My PSU is a TrekPow G300 (350W) with 24VDC 3A output. I used this cable to power my Airsense 10.1. In the beginning it didn't work at all. I'm still researching why.2. It's only 3 feet long, so you can't put your power bank on the floor and your Airsense 10 on your bedside table. While I don't care right now, it could be a deal breaker for others.
