What's the risk of using not-the-exact-right power cord?
I found a power cord for a laptop which I had at some point labeled, helpfully, "other." What would happen if I took it to our vacation home and used it on one of our laptops? I mean, if it worked, would it be doing damage?

(54,115 posts)if your device is expecting dc and you give it ac, or vice versa, that could be a disaster. you could fry a board or cause other damage.
if your device is expecting just a few amps and the cord is rated for more, that's no problem.
if your device is expecting more amps than the power cord can handle, that can be a problem.
if the polarity is reversed (+ for -, - for +) that can also be a problem.
in practice, most power cords for laptops are fairly close and largely compatible so it's usually not a problem.
i've mixed and matched plenty, without problem. just know you're taking a chance if you don't look closely at the specs.
