Can I use the cigarette lighter adapters in vehicles to power my CPAP machine?

Yes, but here are a few helpful hints:

  • Make sure the cigarette lighter socket works.

  • In a motorhome, check if the outlet is connected to a separate battery or if it uses the coach or engine battery; use of your CPAP machine may drain your engine battery and prevent you from starting the motor if the outlet connects to the engine battery.

  • Review and understand how to operate your inverter.

  • Check your CPAP machine's operations manual to find out if your humidifier will work on 12 volt power.
