The [Champion 9000 Electric Start Tri-Fuel Inverter Generator]() is in a different category. It’s designed for homeowners who want inverter-quality power with the ability to run on gasoline, propane, or natural gas (with a plumber-installed connection). I tested the Champion 9000 at home using power tools outdoors, running an extension cord into my workshop, and powering multiple household appliances at the same time. Ahead, find out what happened, what I liked best, and what you should be aware of before buying. ## Is the tri-fuel system practical for home backup power? Yes, and its multi-fuel capability is one of the top features of this generator. Tri-fuel capability gives you real flexibility depending on what’s available during an outage. I tested the Champion on gasoline and propane, and it ran very well on both. Gasoline offers the strongest output, but propane is easier to store long-term and can be a smart backup fuel when gas stations are unavailable. I didn’t test it on natural gas because I don’t have a natural gas line to my home. But the ability to connect to a home gas line is a major advantage for buyers who want a generator that can be ready to run without relying on stored fuel alone. Be aware that in most communities, a licensed plumber is required to connect a generator to a natural gas line. ## Noise Level, Portability, and Setup Considerations This is an open-frame inverter generator, and it’s louder than enclosed inverter models. Champion rates it at 72 decibels. I found the noise tolerable, but buyers expecting “whisper-quiet” inverter operation should know this won’t match the low noise level of smaller closed-frame units. At 165.8 pounds, the [Champion 9000]() is heavy, but not as heavy as some higher-output generators I’ve tested. Still, it’s not something most people will want to move often, so plan ahead for storage and positioning. I also liked that it offers both electric start and recoil start. The electric start worked flawlessly in my testing, but it’s reassuring to have recoil as a backup. One important setup note: this generator ships with shipping bolts that must be removed before starting. If you skip that step, there’s a risk of damaging the unit. Finally, the CO Shield adds an extra layer of safety for users concerned about exhaust exposure, especially when placing the generator outdoors near residential structures or occupied areas. - ![12V car-type adapter close-up]() *Photo: Glenda Taylor for BobVila.com* - ![A person pulling Backup Recoil Start on the Champion 9000S]() *Photo: Glenda Taylor for BobVila.com* - ![Champion 9000S shield]() *Photo: Glenda Taylor for BobVila.com* - ![Champion Fuel Selector close-up]() *Photo: Glenda Taylor for BobVila.com* - ![Champion Tri-Fuel Inverter Generator close-up]() *Photo: Glenda Taylor for BobVila.com* - ![Champion CO Shield]() *Photo: Glenda Taylor for BobVila.com* - ![Easy-access filters]() *Photo: Glenda Taylor for BobVila.com* - ![Filling tank of Champion Tri-Fuel Generator]() *Photo: Glenda Taylor for BobVila.com* - ![Remove shipping bolts before starting the engine]() *Photo: Glenda Taylor for BobVila.com* - ![Outlets on the Champion 9000S close up]() *Photo: Glenda Taylor for BobVila.com* [][][] ## Who is the Champion 9000 best for---and who should skip it? The [Champion 9000 Tri-Fuel Inverter Generator]() is best for homeowners who want high-output inverter power with fuel flexibility for emergencies. Based on my testing, it’s a strong choice for running major appliances and powering tools when you need reliable performance without constant load babysitting. If you want a lightweight, [ultra-quiet inverter generator](), this isn’t the right fit. But if you want a capable tri-fuel inverter that can handle real household loads, the Champion 9000 delivers. ## Author Glenda Taylor is a BobVila.com staff writer with a background in the residential remodeling, home building, and home improvement industries.
