    Important CarPC Power question

    I have purchased myself a new CarPC its power pack transforms 110v to 12v 4500mA
    and...
    240v to 19v 2950mA

    now if i hookup this carpc strait to my car battery (without putting it through it power pack/transformer) which puts out appx 12.9v at 15-20 A will it be fine or will the amps be to much for it

    what he ment was that you dont have to use the transformer you have. (well really you cant without a inverter.) but if you are going to power it from your 12v car bat. that you should use a DC-DC converter. and there is plenty of info of them in the FAQ. and at the mp3car store.

    I must say that I'm dumbfounded.

    Why would you tell someone "sure, why not!" when you have absolutely no idea what you are talking about?

    FAQ: Power Supplies Explained (Part 1)

    Even more important
    Battery --> Regulator --> startup/shutdown controller --> Power supply --> Computer

    That thread should help...

    Most power supplies listed in the sites store and what not have built in Regulators and startup/shutdown controllers and are power supplies...
