    Any thoughts re.charging my 12v golf trolley battery from the cigar socket.just
    for whilst driving home,it will not stay on parked flattenning my battery.
    As I have two towing sockets I intend later to run a live feed from the Fridge
    wire and another to ground this will only charge whilst moving.
    I intend to put a 2A fuse in line with the cigar lighter feed after all if it
    will charge a coolbox it should charge a battery.
    I also posted this on the caravan site,just double checking.Thanks

    Providing that you only connect the spare battery while the engine is
    running you will have no problem.If you leave it on when the engine is
    stopped it will almost certainly discharge the car battery.
    You might need a little more than a 2 amp fuse, if the spare battery is
    discharged you could see quite a high current flowing for a short time, up
    to 10 amps easily.

    Whilst I'm with Bob as regards the intelligebility of the whole I
    reckon most coolboxes will take more than 2 amps. After all thats only
    24W of cooling at 100% efficiency. And a flat battery as Brian said
    will probably take much more than that at first.

    probably churned it out too quick whilst still on line.Sorry
    1.Can you charge a golf trolley battery from a cigar lighter?I now know you can.
    2.Running a live feed from a towbar socket from the 12v caravan fridge is
    normal proceedure when fitting towing sockets,they didn't do it in mine so I was
    asking advice.Others have given it,thanks anyway.

    as noted by my collegues above it depends on the charge rate of the battery
    in question really
    easier option for you would be to purchase a cigar lighter charger adaptor
    for your trolley if possible
    if not them simply use the fridge feed off your white socket and see if its
    depends really on whether you have a split charge relay fitted
