The 120v outlets are powered when I hook into shore power. I was hoping the camper battery would power them as well.

What is the purpose, does it require a converter not supplied with your unit?
The 120v AC outlets only work when plugged into shore power or a generator.

UNLESS your RV has an inverter wired inline with the oulets.
Normally only some motorhomes and 5th wheels have such a setup available from the factory.
Such a system requires a large battery bank.

A CONverter does the opposite and all RVS have one.
It converts 120v AC to 12v DC to power the 12v things.
It also will use the 120v AC power to recharge the batteries.

You are correct. You would need an inverter hard wired to outlets or have a transfer switch hardwired.
Mine is setup with a transfer switch. I can turn on my inverter with the remote switch allowing all my 110v outlets/devices to run off batteries. Things to consider are you would need to turn off your electric hot water circuit and converter/battery charger circuit.

Does battery power 110/120 v outlets?

I have been putting money aside for the last year and have purchased a Honda EU2000i generator. I've had this on my wish list for about ten years. That will allow me to charge my CPAP battery easily and quickly (and quietly). :-)

I just read an article about CPAP machines and inverters, most require Pure Sine Wave inverters to operate them. If your thinking about a purchase of one do your research on both the inverter and your CPAP.

Thank you. Yes, I bought a pure sine wave inverter. Works great, but they are pricey.

I have been thinking about this myself. Up until now, I have always had either shore power or in a situation to use the pure sine wave generator all night. Soon we will be taking a trip where I won't be able to run the generator at night. CPAP machines are 12 volts. It doesn't seem efficient to buy pure sine wave inverter only to convert back to 12 volts. I checked with my CPAP supplier about a 12 volt plug. They sell them for $50.00. I was hoping the insurance would pay for it, but no such luck. I am sure Amazon has them cheaper so I will be searching for one soon. According to the supplier, they draw about 5 amps with the humidifier running. I would think using an inverter would draw slightly more.

Most CPap machines will offer a 12 volt cable. Both of my machines run fine directly from the battery. I

I just bought a power cord for my cpap here - http://www.cpap.com/productpage/resp...ower-cord.html. Then I installed a cigarette lighter socket on the side of my bed. Works great.

Sorry the sales person was a bit incorrect, your 12 v batteries will not power the regular house type outlets. And you don't have an inverter in your PUP, unless it is used and previous owner installed one. What you have like all us of is a converter. Where you are plugged into shore power, your outlets will work. Have fun.
