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
Travel CPAPs without heated humidification draw very little, so even the smallest stations cover a weekend. At loads this small, inverter idle draw can use more than the CPAP itself, and most makers don't publish it, so the hours shown are an upper bound.
