    ok another dumb question :Doh:
    in my Hymer i have a few, what look like small cigar lighter sockets. ( i presume these are 12 v, right?)
    also (presumably) the main sockets are 240v and will only work when hooked up, right?)

    therefore do i need to use the cigar sockets when wild off the leisure battery and if so can i run something like the ramoska from them and is there an adapter? for them

    cheers,
    Herbies

    yes yes and via a inverter {depending on power requirement} regards garry

    They are most likely "hella" plugs.. Common in continetal vans and fitted in trucks and on motorbikes.. Like a cigarette plug just smaller..
    Search ebay, loads on there and you can get adaptors..

    They are not cigarette lighter type sockets but are Hella Sockets and use a different plug. Some cigarette plugs have a red cap on the bottom that can be removed to make them into Hella Plugs.

    You need an inverter preferably wired to the leisure battery direct to run 240v appliances. They will drag your battery down quickly.

    Better to use gas and a double skillet or a pan than trying to run mains equipment such as Remoska, slow cooker or pup up toasters.

    A mains caravan kettle will need a 1000w to 1500w inverter. The Remoska is 750w A Pop up toaster is about 1000w

    100w at 12v is about 8 amps draw. Then you need to add the losses incurred by the inverter.

    1000w would be taking about 80 to 100 amps from your battery.

    The maximum current that you can draw from those 12v sockets will be either 10 or 15 amps. That's ok for a light, or charging a phone or laptop - either directly via a 12v charger or via a small inverter. But it's nowhere near enough for anything that uses heat - so forget kettles or any kind of cooking device.

    If you want to run anything more major from the leisure batteries via an inverter larger than about 150W, then you must wire the inverter directly to the battery, not through those sockets.

    It's a job for someone who has a good understanding of autoelectrics.
