My personal laptop is a HP Compaq nx6310. I usually forget to take my laptop's charger when i am taking it to work. Buying a new charger is pretty expense when i enquired. At work i have a dell laptop. I was wondering the dell charger instead of the hp's. In my charger: INPUT: 100-240V ~ 1.6A OUTPUT: 18.5V 3.5A Dell's charger: INPUT: 100-240 V ~1.5A OUTPUT: 19.5V 3.34A I know that there is a difference. But not sure if it can do any harm. Pls reply.
