The XP15500HX is a dual-fuel portable generator rated at 12,000 running watts on gasoline and 11,500 on propane, with 15,500 and 14,500 peak watts respectively. It runs about 10.5 hours at half load on gasoline and roughly 15.8 hours at quarter load. The CO Alert system shuts the unit down when carbon monoxide builds up, a safety feature many portables in this class still lack. It suits whole-home backup and job sites that need 240V power, but it is heavy and loud compared with inverter generators.
