The Medistrom Pilot-24 Lite is a compact lithium-ion battery backup for 24V CPAP and BiPAP machines. It powers your therapy during outages and on the go, for travel, camping, or flights. It is compatible with the ResMed AirSense 11, AirSense 10, and AirMini, and runs for 1 to 2 nights at an average pressure with the humidifier and heated tubing turned off. If the power goes out overnight, your machine draws from the Pilot-24 Lite without any interruption to your therapy, so it works as a true backup (an uninterruptible power supply). It also doubles as a travel power bank, with about 19,000 mAh to charge a phone or tablet through the built-in USB port. Stay powered overnight, even when an outlet is not an option. What is included: Pilot-24 Lite battery Battery carrying sleeve DC output cable for the AirSense 10 DC output cable for the AirMini Short charging adapter cable for the AirMini Other 24V machines, such as the AirSense 11 and ResMed S9, connect with a cable kit sold separately.
