Pros
- 9,000 running watts on gasoline (8,100W on propane) — enough for whole-home essential circuits
- Dual fuel lets you switch between gasoline and propane on the fly, useful when one fuel is scarce during an outage
- Transfer-switch ready with 50A/30A outlets for direct integration into a home panel
- Parallel capable and rated under 3% THD, safe for sensitive electronics despite the large output
Cons
- 189 lb dry weight — this is a wheeled, stationary-use generator, not something you load solo
- 64 dBA noise output is loud for extended residential use, especially at night
- Fewer independent long-term reviews than Honda/Champion at this wattage tier
