The generator FIRMAN H07552 has a 9400-watt and 7500-watt output (8450/6750 LPG). Our Max Pro Series 439cc FIRMAN engine produces power which runs relaxed and economical owing to the Phoenix Fat Head Block.
Thanks to our Whisper Series muffler and USDA Forest Service-approved spark arrestor, it is quieter and more efficient. With an industry-leading fuel capacity of 8 gallons, this generator can run for an incredible 12 hours. Pressing a button on the H07552 gets you up and running.
How much power can we get, and How much time can this Generator run?
The Firman H07552 can run on 120/240V and provides power and adaptability thanks to its dual-fuel technology. Power output is 7,500 W at idle, rising to 9,400 W at full throttle. It has a rated power of 6,750 watts and a peak power of 8,450 watts when powered by propane.
The generator can produce 74 decibels of noise (only slightly louder than a dishwasher). The starting mechanisms include a standard pull-start device and a sleek and straightforward electronic starter (battery had).
Fuel capacity of 8 gallons, the H07552 can run for roughly 12 hours at 50% gasoline load and around 5 hours with a 20 pounds propane tank (fuel consumption approximately 0.94 GPH).
Number of Outlets
In the control panel, you’ll see the following five ports:
- GFCI for 120V, 20A (5-20R)
- A 30A 120V Power Strip (L5-30R)
- 120/240V 30A surge protector (L14-30R)
- A 50A power strip for 120/240V. (14-50R)
This Firman generator includes an L5-30R connector, making it easy to connect to an RV with an L5-30P to TT-30R converter. But it isn’t nearly ready for virtual reality. And because the H07552 has an L14-30R rotary lock socket, it is breaker ready – you can quickly connect it to your circuit breaker to power your home during a power outage.
Portability of the Generator
The standard open-frame design of the Firman H07552 provides stability and allows the generator to be lifted above ground level, measuring L30.2 x W27.5 x H26.3 in. The design is excellent for use in extreme weather conditions and outdoor situations.
Even though the generator is technically portable, lifting or transporting it by hand would be difficult due to its 212-pound weight (mobile). However, the generator can be readily moved once it is placed on the ground thanks to a set of wheels (about 10″) and a folding handle (a clever solution to the generator’s inability to be shifted).
Features we like about this machine.
The H07552 and the control panel have a meter showing voltage, frequency, and life. Use this function to maintain tabs on your current location and activities at a glance.
The fuel gauge on the generator makes it simple to check the generator’s fuel level.
Automatic low oil shutdown and overload protection (circuit breaker) ensure your safety while using the generator. The generator.
The Firman H07552 comes with essential documentation and an owner’s manual (opens in a new tab) to assist you in rapidly starting the generator and a tool kit, funnel, oil, cover, and propane line.
Warranty information
A three-year warranty covers the Firman H07552. This warranty may be limited and not apply to all generator components.

Firman H07552 comparison with other
To give you an idea of how the Firman H07552 compares to other generators of the same power, the following are provided (between 7000 and 8000W)
- For a generator capable of producing between 7,000 and 8,000 nominal watts, the Firman H07552 fits in the typical weight range. Briggs & Stratton 30430A is a champion in power above range with a dry weight of just 190 pounds if you’re concerned about weight.
- This generator’s 74 dBA noise level is within the expected range for this type of power. For those concerned about noise pollution, the Westinghouse WGen7500 is one of the quietest generators, with a noise level of 72 dB.
- The H07552 has one of the best run times among its similarly strong competitors. The Predator 9000, which has equivalent power, has a runtime of around 12 hours for autonomy.
At the right price, hard to beat. Like several others, I purchased this generator at Costco, for less than half the cost of what Amazon is quoting.
We live on a small farm, and this generator’s job was to primarily run the pump house (multiple pumps, but the largest one is 3.5hp) , and provide some aux power to the house and garage to keep the fridge and deep freeze running.
