    Is it possible to charge a battery via a charger plugged into an inverter within the car?

    My thinking is I have a 100AH aux battery and an inverter that runs off that. I could plug my charger into the inverter and charge my cpap battery as I drive.

    I know that's a round about way of doing things, but I have 3 weekends before we go away so time is getting very tight to buy stuff and get it fitted in time.
    Only just seen the thread- we are having very intermittent reception on the road.

    I run a CPAP machine, wghich runs natively off 12v (no conversion losses) of AGM batteries - uses only 20 to 25 amp hours per night using minimal humidification & pulse dose rather than heated tube.

    Easily recharge each day from either solar or Dc to Dc (or both).

    For fast charging Lithium (LiFePo4) is best but still not cheap to set up. Has the advantage of being lighter weight batteries too.

    Using an inverter run off the crank battery to run a battery charger to charge an auxillary battery is what everone used to do before Dc to Dc chargers came on the market. I did this successfully for years. One disadvantage is that you have 240v in the car when driving. Potential risk of electrocuting folk trying to cut you out of the car after an accident if the 240v cable becomes damaged. Risk is best minimised by keeping the Inverter to charger cable as short as possible, & maybe having a sticker on the outside f the car warning of live 240v.

    Hey Cuppa, thanks for chiming in with your knowledge.

    Running the inverter off the crank battery, I'd not thought of that, not a bad idea. I think I'll go with a lithium 125AH battery and a BCDC1240D and maybe even a solar blanket, got nowhere for panels on the roof.

    Well I went to bite the bullet and get a lithium battery etc etc yesterday, got to the checkout and just couldn't do it. Couldn't justify the expense.

    I'm going with Cuppa's idea and am running the inverter off the crank battery. I think this will serve me well for a while, it's certainly saving me lots of $$$$'s.
