Power station runtime for CPAP machines
Estimated hours at the ResMed AirSense 11 manual's typical (56.1 W) and peak (73.2 W) power consumption, and at an 80 W ceiling (DreamStation 2 power supply needed for humidification). Battery math only.
| Station | AirSense 11 typical | AirSense 11 peak | 80 W ceiling |
|---|---|---|---|
| Jackery Explorer 2000 v2 | 30.9 h | 23.7 h | 21.7 h |
| BLUETTI AC180 | 17.5 h | 13.4 h | 12.2 h |
| Jackery Explorer 1000 v2 | 16.2 h | 12.4 h | 11.4 h |
| EcoFlow DELTA 3 | 15.5 h | 11.9 h | 10.9 h |
| BLUETTI AC70 | 11.6 h | 8.9 h | 8.2 h |
| Jackery Explorer 300 Plus | 4.4 h | 3.3 h | 3.1 h |
| EcoFlow RIVER 3 Plus | 4.3 h | 3.3 h | 3.0 h |
Where the CPAP figures come from
- ResMed AirSense 11: Typical 56.1 W / peak 73.2 W (manual's 65 W power supply specs; the manual does not split by humidifier on/off) Manual (PDF)
- ResMed AirSense 10 (with humidifier): Typical 53 W / peak 104 W (manual's 90 W power supply specs for the device with humidifier; no humidifier-off figure given) Manual (PDF)
- Philips DreamStation 2: No wattage published. The manual says an 80 W power supply is required to support humidification and that battery/DC operation does not support humidification. We use 80 W only as a worst-case ceiling with humidifier. Manual (PDF)
Power-supply ratings describe the maximum the adapter is designed for; actual draw depends on pressure, humidifier and heated-tube settings, and room conditions. None of these manuals publishes separate with- and without-humidifier wattages, so we cannot show that split. Running a CPAP from its DC cord/adapter instead of the AC outlet avoids inverter losses; this site's figures assume AC.
