Side by side
Champion 201176 vs GENMAX GM9000iEDC: Champion supports natural gas, and GENMAX gives more gasoline running power
Quick verdict
Natural gas is the reason to pick Champion. GENMAX is the one to get for higher gasoline running output, remote start and a quieter published sound figure.
Before you buy
Why, and what it costs you
Where these two really part ways
Champion 9000-Watt Tri-Fuel Inverter with CO Shield is the better match for “Power a refrigerator and the essential lights” and “Run it on my home natural-gas supply”. GENMAX GM9000iEDC Dual Fuel Inverter Generator is the better match for “Cut down on campsite noise” and “Fire it up from indoors before heading out”.
Where this comes from
This lines up the current strong and useful fit ratings for the exact products. It does not roll them into one overall score.
The catch

How we worked this out
This lines up the current strong and useful fit ratings for the exact products. It does not roll them into one overall score.
These needs do not split the pair
Both meet the same 2 of the 2 needs this comparison is built around, so the choice comes down to “running and starting output” and “fuel and voltage”.
How we worked this out
Both products are checked against the same needs. The first verified differences still standing are named here.
Models that handle “Get a 240V well pump going” and “Power a window air conditioner”
12 of the 24 generator sets checked handle both “Get a 240V well pump going” and “Power a window air conditioner”. Both make the cut.
How we worked this out
You can reproduce the count by filtering the current category for models with a strong or useful fit on both needs.
Plug in your numbers
Can either generator run what you need?
This checks hard limits only. Personal preferences are left out of the math.
Champion 9000-Watt Tri-Fuel Inverter with CO Shield
Works with your numbersOn gasoline, it is rated for 7,250 running and 9,000 starting watts. With reserve, your load plan calls for 1,200 watts running and 2,900 watts starting.
GENMAX GM9000iEDC Dual Fuel Inverter Generator
Works with your numbersOn gasoline, it is rated for 7,600 running and 9,000 starting watts. With reserve, your load plan calls for 1,200 watts running and 2,900 watts starting.
The estimate adds up the running watts of everything on at once, the biggest single startup surge and 15% headroom. Check each appliance label before you rely on it. Never run a fuel-burning generator indoors, in a garage or near doors, windows or vents.

Spec by spec
Where they really differ
| Spec | Champion 9000-Watt Tri-Fuel Inverter with CO Shield | GENMAX GM9000iEDC Dual Fuel Inverter Generator | In practice |
|---|---|---|---|
| Running and starting output | 7,250 running W. 9,000 starting W on gasoline | 7,600 running W. 9,000 starting W on gasoline | Higher published output is useful only if your room, surface or workload calls for the extra headroom. It does not, by itself, prove better results. |
| Fuel and voltage | gasoline, propane, natural gas. 120/240V output | gasoline, propane. 120/240V output | It can act as a strict compatibility test against your power supply, connection and planned load. |
| Power quality and handling | Inverter generator. Clean-power requirement met | Inverter generator. Clean-power requirement met | Both models show the same result for “Power quality and handling”, so this row won't decide between them. |
Trade-offs
What each pick costs you
