Presently enjoying awesome weather in La Penita Mexico. Also getting our first experience with the electricity surges so often talked about when RVing in Mexico
Every night , around 10 pm the EMS surge protector kicks out because power to the park exceeds 132 volts. At around 7am the AC kicks back on. When the EMS kicks the AC off, the inverter delivers 110 V from the Trojan batteries to 3 outlets at the dash area of the motorhome.
Consequently, I have to run an extension cord from the dash to the bedroom for my CPAP needs every night. We plan on being here to end of March.
I have a 110 V outlet in the bedroom but it is not serviced by the inverter. Keeping in mind that we are in small town Mexico, would anyone have any experience with how I might connect it to the inverter?

You could tap into an accessable kitchen outlet that is on the inverter or a bathroom one if it is on the same circuit. You would have to run the same gauge wire under the coach and up into the bedroom and unhook that outlet from the line it is on and hook it into the inverter line. You may have a problem getting the right kind of RV wire in Mexico, their codes and system are not the same as ours, so maybe you could order online and have it shipped to you. Another solution would be to go directly from the inverter to the bedroom, but you would still need to unhook the recepticle from its line first. Hope this helps. DACOTAH

It sounds as though your inverter is intended for just the entertainment systems in the front of the coach, so actually wiring an extra outlet to it may be asking a bt much. But as long as its only the CPAP machine, the load is small.

If you can find where the other circuits tie into the inverter, yu may be able to switch the wire from the bedroom outlet from its present circuit breaker to the inverter panel. But if it isn't real close by, you are going t have to run wire from one to the other. If that's the case, yu may as well do what Dacotah suggested.

Upon pulling old Bedroom TV from small cabinet I discovered there is a 12V outlet available. Since I have 12V power from battery bank when not on shore power I can plug in small inverter that I have for running small appliances. Just a short power cord from there to CPAP and I'm happy.
Thanks for all your input.

My CPAP will run off 12 volts, will yours?

X2 My BiPap will run off of 12vdc. Why use an invertor unless you need to run a humidifier with it?

When you get back to the good old USA, get you a 12v cord.

More battery efficient than an inverter, one less thing monkey with, (or to quit on you). $50-$75 from your provider (no Medicare).

Mine works with a cord that I had in my leftover electronics/misc cord/power supply box.

You can sometimes find one at Goodwill store for $2-$3.

12vdc, usually center pos (+) plug (one that fits into your machine) read the label.
(Don't ask the young checkout girl, she doesn't even know how to make/count change). LOL
