Running CPAP Without Utilities
How do you operate your CPAP machine when not hooked up to power? Please be specific if you have found a way that works; particlarly when boondocking for several days Thanks.

As mentioned some CPAP machines are 12 volt and are much more efficient than those that require an inverter and 120 volts. There is also a big variation in power consumption for the humidifer module. Typically the humidifer will consume as much or more than the blower. Some CPAPs even come with heated tubing. I cannot imagine how much power that would take.
Getting accurate data on your specific unit can be difficult. Typically the Respironics manuals show maximum power needs. An efficient 12 v unit can use as little as 25 AH/night, maybe 50 with the humidify on a relatively low setting. Plan on draining a typical car sized battery to 50% or less every night or at most every 2 nights.
