    Power to charge laptop

    Hi, have searched forum and couldn't find an answer to this...

    Is there a way to hook up the laptop powerbrick thing so that I don't need to buy an inverter?

    Laptop runs off 11.4v and I'm planning to use the battery for power on / off so this would just be hardwiring it so that it charges when the engine is running... is this 11.4v dc? how would i check?

    I know I could probably just use an inverter (thing that plugs into cigarette lighter that gives a normal power plug socket) but they are quite big and bulky and don't really want to accomodate one in my car...

    ta peeps

    nope. you'll either need to get a inverter, or use a dc-dc power supply.

    Laptops (and other charging systems) typically don't play nice with inverters.

    You should look for an auto adapter for your laptop.
    If you can't find one, there are Carnetix regulators that output 12vDC that will likely work nicely for you.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    you didn't post the laptop model, so i can't be sure. but it says it outputs 19v instead of 11v.

    Its all coming together nicely now!

    Hardest part seems to be getting a reasonably priced screen!
