No, none of the 110V outlets will work while on battery power. To run it on AC power, you would either have to get an inverter and some additional battery capacity, or run a generator. Depending on the type of CPAP, it may have a battery pack option or be able to run right off of the 12V system, but you'd have to make sure you have enough battery capacity to run everything on the camper's 12V system as well as the CPAP.
