I have been using my 12VDC Respironics CPAP machine (sans humidifier) in our camping trailer for a while now. Last year we did purchase land where we "camp" with the trailer. This gave me access to 120VAC full time, but I wanted to also camp with my hammock. These days going without my CPAP machine is a big no-no, as I tend to just not sleep. Also makes me a bit grumpy for the next day.
I am now planning on a father/daughter camp trip this summer without the trailer, so figuring out my CPAP power and hanging location became a big deal to me. I want to be able to go out for extended camping without having to worry whether my power source will be there or not, so I started exploring the idea of a solar power system to replenish my battery each day after a night running the machine. The battery I picked is really made for camping, so it is a nice little package, but is a Lithium battery. This means that the voltage requirements differ than a Lead Acid type battery (standard car battery). To make sure that I controlled the charge from the solar panel, I needed to buy a controler specific to Lithium battery usage. Also, to make the electrical connections between the solar panel, the controller, and the battery, I found these terminating male and female connectors.
This is what I've done so far:
