Doc... this is a BAD idea... I've fried numerous
devices by using the
wrong power rating... even if it was only 1mA off. The voltage almost
never matters... as long as the power is correct. Hope this gets to u
before you fry your machine.
Er... what? The voltage rating is the value you need to worry about.
If you put a 16V supply on a device that needs 5V, you're gonna smoke
the device. As for the current rating, the device will not draw more
current from the PS than it requires, so as long as the supply is rated
at or above your requirements, you're okay.
It also is probably worth pointing out that the definition of "power"
(measured in Watts) is not the same as "current" (measured in amps).
