EASYLONGER Car Adapter for CPAP, DC 12/24V Converter CPAP Power Cord, 84W Car Charger with 4 DC CPAP Cables for ResMed S9/ AirSense 10/ AirCurve 10/ AirMini/AirSense 11/ Philips Dreamstation etc

My husband uses a Bi-PAP machine. We often go camping. This adapter works on battery power. It is also useful when we lose power during a storm. This gives us peace of mind as a backup when electricity is not available.

Works perfectly! Well made! Great that it works on several machines!

Bought to use for camping, car camping, and for power outages at home for my ResMed 11, and my DreamStation2. It has two power switches; one on the 12 volt adapter and one on the power block. Likes: It comes with several cords for the different most common CPAP machines, and that each cord/adapter is clearly labeled, not only showing what machine it is for but also the voltage required. It also allows me to power directly from DC without converting from AC, making it more efficient so battery back up lasts longer. So far it seems like it is quality built. Cons: Just two minor ones; you have to manually choose the correct voltage on the transformer, and having two power switches which seems overkill. Overall I am really pleased with my purchase. Make the unit auto detect the proper power setting and it would be five stars.

Have a CPAP and bought a 24v battery pack for road trips or camping? Well... this is the car charger you need for that battery. It has the ability to set up voltage to 24v, allowing you to rapid charge the battery instead of using slower USB-C PD modes that max out at 20v and 5 amps. Add a 24v wall charger and you have the fastest charging possible for your battery (the standard charger that comes with the EasyLonger is only 20v, as is any USB-C charger). Honestly, both should have been included in the EasyLonger package... but at least they're cheap to pick up. For the wall charger, look for "24V 6A 144W AC Power Supply Adapter 6amp 100-240V AC to DC 24 Volt 6Amp 5.5mm x 2.1mm DC Plug" If you pick up a 24v charger rated for only 3 or 4 amps you're going to cook it... those ratings aren't for 100% duty/load. Rule of thumb is to pull at less than 80% the max rating... and the EasyLonger pulls at nearly 4 amps!. Also, the 5.5mm DC barrel connector/plug comes in 2 sizes normally... the EasyLonger uses the smaller inner pin that is 2.1mm (not the fat 2.5mm one).

It works great. I am now able to have my back up CPAP battery plugged into the wall and my CPAP machine at the same time. Now when we have a power outage my CPAP machine will stay on.

This cord work less than two weeks and stopped working in the middle of the night. Was not a good night and am I am not happy with this cord at all!!!

Works wonders on the battery pack. Its upgraded cord are awesome. I love that it connects directly to my aircurve 11.

We had two power outages recentry, and i need my CPAP, so I bought this to cover similar outages. I am happy now, I will be able to sleep if it goes out again, be it fire (like the 2) or hurricane (a constant worry). Well worth the money for the peace of mind.
