*Planning ranges assume humidification and heated tubing are off. Actual runtime varies by CPAP model, pressure, mask leakage, temperature and battery condition.

Will it work with your CPAP?

Check your model, cable and voltage.

01Match the exact CPAP model

Model families can use different power requirements. Use the full name printed on the machine and its original adapter.

02Confirm 12V, 16V, 19V or 24V

EASYLONGER batteries support these selectable DC outputs. Select the voltage required by the CPAP—not a guess based on connector shape.

03Plan with real comfort settings

Humidification and heated tubing can substantially increase power demand. Test one full night before depending on backup.

04Know what PRO adds

PRO models add voltage memory and a more precise battery display for repeat setups and clearer reserve monitoring.
