Your CPAP Machine will run off the battery when the regular power source is not available in situations such as camping, road trips, and during air travel. Pilot-24 comes with additional features that are essential during power outages such as a bright LED light and a USB port which can be used for charging cell phones and other handheld devices. How long will it last? There are many variables that affect how long it will last. A few of them are: elevation, room temperature, inconsistent breathing, CPAP device pressure settings, how many times you got up that night, How many times you stopped breathing that night, and the different power levels required of various PAP devices. The battery runtimes will be different for each person. Using a low-med setting helps the battery last much longer. **USPS Express Shipping.
