What watts were compared?
Generator: 7,500 running W and 9,375 starting W on gasoline. Appliance: 56 W running, 73 W startup.
How long will it run?
Fuel runtime depends on total load. Published runtime: 10 hr at 1/2 load on gasoline, 5.5 hr at 1/2 load on a 20-lb propane tank.
Where did the numbers come from?
Champion operator's manual: gasoline 9375 starting / 7500 running; propane 8400 / 6750; L14-30R and L5-30R; 7.7 gal; 10 hr gas / 5.5 hr propane at 50% load. 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.
