I was able to purchase a 12 vdc adapter cord for my CPAP machine. That way I don't have to use an inverter if I don't have 120 vac available. This is probably a better option because of the inherent power loss in an inverter. The adapter cord is long enough to reach the living room 12 vdc outlet from our bedroom. We don't dry camp so this is only for emergencies when 120 vac is not available.
