Buying Guide: Choosing Your Champion Generator

Fuel Type and Flexibility

Your first decision is between dual-fuel and tri-fuel capability. Dual-fuel generators, like the Champion models with remote start, run on gasoline and propane. This offers excellent versatility and often longer shelf life for stored propane.

Tri-fuel models add natural gas as a third option. This is a major advantage for whole-home backup, as you can connect directly to a residential natural gas line for virtually unlimited run time. Consider your primary use case and fuel availability when making this choice.

Power Output and Application

Match the generator’s wattage to your intended load. For powering essential home circuits during an outage, a unit with 10,000 running watts or more, like those in our guide to 9000-watt tri-fuel models, is often necessary. This can handle refrigerators, furnaces, and well pumps.

For recreational use, tailgating, or powering a few key appliances, a portable inverter generator in the 3500 to 6500-watt range is more suitable. These models are quieter, more fuel-efficient, and produce clean power safe for laptops and phones. Always calculate your total wattage needs before purchasing.

Start Method and Convenience Features

Electric start, activated by a push-button or rocker switch, is a significant quality-of-life feature. It eliminates the physical effort of a recoil starter. Some advanced models offer remote start via a key fob or even Bluetooth app control, providing ultimate convenience, especially in poor weather.

Also, look for user-friendly interfaces like Champion’s Intelligauge. This digital display monitors voltage, frequency, and run time, helping you track output and schedule maintenance. Safety features like CO Shield, which automatically shuts down the unit if carbon monoxide builds up, are critical for indoor air safety.

Portability and Noise Level

If you plan to move the generator frequently, check its weight and whether it has wheel kits and handles. Larger home standby units are heavier and less portable than compact inverter generators. Noise level, measured in decibels (dBA), is another key factor.

Inverter technology typically results in much quieter operation, often around 60-64 dBA. This is ideal for camping or neighborhoods with noise restrictions. Conventional generators are louder, which is an important consideration for both your comfort and your neighbors’. Explore more generator brands and technologies to see all your options.

Frequently Asked Questions

What is the advantage of a tri-fuel generator over a dual-fuel model?

The primary advantage is the addition of natural gas as a fuel source. If your home has a natural gas line, you can connect the generator for an essentially unlimited fuel supply during extended outages. This provides significant peace of mind and can be more cost-effective than storing large quantities of gasoline or propane.

Can I safely run a Champion tri-fuel generator indoors?

No, you should never run a portable generator indoors, including in garages, basements, or sheds, even with the door open. All combustion engines produce deadly carbon monoxide (CO) gas. Always operate the generator outdoors, at least 20 feet away from your home, with the exhaust pointed away from any openings like doors or windows. Models with CO Shield offer an extra layer of safety by automatically shutting down if dangerous CO levels are detected nearby.

How do I maintain my Champion generator for long-term reliability?

Regular maintenance is crucial. Always refer to your owner’s manual for a specific schedule. Key tasks include checking and changing the engine oil regularly, using fresh fuel with a stabilizer if storing for over 30 days, cleaning or replacing the air filter, and inspecting the spark plug. Running the generator for about 30 minutes every month under load helps keep the engine components lubricated and the battery charged if it has electric start.

What does “inverter generator” mean, and why is it important?

An inverter generator produces AC power, converts it to DC, and then inverts it back to a very stable, clean AC signal. This results in “clean” power with low total harmonic distortion (THD), typically under 3%. This is essential for safely powering modern sensitive electronics like smartphones, laptops, and flat-screen TVs without risk of damage. Inverter generators are also generally more fuel-efficient and quieter than conventional generators.
