The X9 is a universal CPAP and BiPAP backup battery designed to keep therapy running during power loss or when sleeping away from a wall outlet. It functions as an inline UPS: plug it into the wall, plug your machine into the battery, and the device automatically switches to battery power when an outage occurs. No setup, adapters, or extra cables require.
The system supports all CPAP and BiPAP models because it delivers standard AC power rather than machine-specific DC outputs. This makes it compatible with full-size devices, travel CPAPs, and non-CPAP electronics.
