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

I am very satisfied with this product, have tested it about 10 times now on 12 Volts. And use RESMED CPAP, 24V input to this.

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

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.

Although this power supply can be used for the (apparently rare) Luna G3, and has the correct voltage and plug size for the React Health/3B unit, there is a small difference between it and the factory power supply.It WILL power the React Health/3B Luna G3 as well as the humidifier, but causes machine-connected heated tubing to show up as "unconnected," meaning you lose the benefit of your heated tubing if that's something you absolutely require. Not necessarily a deal-breaker, but please be aware. I have submitted technical information to the manufacturer, so they may fix it in a later version.That said, the power supply ran an entire 8.5 hours with humidity ON, using a 12v lifep04 battery, so if you don’t need or use heated tubing, it’s dandy.

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).

This was advertised to go with the battery I bought but none of the adapters go to the battery but to the CPAP directly. Worthless to buy with the battery

Took this camping and it really did last for 4 days without using the humidifier function. Did not have to charge it at all though I brought the adaptor just in case.

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.
