Champion 201176 9000W Tri-Fuel Inverter

Champion's answer to the EU7000iS costs a third as much and adds propane capability: 7,000 running watts of closed-frame inverter power at a claimed 61 dBA from 23 feet, with both 50A and 30A 240V outlets ready for a transfer switch. Owners running whole-home essentials during outages report it handles well pumps, furnaces, and a smaller central AC, with quiet operation that genuinely surprises people used to open-frame roar. The CO Shield sensor and electric start round out a strong package. The complaint list from owner threads: at 214 pounds it's barely 'portable' despite never-flat wheels, the propane derate takes running power to about 6,300 watts, real-world noise climbs well above 61 dB under heavy load, and a few owners report early inverter-board failures — Champion support resolves them, but shipping a 200-lb unit for service is nobody's idea of fun.

The people's RV generator. Champion's 200988 pairs 4,500 starting watts with dual-fuel flexibility and electric start at well under half of Honda money, and the review volume — thousands across Amazon, Walmart, and Camping World — is overwhelmingly positive. Owners confirm it starts 13.5k BTU RV air conditioners, sips propane for up to 21 hours on a 20-lb tank, and holds clean sub-3% THD power for electronics. At 61 dB it's audibly louder than a Honda or the iGen4500, more of a steady hum than a whisper, and the 103-lb body rides on small, hard wheels that owners wish were bigger. Recurring gripes: the electric-start battery dies if you don't tend it (there's a maintenance charger port for a reason), propane output derates to 3,150 running watts, and oil changes require a slight tilt-and-funnel dance.

One of the best-selling generators ever made, and the archetype of the 'good enough for everything' budget dual fuel. Electric start, RV-ready TT-30R outlet, propane capability out of the box, and nearly a decade of owner history at around $550 — the review count across Amazon and Walmart is enormous and consistently positive. Owners run travel trailers, job sites, and essential-circuit extension-cord backup, and the 224cc engine has a reputation for starting after years of neglect (on propane especially, since there's no carb to gum). Known quirks from the threads: it's a 68 dB droner that campground quiet hours won't love, output on propane drops about 10%, there's no 240V so interlock users look elsewhere, the fuel selector and petcock feel plasticky, and cold-weather propane starts sometimes need a second try. Champion's phone support gets rare-for-the-industry praise.
