solar power for dry camping & cpap machine

Examine the plug in brick carefully. By law the brick must display the power voltage range admitted from the AC plug in inlet to the brick (this cord is usually disconnectable just like a laptop power brick cord)

And then the brick's info with continue on and then list the output voltage and amperage potential of the brick. Aha! This is what you are after. Write down the voltage (12 volts)? and write down the amperage (5 amps)?

Does the brick say 12 volts and 5 amps (very common)?

If yes, you can purchase a power cord that plugs into a cigarette lighter socket, then purchase a long extension (I have encountered ads for 12 feet) cigarette light plus an socket extension cords.

This is a far more practical way than using a PURE SINE WAVE inverter that wastes power converting 10 volts to 120 volts AC then back to 12 volts. The power waste going to inverter is expensive and is sort of nuts...if tour CPAP is indeed 12 volts.

But with a battery conversion the CPAP must be unplugged from the cigarette lighter before starting the engine.

Dear Mexico Wanderer. I also did some wandering in Mexico in my younger years, Yucatan and Oaxaca. Drove my van down there and brought back a load of zapotec rugs and black pottery from Dona Maria.

Regarding my cpap and laptops. The problem I have is that my Thor Wanderer does not have a DC plug inside of it. I have searched and searched. I looked near the TV hoping to find it there, but no suerte! I have lots of AC outlets, and they are in all the right places. I have them on either side of the queen sized bed with nice little table tops to put your CPAP machine. I was devastated the first time I dry camped and the AC outlets had no power (they work just fine when you are plugged into electrical power). Paying an electrician to install USB outlets is an option I suppose, but money is very scarce for me so I am trying to do things on the cheap!
