Computer recharger

Question

Hi, I have a gateway laptop T-6321 . I want to bring it in Europe.(this is where I will use it) . The problem is with the plugin and the different voltage that we use back home. I have a head that I could attach to the plugin but is this going to affect the laptop because of the lower voltage that we have there ? Should I better buy another recharger ? or a head transformer plugin attached on it ?
What would be the best solution ?
