CPAP machine and batteries

rickeyleee I use an adapter that you can get for the machine plugs into the cigarett adapter or run one with a line from the batteries, if you buy the battery pack I was told it is very expensive so a 2 battery system gives you enough power to run for days, if you travel every day your 1 battery should do the trick. We just did a trip to Calgary Alberta beginning of April, first night it was -21C had to use the heater and cpap and woke up and tested the batteries and they were still at 12.5 volts, I have 2-31group agm batteries they are charged every day when traveling never had a problem there and back, we also had the heater on in the day to keep the camper a little warm as it was still cold all day 2 and also went down to -11c in Winnipeg Manitoba the second night so it is probably cheaper to just put in a second battery than buy the battery pack.
