Zoom on the Firman H07552
In summary, the Firman H07552 is a portable generator especially useful for:
- Food van owners who know that just a short power outage could lose them hundreds of dollars
- Professionals who want to ensure that a power failure will not prevent them from working
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
The Firman H07552
Thanks to its dual-fuel technology, the Firman H07552 delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 7500W and a peak wattage of 9400W. When propane-powered, it has 6750 rated watts and 8450 peak watts.
With a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), the generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included).
The running time of the H07552, with its 8 gallons fuel capacity, can reach around 12 hours at 50% load on a full tank of gasoline (fuel consumption around 0.67 GPH). With propane, it can reach around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH).
As the H07552 has a relatively high THD (<25%), it is not recommended to use it to power sensitive electronic devices.
Outlets
The control panel includes the following 5 AC outlets:
Even though this Firman generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, as it features a twist-lock L14-30R receptacle, the H07552 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.
Portability
The Firman H07552 has a conventional, open frame design, of the following dimensions: L29.8 x W26.4 x H26.3 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 212 lbs make it incredibly difficult to manually lift and transport. Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
Features
The H07552's control panel
The control panel of the H07552 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman H07552 also is packed along with the following accessories: cover, tool kit, funnel, propane hose and oil.
Emissions
The Firman H07552 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor, so it is adequate for use in forested areas.
Product Video
The Firman H07552 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman H07552 compare to generators of similar power (between 7000 and 8000 W).
- As its weight is 212 pounds, the Firman H07552 falls in the expected weight range of the devices in the 7000-8000 rated wattage category. If weight matters to you, one of the champions in this power range is the Sportsman GEN85KIDF with only 133 pounds.
- As this generator can emit noise as low as 74 dBA, it finds itself in the average expected noise for this kind of 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 A-iPower SUA8000iSF, whose lowest noise levels reach just 65 dBA.
- Since the H07552 boasts with a run time of around 12 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the A-iPower SUA8000iSF, as it provides around 13 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator, with an estimated fuel consumption of just 0.67 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the A-iPower SUA8000iSF. With a fuel consumption of as little as 0.52 GPH, it is one of the most efficient generators currently on the market.
Price comparison
As you can see from this interactive chart, when compared to other 7000-8000W generators, the Firman H07552 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.

Of the 4 outlets is only one a GFCI outlet? So can a non-GFCI transfer switch be connected to the 120/240 V 30 amp outlet without tripping the generator breaker which happens with a GFCI outlet? (Asked July 10, 2019)
Correct. Only the 5-20R duplex is GFCI
Can it run on a homes in ground propane supply (Asked August 15, 2019)
Below-ground propane is no different than above-ground propane. So there's no reason why it wouldn't work.
I have two circuit boxes I would like to power and selectively/manually pick and chose from. Can I use the 50 amp and 30 amp plugs simultaneously to drive both boxes (one for each) with attention given to the max loads of the generator? (Asked November 06, 2019)
You can absolutely use these two outlets simultaneously.
Does it have a clean enough sine wave to recharge a Tesla in a emergency at 240V? (Asked November 25, 2019)
The THD stated by Firman for the H07552 is <25%. You'd have to contact Tesla to know whether that harmonic distortion is suitable to recharge your car. You can also refer to our article on charging a tesla.
Is the 50 amp plug wired for a RV? (Asked March 16, 2020)
The 50-amp outlet is a NEMA 14-50R. Wiring of 14-50R receptacles is four-wire (ground, neutral, hot, hot).
What would be the best transfer switch to use with this generator in order to provide power to my house? (Asked April 16, 2020)
We do not really like the term "best", as we think it's highly subjective. That said, the Reliance Controls 31406CRK (opens in a new tab) is one of the best-sellers on Amazon, and exactly fits the running wattage of the H07552.
If you use it to power a 50amp rv can you charge sensitive items in the camper electrical plug? Ie a cell phone or laptop (Asked July 12, 2020)
This unit has a THD <25%, which is too high to power equipment with sensitive electronics.

I AM STILL IN THE 5 HOURE BRAKE IN PERIOUD AND ALL IS PROCEDING WELL. MY ONLY COMPLAINT THUS FAR IS THAT THE UNIT IS NOISYER THAN EXPECTED. IT’S WORKIND AS DISCRIBED.
Works better than advertised
I’ve had this generator for 2 yrs started Everytime but leaked gas float was stuck quit leaking after it ran a few minutes changed oil be sure to watch how much oil you put in it says 37.2 oz but don’t over fill takes less than that easy gas gauge to read the wife fills it with gas when I’m at work when the power goes out she has no problem starting it also
Same mimimal quality as Eastern Tool,different label
