Devices and assumptions
| Device | Qty | Hours a day | Running | Starting | Source |
|---|---|---|---|---|---|
| ResMed AirSense 11 CPAP (manual typical draw) | 1 | 8 | 56.1 W | No extra | ResMed user guide |
Together: 56 W running, about 56 W while the largest motor starts, and 449 Wh a day. Over the 72-hour goal that is 1,346 Wh at the outlet calculated.
- CPAP draw is ResMed's typical figure from the AirSense 11 user guide, which does not say whether heated humidification was on.
- Eight hours of use per night; nothing else is plugged in.

What would change this answer
- Your own device watts: the label on the device beats any typical figure. Enter it in the calculator.
- Inverter idle draw: most makers don't publish it, so hours here leave it out. Small loads feel this most.
- Cold: below a maker's temperature range a station may stop discharging or charging.
Our take
CPAP draw depends heavily on the heated humidifier and heated tube. ResMed's guide gives a typical and a peak figure without stating the settings, so treat this as a planning number and confirm your own machine's draw with its manual. Running the CPAP from a DC adapter, where your maker sells one, avoids inverter loss.
