Look at your device and find the power requirement for that device, usually stated in Watts. Let's assume it is 50 watts, the Solix 522 is rated for 299WattHours, so the 522 will power the cpap machine for less than 6 hours. The calculation is (Solix Wh) / (device W) or 299Wh / 50 = 5.98hours. Note that if the cpap periodically uses more than the 50 watts, the runtime is further reduced.
Sorry, there was a problem. Please try again later.It's really going to depend on the machine, as they have different wattage needs. Turning the humidifier off on the machine will also extend the runtime as that feature uses more power. With a typical machine, you should be able to get a full night out of it, but with some perhaps even two. Adding a solar panel so you can charge during the day would help to keep it going much longer of course during longer outages.
