JUYOONJUYOON 12V DC Converter Adapter Car Charger Compatible with Resmed Airsend 11 CPAP Machine, Compatible with Airsend 11 elit dc Converter, Compatible with Airsend 11 AutoSet Power Supply

Purchased the cord to go with a solar power station to avoid losing power through the conversion process. It worked exactly as I hoped and was perfect for my Air Sense 11.

ResMed AirSense 11 user...At home, plugging into the wall (120 volt AC) is no problem. But when camping without access to shore power, what can you do. A battery (preferably lithium) can be a solution, such as a Jackery. However, using a 12V battery through an inverter -- even if it comes with the battery -- is inefficient.Instead, just use this adapter and the 12V DC source from the battery to the CPAP machine.It's been a while since I did the comparison, but I think I was "wasting" 20% of the power when using the 120V inverter vs using the 12V output with this adapter. This means that I can go much longer without needing to recharge the battery (or bring a smaller one). For folks who use the heated hose and/or the humidifier, you may be surprised how much longer your battery will last using 12 volt DC directly!

This thing quit after six nights using my cpap during my trip. It made it impossible to use my cpap until I was able to use my 110v connector.

Bought it quickly for a camping trip and it allowed me to get great rest. No issues with heat or losing power.

Works good.

I use the 12V adapter in my RV when camping. It powers the AirSense 11 without issue.

I have a 1280wh battery power station that I had previously purchased on Amazon (but it is no longer listed on Amazon). The unit has both a 12V cigarette lighter adapter and a 120V plug and a digital meter saying how long the power would last for the current configuration.Last night, as a test, I used this power adapter on my CPAP machine all night while sleeping with the normal humidification I use every night - it had no problems running my AirSense 11. This morning, while breathing into the mask, I checked how many more hours the power supply would last. Then, I switched configurations to using the 120V power cord that came with the AirSense 11 and did the same check of how many hours the power supply would last.The result was the 120V power cord that came with the AirSense 11 would last 15 hours. The JUYOON power cord would last 24 hours.

Works great on my ResMed 11. Just plug into the cigarette lighter and you are good to go. If you are on the go this will work great. I have had no compatibility issues at all.
