I have a power supply which is 19.5V and 6.15A. My friends power supply or laptop probably broke and his power supply has a 19V and 6.32A. His charger comes with an adapter which fits my plug perfectly, would it hurt if we tested my charger on his laptop?

  • Other than checking polarity of the plug, It should work fine, I have done this many times, if voltage is within 1~2 volts and amperage is same or higher you are ok.

No, that's well within the tolerances of both supply and laptop, you shouldn't have any problems assuming both have the same pin configuration, almost certainly centre-pin positive.

Be aware though that many laptops feature "intelligent" charging which attempts to ensure that an approved supply is being used by interrogating a chip inside the charger. In this case you may be presented with a "this accessory is not supported/may not work" or it may refuse to charge at all.
