PD USB-C 20V DC Coverter Charging Cable Cord Compatible with ResMed AirSense 11 Air 11 Airmini 65W 20W ResMed CPAP to 24V CPAP Battery Backup Adapter Charger Power Supply

This thing has worked great with my Anker C300DC to keep my CPAP working, even through a power outage. So far, only like 1-2 hours, on pure battery, but I immediately stopped using my stock 120VAC adapter at home, exclusively using this at home. Did learn that you HAVE to be careful that the port it plugs into has to be able to support 65w+ regardless of other devices connected. (IE your phone plugged into a "100W" adapter make make the "65W" port on the CHARGER not actually 65w anymore, and then when your cpap tries to run heat to the tube, the humidifier, and the air pump, it resets.

This works perfectly with my AirSense 11. Plugged into a USB C battery and off I went without issue. No setup, no fiddling with settings, nothing. The AirSense didn't care that it was on battery and it worked throughout the night. It's extremely light, making it a nice travel accessory. Now, this itself does not have a battery. If you're going to use this to run the AirSense on a battery backup, make sure it can output the 20v this is asking for and has enough battery life to actually keep it going. A cheap cell phone charger will not be capable of handling this. Personally, I hooked mine up to a 24,000mAh power bank with the ability to put out a max of 140W (well above what this needed) and it got me just over 8 hours of run time with an already warmed up AirSense humidity tank.

I use this on my ResMed AirMini and it works great. I use the Llano 30000mah power bank and can get 7-9 hours of power. Doesn't work with all powerbanks though so just make sure you get the required specced banks.

Bought this to use with my Airmini. Tested it with my first powerbank that met the minimum requirements. It negotiated PD with the powerbank and I was able to start my Airmini, but as soon as the airmini used higher pressure it just died. So I bought a INIU BI-B64 powerbank as it was reported working with this converter. Worked a bit better, but after one night of use it died even more easily with both powerbanks. It now shuts down even on base load from the airmini pump. Trying to return this, but it took to long to get the powerbanks that I needed and with abysmal return policy I can no longer return this product. Even though I was delivered a faulty product

I am shocked at how well this works. My original charger weights 18 oz compared to this one weighing just over 5 oz. Totally impressed with the power and USB-C is a bonus, can just plug into my power brick I bring anyway.

This worked well for my airmini and for my airsense11 machines. No issues!

I've been using this when I travel with a 65w rav power charger and it's done very well. It's ability to charge my pixel 7 and power the CPAP has been a game changer on reducing the number of travel items I need to go with.

I'm giving this 4 stars because they say any 65W PD power supply should work, but I have access to more than one 65W PD capable chargers and it works selectively. I had to go through a lot of them to realize that the power supply should be capable of more than 65W for it to work. Like most people who would buy this, I purchased this for a camping trip so I had to make this work with a power bank. I have a no-name powerbank with 65W PD 3.0 output that has the 20V/3.25A profile. That one didn't work. I have multiple wall chargers that are rated at 96W PD 3.0 and those worked. To make my camping trip possible, I had to buy a new Anker powerbank (Anker Prime Power Bank, 20,000mAh Portable Charger with 200W Output, Smart Digital Display, 2 USB-C and 1 USB-A Port Compatible with iPhone 15/14/13 Series, Samsung, MacBook, Dell, and More https://a.co/d/aLANA7M) . I used this Anker powerbank and with the humdifier on I got 7.5 hours of usage before the power bank ran out of battery. Next night I tried it with the humidifier off and I got 7 hours of usage with 45% battery left. It's really just a matter of using the correct power supply. And chances are that the one you have on hand may not work. It really depends on if you think it's worth spending potentially upwards of $100 more to make this work (bringing up the cost of this solution to $150), or if it's worth buying the $300-$400 power banks made specifically for the ResMed CPAP machines. I chose the Anker power bank because I can use it to charge other devices and I can carry it on flights. The power banks that are made for CPAP machines are rated over 100Wh so you will not be able to take them with you on flights
