Tested and Reviewed The Champion 4500 watt Inverter Generator

The Champion 4500-watt inverter generator is a perfect blend of versatility and convenience. Besides the dual fuel technology, this beast is equipped with the industry’s leading inverter technology to cope with the noise and unstable voltages.

I and my team have conducted multiple noise, runtime, load, frequency, and sturdiness tests to make sure whether the generator meets the expected standards or not.

Build Quality:

Though this machine doesn’t have a metallic casing, still the built quality looks pretty impressive with no construction issues. The copper windings, rubber mounts for motors, and cleaner wirings are cherry on top.


Champion 4500-watt is a perfect blend of sturdy plastic, premium copper, and edgeless design. it has a convenient foldaway handle to roam it around like a luggage bag.

The front holds a loaded control panel and small battery comportment beneath it, the back contains lots of vents and a spark arrestor to prevent flammable debris.

The right side has a removable to do necessary maintenance like oil change, filter cleaning, spark plug inspection, tune-up, etc. A smooth recoil start and a small comportment are added on the left for quick startup, instant oil or drain the gasoline.

Runtime Test:

With 25% load, this machine lasted for about 13 hours which is pretty decent, also at ½ load this machine managed to provide me 7-7.5 hours.

Besides impressive runtime on gasoline, this machine also has a dual fuel mechanism; you can integrate a hose and a 20-lb LPG tank to spend longer nights comfortably.

Load (Capacity Test):

Champion’s 4500-watt portable inverter generator is equipped with a powerful 212cc, 4-stroke OHV engine that can generate 4500 peak and 3500 running watts on gasoline. With LPG (Propane) this beast is providing 4500 starting and 3150 running watts.

Besides impressive power, this machine provides <3% THD (total harmonic distortions) to ensure your voltage-sensitive appliance will be free from sudden shocks.

Below are some of the appliances I have run to reach the actual limits of this portable inverter generator.

Noise Test of Champion 4500 Generator:

Like the Honda eu3000is and Westinghouse iGen 4500 watts, this machine also has a perfect enclosure and modern inverter technology to cope with the noise.

Well, I and my team have conducted the below noise tests with a Decibel meter.

  • At idle with eco mode “ON”, I got 56 – 57 dB (A) from 23 ft. away, however, on normal mode; I got 59 – 60 dB (A).
  • At 25% load, the generator was emitting around 62 – 64 dB (A) which is pretty fair for this type of machine.

NOTE: All the tests are conducted on a grossed surface; on a concrete surface you may go slightly higher decibels.

Ports, Outlet, Indicators and Sensors:

  • 120V, 30A AC Rv ready port.
  • Two 120V, 20A AC Outlets
  • 4 – mode Intelligauge with Power Meter (shows the runtime, voltages, frequencies,, etc)
  • Parallel Ports
  • Battery Switch
  • Ground 12V DC 8A Port
  • Circuit Breakers.
  • Fuel Level Indicator
  • Eco mode button
  • EZ starts dialing.

All ports and outlets are covered with weatherproof flaps; you don’t have to care about rain, snow, or bugs.

Parallel Support:

Besides the massive power, this machine also has parallel ports to combine two compatible machines. You just need to purchase a separate parallel kit and a compatible generator to double the power.

Wireless Remote Startup Test:

The remote control works perfectly from 70 – 80ft. However, from an increased distance, the generator may struggle to catch the signals

Maintenance and Usage:

The installation process is pretty straightforward; you need to remove the shipping support from the bottom, connect the battery plugs, press the choke button, and the generator is ready to fire up.

In addition to that, the machine has a clean wiring arrangement and visible 10mm bolts to do the maintenance task in an instant.
