Description
The FIRMAN WH02942 Inverter generator features 3200 starting watts and 2900 running watts. Power is supplied by our Max Pro Series 171cc FIRMAN engine which runs cool and efficient thanks to its Phoenix Fat Head Block. Our Whisper Series muffler keeps the Wh02942 running a quiet 58 decibels – well below the standards set by the National Parks Service, and our spark arrester has been approved by the USDA Forest Service. The 1.8-gallon fuel capacity provides a whopping 9 hours of run time. Starting is simple with the reliable FIRMAN electric start system.
Zoom on the Firman WH02942
In a nutshell, the Firman WH02942 is a quiet and compact portable inverter generator mostly geared towards:
- DIYers who wish to improve their efficiency with tools
- Homeowners in need of an emergency backup power for their essentials
- Camping and tailgating hobbyists looking for a portable power source
- RV travellers wishing to enhance their freedom and nomad lifestyle
The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.
Power & Run Time
Featuring dual-fuel technology, the Firman WH02942 provides 120V, and offers both power and versatility. Running on gasoline, it delivers a running wattage of 2,900W and a starting wattage of 3,200W. When propane-powered, it offers 2,600 running watts and 2,900 starting watts. Furthermore, its parallel capability (Firman parallel kit (opens in a new tab) not included) allows power output to double when connected to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.
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 user-friendly and efficient electric starter (battery included).
In terms of its run time capability, the WH02942, furnished with a 1.8 gallon fuel tank, can maintain operations for up to 10 hours on a full tank of gasoline (with fuel consumption averaging 0.18 gallons per hour). It also provides up to 19 hours (estimation based on a 20 lbs tank - propane consumption around 0.25 GPH) of operation with propane.
The WH02942 generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.
Outlets
The control panel includes the following 3 AC outlets:
It also sports 2 DC outlets: there's a 5V USB port enabling convenient charging of devices like mobile phones and tablets and a 12V 8A receptacle making battery charging a breeze.
Thanks to its TT-30R receptacle (TT meaning 'Travel Trailer'), this Firman generator is RV Ready, ready to power your recreational vehicle with ease.
Portability
With an inverter generator design, the Firman WH02942 features a closed construction (L23.2 x W17.8 x H17.9 in), enhancing aesthetics and ensuring reduced noise levels, offering a distinct advantage over standard, open frame generators. The design follows the contemporary trends and is perfect for recreationally generating power.
Weighing 90 lbs, the WH02942 is practical, ensuring it can follow you wherever power is required. 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 and its control panel include a convenient meter, showing voltage, frequency, and lifetime hours metrics. This feature comes handy when monitoring its status and activity.
In addition to this info, the device’s light indicators will display if its oil levels are insufficient, the generator is on overload and the generator is ready.
As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman WH02942 also comes with several accessories, including: battery charger, funnel, oil, tool kit 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).
- With a dry weight of 90 lbs, the Firman WH02942 sits comfortably within the expected weight range for inverters generating 2500 to 3500 rated watts. If weight is an important consideration for you, the Pulsar PGD40iSCO stands out as one of the top contenders in this power category, with a dry weight of 46 pounds.
- With noise levels starting from 58 dBA rating, this inverter generator stands out as one of the quieter options among products of similar type and power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU3000iS with only 50 dBA.
- Regarding its runtime, the WH02942 operates for up to 10 hours at a 25% load, positioning it at the lower spectrum among comparable inverters. If extended autonomy is what matters most to you, the Champion 200977 could be an excellent choice, offering one of the longest run times among units in its power category, reaching up to 22 hours.
- Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. 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 0.14 GPH, the Honda EU3200i is a device you could look out for.
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.

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.
