A:Answer Hello there,
Please check on the power requirements of your Phillips cpap machine. This works with most round-pin connectors. A device is compatible if the 1) correct tip is available, 2) voltage is between 3 and 12 V DC, 3) input does not require more than 1.3 A of current, and 4) polarity is positive. Not for use with laptops.
