This is the DC cord for DreamStation CPAPs by Respironics. It will not work with any other CPAP.
Can be used with the humidifier and heated tube, but these accessories will increase power draw and decrease battery life.
The 12V DC Battery Adapter is necessary if you need to connect your DreamStation Device to a Marine Battery.
Manuals & Guides
We do some boondock RV camping and this product works very well. We do not have a giant battery bank (2 Trojan T-105 6v) so I've not used the humidifier. My DreamStation device pulls just under 2amps based upon an 8 hour night.
