The verdict

Why it scored a 85

At $715, the Champion 201050 is a 4,000-watt dual-fuel inverter built for RVs, with a TT-30R outlet, 25 hours on a propane tank, and enough output for a 13,500 BTU air conditioner. Warranty leads at 100 on 3-year coverage and lifetime tech support, with Satisfaction at 90, Reliability at 88, and Features at 82. Quality sits at 76 for the open-frame design, and Value at 82 for the price. The caveat: this listing ships from a third-party seller, so check the seller before buying; Champion-sold listings exist. It is for RV owners who want dual fuel and inverter-clean power.
