12 volt DC outlet ( lighter type )

Hi To All !

I have sleep apnea, I use a cpap machine at night, it runs on 110 volts AC and 12 volts DC.

I need to install a 12 volt DC outlet ( lighter type ), that way if the electric goes out I will be able to use my cpap. My question is, should I run the wiring from the converter or straight from the battery with a fuse?

Thanks.

Is there a spare fuse position in the converter you can use? I would run from either the battery or the converter, whichever is easier. Just be sure the line is fused somewhere.

What about a small inverter? Then you can skip the 12V altogether.

I would still need 12 volts to run a small inverter.

Yes, off your house battery.

I would say use whichever method is easiest and cleanest for you to install. How much amperage does the CPAP pull at 12 volts?

We take an extra battery in the storage area and DH made an run the wire like this http://www.cpapsupplyusa.com/UV-7019...e-Adapter.aspx through the space between the bed and nightstand and then he can plug his DC attachment from the machine into the plug. He was thinking of drilling a hole in the nightstand paneling to make it more permanent. We don't always travel with the battery in the storage area, it usually is transported in the truck bed.

Hope this helps.
