Description
The Firman WH02942 has 120V and a lot of power and versatility thanks to its dual-fuel technology. When powered by gasoline, it has a running wattage of 2,900W and a maximum wattage of 3,200W. When powered by propane, it has a rated 2600 watts and a peak of 2900 watts. Also, the device can work in parallel (but does not come with a Firman parallel kit), so it can be linked to a similar or compatible unit for more power. The noise level of the inverter generator is set at 58 dBA (less noisy than a conversation at home). It has both a traditional pull-start mechanism and a simple but elegant electric starter (battery included). The WH02942, which has a 1.8-gallon fuel tank, can run for up to 10 hours on gasoline (fuel consumption is approximately 0.18 GPH). If you use propane instead, it can run for up to 19 hours (based on an estimate of a 20-lb tank and 0.25 GPH of propane use per hour). The WH02942 makes a clean sine wave with a Total Harmonic Distortion of 3%, so it’s safe to plug sensitive electronics into AC outlets (THD).
Outlets
On the control panel, there are 3 AC outlets: a duplex 120V 20A (5-20R) outlet and a 120V 30A (TT-30R) outlet. It also has 2 DC outlets: a 5V USB port that makes it easy to charge devices like cell phones and tablets, and a 12V 8A receptacle that makes it easy to charge your batteries. This Firman generator is ready for an RV because it has a TT-30R (TT stands for “Travel Trailer”) receptacle.
Features
The WH02942’s control panel has a handy meter that shows voltage, frequency, and lifetime hours so you can keep an eye on its status and activity. In addition to this information, the device’s lights will show if the oil level is too low, if the generator is overloaded, or if it is ready to use. For safety, the generator has an automatic low oil shut-off and an overload protection (circuit breaker), so you can use it without worrying. Along with basic instructions and an owner’s manual, which will help you start the generator right away, the Firman WH02942 comes with a propane hose, oil, tool kit, funnel, and battery charger.
Mobility
The Firman WH02942 is an inverter generator. It has a case that is L23.2 in, x W17.8 in, x H17.9 in, So, it looks better than most other products with open frames. The design shown here is in line with the latest trends and is great for easy and fun use. The WH02942 can go anywhere because it only weighs 90 pounds. Also, its two wheels (diameter: 5.5 “Once it’s on the ground, you can easily move it with its folding handle.

- We compared more than 500 portable generators at 50% load. We found that there is “skewed right” distribution for the difference between 50% load and 25% load and the median comes at 1.43. With this number we converter all the 25% load runtime to 50% load. Same with the propane efficiency, where median is 1.38.
- For some generators where propane runtime was not given, we used NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs. of propane = 1 gal of gasoline. All propane runtime is for 20 lbs. propane tank (4.7 gallons).
- Unlike many other sites, we actually tried to find out information about each of the above requirements. However, we are human and are therefore capable of the odd oversight or mistake. Please let us know if you spot any missing or erroneous values so that we can fix them.
