    240 to 12v

    One for the electrical folks.

    To get cars onto my table I have car ramps and a 12 volt winch.

    I connect the winch up to a battery,which is ok if the battery is fully charged.

    Is there some way of hooking up the winch to a mains supply,so I don't use a car battery.

    This isn't something that's used every day,just once every few weeks

    depends on the amps it draws
    you could use a large power supply
    like they use for amateur radio

    Due to the high current draw my first though was a lithium battery starter pack.
    Very useful to have around at any time.

    //www.rodsnsods.co.uk/forum/asset.php?fid=247421&uid=1021&d=1589120327. Use a Gunson battery Charger/Starter, mine can start the engine with a flat battery after only a few minutes.
    And if I still worked in Feltham, I'd have brought mine over for you to try it out before you went ahead and bought one.

    Are the little starters only good for one go.the winch runs for a couple of minutes.

    The bigger one would work.

    Though like a normal battery would need to be charged fully to work the winch.thats the problem ,because most times I need to use it nothings charged fully.i do have three phase at home

    I used to have a 12v fridge in my old van that ran off the fag lighter, you could also plug it into a inverter / converter thing that was mains powered, just plug n play. Would something like that work ?

    How about switching to a 240v winch, it may be easier in the long run

    Have a look at the tag on the winch to see what the current rating of the motor is. Then look for a 240/12v power supply unit with about 50% higher rating.

    This one would probsbly be ok at 30 amps; https://gimsonrobotics.co.uk/categor...r-power-supply

    or this one from TLC in slough, https://www.tlc-direct.co.uk/Products/SK650662.html

    Same place for a 40 amp, https://www.tlc-direct.co.uk/Products/SK650664.html

    I picked up a 240 winch from lidle, was about £70 and worth every penny, I have vertically lifted a big block mopar and auto box with no problem so should do what you want with no problem.

    How about a cheap trickle charger permanently wired to a dedicated battery. That way you know its always ready to go
