• The thinnest, lightest, most powerful battery for CPAP machines on the market today..
• With the addition of a power inverter or auto charge DC cable you can safely and efficiently recharge your Battery Pack via the lighter/power socket of a vehicle giving you even more time to enjoy your outdoor adventures..
• Use in a single battery configuration or pigtail two batteries together for even more power..
• Works with most makes and models of CPAP, BiLevel and other PAP devices. The DC capability, voltage requirements and plug polarity of the device will determine how it connects to the Battery Pack; therefore, the use of a power converter or power inverter may be required. See our FAQ Flyer for additional information on when a power converter or power inverter is required in conjunction with the Battery Pack..
• Use the Battery Pack on land, at sea or in the air. Great for powering your CPAP machine during outdoor adventures, on boats/cruise ships and long airline flights (meets requirements for lithium-ion ion batteries allowed in carry-on baggage)..

The Freedom CPAP Battery gives you the freedom to power your PAP device when and where you need it - no matter where your world takes you! Travel: The perfect solution for remaining compliant with your PAP therapy when enjoying your favorite outdoor activities, taking adventures on the road, or riding the high seas. Meets FAA requirements for lithium-ion batteries taken in carry-on baggage during air travel. Power Outages: Never worry about less nights without your PAP therapy during power outages. Simply plug the Freedom CPAP Battery into the wall outlet and connect your PAP device to the battery. When AC power is available it will bypass the battery cells to power your device but during an outage the battery will recognize the loss of AC power and automatically begin powering your PAP device. Other Devices: As an added bonus the USB port and/or included DC input cord let you use the Freedom CPAP Battery to charge other small electronic devices such as cell phones and s. Compatibility Respironics System One, Respironics M Series, and Devilbiss IntelliPAP series. Some older obsolete PAP devices and targeted ventilation PAP devices may not be compatible with the Freedom CPAP Battery. Estimated Run Times The Freedom CPAP Battery will power a Respironics System One, Respironics M Series or Devilbiss IntelliPAP series device for 1-2 nights before needing to be charged. Run times are estimates and depend upon several factors including PAP device type and pressure setting. Run times are based on CPAP devices without the use of heated humidification or heated tubing on a pressure setting of 10 cm/H2O. The use of heated humidification and heated tubing will reduce run times by two-thirds in most cases. Need longer run times? Kit includes a DC power pigtail cord that allows two batteries to be pigtailed together to increase run times. The next generation of the C-100 model.
