Will a 9 volt 1 amp 17 watt power supply work with NetGear MR814 router?

If not, does anyone know where I can find a cheap power supply in eBay that will work?


I did a test on it and it actually outputs around 11.7 volts. And actually i didn't mean to put in 17 watt, since that was in input, not output.

Update 2:

Also, I heard something about the plug needing to match up with the router positive or negative. Does anyone know anything about that?

    according to this you need at least +12v DC @ 1.2A output


    I would not try to use that 9v adapter. This should work

    12VDC 1500mA AC Adapter



    or if you like ebay :)

    NETGEAR Wireless Router MR814 *POWER ADAPTER* only


    $9.95 + $10 shipping

    That looks like it says 12V @ 1A dc output

    **edit** - as far as polarity goes, the standard is inner barrel (+) and outer barrel (-) and your netgear should adhere to that:

    Information about the Power Adapters on NETGEAR products


    "Plug polarity. There are two terminals in the jack which plugs into your product, postive and negative. The positive terminal “+” is the middle, inside one. The negative terminal “-“ is on the outside. The plug polarity is marked on the power adapter for your convenience. ( For NETGEAR products as of May, 2006 )."

    So the netgear should be compatible with the standard.

    I dont think 9V and 1A outputs 17W.

    But anyway, you should look on the back of the router near the power port and see what voltage and amps it specifies. Or check on the label on the router. If the voltages are the same, then I think you can use the power supply.

    To power a real one thousand watt rms amp might take over a one hundred amperes. At finished power. the super question is are you going to hold it to finished power? no longer likely, that would desire to count on the speaker load you ought to hook up with it…. what amp do you have and what audio equipment do you have?
