Hi all...I've never taken my laptop out of the country before and would like to make sure it can take the new voltage/hertz...I will be in the Netherlands which has electricity at 230V and 50Hz

On my laptop it says-
INPUT: 22.5-18V -- 2.7-3.2A

On the power supply "box" it says-
INPUT- 100-240V ~ 50-60Hz 1.4A

Output -- 22-18VDC/2.7-3.2A

Judging from common sense, I'm thinking I won't need more than a plug adapter...am I right?
