Review on High-Quality Talentcell DC 24V Power Cord: 5.5 x 2.1mm Male to DC7406 Male Plug - Ideal for Laptops, Notebooks, S10, and More! by Noah Smith

I found this cable after many hours of searching and researching the connection cable for my ResMed S10 CPAP machine to the solar generator. I found a 300w Rockpals unit with a 24vdc connection. This is the only solar generator I have found that has this connector. With this cable I can connect 300W directly to Airsense 10 and it works great. I plan to try it at home and see how many hours I can go without a full charge. I will be using it for camping so maybe consider a 100w solar panel to extend battery life. Anyway, for those of you with Resmed Airsense CPAP, check out the Rockpals 300W. I am very happy with mine. Get the best price by buying it directly from Rockpals.
