CPAP hours on the AC180
| Case | Watts | On the AC180 |
|---|---|---|
| AirSense 10 without humidifier (ResMed) | 7 W | 5.6 nights of 8 hours |
| AirSense 10 with humidifier (ResMed) | 22 W | 3.3 nights of 8 hours |
| AirSense 10 with humidifier and heated tube (ResMed) | 34 W | 2.5 nights of 8 hours |
Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it).
ResMed measured these for the AirSense 10; higher pressure or humidity draws more. A DC cord from the CPAP maker skips the inverter and lasts longer.
Keeping it going with solar
A night with an AirSense 10 with humidifier uses about 176 Wh, about 348 Wh from the battery with its own 15 W draw. At the AC180’s 500 W solar input and our 75% assumption, that takes about 0.9 hours of strong sun to put back; a full charge from empty takes about 3.1 hours. See solar recharge time.
Follow your doctor’s and the CPAP maker’s advice on backup power.
