How we calculate it

Runtime = capacity (Wh) × 0.85 ÷ 90 W

For 3 nights you need about 2,550 Wh (2,160 Wh of energy plus inverter losses). Running other devices at the same time? Add them in the runtime calculator.

Tips to run your CPAP with heated humidifier longer

  • The humidifier and heated tube are the biggest consumers; lowering the setting by 1–2 levels saves a lot.
  • Fill the chamber with room-temperature water so the heater works less.
  • Consider a DC power cord designed for your model for better efficiency.
