DC Power Cord for IntelliPAP 2 CPAP Machines

Thank you for making it clear in you listing that this is a special DC cord made exclusively for the Intellipap 2 machine. I inadvertently purchased the wrong cord twice (described as DC cord for the Intellipap, not Intellipap 2) before I figured this out. After googling "Intellipap 2 cord" I was led to the cpap.com website. Luckily the other vendors refunded my money. This cord works great and recently was used on my camping trip, with a lithium ion power station that featured a cigarette lighter 12 volt output socket. Perfect. Direct DC power consumes less energy, so you don't need the 110 volt power inverter and then step it back down to 12 volts, meaning that you can run your CPAP for longer without recharging your power station.
