How long does a charge last?

Depending on your CPAP machine settings and other accessories used, the average charge is between 8-16 hours.

The Pilot Lite batteries will last 8 hours minimum and up to 16 hours with pressures of 10cm or lower. Humidifiers, heated tubes, and mask leaks can all impact battery life. More demanding configurations such as a BiPAP or higher pressure settings can also result in lower run times. High altitudes will also deplete run time.
