I'm using a Dell adapter:
- Input: 100-240V~2.5A(2,5A) 50-60Hz
- Output: 19.5V(19,5V)==6.7A(6,7A)
I always connect it to 230V 50Hz 16A in my home and 6A in my office.
Is it safe for my laptop? Please comment your views.
As long as your adapter input rating matches what comes out of the socket, you should be fine.
