I used my CPAP for six days of tent camping at Oshkosh. The battery was a 9.6Ah LiFePO4. I recharged it each day from a solar panel, and it typically took 3Ah each time. The CPAP was one not requiring a conventional water humidifier as I described in my earlier post. But the weather was so humid that I might have gotten by with my standard CPAP and no humidifier.
