I solved the power problem by buying an 12V automotive jump box and use it just for the CPAP (for when I am not on the grid). I then plug it into the 12 volt during the day and it gets charged with everything else.

Can you share info on what this is. I am interested in this.

Thank you

Do a search on Amazon for "auto jump starter" or look for them at Sears, TSC, Lowes, Home Depot or any automotive parts store.

My CPAP plugs into 110 AC with a magic black box that converts the power to 12v DC. I made a cord that has a cigarette lighter on one end and a plug for the CPAP on the other end. The CPAP can be run right from a 12v source this way. The folks at Radio Shack can help with the parts for this cord.

When needed, I plug my CPAP in to the 12v outlet on the jump box at night. Then when you are back on the grid, you can re-charge with the wall wart. Great for 1 or 2 nights.

I have also made a double cord (with Cigarette Lighter Plugs on each end). This can be plugged in between the jump box and the accessory plug in your vehicle. That way, while you are traveling down the road, the jump box will charge. You could also plug it in this way to the 12V accessory plug in the camper when you have the generator running (or on the grid). This will also charge the box.

I also went one step further and took the jump box apart and added a SAE 12V lead so that I can hook it up to my Battery Tender in the garage. It is now always topped off and ready to use around the house or when I need to use it for camping with my CPAP.

I also use my CPAP connected directly to a 12 volt source. I believe if you contact the manufacturer of your specific make & model,you will find that there is a direct 12 volt power cord available, that's what I did for my Respironics Remstar. I use a "dedicated" 35 amp AGM, small footprint battery for mine. It will last 3-4 nights, not using a humidifier.
