    Can anyone help me please.

    I'm a total novice about electronics, but I would like to know whether
    a portable compressor (used for inflating car tyres) that is powered
    from a car's cigarette lighter can be converted easily to run from the

    Yes, it's quite simple, albeit probably kind of expensive. Well,
    the transformer will be the most expensive part. You need to find out
    how many amps your compressor needs, and size the transformer
    appropriately. Then, you could do it with one diode, but a bridge
    would give you better utilization of the transformer capacity.

    Have Fun!

    1st, you need to find out how much current the compressor draws
    (on the labell) (borrow 20 amp DC ammeter).
    2) Buy a battery charger (second-hand?)
    with a rating of at least that much current
    Now you also have a tool for a dead car battery.
    3) buy a cigarette adapter recepticle (Radio Shack?)
    so you won't have to modify the compressor,
    as Doug pointed out.
