would want to check the fuel gauge on this generator, you are better off using the built-in fuel gauge. When it comes to security, there’s an automatic low oil shut-off and overload protection. That way, you will have peace of mind when using it.


  • Dual fuel generator
  • Perfect for 30 amp RVs
  • CARB compliant


  • Loud
  • Won’t support 220v

It is a recoil starter generator having an output of 4,550 starting watts and 3,650 running watts. Thanks to the Phoenix FatHead Block, its engine which is a 208cc Max pro series will run well and cool the system well.

Given that it only provides 67dB(A) of noise, this generator has been known to be the quietest conventional generator on the market. The addition of the Whisper Series muffler ensures it runs silent most of the time.
