    Hey guys

    I just got a new ex-demo Asus F9S. However It didn't come with a charger.
    I haven't had the chance to test it because I will need to order a new charger.

    We have an Acer Aspire 9800 at home with the same charger socket.

    They are both rated at 19V
    However the ASUS requires an input of 19V, 4.74A and 90W

    While the Acer charger output is:
    19V, 7.11A and 135W

    Will the ASUS get damaged if I attempt to use the Acer charger?

    Thanks

    The Acer sends out 2x the amperage, which as I recall is a true measure of power output. If the plug even fits --- yes, it just might cook it and make a pretty trail of smoke. Its never a good idea to try and use the wrong power supply.

    See BTOTech.com for replacement Asus chargers.

    Don't hold me responsible if you burn your laptop :D but:

    Laptop chargers output DC current, at a fixed voltage. The current (and thereby, the power) will vary according to the needs of the computer. So those current (Amp) and power (Watt) ratings are for maximum current and power, respectively; the only thing that is always fixed and HAS to be the same is the Voltage.

    So, as long as the replacement charger has the same voltage and at least the same max amperage/wattage, you should be fine. These conditions are satisfied in your case.

    If it has a lower amperage/wattage, then you may be able to use as far as the computer doesn't eat more power than the adapter can supply. If it does, you'll burn the adapter / or have other possibly unpleasant random effects. :)

    Awesome I have tried it.

    Thanks guys
    So far so good. No indication of smoke or burning PC parts.

    I guess it makes sense, only the Volts really matter.

    Its the same princilples as a PSU on a desktop really (people getting huge wattage psus, with huge currents on 12V, 9V and 5V rails).

    I was able to rack this little beauty for AUD $300, mind you it was ex-demo and charger-less, but its great value for the price
