I have a Lenovo Y510p laptop. It uses a 120W 19.5V 6.15A rated charger and the connecter pin is 5.5x2.5 mm. I can neither find an original Lenovo charger nor a compatible adapter with exact ratings in my locality. My question is can I use a 120W 19V 6.42A adapter for ASUS that has the same connecter pin size of 5.5x2.5 mm? I know the 0.5V difference won't be much and the current rating is >6.15A, so the adapter should work fine. But would it be possible to use it as I can't personally test one and I was thinking of ordering one online.
