DuroMax XP17500HX Generator vs DuroMax XP13500iH Generator

Buy the XP17500HX if your priority is raw power for whole-home backup: it delivers about 3,250 more running watts on gas and has two 50A outlets, so it can carry a larger transfer switch load. Buy the XP13500iH if you want cleaner, quieter power: its inverter produces under 3% THD and runs at 66 dB at quarter load, which suits sensitive electronics and RV or campsite use. The XP17500HX is the heavier, conventional-frame machine with a bigger 600cc engine; the XP13500iH is the more refined unit with an 8-gallon tank and roughly 10.8 hours at half load. Both share DuroMax's CO Alert shutdown, remote start, 100% copper windings and 5-year warranty, so the choice comes down to watts versus power quality.

• Choose the XP17500HX if you need maximum running watts for a large home, well pump, or big transfer switch load and can live with a conventional, louder generator.
• Choose the XP13500iH if you want inverter-grade clean power for electronics, RV hookups, or quieter neighborhood use and 10,500 running watts covers your needs.
