Using different ac adapters with varying Volts/Amps
A friend of mine insist that as long as the voltage on an ac adapter matches what the device requires, you can plug it in and see if it works without harming the device. He says that it will either work or it won't work.
Now from what I understand, it may or may not work, yes, but if it DOES work, there could be a chance of the power supply or the device getting too much/too little amperage, causing one of them to 'work harder' and overheat/start fire.
I'm not sure myself on this subject, but my googling-skills apperently seem to be lacking lately.
Can anyone point me to a definitive article/wiki that explains the dangers (if any) of using different ac adapters with varying Amps vs. what the device requires.
