CPAP hours on the R1500
| Case | Watts | On the R1500 |
|---|---|---|
| AirSense 10 without humidifier (ResMed) | 7 W | 17.5 nights of 8 hours |
| AirSense 10 with humidifier (ResMed) | 22 W | 5.6 nights of 8 hours |
| AirSense 10 with humidifier and heated tube (ResMed) | 34 W | 3.6 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 207 Wh from the battery. At the R1500’s 650 W solar input and our 75% assumption, that takes about 0.4 hours of strong sun to put back; a full charge from empty takes about 2.4 hours. See solar recharge time.
Follow your doctor’s and the CPAP maker’s advice on backup power.
