Answer
Can the DuroMax XP13000EH run ResMed AirSense 11, typical power from the user guide?
Runs, surge risk
Runs. Running draw 56 W fits within 10,500 running watts, and published startup 73 W fits within 13,000 starting watts. This is an open-frame generator; for sensitive electronics or medical devices an inverter generator (under 3% THD) is the safer choice.

What watts were compared?
Generator: 10,500 running W and 13,000 starting W on gasoline. Appliance: 56 W running, 73 W startup.
How long will it run?
Fuel runtime depends on total load. Published runtime: 8.5 hr at 50% load on gasoline, 6.5 hr at 50% on propane.
Where did the numbers come from?
DuroMax spec sheet: gasoline 13000 starting / 10500 running; propane 12350 / 9975; 120/240V 30A twist-lock and 14-50R; 8.5 hr gas / 6.5 hr propane at 50%. Americas user guide, 65 W power supply section: typical power consumption 56.1 W (111.5 VA) and peak power consumption 73.2 W (137.6 VA). This is the published system figure, not the lower no-humidifier row on ResMed's separate therapy-power sheet.
Safety first
- Run a generator outdoors only, at least 20 feet from the house, with the exhaust pointed away from doors, windows and vents. Never in a garage, basement, shed or crawlspace, even with the door open.
- Carbon monoxide is odorless and can kill in minutes. Keep battery CO alarms working inside the home.
- Never backfeed a house by plugging a generator into a wall outlet or dryer receptacle. It can energize utility lines and kill a lineworker or a neighbor.
- Connecting to home wiring requires a transfer switch or a listed breaker interlock with a power inlet box, installed by a licensed electrician and permitted where your jurisdiction requires it.
