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).
- At a weight of 90 pounds, the Firman WH02942 places in the expected weight range of the inverter generators in the 2500-3500 rated wattage range. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGD40iSCO, with a dry weight of just 46 pounds.
- Rated at a lowest possible noise level of 58 dBA, this inverter generator positions itself amongst the more quiet of the products of similar type and power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
- As for its runtime, the WH02942 runs for up to 10 hours at a 25% load, placing it towards the low end among comparable inverters. If run time is one of your main concerns, the Champion 200977 could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting up to 22 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator has an estimated fuel consumption of roughly 0.18 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. To prioritize fuel savings, we advise considering the Energizer eZV3500P, which stands out for its gasoline efficiency, consuming just 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.

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.
