Firman 2000 Watt Generator Review

Before starting this Firman 2000 Watt Generator Review, we also test a few other inverters. Including A-iPower SUA2000i, Briggs & Stratton P2400, and Honda EU2200IC. It’s Quiet, pretty strong, and with good power. It’s hard to beat for the price, and it’s just as good as much more expensive units.

The Firman 2000 inverter generator delivers up to 2000 watts of power, making it an excellent choice for use in an RV, at a campsite for small power appliances, or home because it only weighs 44 pounds.

Firman can be relied upon to supply you with long-lasting generators. Portable and light, this model is an excellent option for travelling. You may quickly move it from one location to another in a power outage. When turned on, the Firman W01781 inverter produces 2100 watts yet only uses 1700 watts while running.

Because of the engine’s 80cc displacement, the generator stays cool to the touch even at maximum output. The Phoenix Fat Head Block ensures this generator’s efficiency. Regardless of the conditions, this is the best 200 Watt generator.

This model has a Whisper Series muffler that reduces the noise level to 54 decibels, making it ideal for those who don’t want their generator to be too noisy. The 1.2-gallon gasoline capacity ensures a 12-hour runtime. How much more do you require? Also worthy of mention is the first-pull recoil mechanism of the Firman First Pull:

Despite its small size, this model is built to last, and the ergonomic handle makes it a breeze to hold and operate.

How much power can we get, and How much time can this Generator run?

Powered by an 80cc Firman Max-Pro Series OHV 4-stroke petrol engine, the Firman W01781 design has a continuous output of 1700 W and a peak output of 2100 W when connected to a 120 V outlet. A second compatible device can double the output power, but the Firman Parallel Kit (opens in a new tab) must be purchased separately.

The inverter generator uses a conventional machine with a noise level of 54 decibels (dBa) (slightly louder than rain).

The W01781 can run for up to nine hours on a full gas tank (fuel consumption of about 0.1 GPH).

The W01781 generates a pure sine wave and achieves a THD of 3%, making it safe to connect electronic devices with high sensitivity to wall outlets (THD).

Number of Outlets

The following two sockets can be found on the control panel:

  • 2 – 120V 15A,
  • 1 – 12V 5A DC,
  • 5V 2.1A USB Port

Portability of the Generator

The Firman W01781’s closed inverter generator design (L20 x W12.1 x H16.7 inches) gives it a more attractive appearance than an open-frame generator would typically possess. This design can generate recreational electricity in the most efficient manner possible.

The W01781 is a lightweight, portable generator because it weighs just 45.9 pounds. It should be easy to move for one person, allowing them to take advantage of the on-the-go power. With a handle incorporated into the case, you can easily carry it, enhancing your comfort.

Features we like about this machine.

By looking at the conspicuous indicators, you’ll know if the generator is overloaded, the oil is low, or if it’s ready. This device has an automatic low oil shut-off for your safety and peace of mind when using it.

The Firman W01781 also comes with a few accessories, such as battery charging cords, a funnel, oil, and a tool kit, to help you get up and running quickly.

Warranty information

The Firman W01781 has a three-year warranty. It is possible that this guarantee does not cover all generator components. For additional information on Firman generator warranties, please see their Warranty Policy (opens in a new tab). Contacting their customer service is another option.

Firman W01781 comparison with other

You can see how the Firman W01781’s major specifications compare to other generators of the same power by looking at this comparison (between 1500 and 2500W).

  • The Firman W01781 weighs only 45.9 pounds, making it one of the lightest generators in the 1500-2500 rated power range. Honda EU2200IC weighs 46.5 pounds, which makes it a contender in this category if weight is an issue.
  • The predicted noise level for this inverter generator is evaluated at 54 decibels (dBA), which is about typical for its power range. The Honda EU2200IC, rated at 48 dBA, is one of the quieter generators of comparable power, which may interest you if noise emission is a concern.
  • The W01781s run up to 12 hours at half load. It’s run longest among others.

  1. Works as expected. I bought this unit to power my circular saw and recharge the battery packs for other tools. It runs very quiet and works as expected. I did try it on my rv 13.5k a/c unit, but the breaker tripped immediately. I’m still satisfied to use it just for the fan and charging system.

  2. Eats & Sweets by Lai says:

    Quiet but not as powerful as expected. It is light and quiet, but the power is sometimes inconsistent. It somewhat does the job for me but it is limited. In general it is a good product for the price compared to a Honda. The customer service experience I had was disappointing.

  3. Just right. I purchased 2 of these and paired them together to run my rv when I’m off the grid. They do a great job. I bought because of wieght i can handle. 1 4000 w was too heavy.

  4. As expected. The supplied oil matched the stated capacity so when I filled it, it overflowed a bit a made a mess. Dip stick is near the horizontal so visual checking is difficult. Started easily and put under full and medium load for a break in. The manual is good with lots of helpful info. Havent had any long term use yet but suspect it will be fine.Satisfied with this purchase.

  5. Almost a 5 star!! I purchased this unit for our yearly moose hunting trip to our remote cabin. Was excited to try it out but after opening the box I found the accessory kit, oil, plug wrench, 12 volt charging cable and owners manual were missing. Also the black plastic cover above the spark plug was also missing. That was a little frustrating. The generator itself worked great. After the initial break in it was started and run for 6 days straight, 24 hours a day. It ran our refrigerator and a dozen lights no problem. It did chug a little when the refrigerator cut in but pulled through and was never a problem would have been 5 stars if the missing pieces were in the box!

  6. Great Generator. Just purchased unit. Easy to start. Pretty quite compared to some. Don’t like the fact you need to take panel off each time to check oil. Sorry after awhile screws wear out. Wished it had a fuel gauge or someway to tell how much fuel you have.

  7. YB Quebec says:

    Great value for your money ! Very satisfied with this generator…so satisfied that we bought a second one to be used in parallel mode. We love the fact that it is lightweight, comparatively silent and not a gas guzzler. Walmart offered the best bargain price for this product. We had shopped around a lot before deciding to buy ours at Walmart — one in store and the other at a cheaper price online at (my wife was ecstatic to pay hers a lot less than mine ). Our only grudge was that Firman did not include a gas level indicator for this generator — filling up the gas tank is an adventure each time.

  8. DAVID ROUGE says:

    NICE AFFORDABLE GENERATOR. bought this generator to run 18 ft camper works like a charm . will not run ac but new this when i bought it charges battery and microwave . it is very quite looks well made. time will determine reliability but so far so good . great delivery service would buy again thank you

  9. Good price for what you get. Just had it for a week or so and it works well, and starts easily. Got in case of a power failure and looks like it will only run 1 fridge at a time but will just circulate between them. The startup is what is the trouble but tested it with a heat gun at 1500 watts and runs pretty good.

  10. Genset. Heavier than i thought. Very robust.
    Quiet and good standby 110v unit.
