CPAP Machine Powers

Most CPAP, APAP and BiLevel machines today are designed to operate on both AC and DC voltage. In the United States, the AC current from a wall outlet is 110 volts. Overseas, the AC current is usually 220 or 240 volt. Most batteries produce 12 volt DC current.

Battery backups in CPAP therapy are used to travel or to run your machine in case of power outages. There are two main options for batteries: integrated battery backs and stand alone batteries. Integrated battery packs attached to your machine, power it for more than 8 hours and travel very well. Stand alone battery packs vary in size depending on the life of the battery. Many are travel friendly. Some machines require unique or custom power configurations.
