In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Firman H05751

The dual-fuel technology of the Firman H05751 allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 5700W and a starting wattage of 7125W. If propane-powered, it gives 5700 rated watts and 7125 starting 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 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).

Since the H05751 has a somewhat high THD (<25%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel features the following 6 AC outlets:

While this Firman generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, as it features a twist-lock L14-30R receptacle, the H05751 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 design of the Firman H05751 is a typical, open frame, with the dimensions of L30.2 x W27.5 x H26.3 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy 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. 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 H05751's control panel

To help you monitor the H05751's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman H05751 also comes with several accessories, including: oil, funnel, propane hose and tool kit.

Emissions

The Firman H05751 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
