There are plenty of CPAP users on the road. I'm selling a near new Lithium battery I used for a ResMed 10 CPAP including a 12v charger. Also included is a 12v adapter to plug the CPAP directly into a 12v source. Battery works great and powers the CPAP 2-3 nights if the heater is turned off. I've switched to a different device and don't use a CPAP any longer. I paid $400, selling $125 US. PM or give me a call at 805 691-9357.
Some who wander are not lost...
