Unboxing Experience:

Like all Champion machines, this generator comes in pretty decent protective packaging. I didn’t get any cracks or bends on the frame of my unit. During the unboxing, I got engine oil, a funnel, a wheel kit with a foldable handle, a propane (LPG) hose, and some user manuals.

Initial Setup of the Champion 7500-Watt Generator:

The initial setup of this unit was pretty easy; I did it within 15 minutes. You just need to attach the wheel kit, foldaway handle, stand, and battery plug. Also, you have to pour the engine oil and gasoline and attach the propane hose properly.

Design And Build Quality:

The design of this unit is pretty ordinary; you will not find any futuristic design like the Champion 4500 or 2000 watts generator.

Also, this unit is not that compact and lightweight; it has more than 200 lbs. of weight that can be managed to transport with the help of wheels and a foldable handle; however, without it, you can even lift for about 1 minute unless you are a weight lifter.

When it comes to the built quality this machine has a metallic frame with cast iron sleeves for added protection.

Outlets And Essentials:

  • 1x 120/240V 30A Locking (L14-30R) outlet.
  • 1x 120V 30A Locking (L5-30R) outlet
  • 4x GFCI 120V 20A Duplex (5-20R).
  • Circuit breakers.
  • Engine ON/OFF.
  • Ground.
  • Battery ON/OFF.
  • Intelligauge (frequency, Voltage, runtime).
  • Fuel selector.

Fuel Tank Size, Fuel Options, and Runtime:

Since this machine is dual fuel we have done tests on both Gasoline and propane.

Gasoline Test: As per the manufacturer’s statement, the unit has a 6.0-gallon gasoline tank that can run for about 8 hours on a 50% load, but it only lasts for about 7–7.5 hours in my case with the same load. With a 25% load, I managed to get 14–15 hours, which is amazing.

Propane Test: As per the manufacturer’s statement, 20 pounds of LPG tank can provide about 5.5 hours of run on 50% load; however, in my case, I got 4.5–5 hours with the same load. I have purchased a huge (100lb.) propane tank to avoid uninterrupted running.

Runtime Rating: 8/10 on gasoline, 6/10 on LPG; it can be improved easily.

What Can Champion 7500-Watt Generator Run (Load Test)?

This beast comes with a 439cc Champions 4-stroke engine that can produce 9375 surges and 7500 running watts on gasoline; however, on LPG, I got 8400 starting and 6750 running watts. Also, this machine has a built-in volt guard™ surge protector and cold start technology to avoid overloading and a longer startup time.

Well, we have operated the below appliances smoothly.

How Loud Is the Champion 7500-Watt Generator (Noise Level Test)?

Since this machine has a 439-cc, powerful engine that can produce decent power, you can’t expect too much silent operation.

The manufacturer has stated that it can produce 73 dB from 23 feet away, which is not true at all. You have to place it at least 100 feet away from your home or RV to get silent operation; however, on the worksite, you don’t have to put it 100 feet away because we always wear earplugs to avoid noise pollution.

Warranty and Maintenance:

Champion 7500-Watt Generator comes with 3 years of limited warranty and lifetime support from Champion. Champion also has lots of service centers around the globe, so you can easily replace your faulty unit with a newer one.

Also, the maintenance process is pretty easy; you just need to follow this guide to do maintenance safely.

Other than that, it is certified by the EPA (Environmental Protection Agency) and CARB (California Air Resources Board). You can operate it fearlessly; it will never harm you, your appliance, or your environment.
