The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, and the extra features it benefits from.

Power & Run Time

The Firman T04073

The Firman T04073 delivers 120/240V and benefits from a tri-fuel technology that allows it to run on gasoline, propane, or natural gas. When gasoline-powered, it enjoys a running wattage of 4,000W and a peak wattage of 5,000W. When propane-powered, it benefits from 3,600 rated watts and 4,500 peak watts. Its natural gas operation offers 3,200W of rated wattage and 4,000W of starting wattage.

Enjoying a noise rating of 67 dBA (less noisy than background music), this generator can be started thanks to a classic hand-operated recoil starting mechanism, but also to a practical and straightforward electric starter (battery included).

Concerning its running time, the T04073, featuring a 5 gallons fuel tank, can continuously run for around 14 hours at 50% load with a full gasoline tank (consuming fuel at approximately 0.36 gallons per hour). Alternatively, when utilizing propane, it offers around 9 hours (on a 20 lbs tank - propane consumption around 0.52 GPH) of runtime.

The powering of sensitive electronic devices with the T04073 is not recommended due to its relatively high THD (<14%).

Outlets

The control panel includes the following 4 AC outlets:

Though it may not be labeled as 'RV Ready,' this Firman generator offers the benefit of hassle-free RV connectivity through its L5-30R receptacle, allowing you to easily power your RV with the assistance of an L5-30P to TT-30R adaptor (included). Besides, as it features a twist-lock L14-30R receptacle, the T04073 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

Measuring L29.8 x W27.5 x H26.1 in, the classic open frame build of the Firman T04073 delivers stability and easy maintenance access to components, facilitating air circulation. This type of design is ideal for tough environments and heavy outdoor use.

As the generator's weight is 123.4 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nonetheless, the limited maneuverability is compensated for by utilizing its wheel kit (⌀8") and its folding handle, which facilitates shifting once the generator is set on the ground.

Features

The T04073's control panel

The control panel of the T04073 is equipped with a convenient meter, providing voltage, frequency, and lifetime hours data, aiding in monitoring its status and activity.

In addition to this info, the device’s light indicator will display if the generator is ready.

The inclusion of a built-in fuel gauge in the generator streamlines gas level checks for quick and convenient assessments.

In terms of security, the generator features an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during its use.

The T04073 also benefits from Firman’s CO Alert carbon monoxide shutdown, which automatically shuts down the engine when harmful levels of carbon monoxide accumulate around the generator or a CO Alert fault occurs.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman T04073 also is packed along with the following accessories: funnel, cover, propane hose, oil, tool kit and RV adapter.
