Power & Run Time

The Firman WH02942 in use

The Firman WH02942

The Firman WH02942, equipped with dual-fuel technology and delivering 120V, ensures both power and versatility. Running on gasoline, it delivers a running wattage of 2,900W and a starting wattage of 3,200W. On propane, it provides 2,600 running watts and 2,900 starting watts. In addition, as it is parallel capable (Firman parallel kit (opens in a new tab) not included), this power can be doubled when linked to another similar or compatible unit.

Operating with a noise rating of 58 dBA (less noisy than a conversation at home), this inverter generator offers two starting options: a traditional recoil pull-start mechanism and a straightforward and intuitive electric starter (battery included).

In terms of running time, the WH02942, equipped with a 1.8 gallon fuel tank, is capable of running continuously for up to 10 hours on a full gasoline tank (with fuel consumption estimated at around 0.18 gallons per hour). When utilizing propane, it provides up to 19 hours (estimation based on a 20 lbs tank - propane consumption around 0.25 GPH) of operation.

Thanks to its low <3% Total Harmonic Distortion (THD), the WH02942 produces a clean sine wave output, making it safe for your sensitive electronics when utilizing the AC outlets.

Outlets

The control panel is equipped with the following 3 AC outlets:

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

Furthermore, it showcases 2 DC outlets: there's a 5V USB port allowing you to conveniently charge electronics such as mobile phones and tablets and a 12V 8A receptacle allowing you to easily charge your batteries.

Featuring a TT-30R receptacle (TT for 'Travel Trailer'), this Firman generator is RV Ready, designed specifically for use with recreational vehicles.

Portability

As the Firman WH02942 is an inverter generator, its encased design (L23.2 x W17.8 x H17.9 in) offers more aesthetics than a conventional, open frame product. The generator has a contemporary design, convenient for recreationally generating power.

The 90 lbs of the WH02942's dry weight enables you to use it anywhere you will ever need. In addition, with its set of 2 wheels (⌀5.5") and its folding handle, it may be shifted with ease, once placed on the floor.

The WH02942's control panel

The WH02942's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

In addition to this info, when the oil level is too low, the generator is ready and the generator is on overload, you will be informed by the featured light indicators.

Considering security aspects, the generator boasts an automatic low oil shut-off and an overload protection (circuit breaker), offering peace of mind throughout operation.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman WH02942's package also includes these accessories: tool kit, oil, propane hose, battery charger and funnel.

The Firman WH02942 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman WH02942 compare to inverter generators of similar power (between 2500 and 3500 W).

  • At 90 lbs in dry weight, the Firman WH02942 fits well within the typical weight bracket for inverter generators producing 2500 to 3500 rated watts. Weight-conscious users may find the Pulsar PGD40iSCO appealing, as it is one of the top contenders in this power range, weighing just 46 pounds.
  • At just 58 dBA rated noise level, this inverter generator is positioned as one of the quieter choices among devices delivering similar type and power. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
  • In terms of autonomy, the WH02942 offers up to 10 hours at a 25% load, placing it at the lower range within its type and power range. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 200914, which is able to run for up to 22 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. At a 25% load, the inverter generator consumes an estimated 0.18 gallons of gasoline per hour, falling within the average consumption range of units with similar output. If minimizing fuel usage is one of your key priorities, the Energizer eZV3500P is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.13 gallons per hour.

Price comparison

As you can see from these interactive charts, when compared to other 2500-3500W dual fuel inverter generators, the Firman WH02942 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

Unlike many websites, we did our best to research each of the specs above. That being said, we are not immune to making the occasional mistake or omission. Should you notice any missing or incorrect values, don't hesitate to suggest improvements so we can address the issue.
* Propane runtime is our own estimation, based on a 20 lbs tank and NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs of propane = 1 gal of gasoline.

    Does the noise/sound level vary much when using propane instead of gasoline? We use propane. I’m reworking my sound box, and considering how much effort to put into improving the sound box.

    We purchased online through Costco and had it delivered last year. I thought I would need two units joined together so I ordered two. One had a broken case. Turned out only one was sufficient for our GD 23BHE trailer. Costco and Firman were great about picking up the broken unit. Of course a broken unit should never have been delivered in the first place.

    Thanks for your review.

    + PROS:
    • Propane option ready to go, and is clean enough for us to put the generator under the dining table in the RV/trailer while traveling.
    - CONS:
    • Generally solid

    Great generator.Priced like a 2000w machine, but out put double to those smaller machines.

    Firman stands behind their products.
    I asked and was told that the LT warranty included, the Generator Brushes, Electric Starter motor, and Propane regulator.

    + PROS:
    • Price. Costco Canada has them for 800 CND ,which is about 575 USD.
    • Oh, and LIFETIME parts warranty!
    • Overall quality is great.
    • You can't beat that Value !!
    - CONS:
    • Could be more economical and quieter
