In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.
Power & Run Time
The Firman WH02942
Delivering 120V, the Firman WH02942 is enhanced by dual-fuel technology, providing power and versatility. Running on gasoline, it boasts a running wattage of 2,900W and a starting wattage of 3,200W. Alternatively, when propane-powered, it delivers 2,600 running watts and 2,900 starting watts. Moreover, the parallel capability (Firman parallel kit (opens in a new tab) not included) enables doubling of power output when paired with another similar or compatible unit, providing increased energy capacity and versatility for a wide range of needs.
The inverter generator, rated for a noise of 58 dBA (less noisy than a conversation at home), provides flexibility in starting, offering both a standard recoil pull-rope starting mechanism and an intuitive and practical electric starter (battery included).
The WH02942, with a fuel capacity of 1.8 gallon, reaches a run time of up to 10 hours utilizing gasoline (fuel consumption around 0.18 GPH). Alternatively, it can reach a run time of up to 19 hours (estimation based on a 20 lbs tank - propane consumption around 0.25 GPH) with propane.
The WH02942 generates a clean sine wave with <3% Total Harmonic Distortion (THD), ensuring minimal electrical noise and fluctuations. This feature makes it ideal for powering sensitive electronics, providing stable and reliable AC power through the outlets.
Outlets
The control panel provides the upcoming 3 AC outlets:
Furthermore, it showcases 2 DC outlets: there's a 5V USB port with which you may charge electronics, for example mobile phones or tablets, conveniently and a 12V 8A receptacle allowing you to easily charge your batteries.
This Firman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').
Portability
As an inverter generator, the Firman WH02942 showcases a closed design (L23.2 x W17.8 x H17.9 in), enhancing aesthetics and ensuring quieter operation compared to conventional, open frame models. This type of design is the most modern and convenient way to recreationally generate power.
Weighing 90 lbs, the WH02942 is easily handled, ensuring it can go wherever your power needs are. Furthermore, thanks to its set of 2 wheels (⌀5.5") and its folding handle, shifting the generator once it's placed is a breeze.
Features
The WH02942's control panel
The control panel of the WH02942 is equipped with a convenient meter showing you voltage, frequency and lifetime hours, aiding in monitoring its status and activity.
In addition to this info, some light indicators allow you to instantly see if the generator is overloaded, its oil levels are insufficient and the generator is ready.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
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: oil, battery charger, tool kit, funnel and propane hose.

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).
- Since the generator weighs in at a dry weight of 90 lbs, the Firman WH02942 belongs in the expected weight range for inverters which can produce between 2500 and 3500 rated watts. If weight is a key factor for your needs, the Pulsar PGD40iSCO is noteworthy for being one of the top contenders in this power range, with a dry weight of 46 pounds.
- This inverter generator offers a rated noise level of 58 dBA, placing it among the quieter alternatives in its type and power category. If you'd like a less noisy alternative, the Honda EU3000iS is a strong contender. It boasts a noise rating of 50 dBA, placing it among the quietest generators in its power category.
- As far as autonomy is concerned, providing up to 10 hours of runtime with a full tank at a 25% load, the WH02942 falls into the low end in comparison with other inverters of a comparable power output. If prolonged run time is essential to your needs, you could consider the Champion 200977, which offers one of the highest autonomy among devices with similar power output, lasting up to 22 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. The inverter generator utilizes approximately 0.18 GPH of gasoline at a 25% load, placing it within the typical range of fuel consumption seen in products of comparable wattage. If gasoline efficiency is at the top of your list, you may want to have a look at the Energizer eZV3500P, which has great fuel efficiency, with a gas 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 average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

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.

User Reviews
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.
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.
