I was looking for a cable that would work with my CPAP and use a 24V direct output from a 300W ROCKPALS portable generator (https://www. amazon.com/Rockpals-Portable-Generator-Flashlight-Emergency/dp/B07FFNTGZ6). I wanted to use an actual 24V output, not a 12V conversion or worse, a 120V power supply. This is exactly what I needed. I've used it with my CPAP when camping, but it also works in emergencies or during power outages.
