The Auto Charge DC Cable allows you to safely and efficiently charge the Freedom V2 CPAP Battery via the cigarette lighter/power socket of a vehicle giving you even more time to enjoy your outdoor adventures! This gives you the ability to stay on the go. It will completely charge the Freedom battery from completely empty to 100% in 3-4 hours.

NOTES:The vehicle must be running during the charging process to ensure the battery receives proper voltage to successfully charge and to prevent draining the vehicle’s battery.We do not recommend the use of any other brand of "universal" auto charge cable as it may damage the Freedom CPAP Battery or discontinued C-100 model CPAP Battery.
