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.

  • The electric potential (volt) of the socket should be within the range of the adapter input (230 is between 110-240).
  • The frequency should likewise fall within the adapter input range.
  • The input current of the adapter should not exceed the rated output of the socket. In your case the input is 2,5A (@230V), the rating of the socket is 6A, so you should be fine. In the case the socket rating would not be sufficient a circuit breaker should pop (because you are exceeding the maximum rating, resulting in a fire risk).
