    12v in in car charger help please



    CLICK HERE TO REMOVE THESE ADVERTS
    I have a Minelab safari metal detector that has a 12v rechargeable battery pack.

    I was looking for an in-car charger (cigarette socket type thing), Minelab do one but its 48!
    The spec is as follows,
    3.5mm jack
    12v 150-200mA

    Ive searched but cant find one with that low a milli-amp rating, I do have one but its 400mA, will this be ok to use?
    Any electrical people able to help please?
    Thanks

    I am sure you can get jack adapters too.
    I, for one, like Roman numerals.

    Yes.

    The more current capacity (amps) then better.
    The polarity + - of the plug that goes into your MD is important.
    And output voltage needs to be correct.

    The Safari is also my weapon of choice ,I would be more worried about damaging the battery pack by not using the correct charger which I assume would be set up for correctly charging the pack and shutting off at a certain voltage to prevent overcharging etc.

    No

    States 9 volts, I understand 12 volts are required.

    Yes it'll be fine, don't worry. The rating is the MAXIMUM it can cope with, the battery in your device will decide how much power it needs (somewhere between 150 and 200mA at a guess!) and sort itself out.
    I'm assuming your one is a cigarette plug and plugs into a normal car socket, BTW!

    Be sure that the input plug to your device is as per the label on it. In the VAST majority of cases, the inner core of the plug is +ve and the outer is -ve, be sure though!
