Resmed Airsense 11 DC Power Cord

I don't understand why the price is so high. It's a small DC Power cord that comes connected to an adapter cord that connects to the ResMed Airsense 11. You can buy these separately for less (and even the alternative brands are overpriced). However, it does work well, and I like that it's very short. I tested my ResMed Airsense 11 for two nights connected to my Jackery Explorer 300 with this cord plus its included adapter cord. After two nights of regular sleep, 7:44 the first night and 8:18 the second, my battery still had 45% on it. I was using the ResMed the regular way with the humidifier turned on (some say turn the humidifier off to save power, but it worked well turned on). I'll be able to take this camping. Not sure whether this DC Power cord is any better than less expensive ones, but it works well.

Cord is Very short. I had to use a 12 volt extension cord to make it work in my RV. Disappointed. Would not recommend for RV use unless your 12 volt outlet is close by.

I’ll get the bad out of the way first: 1. There are no specifications listed anywhere on the converter (the large boxy bit). The vast majority of consumer electronics show the voltage and current input/outputs, certifications, such as being UL listed, etc. This thing has nothing, except the EXP PRO” label on the top. Makes it seem like a knock off. I’m not saying it is; I’m simply sharing that every electronic device I’ve ever seen with no spec’s was a cheap Chinese no-name brand. If the cable was all one piece I’d assume this was purpose-built for the Airsense 11, but this has a barrel adapter and a small extension for the S11 plug end with a sticker that states, “DC output cable for Resmed Airsense 11”. 2. The 12VDC plug has a red power light that’s way brighter than it needs to be. It’s not spot-light bright, but it is distracting if you use this at night, nearby. I tested this using an Ecoflow battery bank, which was on my nightstand. I could have put it and the S11 on the floor, but that’s not a good idea. Solution: a small piece of electrical tape. The red power light on the converter is also bright, but not nearly as bad. 3. The cable is very short: ~15” for the converter side and ~17” for the S11 cable side (32” total). This should be apparent from the listing, so this is more of a comment than a con. The good: To keep this short, it works. I plugged it into the 12V port on my Ecoflow battery and the S11 worked fine all night. It feels solidly built and the cables/connectors seem durable. I would recommend this if the above negatives are OK with you. They’re not really a big deal to me, though the spec’s not being listed is annoying.
