The manufacturers claim up to six days backup for a CPAP machine. While this is a little optimistic, it is possible. Of course for the best battery times, the quoted stats are with the dehumidifier and heating switched off. They’ve also set the CPAP to fixed low pressure. These are power saving methods that provide the best battery backup times.

Under these conditions, they have achieved amazing results as listed below for various compatible CPAP models:

Resmed S9: 40 – 50 hours (5 – 6 nights)
