Description
Zoom on the Firman WH02942
In a nutshell, the Firman WH02942 is a quiet and compact portable inverter generator mostly geared towards:
- Amateur DIY lovers
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Camping and tailgating hobbyists looking for a portable power source
- RV travellers looking for even more independence
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Firman WH02942
Thanks to its dual-fuel technology, the Firman WH02942 delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 2900W and a peak wattage of 3200W. When propane-powered, it has 2600 rated watts and 2900 peak watts. Additionally, as the generator is parallel capable (Firman parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.
Enjoying a noise rating of 58 dBA (less noisy than a refrigerator), this inverter generator can be started thanks to a simple traditional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included).
With a fuel capacity of 1.8 gallon, the WH02942 can operate for up to 10 hours using gasoline (fuel consumption around 0.18 GPH), or for up to 19 hours (estimation based on a 20 lbs tank - propane consumption around 0.25 GPH) using propane.
Sensitive electronics can be safely plugged in the AC outlets, as the WH02942 produces a clean sine wave, with a <3% Total Harmonic Disruption (THD).
Outlets
The control panel includes the following 3 AC outlets:
In addition, it provides 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.
With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready.
Portability
The Firman WH02942 is an inverter generator and has an encased design of the following dimensions: L23.2 x W17.8 x H17.9 in. Thus, it is more aesthetical than conventional, open frame products. This type of design is the most modern and convenient way to recreationally generate power.
The 90 lbs of the WH02942's dry weight enables you to use it anywhere you will ever need. Additionally, it can be easily moved with the help of its wheel kit (⌀5.5") and its folding handle, once it is on the ground.
Features
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, the device’s light indicators will display if the generator is ready, the generator is on overload and the oil level is too low.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman WH02942 also is packed along with the following accessories: funnel, battery charger, propane hose, oil and tool kit.
Emissions
The Firman WH02942 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.
Moreover, it features a spark arrestor and therefore, can be used in forested areas.

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 generators of similar power (between 2500 and 3500 W).
- Weight-wise, the Firman WH02942 has only 90 lbs, which renders it one of the lighter generators which produce 2500 to 3500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
- Since this inverter generator is rated for a lowest possible noise of 58 dBA, it can be considered as one of the more quiet of the products generating similar power. If noise emissions are one of your priorities, you may be interested in the Honda EU3000iS, one of the least noisy generators similarly powerful as this one, rated for 50 dBA.
- Autonomy-wise, with up to 10 hours on a full tank at a 25% load, the WH02942 is on the low end when compared to other generators of a similar power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 200954, as it provides 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 average fuel consumption among comparably powerful devices, as it reaches 0.18 GPH (gallon per hour) at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3200P is a device you should look out for.
Price comparison
As you can see from this interactive chart, when compared to other 2500-3500W 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.
