In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.
Power & Run Time
The Firman H05751
Featuring dual-fuel technology, the Firman H05751 provides 120/240V, and offers both power and versatility. Running on gasoline, it delivers a running wattage of 5,700W and a starting wattage of 7,125W. When propane-powered, it offers 5,700 running watts and 7,125 starting watts.
With a noise rating of 74 dBA (just slightly more noisy than a dishwasher), the generator features a classic hand-operated recoil starting mechanism, but also a convenient and easy-to-use electric starter (battery included).
The running time of the H05751, 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 H05751 has a high THD (<25%), it is not recommended to use it to power sensitive electronic devices.
Outlets
The control panel features the upcoming 6 AC outlets:
Despite not meeting the 'RV Ready' criteria, this Firman generator grants the advantage of simple RV compatibility via its L5-30R receptacle, enabling you to conveniently power your RV by using an L5-30P to TT-30R adaptor. Besides, since it boasts a twist-lock L14-30R receptacle, the H05751 is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.
Portability
With dimensions of L30.2 x W27.5 x H26.3 in, the standard open frame design of the Firman H05751 provides stability and easy maintenance access to components, as well as good air circulation. The device has been designed for tough environments and demanding outdoor use.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 194.5 lbs. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.
Features
The H05751's control panel
The control panel of the H05751 includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.
Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Firman H05751 ships with supplementary accessories: tool kit, oil, propane hose and funnel.

The Firman H05751 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman H05751 compare to dual fuel generators of similar power (between 5500 and 6500 W).
- At 194.5 lbs, the Firman H05751 stands out as one of the heavier dual fuel generators rated from 5500 to 6500 watts. If you are mindful of weight, the Pulsar PGDA70BiSCO is among the top contenders in this power range, with a dry weight of 118 pounds.
- When compared to other units producing a similar running wattage, this generator and its lowest emitted noise of 74 dBA stand out for being on the louder side. For those who are looking for a less noisy device, we suggest the Pulsar PGDA70BiSCO. With just 62 dBA, it is one of the most quiet devices in this power range.
- As the H05751 features an autonomy of around 12 hours at 50% load, it has one of the highest run times in comparison to the other dual fuel generators of its power range.
- While the run time is an important parameter, it is dependent on the fuel tank's capacity and thus, doesn't say much on its own unless we consider fuel consumption as well. In fact, this generator is not one of the most fuel-efficient options in the aforementioned wattage range: its estimated gasoline consumption at 50% load is around 0.67 GPH. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.38 GPH, the DuroMax XP7000iH is a device you could look out for.
The bottom line
- Dual Fuel
- Several accessories included
- GFCI Outlets
- Electric start
- High run time
- No remote start
- On the heavy side (194.5 lbs)
- On the noisy side (74 dBA)
- Low fuel efficiency
