Dual-Fuel Capability

Control Panel

The control panel of the Champion 4375 generator is a user-friendly touch panel that empowers users with intuitive and efficient management of the generator’s functions.

At the centre of the control panel, the Intelligence display stands out prominently. Adjacent to the Intelligauge, you’ll find the generator’s start feature, which provides easy and immediate control over the machine’s operation. Surrounding the switch are various outlets as well.

Furthermore, the volt guard as well as the low oil shutdown indicator is also located on the control panel. Moreover, the low oil shutdown indicator adds an additional layer of protection by automatically shutting down the generator when oil levels become critically low, preventing potential engine damage.

Overall, the control panel’s layout is designed with user convenience in mind. Essential controls are placed within easy reach and labelled clearly for straightforward identification. This ensures that even those who might not be well-versed in generator operation can navigate the panel with confidence.

Fuel Capacity and Runtime

The Champion 100307 dual-fuel generator features a practical fuel capacity. The gas tank can hold up to 3.4 gallons. It is universally agreed that generator experts do not recommend running a generator continuously for more than 8 hours, although larger tanks may extend the operational duration.

In operation, a fully fuelled gasoline tank yields approximately 9 hours of runtime at a 50% load. Conversely, using propane extends this runtime to about 10.5 hours with the same load.

Fuel Capacity and Runtime

To explain, if the generator is running on gasoline with a 1750-watt load, a complete tank will sustain it for 8 to 9 hours. Similarly, with a 20-pound propane tank, the generator can operate for 9 to 10 hours under a 1575-watt load.

However, it’s worth noting that the actual runtime might differ from the manufacturer’s estimates due to various factors. Variables such as the generator’s age, engine performance, appliance condition, wiring quality, and fuel quality can influence the runtime. As a result, a slight variance of 30 to 60 minutes from the stated runtime should be expected.

Power Output

The Champion 4375 generator boasts a utility power output, delivering 4375 peak watts (also called as surge wattage) and 3500 running watts when powered by gasoline. In the case of propane, the generator offers 3950 peak watts and 3150 running watts, showcasing its adaptability to different fuel sources. This power capacity positions the generator as an ideal solution for a diverse range of scenarios.


The generator is equipped with a reliable and efficient 224 CC 4-stroke Champion engine, engineered to provide consistent and stable power output while optimizing fuel consumption. With its 3600 RPM speed, whether you’re running propane or gasoline, you’ll never feel underpowered.
