CPAP and battery power
My old RV had invertor output next to the bed, the new one does not and there is no handy spot to tap 12V. My idea is this. Buy a 120V relay with double throw 120v contacts. Remove the 12 volt feed fr...

My CPAP is 120v only so I purchased a barely used Respironics RemStar off of Craigslist for $125. It uses a 12v brick power supply. I used a RadioShack 12v universal power supply with the interchangeable tips. Works perfect! Much better than doing a whole bunch of wiring and doesn't pull as much current of having an inverter in the mix.
Nope I need either 12v or 120v. No 12 v available in that area without butchering to get at the reading light fixture wiring. And when boondocking I do not have 120v. That is the issue. Also I spend all winter in Mexico and the power there, via my protector, is variable and clicks on and off all night long, so an auto switchover would be nice.
