Design and Build Quality:

The Champion 4500-watt inverter generator is the prettiest machine I have ever seen in my life; it is a perfect blend of vibrant yellow and matte black.

The front of the generator has a decent foldable carrying handle, a control panel, and a small battery compartment below the control panel. The back contains a spark arrester and a bunch of vents as well.

On the right side, you will have a yellow removable panel that can be easily removed to do the necessary maintenance like cleaning the air filter, changing the spark plug, etc.; on the left side, you will have a pull starter and a small compartment to check out the engine oil and drain the overflowed fuel.

When it comes to portability, this guy has a wheel kit and a foldable handle with a compact size for transporting it like a briefcase.

Fuel Tank Size, Fuel Options, and Runtime Test:

The manufacturers have stated that at 25% load, this inverter generator can provide 14 hours of runtime with a single fuel tank of 2.3 gallons.

As per my experiment, I got 13 hours of run time on a 30% load, which is pretty decent. I must say the manufacturers are right about the fuel efficiency of this unit. Though this machine doesn’t have a dual-fuel option, you can still spend long winter nights comfortably.
