12V, 19V, 20V or 24V?
Your CPAP's power adapter label shows the voltage it needs. Set the battery to match. For 19V machines, use 19V on the ES270 and PRO models, and 20V on the ES400 AIR, ES720 and ES960. We've tested both. Earlier ES400 AIR units label the 20V setting 19V.
Prefer the car socket?
EAS10 and EAS11 plug into the 12V car socket on ES400 AIR, ES720 and ES960 models and give you 8.5 ft of reach. The ES270 has no car socket.
