Provides 4× CEE 7/3 (230V), 1× Commando (16A/32A) (120/240V 60Hz).
Inverter alternator with ≤12% THD. Safe for microprocessor-controlled appliances.
Inductive motor/compressor load with 1.9× starting surge (motor inrush) (98.9% worst-case surge margin).
Never operate indoors or in attached garages due to lethal carbon monoxide (CO) exhaust.
Safe envelope verified: Starting surge (140W) remains comfortably below the 13000W surge trip line, with steady-state operation settling into the safe continuous zone at 75W.
About 21.2 hours on a full 8.3-gallon tank of gas, with the box fan averaging 75 W: 1% of the DuroMax XP13000EH's 10,500 W rating. At this light load below the lowest tested point (50% load), fuel consumption interpolates between DuroMax's lowest published test load and Eco-Throttle idle fuel consumption. That's about 2.7 days per tank. On propane (40 lb cylinder): about 16.2 hours.
Yes. The box fan's start-up peak of about 140 W (up to 200 W) fits within the DuroMax XP13000EH's 13,000 W starting-watt rating, with 98% headroom even in the worst case.
Running a box fan uses about 0.39 gal per hour at this 1% load, or 3.1 gal per day of use. A full 8.3 gal tank lasts about 21.2 hours. On propane: about 2.5 lb per hour, so a 40 lb cylinder lasts about 16.2 hours.
