Wacom Power Supply

The power adapter to my Wacom tablet was apparently given away with no chances of return. I have several spare adapters laying around but none of them fulfill the 12v .1A requirements of the tablet. Would it do any damage to the tablet if I used a 12v 500mA (.5A) power supply? Or is it time to just order a new power supply from the Wacom website?

    Whoa, what model tablet is it? I always thought they were powered by the USB plug.

    It's an older 12x18 Intuos GD. It plugs in via serial port.

    It won't be providing enough power to the tablet and might cause problems, or it could potentially damage the circuitry (just like a brown out can).

    100mA is less than 500mA. It can supply more than enough current.

    It should work fine.

    Oop, I read it backwards. Provided it is a switching psu, it will be fine. If it can't provide less than its max output, you could damage it.

    It should only draw the current that it needs though, V=IR right?

    If the dc power adapter doesn't have a regulator (like most cheap dc adapters), it could be providing a different (higher) voltage at 100ma than it does at 500ma. The cheap ones are rated so many volts at so many amps and will produce that but vary otherwise.
