The Freedom CPAP Battery is compatible with most Philips Respironics CPAP machines. The unique and portable design makes it perfect for travel and even meets all current FAA requirements.
Freedom Battery Features:
Digital Display The digital display creates an easy-to-read charge level indicator which shows the current charge level and the percentage.
